Order Code RL33461 Civilian Nuclear Waste Disposal Updated March 14November 26, 2007 Mark Holt Specialist in Energy Policy Resources, Science, and Industry Division Civilian Nuclear Waste Disposal Summary Management of civilian radioactive waste has posed difficult issues for Congress since the beginning of the nuclear power industry in the 1950s. Federal policy is based on the premise that nuclear waste can be disposed of safely, but proposed storage and disposal facilities have frequently been challenged on safety, health, and environmental grounds. Although civilian radioactive waste encompasses a wide range of materials, most of the current debate focuses on highly radioactive spent fuel from nuclear power plants. The Nuclear Waste Policy Act of 1982 (NWPA) calls for disposal of spent nuclear fuel in a deep geologic repository. NWPA established an office in the Department of Energy (DOE) to develop such a repository and required the program’s civilian costs to be covered by a fee on nuclear-generated electricity, paid into the Nuclear Waste Fund. Amendments to NWPA in 1987 restricted DOE’s repository site studies to Yucca Mountain in Nevada. DOE is studying numerous scientific issues at Yucca Mountain in preparing a license application to the Nuclear Regulatory Commission (NRC) for the planned repository. Questions about the site include the likelihood of earthquakes, volcanoes, water infiltration, and human intrusion. NWPA’s goal for starting to load waste into the repository was 1998, but DOE now does not expect to open the Yucca Mountain facility until 2017 at the earliest. DOE plans to submit a license application to NRC by June 30, 2008. The Administration requested $544.5 million for the civilian nuclear waste program for FY2007, $50 million above the FY2006 level. The House-passed FY2007 Energy and Water Development Appropriations Bill (H.R. 5427, H.Rept. 109-474) would have provided $574.5 million for the program, with the additional $30 million to be used for interim waste storage. The Senate Appropriations Committee voted to cut the request to $494.5 million, about the same as the FY2006 funding level, and added statutory provisions authorizing the Secretary of Energy to designate interim storage sites for spent nuclear fuel (S.Rept. 109-274). Because the FY2007 appropriations measure was not enacted by the 109th Congress, funding for the program for the remainder of the fiscal year is being provided by a continuing resolution (P.L. 110-5) at $444.5 million. The Administration is requesting $494.5 million for FY2008Because a regular FY2007 appropriations bill was not enacted by the 109th Congress, FY2007 funding for the nuclear waste program was provided by a continuing resolution (P.L. 110-5) at $444.5 million. The Administration requested $494.5 million for the program for FY2008. The House approved the full request, while the Senate Appropriations Committee voted to hold the program at $446.1 million, about the FY2007 level. FY2008 funding for the program is currently being provided by a continuing resolution (P.L. 110-116) at the FY2007 level. The Administration proposed legislation on March 6, 2007, to repeal the statutory cap on the amount of waste at Yucca Mountain, reduce the scope of environmental reviews for the repository, change budget procedures so that program funding could be increased more easily, exempt nuclear waste sent to Yucca Mountain from disposal requirements under the Resource Conservation and Recovery Act, and allow preemption of state and local transportation requirements. Enactment of the legislation is necessary to meet the new goal of opening the repository by 2017, according to DOE. A similar bill (H.R. 5360, S. 2589) did not pass in the 109th Congress.

The bill would repeal the 70,000 metric ton limit on the amount of waste that can be emplaced at the Department of Energy’s (DOE’s) planned nuclear waste repository at Yucca Mountain, Nevada17 Civilian Nuclear Waste Disposal Most Recent Developments The Department of Energy (DOE) certified on October 19, 2007, that more than 3.5 million documents supporting its planned license application for a high-level nuclear waste repository at Nevada’s Yucca Mountain had been made electronically available to the public as required by the Nuclear Regulatory Commission (NRC). Under NRC regulations, DOE must make the certification at least six months before submitting the repository application to NRC; DOE plans to submit the Yucca Mountain application by June 30, 2008. The State of Nevada, which opposes the Yucca Mountain repository, asked NRC to reject the DOE certification on the grounds that many key technical documents had been excluded. DOE’s current goal for starting nuclear waste shipments to Yucca Mountain is early 2017 — 19 years later than required by the Nuclear Waste Policy Act of 1982 (NWPA). The Bush Administration on March 6, 2007, proposed draft nuclear waste legislation similar to legislation in the 109th Congress that was not enacted (H.R. 5360, S. 2589). DOE contends that its 2017 goal for opening the Yucca Mountain repository cannot be met without the proposed statutory changes in the waste program. The bill would repeal the 70,000 metric ton limit on the amount of waste that can be emplaced at the Department of Energy’s (DOE’s) planned nuclear waste repository at Yucca Mountain — a limit that is expected to be exceeded by currently operating reactors during their lifetimes. The bill also would reduce the scope of environmental reviews for the repository, change the budget scoring of waste fee receipts so that program funding could be increased more easily, exempt nuclear waste sent to Yucca Mountain from disposal requirements under the Resource Conservation and Recovery Act, and allow preemption of state and local transportation requirements. To remove a potential obstacle to new nuclear power plants posed by Yucca Mountain delays, the bill would require the Nuclear Regulatory Commission (NRC) to assume that sufficient disposal capacity will be available for waste produced by new reactors. Notably excluded from the bill is an authorization for interim federal storage of nuclear wasteSeveral of those provisions are included in a bill introduced by Senator Domenici May 23, 2007 (S. 37). President Bush’s FY2008 budget request, submitted to Congress on February 5, 2007, would provide $494.5 million for the DOE civilian nuclear waste program (including Yucca Mountain), $50 million above the FY2007 level. The FY2007 . FY2007 funding for the program is beingwas provided by a continuing resolution (P.L. 110-5) at $444.5 million. The Administration is also requesting $395 million for spent nuclear fuel recycling research (under the DOE nuclear energy research and development program) as part of the Global Nuclear Energy Partnership (GNEP). DOE announced on July 19, 2006, that it would submit a license application to NRC for the planned Yucca Mountain repository by June 30, 2008. At the same time, DOE announced that its new goal for starting nuclear waste shipments to Yucca Mountain would be early 2017 — 19 years later than required by the Nuclear Waste Policy Act of 1982. DOE contends that its proposed nuclear waste legislation must be enacted if the 2017 goal for opening Yucca Mountain is to be met. The Department of the Interior issued two decisions on September 7 to block a private interim spent fuel storage facility in Utah proposed by a nuclear utility consortium called Private Fuel Storage (PFS). NRC had issued a license for the waste facility on February 21, 2006, noting that Interior Department approval would also be required. In the September 7 decisions, the Bureau of Indian Affairs disapproved a proposed lease of tribal trust lands to PFS, and the Bureau of Land Management rejected the necessary rights-of-way to transport waste to the facility. The aboveground PFS facility is intended to store up to 4,000 casks of spent nuclear fuel awaiting planned eventual disposal at Yucca Mountain. CRS-2 $444.5 million. The House on July 17, 2007, approved the full request (H.R. 2641, H.Rept. 110-185), while the Senate Appropriations Committee voted on June 28, 2007, to hold the program at $446.1 million. The Administration also requested $395 million for FY2008 for spent nuclear fuel recycling research (under the DOE nuclear energy research and development CRS-2 program) as part of the Global Nuclear Energy Partnership (GNEP). The House approved $120 million for the program, while the Senate panel recommended $242 million. Introduction Nuclear waste has sometimes been called the Achilles’ heel of the nuclear power industry; much of the controversy over nuclear power centers on the lack of a disposal system for the highly radioactive spent fuel that must be regularly removed from operating reactors. Under the Nuclear Waste Policy Act of 1982 (NWPA) and 1987 amendments, the Department of Energy (DOE) is focusing on Yucca Mountain, Nevada, to house a deep underground repository for spent nuclear fuel and other highly radioactive waste. The state of Nevada has strongly opposed DOE’s efforts on the grounds that the site is unsafe, pointing to potential volcanic activity, earthquakes, water infiltration, underground flooding, nuclear chain reactions, and fossil fuel and mineral deposits that might encourage future human intrusion. Despite those concerns, DOE contends that the scientific evidence indicates that Yucca Mountain is suitable and that licensing of the site by the Nuclear Regulatory Commission (NRC) should proceed. A Draft Environmental Impact Statement (EIS) completed by DOE in July 1999 and finalized in February 2002 recommended that the project proceed as planned. However, DOE now does not expect the planned Yucca Mountain repository to open until 2017 at the earliest, about 19 years later than the 1998 goal specified by NWPA. DOE announced on July 19, 2006, that it would submit an NRC license application — previously planned for 2005 — by June 30, 2008. The safety of geologic disposal of spent nuclear fuel and high-level waste (HLW), as planned in the United States, depends largely on the characteristics of the rock formations from which a repository would be excavated. Because many geologic formations are believed to have remained undisturbed for millions of years, it appeared technically feasible to isolate radioactive materials from the environment until they decayed to safe levels. “There is strong worldwide consensus that the best, safest long-term option for dealing with HLW is geologic isolation,” according to the National National Research Council.1 But, as the Yucca Mountain controversy indicates, scientific confidence about the concept of deep geologic disposal has turned out to be difficult to apply to specific sites. Every high-level waste site that has been proposed by DOE and its predecessor agencies has faced allegations or discovery of unacceptable flaws, such as water intrusion or earthquake vulnerability, that could release radioactivity into the environment. Much of the problem results from the inherent uncertainty involved 1 National Research Council, Board on Radioactive Waste Management, Rethinking High-Level Radioactive Waste Disposal: A Position Statement of the Board on Radioactive Waste Management (1990), p. 2. CRS-3 in predicting waste site performance for the one million years that nuclear waste is to be isolated. The Bush Administration’s Global Nuclear Energy Partnership (GNEP) is intended to address some of those disposal problems by reducing the volume of waste 1 National Research Council, Board on Radioactive Waste Management, Rethinking High-Level Radioactive Waste Disposal: A Position Statement of the Board on Radioactive Waste Management (1990), p. 2. CRS-3 that would be emplaced in a repository and reducing its long-term radioactivity. Under GNEP, spent nuclear fuel would be reprocessed, or recycled, by separating various elements, such as plutonium, that could be made into new fuel and “transmuted” into shorter-lived radioactive isotopes. Spent fuel reprocessing, however, has long been controversial because of the potential weapons use of separated plutonium and cost concerns. Other Programs. Other types of civilian radioactive waste have also generated public controversy, particularly low-level radioactive waste, which is produced by nuclear power plants, medical institutions, industrial operations, and research activities. Civilian low-level waste currently is disposed of in large trenches at sites in South Carolina and Washington state; however. However, the Washington facility does not accept waste from outside its region, and the South Carolina site will be available only to the three members of the Atlantic disposal compact (Connecticut, New Jersey, and South Carolina) after June 30, 2008. The lowest-concentration class of low-level. The lowest-concentration class of lowlevel radioactive waste is also accepted by a Utah commercial disposal facility. Threats by states to close their disposal facilities led to congressional authorization authorization of regional compacts for low-level waste disposal in 1985, although no new sites have been opened by any of the 10 approved disposal compacts. Pursuant to a 2003 Texas statute, an application to build a disposal facility for commercial and federal federal low-level waste in Andrews County, Texas, was filed August 2, 2004, by Waste Waste Control Specialists LLC. Nuclear Utility Lawsuits Nuclear utilities, which pay for most of the high-level waste disposal program through a fee on nuclear power, have sued DOE for failing to begin the removal of spent nuclear fuel from storage at commercial reactors by January 31, 1998, the deadline established by the Nuclear Waste Policy Act. Industry officials contend that total damages for missing the 1998 disposal deadline could eventually reach tens of billions of dollars, assuming that no disposal ever takes place. DOE has been negotiating with various reactor owners since 1999 on the missed nuclear waste deadline and reached its first settlement agreement with a nuclear utility, PECO Energy Co. (now part of Exelon), on July 19, 2000. The agreement allowed PECO to keep up to $80 million in nuclear waste fee revenues during the subsequent 10 years. However, other utilities sued DOE to block the settlement, contending that nuclear waste fees may be used only for the DOE waste program and not as compensation for missing the disposal deadline. The U.S. Court of Appeals for the 11th Circuit agreed, ruling September 24, 2002, that any compensation would have to come from general revenues or other sources than the waste fund. CRS-4 Exelon announced a settlement with the Department of Justice August 10, 2004, in which compensation for the company’s nuclear waste storage costs would be paid from the federal Judgment Fund. Exelon, which operates 17 reactors, calculates that it would be reimbursed $300 million if DOE began taking waste by its previous goal of 2010, and up to $600 million if the schedule slipped to 2015. As noted, DOE now does not expect to begin taking waste until 2017 at the earliest. CRS-4 The U.S. Court of Federal Claims has since ordered more than $250400 million in payments to utilities in several other nuclear waste delay cases. TVA was awarded $34.9 million on January 31, 2006, which was paid from the Judgment Fund in August 2006. Three New England power companies were awarded $142 million on September 30, 2006, and Pacific Gas & Electric Company was awarded $42.7 million on October 13, 2006.2 Damages of $39 million were awarded on December 4, 2006, to the Sacramento Municipal Utility District.3 Xcel Energy was awarded $116 million in September 2007,4 and Entergy was awarded $58.7 million in October 2007.5 Duke Energy announced a settlement with DOE on March 6, 2007, in which the company will receivereceived an initial payment of $56 million and annual reimbursement for for future storage costs.6 More than 60 utilities have sued DOE over the waste disposal delays. DOE disposal delays. By October 2007, $290 million of the awards and settlements had been paid from the Judgment Fund, according to the Congressional Budget Office.7 DOE estimates that the federal government will be liable for $7 billion in utility payments if Yucca Mountain begins operating by 2017 as currently planned, with the liability growing by $500 million for each year of additional delay.4 growing to as much as $11 billion if the repository is delayed to 2020.8 Although some of the program’s delays have been blamed on poor management, DOE contends that tight funding has been a major barrier. DOE cannot spend the nuclear industry’s mandatory waste fees without congressional appropriations, and only about half the total fees collected have been appropriated to the program so far. However, some surplus in the fund may be necessary to pay future nuclear waste 2 Hiruo, Elaine, “Court Awards PG&E Less Than Sought for Spent Fuel Storage Costs,” Nucleonics Week, October 19, 2006, p. 9. 3 “Court Awards $39 Million to SMUD,” NuclearFuel, December 18, 2006, p. 13. 4 Meyers, Mike, “Xcel Wins Suit Over Spent-Fuel Storage,” McClatchy-Tribune Regional News, distributed by Energy Central Professional, September 29, 2007. 5 Hiruo, Elaine, “Court Awards Entergy $58.7 Million for Damages in Spent Fuel Cases,” NuclearFuel, October 22, 2007, p. 3. 6 Hiruo, Elaine, “Duke Receives $56 Million in Spent Fuel Settlement Agreement,” NuclearFuel, March 12, 2007, p. 11. 7 Cawley, Kim, “The Federal Government’s Liabilities Under the Nuclear Waste Policy Act,” Congressional Budget Office, Statement to House Budget Committee, October 4, 2007, p. 8. 8 Statement of Edward F.

The nuclear industry and others have long urged changes in the waste program’s funding mechanism but have consistently been stymiedblocked by budget scoring and policy issues. Nuclear Spent Fuel Legislation Continued delays in the Yucca Mountain project have prompted proposals for a legislative redirection of the nuclear waste program. The Bush Administration proposed draft legislation on March 6, 2007, that would “facilitate the licensing, construction, and operation of the repository by 2017,” according to Energy Secretary Samuel W. Bodman.59 The Administration’s nuclear waste bill is nearly identical to legislation it submitted to the 109th Congress (H.R. 5360, S. 2589) that was not enacted. The bill would reduce the scope of environmental reviews for the repository, change the budget scoring of waste fee receipts so that program funding could be increased more easily, exempt nuclear waste sent to Yucca Mountain from disposal requirements under the Resource Conservation and Recovery Act, and (RCRA), allow preemption of state and local transportation requirements. 2 Hiruo, Elaine, “Court Awards PG&E Less Than Sought for Spent Fuel Storage Costs,” Nucleonics Week, Oct. 19, 2006, p. 9. 3 “Court Awards $39 Million to SMUD,” NuclearFuel, Dec. 18, 2006, p. 13. 4 Hiruo, Elaine, “Duke Receives $56 Million in Spent Fuel Settlement Agreement,” NuclearFuel, Mar. 12, 2007, p. 11. 5 Secretary of Energy, transmittal letter for “Nuclear Fuel Management and Disposal Act,” Mar. 6, 2007. CRS-5 state and local transportation requirements, and permanently withdraw the site from public lands use. To remove a potential obstacle to new nuclear power plants posed by Yucca Mountain delays, the Administration bill would require NRC to assume that sufficient disposal capacity would be available for waste produced by new reactors. (known as the “waste confidence” determination). It also would repeal the 70,000 metric ton limit on the amount of waste that could be emplaced at Yucca Mountain, a limit that is expected to be exceeded by currently operating reactors during their lifetimes. Notably excluded from the bill is an authorization for interim federal storage of nuclear waste pending disposal at Yucca Mountain. Several provisions similar to those in the Administration’s bill are included in legislation introduced by Senator Domenici on May 23, 2007 (S. 37). Called the Nuclear Waste Access to Yucca (NUWAY) Act, S. 37 provides for permanent land withdrawal, repeal of the repository capacity limit, infrastructure and rail line construction, budget scoring changes, and the NRC waste confidence finding. It excludes the Administration’s proposed RCRA exemption but includes an authorization for interim storage of certain waste at Yucca Mountain. At a hearing on S. 2589 by the Senate Energy and Natural Resources Committee on August 3, 2006, DOE Office of Civilian Radioactive Waste Management Director Ward F. Sproat III called enactment of the legislation a prerequisite for opening the Yucca Mountain repository by 2017. “This proposed legislation addresses many of the uncertainties that are currently beyond the control of the Department that have the potential to significantly delay the opening date for the repository,” according to Sproat’s opening statement. J. Barnie Beasley Jr., president of Southern Nuclear 9 Secretary of Energy, transmittal letter for “Nuclear Fuel Management and Disposal Act,” March 6, 2007. CRS-6 Operating Company, expressed “the nuclear energy industry’s strong support” for the legislation. After the latest version of the bill was submitted to the 110th Congress, Sproat warned that if Congress does not lift the Yucca Mountain capacity limit, he will have to recommend that a site search begin for a second repository.610 However, the State of Nevada strongly opposes the legislation. “Now you have before you a bill that attempts, like a cowcatcher on a locomotive, to anticipate and sweep aside every potential health and safety obstacle that could upset the relentless drive to begin receiving highly radioactive waste and spent nuclear fuel at Yucca Mountain in 2017,” said Robert R. Loux, Executive Director of the Nevada Agency for Nuclear Projects, in his opening statement at the August 2006 hearing. Because of delays in the Yucca Mountain project, the Senate Appropriations Committee included statutory authorization for the Secretary of Energy to designate interim storage sites for spent nuclear fuel as part of the FY2007 Energy and Water Development Appropriations bill (H.R. 5427, Sec. 313). However, the 109th Congress adjourned without enacting the measure. The Senate Committee’s provisions would have required the Secretary, after consultation with the governor, to designate a storage site in each state with a nuclear power plant, if feasible, or to designate regional storage facilities. Such sites would have had to be federally owned or able to be purchased by the federal government from a willing seller and could not be located in Nevada or Utah (where a private storage site has been proposed). DOE would have been required to take over all responsibility for spent fuel stored at shutdown reactors, upon the reactor owners’ request. The storage provisions in this section would have been deemed sufficient to satisfy NRC requirements that new nuclear power plants demonstrate the ability to safely dispose of nuclear waste before being licensed to operate. The Senate Appropriations Committee described the interim storage provisions as a “medium term” solution for spent nuclear fuel awaiting disposal at Yucca 6 Hiruo, Elaine, “Hoping to Push Repository Forward, DOE Resends Draft Bill to Congress,” NuclearFuel, March 12, 2007, p. 12. CRS-6 Mountain or reprocessing.7 However, the Coalition of Northeastern Governors contended that fees paid by nuclear power producers should be focused on permanent disposal, rather than being diverted “toward a hastily created network of federal consolidated storage facilities.”8 A subsequent letter from 17 governors called the proposed statutory language “wholly unacceptable to our constituents and us.”9Senator Reid introduced legislation on March 6, 2007, to require commercial nuclear reactor operators to place their spent nuclear fuel into on-site dry storage casks, which would then become the permanent responsibility of DOE (S. 784). Opponents of the proposal contend that it would leave spent fuel at reactor sites indefinitely and undermine the Nuclear Waste Policy Act. However, supporters argue that the waste would be safer in dry storage at reactor sites than if it were shipped across the country to Yucca Mountain. Because of delays in the Yucca Mountain project, the Senate Appropriations Committee included statutory authorization for the Secretary of Energy to designate interim storage sites for spent nuclear fuel as part of the FY2007 Energy and Water Development Appropriations bill (H.R. 5427, Sec. 313). However, the 109th Congress adjourned without enacting the measure. The Senate Committee’s provisions would have required the Secretary, after consultation with the governor, to designate a storage site in each state with a nuclear power plant, if feasible, or to designate regional storage facilities. President Bush recommended the Yucca Mountain site to Congress on February 15, 2002, and Nevada Governor Guinn submitted a notice of disapproval, or “state veto,” April 8, 2002, as allowed by NWPA. The state veto would have blocked further repository development at Yucca Mountain if a resolution approving the site had not been passed by Congress and signed into law within 90 days of continuous session. An approval resolution was signed by President Bush July 23, 2002 (P.L. 107-200).10 Senator Reid introduced legislation on March 6, 2007, to require commercial nuclear reactor operators to place their spent nuclear fuel into on-site dry storage casks, which would then become the permanent responsibility of DOE (S. 784). Opponents of the proposal contend that it would leave spent fuel at reactor sites indefinitely and undermine the Nuclear Waste Policy Act. However, supporters argue that the waste would be safer in dry storage at reactor sites than if it were shipped across the country to Yucca Mountain. Characteristics of Nuclear Waste Radioactive waste is a term that encompasses a broad range of material with widely varying characteristics. Some waste has relatively slight radioactivity and is safe to handle, while other types are intensely hot in both temperature and radioactivity. Some decays to safe levels of radioactivity in a matter of days or weeks, while other types will remain dangerous for thousands of years. Major types of radioactive waste are generally defined by DOE and the Nuclear Regulatory Commission (NRC) as follows: 7 Senate Committee on Appropriations, “Committee Approves Energy and Water Appropriations Bill,” Press Release, June 29, 2006. 8 Coalition of Northeastern Governors, Letter to the Honorable Pete Domenici, Aug. 2, 2006. 9 Office of the Governor, State of Maine, “Governor Opposes Proposed Interim Nuclear Waste Storage Plan,” News Release, Nov. 16, 2006. 1011 10 Hiruo, Elaine, “Hoping to Push Repository Forward, DOE Resends Draft Bill to Congress,” NuclearFuel, March 12, 2007, p. 12. 11 Senator Bingaman introduced the approval resolution in the Senate April 9, 2002 (S.J.Res. 34), and Representative Barton introduced it in the House April 11, 2002 (H.J.Res. 87). The Subcommittee on Energy and Air Quality of the House Committee on Energy and Commerce approved H.J.Res. 87 on April 23 by a 24-2 vote, and the full Committee approved the measure two days later, 41-6 (H.Rept. 107-425). The resolution was passed by the House May 8, 2002, by a vote of 306-117. The Senate Committee on Energy and Natural Resources approved S.J.Res. 34 by a 13-10 vote June 5, 2002 (S.Rept. 107-159). Following a 60-39 vote to consider S.J.Res. 34, the Senate passed H.J.Res. 87 by voice vote July 9, 2002. CRS-7 Characteristics of Nuclear Waste Radioactive waste is a term that encompasses a broad range of material with widely varying characteristics. Some waste has relatively slight radioactivity and is safe to handle, while other types are intensely hot in both temperature and radioactivity. Some decays to safe levels of radioactivity in a matter of days or weeks, while other types will remain dangerous for thousands of years. Major types of radioactive waste are generally defined by DOE and the Nuclear Regulatory Commission (NRC) as follows: Spent nuclear fuel. Fuel rods that have been permanently withdrawn from a nuclear reactor because they can no longer efficiently sustain a nuclear chain reaction (although they contain uranium and plutonium that could be extracted through reprocessing to make new fuel). By far the most radioactive type of civilian nuclear waste, spent fuel contains extremely hot but relatively short-lived fission products (fragments of the nuclei of uranium and other fissile elements) as well as long-lived radionuclides (radioactive atoms) such as plutonium, which remains dangerously radioactive for tens of thousands of years or more. High-level waste. Highly radioactive residue created by spent fuel reprocessing (almost entirely for defense purposes in the United States). High-level waste contains most of the radioactive fission products of spent fuel, but most of the uranium and plutonium usually has been removed for re-use. Enough long-lived radioactive elements remain, however, to require isolation for 10,000 years or more. Transuranic (TRU) waste. Relatively low-activity waste that contains more than a certain level of long-lived elements heavier than uranium (primarily plutonium). Shielding may be required for handling of some types of TRU waste. In the United States, transuranic waste is generated almost entirely by nuclear weapons production processes. Because of the plutonium, long-term isolation is required. TRU waste is being sent to a deep underground repository, the Waste Isolation Pilot Plant (WIPP), near Carlsbad, New Mexico. Low-level waste. Radioactive waste not classified as spent fuel, high-level waste, TRU waste, or byproduct material such as uranium mill tailings (below). Four classes of low-level waste have been established by NRC, ranging from least radioactive and shortest-lived to the longest-lived and most radioactive. Although some types of low-level waste can be more radioactive than some types of high-level waste, in general low-level waste contains relatively low amounts of radioactivity that decays relatively quickly. Low-level waste disposal facilities cannot accept material that exceeds NRC concentration limits. Uranium mill tailings. Sand-like residues remaining from the processing of uranium ore. Such tailings have very low radioactivity but extremely large volumes that can pose a hazard, particularly from radon emissions or groundwater contamination. Mixed waste. High-level, low-level, or TRU waste that contains hazardous non-radioactive waste. Such waste poses serious institutional problems, because the CRS-8 radioactive portion is regulated by DOE or NRC under the Atomic Energy Act, while the Environmental Protection Agency (EPA) regulates the non-radioactive elements under the Resource Conservation and Recovery Act (RCRA). Spent Nuclear Fuel When spent nuclear fuel is removed from a reactor, usually after several years of power production, it is thermally hot and highly radioactive. The spent fuel is in the form of fuel assemblies, which consist of arrays of metal-clad fuel rods 12-15 feet long. CRS-8 A fresh fuel rod, which emits relatively little radioactivity, contains uranium that has been enriched in the isotope U-235 (usually 3%-5%). But after nuclear fission has taken place in the reactor, many of the uranium nuclei in the fuel rods have been split into a variety of highly radioactive fission products; others have absorbed neutrons to become radioactive plutonium, some of which has also split into fission products. Radioactive gases are also contained in the spent fuel rods. Newly withdrawn spent fuel assemblies are stored in deep pools of water adjacent to the reactors to keep them from overheating and to protect workers from radiation. Spent fuel discharged from U.S. commercial nuclear reactors is currently stored at 72 power plant sites around the nation, plus two small central storage facilities. At the end of 2002 (the most recent DOE survey), commercial spent fuel totaled 46,927 metric tons. A typical large commercial nuclear reactor discharges an average of 20-30 metric tons of spent fuel per year — an average of about 2,150 metric tons annually for the entire U.S. nuclear power industry. As a result, the total amount of commercial spent fuel was estimated to exceed 53,000 metric tons by the end of 2006, and projected to reach 62,000 metric tons by 2010, when the Yucca Mountain repository had been planned to open. Including 7,000 metric tons of DOE spent fuel and high-level waste that is also planned for disposal at Yucca Mountain, the total amount would nearly reach NWPA’s 70,000-metric-ton limit by 2010. (For details on current spent fuel storage, see CRS Report RS22001, Spent Nuclear Fuel Storage Locations and Inventory, by Anthony Andrews.) As long as nuclear power continues to be generated, the amounts stored at plant sites will continue to grow until an interim storage facility or a permanent repository can be opened — or until alternative treatment and disposal technology is developed. DOE estimates that the recently updated its estimate of the total amount of commercial spent fuel and other highly radioactive waste may grow to 105,000 metric tons by 2035.11that may eventually require disposal from 105,000 metric tons12 to 130,000 metric tons.13 New storage capacity at operating nuclear plant sites or other locations will be required if DOE is unable to begin accepting waste into its disposal system until 2017 12 DOE Office of Civilian Radioactive Waste Management, OCRWM Annual Report to Congress, Fiscal Year 2002, DOE/RW-0560, October 2003, Appendix C. 13 DOE Office of Civilian Radioactive Waste Management, Draft Supplemental Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada, Summary, DOE/EIS-0250F-S1D, October 2007, p. S-47. CRS-9 or later. Most utilities are expected to construct new dry storage capacity for their older, cooler fuel. On-site dry storage facilities currently in operation or planned typically consist of metal casks or concrete modules. NRC has determined that spent fuel could be stored safely at reactor sites for up to 100 years.1214 The terrorist attacks of September 11, 2001, heightened concerns about the vulnerability of stored spent fuel. Concerns have been raised that an aircraft crash into a reactor’s pool area or sabotage could drain the pool and cause the spent fuel inside to overheat. A report released by NRC January 17, 2001, found that overheating could cause the zirconium alloy cladding of spent fuel to catch fire and release hazardous amounts of radioactivity, although it characterized the probability of such a fire as low. 11 DOE Office of Civilian Radioactive Waste Management, OCRWM Annual Report to Congress, Fiscal Year 2002, DOE/RW-0560, October 2003, Appendix C. 12 Nuclear Regulatory Commission, Waste Confidence Decision Review, 55 Federal Register 38474, Sept. 18, 1990. CRS-9 In a report released April 6, 2005, the National Academy of Sciences (NAS) found that “successful terrorist attacks on spent fuel pools, though difficult, are possible.” To reduce the likelihood of spent fuel cladding fires, the NAS study recommended that hotter and cooler spent fuel assemblies be interspersed throughout spent fuel pools, that spray systems be installed above the pools, and that more fuel be transferred from pools to dry cask storage.1315 NRC has agreed to consider some of the recommendations, although it contends that current security measures would prevent successful attacks. The nuclear industry contends that the several hours required for uncovered spent fuel to heat up enough to catch fire would allow ample time for alternative measures to cool the fuel. The FY2006 Energy and Water appropriations bill (P.L. 109-103) gave NRC an additional $21 million to implement the NAS recommendations. Commercial Low-Level Waste Slightly more than 4 million cubic feet of low-level waste with about 329,000 curies of radioactivity was shipped to commercial disposal sites in 2006, according to DOE.1416 Volumes can vary widely from year to year, based on the status of nuclear decommissioning projects and cleanup activities that can generate especially large quantities. For more background on radioactive waste characteristics, see CRS Report RL32163, Radioactive Waste Streams: An Overview of Waste Classification for Disposal, by Anthony Andrews. 14 Nuclear Regulatory Commission, Waste Confidence Decision Review, 55 Federal Register 38474, September 18, 1990. 15 National Academy of Sciences, Safety and Security of Commercial Spent Nuclear Fuel Storage: Public Report, released April 6, 2005, p. 2. 16 U.S. Department of Energy, Management [http://mims.apps.em.doe.gov/mims.asp#]. Information Manifest System, CRS-10 Current Policy and Regulation Spent fuel and high-level waste are a federal responsibility, while states are authorized to develop disposal facilities for commercial low-level waste. In general, disposal requirements have grown more stringent over the years, in line with overall national environmental policy and heightened concerns about the hazards of radioactivity. Spent Nuclear Fuel Current Program. The Nuclear Waste Policy Act of 1982 (NWPA, P.L. 97-425) established a system for selecting a geologic repository for the permanent disposal of up to 70,000 metric tons (77,000 tons) of spent nuclear fuel and high-level waste. DOE’s Office of Civilian Radioactive Waste Management (OCRWM) was created to carry out the program. The Nuclear Waste Fund, holding receipts from a fee on commercial nuclear power and federal contributions for emplacement of high-level defense waste, was established to pay for the program. 13 National Academy of Sciences, Safety and Security of Commercial Spent Nuclear Fuel Storage: Public Report, released Apr. 6, 2005, p. 2. 14 U.S. Department of Energy, Management [http://mims.apps.em.doe.gov/mims.asp#] Information Manifest System, CRS-10 DOE was required to select three candidate sites for the first national high-level waste repository. After much controversy over DOE’s implementation of NWPA, the act was substantially modified by the Nuclear Waste Policy Amendments Act of 1987 (Title IV, Subtitle A of P.L. 100-203, the Omnibus Budget Reconciliation Act of 1987). Under the amendments, the only candidate site DOE may consider for a permanent high-level waste repository is at Yucca Mountain, Nevada. If that site cannot be licensed, DOE must return to Congress for further instructions. The 1987 amendments also authorized construction of a monitored retrievable storage (MRS) facility to store spent fuel and prepare it for delivery to the repository. But because of fears that the MRS would reduce the need to open the permanent repository and become a de facto repository itself, the law forbids DOE from selecting an MRS site until recommending to the President that a permanent repository be constructed. The repository recommendation occurred in February 2002, but DOE has not announced any plans for an MRS. Waste Facility Schedules. DOE announced on July 19, 2006, that it would submit a license application to NRC for the planned Yucca Mountain repository by June 30, 2008. At the same time, DOE announced that its new goal for starting nuclear waste shipments to Yucca Mountain would be early 2017 — 19 years later than required by the Nuclear Waste Policy Act of 1982. In preparation for filing the Yucca Mountain license application, DOE certified on October 19, 2007, that more than 3.5 million documents supporting the planned application had been made electronically available to the public as required by NRC. Under NRC regulations, DOE must make the document certification at least six months before submitting the repository application. The State of Nevada, which CRS-11 opposes the Yucca Mountain repository, asked NRC to reject the DOE certification on the grounds that many key technical documents had been excluded.17 DOE announced on October 25, 2005, that it would require most spent fuel to be sealed in standardized canisters before shipment to Yucca Mountain. This change would largely eliminate the handling of individual fuel assemblies at the site, but it also helped delay the Yucca Mountain license application. The major activity at the Yucca Mountain site so far has been the construction and operation of an “exploratory studies facility” (ESF) with a 25-foot-diameter tunnel boring machine. The ESF consists primarily of a five-mile tunnel with ramps leading to the surface at its north and south ends. The tunnel boring machine began excavating the north ramp in October 1994 and broke through to the surface at the south entrance April 25, 1997. Underground studies are being conducted at several side alcoves that have been excavated off the main tunnel. DOE completed a “viability assessment” of Yucca Mountain in December 1998, which was followed by a draft environmental impact statement (EIS) for the project in July 1999. DOE issued a preliminary site suitability evaluation August 21, 2001, that found Yucca Mountain could meet EPA and NRC requirements. Energy Secretary Abraham on February 14, 2002, recommended to President Bush that the Yucca Mountain project go forward. At the same time, the Secretary submitted the final EIS (see [http://www.ocrwm.doe.gov/documents/feis_a/ index.htm]) and other supporting materials (for details, see the Yucca Mountain Project home page at [http://www.ocrwm.doe.gov]). As noted previously, President Bush recommended the Yucca Mountain site to Congress the day after the Secretary’s recommendation, and Nevada Governor Guinn subsequently submitted a notice of disapproval, or “state veto,” as allowed by NWPA. An approval CRS-11 resolution passed by the House and Senate to overturn the state veto was signed by the President July 23, 2002 (P.L. 107-200). DOE announced April 8, 2004, that it planned to transport nuclear waste mostly by rail to the planned Yucca Mountain repository. The Record of Decision on the waste transportation mode was published in the Federal Register along with the selection of a corridor in Nevada for a 300-mile rail spur to the Yucca Mountain site. DOE estimated that Yucca Mountain would receive 9,000-10,000 rail shipments and 3,000-3,300 truck shipments over a 24-year period after the repository opened. On October 13, 2006, DOE announced in the Federal Register that a second, shorter rail route to Yucca Mountain would also be considered. However, permission to use tribal land for the shorter route was withdrawn on April 17, 2007, so DOE is again focusing on the 300-mile option. The repository is to be permanently closed after about 100 years of operation, according to DOE’s draft supplemental EIS.18 17 State of Nevada, Office of the Governor, Agency for Nuclear Projects, “Nevada Calls on NRC to Throw Out ‘Defective’ DOE Database Needed for Yucca Mountain Project,” news release, October 19, 2007. 18 U.S. DOE, Draft Supplemental Environmental Impact Statement, op. cit., p.

The quality of scientific work at Yucca Mountain was called into question by DOE’s March 16, 2005, disclosure of e-mails from geologists indicating that some quality assurance documentation had been falsified. DOE issued a technical report in February 2006 that found that previous scientific conclusions about Yucca Mountain had not been affected by the quality assurance problems. However, DOE announced at the same time that some of the previous work would be redone or supplemented.1519 The Government Accountability Office in March 2006 found chronic quality assurance problems in the Yucca Mountain project.1620 Members of the Nevada congressional delegation and state officials have called for the Yucca Mountain project to be suspended and for an independent commission to review all of DOE’s scientific work at Yucca Mountain.1721 The state of Nevada is also fighting DOE in court. A suit filed in June 2002 charged DOE with violating NWPA by relying too strongly on casks and other engineered barriers to prevent radioactive releases, rather than on Yucca Mountain’s natural site characteristics. Another suit, filed January 9, 2003, contended that Congress violated the Constitution in eliminating all candidate waste sites except Yucca Mountain. The U.S. Court of Appeals for the District of Columbia Circuit rejected those challenges July 9, 2004, but it struck down EPA’s 10,000-year regulatory compliance period as too short (discussed in more detail below). Delays in the Yucca Mountain project have prompted congressional interest in alternative nuclear waste management technologies. The FY2006 Energy and Water Development Appropriations Act18Act22 provided $495 million for nuclear waste disposal — $148.5 million from the Nuclear Waste Fund and $346.5 million from the Defense Nuclear Waste Disposal Account. Of the defense waste funding, $50 15 DOE Office of Public Affairs, Technical Report Confirms Reliability of Yucca Mountain Technical Work, Feb. 17, 2006. 16 U.S. Government Accountability Office, Yucca Mountain: Quality Assurance at DOE’s Planned Nuclear Waste Repository Needs Increased Management Attention, GAO-06-313, Mar. 2006, p. 6. 17 Elaine Hiruo, “DOE Sought Help From Scientist Who Wrote E-mails,” NuclearFuel, Apr. 11, 2005, p. 1. 18 H.Rept. 109-275, P.L. 109-103.

Applicants for a recycling facility can receive up to $5 million per site, up to a total of $20 million, to prepare detailed proposals.

CRS-13 The House on May 24, 2006, approved $574.5 million for the nuclear waste program in its version of the FY2007 Energy and Water Development Appropriations Bill (H.R. 5427, H.Rept. 109-474), with the additional $30 million to be used for interim waste storage if authorizing legislation is enacted. The Senate Appropriations Committee voted on June 29, 2006, to cut the waste program request to $494.5 million, about the same as the FY2006 funding level, and added statutory provisions authorizing the Secretary of Energy to designate interim storage sites for spent nuclear fuel (described above). However, as noted, the FY2007 funding measure died in the 109th Congress, and DOE programs arewere under a continuing resolution for the restall of FY2007. DOE’s FY2008 budget request would sharply boost research funding for recycling (also called reprocessing) in the AFCI program — from about $120.0 $167.5 million to $395.0 million — as part of the Global Nuclear Energy Partnership (GNEP). (GNEP). The House approved $120.0 million for the program, while the Senate Appropriations Committee recommended $242.0 million. Private Interim Storage. In response to delays in the federal nuclear waste program, a utility consortium signed an agreement with a Utah Indian tribe on December 27, 1996, to develop a private spent fuel storage facility on tribal land. The Private Fuel Storage (PFS) consortium submitted a license application to NRC on June 25, 1997, and an NRC licensing board recommended approval on February 24, 2005. On September 9, 2005, NRC denied the State of Utah’s final appeals and authorized the NRC staff to issue the license. The 20-year license for storing up to 44,000 tons of spent fuel in dry casks was issued on February 21, 2006, although NRC noted that Interior Department approval would also be required. On September 7, 2006, the Department of the Interior issued two decisions against the PFS project. The Bureau of Indian Affairs disapproved a proposed lease of tribal trust lands to PFS, concluding there was too much risk that the waste could remain at the site indefinitely.2024 The Bureau of Land Management rejected the necessary rights-of-way to transport waste to the facility, concluding that a proposed 19 20 DOE, Spent Nuclear Fuel Recycling Plan, May 2006. rail line would be incompatible with the Cedar Mountain Wilderness Area and that existing roads would be inadequate.25 In reaction to the Interior Department decisions, Senator Hatch, a staunch opponent of the PFS proposal, declared the project “stone cold dead.”26 However, 24 Bureau of Indian Affairs, Record of Decision for the Construction and Operation of an Independent Spent Fuel Storage Installation (ISFSI) on the Reservation of the Skull Valley Band of Goshute Indians (Band) in Tooele County, Utah, Sept. 7, 2006.

CRS-14 a PFS spokesperson said legal challenges to the Interior Department decisions or other steps remained under consideration.2327 The NRC licensing board had determined on March 10, 2003, that the PFS facility should not be licensed without sufficient evidence that it could withstand a crash from fighter jets based nearby. In February 2005, the three-member panel decided 2-1 that most crashes would not breach the storage casks and that the probability of radioactive releases was therefore low enough to allow the facility to be licensed. The U.S. Circuit Court of Appeals for the 10th Circuit on August 4, 2004, struck down several statutes that Utah had enacted to block the PFS project, but the state is appealing the decision. The state also filed a lawsuit in the Court of Appeals for the District of Columbia Circuit on March 6, 2006, to overturn the PFS license.2428 Regulatory Requirements. NWPA requires that high-level waste facilities be licensed by the NRC in accordance with general standards issued by EPA. Under the Energy Policy Act of 1992 (P.L. 102-486), EPA was required to write new standards specifically for Yucca Mountain. NWPA also requires the repository to meet general siting guidelines prepared by DOE and approved by NRC. Transportation of waste to storage and disposal sites is regulated by NRC and the Department of Transportation (DOT). Under NWPA, DOE shipments to Yucca Mountain must use NRC-certified casks and comply with NRC requirements for notifying state and local governments. Yucca Mountain shipments must also follow DOT regulations on routing, placarding, and safety. NRC’s licensing requirements for Yucca Mountain, at 10 CFRC.F.R. 63, require compliance with EPA’s standards (described below) and establish procedures that DOE must follow in seeking a repository license. For example, DOE must conduct a repository performance confirmation program that would indicate whether natural and man-made systems were functioning as intended and assure that other assumptions about repository conditions were accurate. The Energy Policy Act of 1992 (P.L. 102-486) made a number of changes in the nuclear waste regulatory system, particularly that EPA must issue new environmental standards specifically for the Yucca Mountain repository site.

CRS-14 repository standards previously issued and subsequently revised no longer apply to Yucca Mountain. DOE and NRC had complained that some of EPA’s general standards might be impossible or impractical to meet. The new standards, which limit the radiation dose that the repository could impose on individual members of the public, were required to be consistent with the findings of a study by the National Academy of Sciences (NAS), which was issued 27 Telephone conversation with Sue Martin, PFS public affairs consultant, September 19, 2006. 28 LLW Notes, “Utah Challenges License Issuance to PFS,” March/April 2006, p. 16. CRS-15 August 1, 1995.29 August 1, 1995.25 The NAS study recommended that the Yucca Mountain environmental standards establish a limit on risk to individuals near the repository, rather than setting specific limits for the releases of radioactive material or on radioactive doses, as under previous EPA standards. The NAS study also examined the potential for human intrusion into the repository and found no scientific basis for predicting human behavior thousands of years into the future. Pursuant to the Energy Policy Act, EPA published its proposed Yucca Mountain radiation protection standards on August 27, 1999. The proposal would have limited annual radiation doses to 15 millirems for the “reasonably maximally exposed individual,” and to 4 millirems from groundwater exposure, for the first 10,000 years of repository operation. EPA calculated that its standard would result in an annual risk of fatal cancer for the maximally exposed individual of seven chances in a million. The nuclear industry criticized the EPA proposal as being unnecessarily stringent, particularly the groundwater standard. On the other hand, environmental groups contended that the 10,000-year standard proposed by EPA was too short, because DOE had projected that radioactive releases from the repository would peak after about 400,000 years. EPA issued its final Yucca Mountain standards on June 6, 2001. The final standards included most of the major provisions of the proposed version, including the 15 millirem overall exposure limit and the 4 millirem groundwater limit. Despite the Department’s opposition to the EPA standards, DOE’s site suitability evaluation determined that the Yucca Mountain site would be able to meet them. NRC revised its repository regulations September 7, 2001, to conform to the EPA standards. In a ruling that could delay the nuclear waste program, a three-judge U.S. Court of Appeals panel on July 9, 2004, struck down the 10,000-year regulatory compliance period in the EPA and NRC Yucca Mountain standards.2630 The court ruled that the 10,000-year period was inconsistent with the NAS study on which the Energy Policy Act required the Yucca Mountain regulations to be based. In fact, the court found, the NAS study had specifically rejected a 10,000-year compliance period because of analysis that showed peak radioactive exposures from the repository would take place several hundred thousand years in the future. In response to the court decision, EPA proposed a new version of the Yucca Mountain standards on August 9, 2005. The proposal would retain the dose limits 25 National Research Council.

Several alternatives to the geologic disposal of spent fuel have been studied by DOE and its predecessor agencies, as well as technologies that might make waste disposal easier. However, most of these technologies involve large technical obstacles, uncertain costs, and potential public opposition. Among the primary long-term disposal alternatives to geologic repositories are disposal in deep ocean trenches and transport into space, neither of which is currently being studied by DOE. Other technologies have been studied that, while probably not replacing geologic disposal, might make geologic disposal safer and more predictable. Chief among these is the reprocessing or “recycling” of spent fuel so that that plutonium, uranium, and other long-lived radionuclides could be converted to faster-decaying fission products in special nuclear reactors or particle accelerators. The spent fuel recycling provisions in recent Energy and Water Development Appropriations bills and the Administration’s GNEP initiative, discussed above, seem to indicate growing interest in this area. Funding. DOE is seekingrequested $494.5 million in FY2008 for the Office of Civilian Radioactive Waste Management. The request is nearly the same as the FY2006 level and $50 million above FY2007 funding. According to DOE, the FY2008 funding request would allow OCRWM to submit the Yucca Mountain license application to NRC by June 30, 2008; conduct security and safety planning; develop a preliminary transportation plan; and improve site infrastructure and operations.2933 Funding for the program is provided under two appropriations accounts, as shown in Table 1. The Administration is requestingrequested $202.5 million from the Nuclear Waste Fund, which holds the fees paid by nuclear utilities. An additional $292.0 million was requested under the Defense Nuclear Waste Disposal account, which pays for disposal of high-level waste from the nuclear weapons program in the planned Yucca Mountain repository. 27 The House Appropriations Committee on June 6, 2007, recommended approval of the full request (H.R. 2641, H.Rept. 110-185), and the House went along on July 17, 2007. However, the Senate Appropriations Committee voted on June 28 to hold the program at $446.1 million. Although nuclear utilities pay fees to the Nuclear Waste Fund to cover the disposal costs of civilian nuclear spent fuel, DOE cannot spend the money in the fund until it is appropriated by Congress. Through August 31, 2007, utility nuclear waste fees and interest totaled $27.145 billion, of which $6.876 billion had been disbursed 31 Especially high doses at the upper end of the exposure range would raise the mean, or average, more than the median, or the halfway point in the data set. 2832 Office of the Governor, Agency for Nuclear Projects.

The nuclear waste program’s appropriations for FY1983-FY2006 total $9.212 billion, according to DOE, including $2.969 billion for defense waste disposal.30 The DOE Total System Life Cycle Cost Report, issued in May 2001 and updated in September 2003, estimates that the entire nuclear waste program will cost $57.5 billion (in constant 2000 dollars) through 2119.FY2008 House FY2008 Senate Com. —* 378.5 —* —* Transportation — 15.0 — — Program integration — 26.4 — — Program direction — 74.7 — — 444.5 494.5 494.5 446.1 99.0 202.5 202.5 202.5 345.5 292.0 292.0 242.0 — — — 1.6 Total Source of Funding Nuclear Waste Fund appropriations Defense waste appropriations Inyo County (CA) coop. agreement Sources: Appropriations Committee reports, DOE FY2006 Congressional Budget Request. * Subcategories not specified. The DOE Total System Life Cycle Cost Report, issued in May 2001 and updated in September 2003, estimates that the entire nuclear waste program will cost $57.5 billion (in constant 2000 dollars) through 2119. However, a higher DOE estimate of the amount of spent fuel that may be emplaced in Yucca Mountain — if the statutory cap is removed — could increase that cost estimate by 35%, according to program officials.35 Low-Level Radioactive Waste Current Policy. Selecting disposal sites for low-level radioactive waste, which generally consists of low concentrations of relatively short-lived radionuclides, is a state responsibility under the 1980 Low-level Radioactive Waste Policy Act and 1985 amendments. Most states have joined congressionally approved interstate compacts to handle low-level waste disposal, while others are developing single-state disposal sites. Under the 1985 amendments, the nation’s three (at that time) operating commercial low-level waste disposal facilities could start refusing to accept waste from outside their regional interstate compacts after the end of 1992. One site 30 34 DOE, Office of Civilian Radioactive Waste Management, Office of Program Management, Monthly Summary of Program Financial and Budget Information, as of Dec. 31, 2006 August 31, 2007, available at [http://www.ocrwm.doe.gov/about/budget/money.shtml]. CRS-17 35 Hiruo, Elaine, “Yucca’s Total Project Cost Up 35%, Sproat Says,” NuclearFuel, October 8, 2007, p. 1. CRS-18 operating commercial low-level waste disposal facilities could start refusing to accept waste from outside their regional interstate compacts after the end of 1992. One site is currently using that authority and another closed, leaving one open to nationwide disposal of all major types of low-level waste and one open only regionally. A third site, in Utah, has since become available nationwide for most Class A low-level waste. Despite the 1992 deadline, no new disposal sites have been opened. Legislation providing congressional consent to a disposal compact among Texas, Maine, and Vermont was signed by President Clinton September 20, 1998 (P.L. 105-236). However, on October 22, 1998, a proposed disposal site near Sierra Blanca, Texas, was rejected by the Texas Natural Resource Conservation Commission, and Maine has since withdrawn. Texas Governor Perry signed legislation June 20, 2003, authorizing the Texas Commission on Environment Quality to license adjacent disposal facilities for commercial and federally generated low-level waste. Pursuant to that statute, an application to build a disposal facility for commercial and federal low-level waste in Andrews County, Texas, was filed August 2, 2004, by Waste Control Specialists LLC. The Midwestern Compact voted June 26, 1997, to halt development of a disposal facility in Ohio. Nebraska regulators rejected a proposed waste site for the Central Compact December 21, 1998, drawing a lawsuit from five utilities in the region. A U.S. district court judge ruled September 30, 2002, that Nebraska had exercised bad faith in disapproving the site and ordered the state to pay $151 million to the compact. A settlement was reached August 9, 2004, in which Nebraska will pay the compact $140.4 million, and the compact will seek access to the planned Texas disposal facility. Most other regional disposal compacts and individual states that have not joined compacts are making little progress toward finding disposal sites, largely because of public opposition and the continued availability of the disposal facilities in South Carolina and, for most Class A waste, Utah. OneThe disposal facility, at Barnwell, South Carolina, is currently accepting all Class Class A, B, and C low-level waste from most states. The Barnwell facility had stopped stopped accepting waste from outside the Southeast Compact at the end of June 1994. The Southeast Compact Commission in May 1995 twice rejected a South Carolina Carolina proposal to open the Barnwell site to waste generators outside the Southeast and to bar access to North Carolina until that state opened a new regional disposal facility, as required by the compact. The rejection of those proposals led the South Carolina Carolina General Assembly to vote in 1995 to withdraw from the Southeast Compact and and begin accepting waste at Barnwell from all states but North Carolina. North Carolina Carolina withdrew from the Southeast Compact July 26, 1999, a move that prompted a lawsuit from the compact on July 10, 2000. South Carolina joined the Atlantic Compact (formerly the Northeast Compact) with Connecticut and New Jersey on July 1, 2000. Under the compact, South Carolina can limit the use of the Barnwell facility to the three compact members. A state law enacted in June 2000 phases out acceptance of non-compact waste through 2008.June 30, 2008. CRS-19 The only other existing disposal facility for all three major classes of low-level waste is at Hanford, Washington. Controlled by the Northwest Compact, the Hanford site will continue taking waste from the neighboring Rocky Mountain CRS-18 Compact under a contract. Compact under a contract. After the South Carolina facility closes to out-of-region waste, the 36 states and the District of Columbia that are outside the Northwest, Rocky Mountain, and Atlantic Compacts will have no disposal site for Class B and C low-level waste. States barred from access to existing disposal facilities are likely likely to require low-level waste generators to store their waste on site until new disposal disposal sites are available, particularly for Class B and C waste. Regulatory Requirements. Licensing of commercial low-level waste facilities is carried out under the Atomic Energy Act by NRC or by “agreement states” with regulatory programs approved by NRC. NRC regulations governing low-level waste licenses must conform to general environmental protection standards and radiation protection guidelines issued by EPA. Transportation of low-level waste is jointly regulated by NRC and the Department of Transportation. Most states considering new or expanded low-level waste disposal facilities, including Texas and Utah, are agreement states. Most states, both agreement and non-agreement, have established substantially stricter technical requirements for low-level waste disposal than NRC’s, such as banning shallow land burial and requiring concrete bunkers and other engineered barriers. NRC would issue the licenses in non-agreement states. Concluding Discussion Disposal of radioactive waste will be a key issue in the continuing nuclear power debate. Without a national disposal system, spent fuel from nuclear power plants must be stored on-site indefinitely. This situation may raise public concern near proposed reactor sites, particularly at sites without existing reactors where spent nuclear fuel is already stored. Several states have tied approval of new reactors to the availability of waste disposal capacity.3136 Under current law, the federal government’s waste disposal policy is focused on the planned Yucca Mountain repository. Despite presidential and congressional approval for the Yucca Mountain licensing process to go forward, DOE will face relentless opposition from the State of Nevada during NRC licensing proceedings. EPA’s proposed new environmental standards for Yucca Mountain may face legal challenges as well, which could further slow the process. Because of their waste-disposal contracts with DOE, owners of existing reactors are likely to continue seeking damages from the federal government if disposal delays continue. DOE’s 2004 settlement with the nation’s largest nuclear operator, Exelon, could require payments of up to $600 million from the federal judgment fund, and theDOE estimates that payments could rise to $11 billion if Yucca Mountain 36 Lovell, David L., Wisconsin Legislative Council Staff, State Statutes Limiting the Construction of Nuclear Power Plants, October 5, 2006.

The nuclear industry has predicted that future damages could reach tens of billions of dollars if no disposal progress is madethe federal disposal program fails altogether. The Administration’s proposed nuclear waste legislation is intended to remove some of the obstacles to opening Yucca Mountain and to remove the lack of permanent waste disposal as an obstacle to licensing new nuclear power plants. The House and Senate Appropriations Committees in the 109th Congress urged that the 31 Lovell, David L., Wisconsin Legislative Council Staff, State Statutes Limiting the Construction of Nuclear Power Plants, Oct. 5, 2006. CRS-19 federal government provide interim storage of spent nuclear fuel pending a permanent solution, but that option has proven highly controversial in the past. The Administration’s proposed Global Nuclear Energy Partnership would open the door for spent fuel reprocessing as a long-term option for handling nuclear waste. Reprocessing (or recycling) proponents have long contended that direct disposal of spent fuel — as currently planned — would waste a potentially vast energy resource and that reprocessing could reduce the long-term hazard posed by nuclear waste. However, the United States has not pursued commercial reprocessing since the 1970s, because of concerns over nuclear nonproliferation and costs. Heated reaction, both pro and con, to the Administration’s latest initiative indicates that the controversy has not receded in the meantime.
