Nuclear Energy: Overview of Congressional Issues

Summary
The policy debate over the role of nuclear power in the nation’s energy mix is rooted in the
technology’s fundamental characteristics. Nuclear reactors can produce potentially vast amounts
of energy with relatively low consumption of natural resources and emissions of greenhouse
gases and other pollutants. However, facilities that produce nuclear fuel for civilian power
reactors can also produce materials for nuclear weapons. The process of nuclear fission (splitting
of atomic nuclei) to generate power also results in the production of radioactive material that
must be contained and can remain hazardous for thousands of years. How to manage the weapons
proliferation and safety risks of nuclear power, or whether the benefits of nuclear power are worth
those risks, are issues that have long been debated in Congress.
The 100 licensed nuclear power reactors at 62 sites in the United States generate about 20% of
the nation’s electricity. Five new reactors are currently under construction. About a dozen more
are planned, but whether they move forward will depend largely on their economic
competitiveness with natural gas and coal plants. Throughout the world, 435 reactors are
currently in service, and 71 more are under construction.
The March 2011 disaster at the Fukushima Dai-ichi nuclear power plant in Japan increased
attention to nuclear safety throughout the world. The U.S. Nuclear Regulatory Commission
(NRC), which issues and enforces nuclear safety requirements, established a task force to identify
lessons from Fukushima applicable to U.S. reactors. The task force’s report led to NRC’s first
Fukushima-related regulatory requirements on March 12, 2012. Several other countries, such as
Germany and Japan, eliminated or reduced their planned future reliance on nuclear power after
the accident.
Highly radioactive spent nuclear fuel that is regularly removed from nuclear power plants is
currently stored at plant sites in the United States. Plans for a permanent underground repository
at Yucca Mountain, NV, were abandoned by the Obama Administration, although that decision is
being challenged in court. The Obama Administration appointed the Blue Ribbon Commission on
America’s Nuclear Future to recommend an alternative nuclear waste policy. In response to the
Commission’s recommendations, the Department of Energy (DOE) issued a new waste strategy
in January 2013 that calls for the selection of new candidate sites for nuclear waste storage and
disposal facilities through a “consent-based” process and for a surface storage pilot facility to
open by 2021.
The level of security that must be provided at nuclear power plants has been a high-profile issue
since the 9/11 terrorist attacks on the United States in 2001. Since those attacks, NRC issued a
series of orders and regulations that substantially increased nuclear plant security requirements,
although industry critics contend that those measures are still insufficient.
Encouraging exports of U.S. civilian nuclear products, services, and technology while making
sure they are not used for foreign nuclear weapons programs has long been a fundamental goal of
U.S. nuclear energy policy. Recent proposals to build nuclear power plants in several countries in
the less developed world, including the Middle East, have prompted concerns that international
controls may prove inadequate.

Nuclear Energy: Overview of Congressional Issues

Synthesis of Key Issues
The long-running policy debate over the future of nuclear energy is rooted in the technology’s
inherent characteristics. Initially developed for its unprecedented destructive power during World
War II, nuclear energy seemed to hold equal promise after the war as a way of providing limitless
energy to all mankind. International diplomacy has focused ever since on finding institutional
mechanisms for spreading the perceived benefits of nuclear energy throughout the world while
preventing the technology from being used for the proliferation of nuclear weapons. Much of this
international effort is focused on key nuclear fuel cycle facilities—plants for enriching uranium in
the fissile isotope U-235 and for separating plutonium from irradiated nuclear fuel. Such plants
can be used to produce civilian nuclear reactor fuel as well as fissile material for nuclear
warheads.
Yet even the use of nuclear power solely for peaceful energy production has proven intrinsically
controversial. The harnessing of nuclear fission in a reactor creates highly radioactive materials
that must be kept from overheating and escaping from the reactor building, as occurred during the
disasters at Fukushima and Chernobyl. Spent nuclear fuel that is regularly removed from reactors
during refueling must be isolated from the environment for up to a million years. Potential
technologies to reduce nuclear waste through recycling usually involve separating plutonium that
could be used for nuclear weapons and would still leave substantial amounts of radioactive waste
to be stored and disposed of. Long-term storage and disposal sites for nuclear waste have proven
difficult to develop throughout the world, as illustrated by the Obama Administration’s
cancellation of the proposed U.S. waste repository at Yucca Mountain, NV.
The March 2011 disaster at Japan’s Fukushima Dai-ichi nuclear power plant, which forced the
evacuation of areas as far as 30 miles away, has slowed nuclear power expansion plans around the
world, particularly in Japan and Western Europe. However, dozens of new reactors are still being
planned and built in China, India, Eastern Europe, and elsewhere.1 In these areas, nuclear power’s
initial promise of generating large amounts of electricity without the need for often-imported
fossil fuels, along with the more recent desire to reduce greenhouse gas emissions, remains a
compelling motivation.
With 100 licensed reactors, the United States has the largest nuclear power industry in the world.
But U.S. nuclear power growth has been largely stagnant for the past two decades, as natural gas
has captured most of the market for new electric generating capacity.2 Congress enacted
incentives for new nuclear plants in the Energy Policy Act of 2005 (P.L. 109-58), including
production tax credits, loan guarantees, and insurance against regulatory delays. Those incentives,
combined with rising natural gas prices and concerns about federal restrictions on carbon dioxide
emissions, prompted industry plans by late 2009 for up to 30 new nuclear power reactors in the
United States.3 However, falling natural gas prices and the defeat of greenhouse gas legislation in
the 111th Congress have put many of those projects on hold. Currently, four new reactors, in
Georgia and South Carolina, are under construction, and an older reactor on which construction

had been suspended for two decades is now being completed in Tennessee. A variety of incentives
to renew the growth of nuclear power have been proposed, including a plan by President Obama
to include nuclear power, along with natural gas and advanced coal technologies, in a federal
mandate for the production of “clean energy.”
Existing U.S. nuclear power plants are facing difficult competition from natural gas and
renewable energy. Four U.S. reactors were permanently closed in 2013, and the shutdown of a
fifth unit was announced for late 2014. Three of those units closed because of the need for
expensive repairs, while the other two were operating well but could not compete in their local
wholesale electricity markets. All five units had substantial time remaining on their initial 40-year
operating licenses or had received or applied for 20-year license extensions from the Nuclear
Regulatory Commission (NRC). The shutdowns prompted widespread discussion about the future
of other aging U.S. reactors. The extent to which the growth of nuclear power should be
encouraged in the United States and around the world will continue to be a major component of
the U.S. energy policy debate. Questions for Congress will include the implementation of policies
to encourage or discourage nuclear power, post-Fukushima safety standards, development of new
nuclear power and fuel cycle technologies, and nuclear waste management strategies.
Basic Facts and Statistics
The 100 licensed nuclear power reactors at 62 sites in the United States generate about 20% of
the nation’s electricity. The oldest of today’s operating reactors were licensed in 1969, and the
most recent was in 1996. The reactors were initially licensed to operate for 40 years, but 80%
have received or applied for 20-year license renewals by NRC. Under the current mixture of 40-
and 60-year licenses, 33 reactors would have to shut down by 2030 and the rest by 2049.4
Whether new reactors will be constructed to replace the existing fleet or even to expand nuclear
power’s market share will depend largely on costs. The cost of building and operating a new
nuclear power plant in the United States is generally estimated to be significantly higher than
natural gas combined-cycle plants (which use both combustion and steam turbines) and somewhat
above conventional coal-fired plants. For example, the Energy Information Administration (EIA)
estimates that electricity generation from a nuclear power plant coming on line in 2018 would
cost 10.8 cents per kilowatt-hour (kwh), while advanced combined-cycle gas would cost 6.6
cents/kwh, and conventional coal would cost 10.0 cents/kwh. EIA estimates that onshore wind
would cost 8.7 cents/kwh, offshore wind 22.2 cents/kwh, and solar photovoltaic 14.4 cents/kwh.5
Such estimates depend on a wide range of variables, however, such as future fuel costs and
environmental regulations. Targeted tax credits and other incentives for specific technologies,
which are not included in the EIA estimates, would also affect nuclear power’s economic
competitiveness.

Nuclear Energy: Overview of Congressional Issues

As noted above, the United States currently has five reactors under construction. They are
scheduled to begin operating in 2015 through 2018.6 Licenses to build and operate 12 additional
reactors are currently pending at NRC, although some of their review schedules are uncertain.7 If
those additional U.S. reactors are licensed and built, they could begin coming on line in the early
2020s.
Throughout the world, 435 reactors are currently in service or operable, and 71 more are under
construction. France is the most heavily nuclear-reliant country in the world, with 58 reactors
generating 75% of the country’s electricity in 2012. Thirty countries in 2012 generated at least
some of their electricity from nuclear power. After the Fukushima accident, Germany, which had
previously generated about 30% of its electricity with nuclear power, closed eight of the country’s
17 power reactors and decided to shut the remainder by 2022.8 Japan, which had also generated
about 30% of its electricity with nuclear power and had planned to raise that level to 50%, is
reconsidering its energy policy. None of Japan’s 48 operable reactors is currently running. Safety
improvements in response to the tsunami are currently being implemented, and 17 reactors are
undergoing regulatory reviews for possible restart. It is not clear how many of the operable
reactors will ultimately seek restart approval.
Major Nuclear Energy Issues
Safety
The Fukushima Dai-ichi disaster, triggered by a huge earthquake and tsunami, greatly increased
concerns about safety in the nuclear policy debate. The accident clearly demonstrated the
potential consequences of a total loss of power (or “station blackout”) at today’s commercial
nuclear plants. Even when a reactor shuts down, as the Fukushima plant did after the initial
earthquake, residual radioactivity in the reactor core continues to generate heat that must be
removed, typically by electrically driven or controlled cooling systems. When the tsunami
knocked out power at three of the Fukushima reactors, the buildup of heat and pressure became
so great that it melted the reactors’ nuclear fuel and exceeded the limits of their containment
structures. Cooling was also lost in Fukushima’s spent fuel storage pools, causing concern that
they could overheat, although later examination indicated that they did not.
Safety requirements for nuclear power plants are established and enforced in the United States by
NRC, an independent regulatory commission. NRC safety regulations address the effects of
external events such as earthquakes and floods, equipment failure such as breaks in coolant pipes,
and other problems that could lead to radioactive releases into the environment. Critics of nuclear
power contend that NRC is often reluctant to impose necessary safety requirements that would be
costly or disruptive to the nuclear industry. However, the industry has frequently contended that

costly safety proposals are unnecessary and would not significantly increase large existing safety
margins.
Recent Events
Following the Fukushima disaster, NRC established a task force to identify lessons applicable to
U.S. reactors and recommend safety improvements. The task force’s report led to NRC’s first
Fukushima-related regulatory requirements, on March 12, 2012. NRC ordered all reactors to
develop strategies to maintain cooling and containment integrity during external events, such as
floods and earthquakes, that were more severe than anticipated by the plants’ designs (“beyond
design basis”). In addition, NRC required that U.S. reactors of similar design to the Fukushima
reactors have “reliable hardened vents” to remove excess pressure from their primary
containments, and that better instrumentation be installed to monitor the condition of spent fuel
pools during accidents.9 The NRC commissioners on March 19, 2013, required NRC staff to
study whether to require the newly mandated containment vents to include filters or other means
to reduce the release of radioactive material if the vents have to be used. The idea of requiring
filters had drawn praise from nuclear critics but opposition from the industry on cost grounds.10

Radioactive Waste
Highly radioactive spent nuclear fuel must regularly be removed from operating reactors and
stored in adjacent pools of water. After several years of cooling, the spent fuel can be placed in
dry casks for storage elsewhere on the plant site. When existing U.S. reactors were built, spent
fuel had been expected to be taken away for reprocessing (separation of plutonium and uranium
to make new fuel) or permanent disposal. However, reprocessing has not become commercialized
in the United States, for economic and nonproliferation reasons, and central waste storage and
disposal facilities have proven difficult to site. As a result, the vast majority of U.S. commercial
spent fuel remains at the nuclear plants where it was generated—totaling 71,775 metric tons in
2013 and rising at the rate of about 2,000 metric tons per year.11
Recent Events
The Nuclear Waste Policy Act (P.L. 97-425, NWPA), as amended in 1987, named Yucca
Mountain, NV, as the nation’s sole candidate site for a permanent high-level nuclear waste
repository. However, the Obama Administration decided to halt the Yucca Mountain project and
appointed the Blue Ribbon Commission on America’s Nuclear Future to recommend an
alternative policy. The Commission issued its final report in January 2012, and the Department of
Energy (DOE) responded in January 2013 with a new waste strategy that calls for a “consent-
based” process to select nuclear waste storage and disposal sites and for a surface storage pilot

facility to open by 2021.12 A federal appeals court on August 13, 2013, ordered NRC to continue
the Yucca Mountain licensing process with previously appropriated funds.13 NRC responded
November 18, 2013, by directing the agency’s staff to complete the Yucca Mountain safety
evaluation report, a key document that would provide the staff’s conclusions about whether the
proposed repository could be licensed.
Selected Congressional Action
No More Excuses Energy Act of 2013 (H.R. 2081, Thornberry)
Includes provisions to prohibit NRC from considering nuclear waste storage when licensing new
nuclear facilities, and to establish a tax credit for obtaining nuclear component manufacturing
certification. Introduced May 21, 2013; referred to multiple committees.
Dry Cask Storage Act (H.R. 3354, Engel)
Requires spent fuel at nuclear power plants to be moved from spent fuel pools to dry casks after it
has sufficiently cooled. Costs of the fuel transfers would be offset by a reduction in nuclear waste
fees owed to the federal government. Introduced October 28, 2013; referred to Committee on

Federal Support and Incentives
Congress has long debated the role that nuclear power should play in meeting national energy and
environmental goals. Nuclear power supporters generally point to the technology as crucial for
providing a secure, domestic source of energy with low greenhouse gas and other emissions.
Opponents generally counter that safety and proliferation risks, nuclear waste hazards, and high
costs outweigh those benefits. The debate over nuclear power’s role often focuses on the level of
federal support that should be provided to encourage the construction of new nuclear plants,
through such mechanisms as loan guarantees, tax credits, clean energy mandates, and liability
limits under the Price-Anderson Act. Because of the relatively high cost of new nuclear reactors,
especially compared with natural gas plants, the level of federal support is expected to be a key
determinant of the future growth or decline of nuclear power in the United States. Federal funding
for nuclear energy research and development, along with related infrastructure and security, is
debated annually in Congress as part of the Energy and Water Development appropriations bill.
DOE nuclear energy funding totals $888.4 million for FY2014, while for FY2015 the President is
requesting a reduction to $863.4 million.
Recent Events
One nuclear power project, consisting of two new reactors at the Vogtle plant in Georgia, received
a conditional commitment from DOE for an $8.33 billion loan guarantee in February 2010, as
authorized by Section 1703 of the Energy Policy Act of 2005 (P.L. 109-58). Energy Secretary
Ernest Moniz announced the issuance of $6.5 billion in loan guarantees on February 19, 2014, to
two of the three utility partners in the project, Georgia Power and Oglethorpe Power. An
additional $1.8 billion loan guarantee for another partner, Municipal Electric Authority of
Georgia, is still pending. No other planned nuclear plants have received conditional commitments
for DOE loan guarantees.

Security and Emergency Response
The level of security that must be provided at nuclear power plants has been a high-profile issue
since the 9/11 terrorist attacks on the United States in 2001. Since those attacks, NRC issued a
series of orders and regulations that substantially increased nuclear plant security requirements,
although industry critics contend that those measures are still insufficient. Key measures include
an increase in the level of attacks that nuclear plant security forces must be able to repel,
requirements for mitigating the effects of large fires and explosions, and a requirement that new
reactors be capable of withstanding aircraft crashes without releasing radioactive material. NRC
also modified its planning requirements for evacuations and other emergency responses after the
9/11 attacks, and the Fukushima disaster illustrated the importance of emergency response to
radioactive releases from any cause.
Recent Events
NRC issued wide-ranging revisions to its emergency preparedness regulations on November 1,
2011, dealing with duties of emergency personnel and the inclusion of hostile actions in
emergency planning drills.14 In response to Fukushima, NRC staff recommended that nuclear
emergency plans be required to address events affecting multiple reactors and prolonged station
blackout. NRC told nuclear power plants on March 12, 2012, to provide specific information and
analysis on those issues.15

Nuclear Weapons Nonproliferation
Encouraging exports of U.S. civilian nuclear products, services, and technology while making
sure they are not used for foreign nuclear weapons programs has long been a fundamental goal of
U.S. nuclear energy policy. International controls and inspections are intended to ensure the
peaceful use of civilian nuclear facilities and prevent the proliferation of nuclear weapons.
However, recent proposals to build nuclear power plants in as many as 18 countries16 that have
not previously used nuclear energy, including several in the Middle East and elsewhere in the less
developed world, have prompted concerns that international controls may prove inadequate.
Numerous recommendations have been made in the United States and elsewhere to create new
incentives for nations to forgo the development of uranium enrichment and spent nuclear fuel
reprocessing facilities that could produce weapons materials as well as civilian nuclear fuel.

Iran is currently the prime example of the tension between peaceful and weapons uses of nuclear
technology. Of particular concern is a growing Iranian uranium enrichment program, which Iran
contends is solely for peaceful purposes but which the United States and other countries suspect
is for producing weapons material. The U.N. Security Council has imposed sanctions and passed
several resolutions calling on Iran to suspend its enrichment program and other sensitive nuclear
activities. Nevertheless, Iran continues to advance its nuclear program.

2014, has also been affected by nonproliferation issues. South Korea would like to include
advance U.S. consent for spent fuel reprocessing and uranium enrichment, but the United States
is concerned about the precedent that such an agreement might set and how it would affect other
ongoing issues on the Korean peninsula. Legislation authorizing the President to extend the
existing nuclear cooperation agreement by two years was signed into law on February 12, 2014
(P.L. 113-81), allowing more time to negotiate a new, long-term agreement.
Selected Congressional Action

Hearing: Civilian Nuclear Cooperation Agreements
Hearing by the Senate Committee on Foreign Relations, January 30, 2014. Examined whether
U.S. nuclear cooperation agreements should require cooperating countries to forgo uranium

trade. Lead witnesses: Thomas M. Countryman, Assistant Secretary of State, Bureau of
International Security and Nonproliferation, and Daniel B. Poneman, Deputy Secretary of Energy.
