MOST RECENT DEVELOPMENTS
President Bush’s FY2007 budget request, submitted to Congress on February 6, would
provide $544.5 million for the Department of Energy (DOE) civilian nuclear waste program,
$50 million above the FY2006 level. The FY2006 appropriation sets aside $50 million for
the development of a spent nuclear fuel recycling plan, for which no funding is being sought
for FY2007. However, $250 million for nuclear fuel recycling research is included in the
request for DOE nuclear energy research and development (R&D) as part of a new Global
Nuclear Energy Partnership (GNEP). The Administration also said in the budget request that
it would submit legislation to Congress dealing with nuclear waste regulation and funding,
but provided no details.
DOE announced on October 25, 2005, that it would require most spent fuel to be sealed
in standardized canisters before shipment to a planned national nuclear waste repository at
Yucca Mountain, Nevada, a change that would largely eliminate the handling of individual
fuel assemblies at the site. DOE subsequently informed the Nuclear Regulatory Commission
(NRC) that making those changes to the repository’s operational plans would further delay
submission of a Yucca Mountain license application to NRC. DOE currently has no
announced schedule for the license application, which previously had been planned by 2005.
The Environmental Protection Agency (EPA) on August 9 proposed new standards for
the Yucca Mountain repository that would allow higher radiation exposure after 10,000 years
than during the first 10,000 years of repository operation. The previous EPA standards were
overturned July 9, 2004, by the U.S. Court of Appeals for the District of Columbia Circuit,
which ruled that the regulations’ 10,000-year compliance period was too short. The state of
Nevada has strongly objected to the EPA-proposed rule.
NRC on February 21 issued a license for a private interim waste storage facility in Utah
being developed by a nuclear utility consortium called Private Fuel Storage (PFS). However,
PFS still needs approval from the Bureau of Land Management to widen a highway or build
a railroad to the site. The above-ground PFS facility is intended to store up to 4,000 casks
of spent nuclear fuel awaiting planned eventual disposal at Yucca Mountain.
BACKGROUND AND ANALYSIS
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
CRS-1

IB92059

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 evidence so far indicates that Yucca
Mountain is likely to prove 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 2012 at the earliest, more than 14 years later than the 1998
goal specified by NWPA. DOE currently has no announced schedule for submitting an NRC
license application, which previously had been planned for 2005.
The safety of geologic disposal of 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 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 in predicting waste site performance for the
10,000 years or longer that nuclear waste is to be isolated. Opponents of geologic disposal
have urged greater emphasis on new or alternative technologies that might allow entirely
different approaches to high-level radioactive waste management.
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, the Washington facility does not accept waste from outside its region. The
lowest-concentration class of low-level radioactive waste is also accepted by a Utah
commercial disposal facility, which is no longer seeking approval to receive all major classes
of low-level waste. Threats by states to close their disposal facilities led to congressional
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 low-level
waste in Andrews County, Texas, was filed August 2, 2004, by 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. Claims from more than 20 nuclear utilities are pending.2
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.
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 the previous goal of 2010, and up
to $600 million if the schedule slipped to 2015.
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 disposal costs after today’s nuclear
plants have ceased operation. The nuclear industry and others have long urged changes in
the waste program’s funding mechanism but have consistently been stymied by budget
scoring and policy issues.
Nuclear Spent Fuel Legislation
Continued delays in the Yucca Mountain project have prompted calls for legislative
redirection of the nuclear waste program. In its FY2007 budget submission, DOE announced
that “the administration intends to submit to Congress a legislative proposal to address
regulatory, funding and other issues to allow the Department to move forward with this
critical project.”3 Details of the legislation were not announced, but potential topics include
the EPA’s repository standards, federal interim storage of commercial spent fuel, and the
program’s access to the Nuclear Waste Fund.

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.
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. President Bush signed the resolution July 23, 2002 (P.L. 107-200).
Members of the Nevada and Utah congressional delegations introduced legislation on
December 14, 2005, 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 (H.R. 4538, S. 2099). Opponents of the measure 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 or the proposed Private Fuel Storage
(PFS) site in Utah.
Characteristics of Nuclear Waste
Radioactive waste is a term that encompasses a broad range of material with widely
varying characteristics. Some 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 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.
CRS-4

IB92059
02-24-06
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.
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 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.
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 is expected to exceed
53,000 metric tons by the end of 2005 and 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 amount of commercial spent fuel and other highly radioactive waste may
grow to 105,000 metric tons by 2035.4
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 for another six years or
longer. Most utilities are expected to construct new dry storage capacity for their older 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.5
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 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.
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.6 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) gives NRC an additional $21 million to
implement the NAS recommendations.
Commercial Low-Level Waste
Low-level waste disposed of in commercial sites makes up about a third of all
accumulated low-level waste in the United States; the remaining two-thirds has been
generated by DOE activities and sent to DOE-owned disposal sites. Several million cubic
feet of commercial low-level waste is shipped to disposal sites each year, according to NRC.

projects and cleanup activities that can generate especially large quantities.

Andrews.
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. 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. Upon releasing the civilian nuclear waste program’s
FY2006 budget request on February 7, 2005, DOE officials announced that the opening of
the planned Yucca Mountain repository would be delayed at least two years from the
previous goal of 2010 — and more than 14 years after the statutory deadline of January 1998.
DOE announced on October 25, 2005, that it would require most spent fuel to be sealed
in standardized canisters before shipment to Yucca Mountain, a change that would largely
eliminate the handling of individual fuel assemblies at the site. DOE subsequently informed
CRS-7

IB92059
02-24-06
NRC that the changes would further delay submission of the Yucca Mountain license
application: “Until this plan is approved and these changes have been incorporated into the
project’s baseline design, DOE will be unable to estimate realistically when the license
application will be submitted.”7
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 the President 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 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. The repository is to be permanently closed
in 2116, according to the DOE viability assessment.
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 currently is determining whether the problems affect
the completeness and accuracy of information submitted to NRC in support of the planned
Yucca Mountain license application. 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.8

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.
The most recent, 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).
Nevada also successfully challenged DOE’s June 30, 2004, certification that it had made
all licensing background materials available. NRC requires that such material be available
on its Web-based Licensing Support Network (LSN) at least six months before a repository
application is docketed, so the DOE certification was on the last day that would still have
allowed docketing before the end of 2004. An NRC licensing board ruled August 31, 2004,
that DOE had not yet placed all relevant information onto the system. DOE informed NRC
on November 1, 2005, that the Department “is unable to provide a predicted date for LSN
certification at this time.”9
Delays in the Yucca Mountain project prompted the House Appropriations Committee
to include language in its report on the FY2006 Energy and Water appropriations bill
directing DOE “to begin the movement of spent fuel to centralized interim storage at one or
more DOE sites within fiscal year 2006.”10 The bill as passed by the House (H.R. 2419)
would have added $10 million to the Administration’s nuclear waste funding request for that
purpose. During floor debate, questions arose about potential conflicts between the
committee report language and restrictions on DOE interim storage imposed by NWPA and
state agreements. The Senate-passed version of the bill did not include comparable report
language on spent fuel storage.
The conference agreement on the FY2006 Energy and Water bill (H.Rept. 109-275, P.L.
109-103) provides $500 million for nuclear waste disposal — $150 million from the Nuclear
Waste Fund and $350 million from the Defense Nuclear Waste Disposal Account. Of the
defense waste funding, $50 million is provided for DOE to develop a spent nuclear fuel
recycling plan, in conjunction with a recycling technology development plan required under
the Advanced Fuel Cycle Initiative (AFCI). The detailed program plan is to be submitted by
March 31, 2006, and a “site selection competition” for an integrated reprocessing facility is
to begin by June 30, 2006. A reprocessing site is to be selected in FY2007 and construction
to begin in FY2010. “The site competition should not be limited to DOE sites, but should
be open to a wide range of other possible federal and nonfederal sites on a strictly voluntary
basis,” according to the conference report. Applicants for a reprocessing facility can receive
up to $5 million per site, up to a total of $20 million, to prepare detailed proposals.

DOE is requesting no additional funding for FY2007 for spent fuel recycling in the
nuclear waste program. However, the FY2007 budget request would sharply boost research
funding for recycling (also called reprocessing) in the AFCI program — from $79.2 million
to $243.0 million — as part of the Global Nuclear Energy Partnership (GNEP).
The DOE Total System Life Cycle Cost Report, issued in May 2001 and updated in
September 2003, estimates that the entire program will cost $56 billion (in constant 2000
dollars) through 2119.
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.
Despite the NRC license, the PFS facility still needs approval from the Bureau of Land
Management (BLM) to build a rail line or widen a highway through federal land to transport
waste to the site. BLM officials said in November 2005 that such approval would not be
given until the Department of Defense has studied the impact of any such land-use changes
on nearby military facilities, as required by section 2815 of the National Defense
Authorization Act for FY2000 (P.L. 106-65). That study has reportedly not begun.11 In
addition to the BLM approval, PFS will need approval from the Bureau of Indian Affairs and
the Surface Transportation Board. The NRC license also requires PFS to demonstrate
adequate funding before construction would be allowed. No contracts to store waste at the
PFS site have been announced.
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.
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 CFR 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. General EPA 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 August 1, 1995.12 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. The most significant changes
in the final rules were to require that compliance be demonstrated about one mile closer to
the repository and to double the amount of groundwater that would be analyzed. 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 panel of the U.S.
Court of Appeals for the District of Columbia Circuit on July 9, 2004, struck down the
10,000-year regulatory compliance period in the EPA and NRC Yucca Mountain standards.
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 of the previous
standard for the first 10,000 years but allow a higher annual dose of 350 millirems for the
period of 10,000 years through 1 million years. The Final Environmental Impact Statement
for the Yucca Mountain repository estimates that mean peak doses — occurring after
400,000 years — would be about 150 millirems (Volume 1, Chapter 5). EPA also is
proposing to base the new Yucca Mountain standard on the median dose, rather than the
mean, potentially making it easier to meet. Nevada state officials called EPA’s proposed
standard far too lenient and charged that it was “unlawful and arbitrary.”13
Alternative Technologies. 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 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 the FY2006 Energy
and Water Development Appropriations bill and the Administration’s GNEP initiative,
discussed above, seem to indicate growing interest in this area.
Funding. DOE is requesting $544.5 million in FY2007 for the Office of Civilian
Radioactive Waste Management. The request is 10% above the FY2006 appropriation of
$495 million but nearly $30 million below the FY2005 level, when the program had
anticipated a rapid funding escalation to open the Yucca Mountain repository by 2010.
According to DOE, the FY2007 funding request will allow OCRWM to continue revising
the Yucca Mountain license application to reflect the recently announced canistered fuel
concept, correct quality assurance problems, and meet the new EPA environmental standards.
However, there is no announced target date for completing the license application. A
significant funding increase for transportation would allow completion of an environmental

which holds the fees paid by nuclear utilities. An additional $388.1 million is requested
under the Defense Nuclear Waste Disposal account, which pays for disposal of high-level

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 mid-FY2005, utility nuclear waste fees and interest
totaled $23.222 billion, of which $6.272 billion had been disbursed to the waste disposal
program, according to DOE’s program summary report (see [http://www.ocrwm.
doe.gov/pm/budget/]), leaving a balance of $16.950 billion in the Nuclear Waste Fund. The
nuclear waste program’s appropriations for FY1983-FY2006 total $9.143 billion, according
to DOE, including $2.920 billion for defense waste disposal.
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
14 DOE, FY2007 Congressional Budget, vol. 4, p. 566.
CRS-13

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 is currently using that authority and
another closed, leaving one open to nationwide disposal of all major types of low-level
waste. 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 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.
One disposal facility, at Barnwell, South Carolina, is currently accepting all Class A,
B and C low-level waste from most states. The Barnwell facility had 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 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 General Assembly to vote in 1995 to withdraw from the
Southeast Compact and begin accepting waste at Barnwell from all states but North Carolina.
North 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.
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 Compact under a contract.
States barred from access to existing disposal facilities are likely to require low-level waste
generators to store their waste on site until new 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.
