January 2000
Key Facts
- In 1982, Congress charged the Energy Department with
building a disposal facility for used fuel from the nation’s
nuclear power plants and high-level waste from U.S. defense
programs. The law set a deadline for the federal government
to begin accepting used fuel. That deadline expired on Jan.
31, 1998.
- Despite its legal obligation to start taking used
nuclear fuel in January 1998 and three federal court rulings
reaffirming this duty, the Energy Department says it cannot
fulfill its responsibility.
- In December 1998, DOE published a preliminary assessment
of the proposed repository site at Yucca Mountain, Nev. The
agency concluded, "public health and the environment can be
protected," and announced that it expects to make a final
decision on the suitability of the site for an underground
disposal facility in 2001.
- Congress is expected to consider legislation this year
that would reform the Energy Department’s nuclear waste
program, providing early acceptance of used nuclear fuel at
a proposed repository at Yucca Mountain in 2007, contingent
upon Nuclear Regulatory Commission approval of its license
application. The bill also includes provisions for a
science-based radiation protection standard for Yucca
Mountain and a safe transportation network to move fuel to
the repository.
- The Nuclear Waste Policy Act of 1982 committed the
Energy Department to finding a deep geologic disposal site
to isolate fuel. But the law did not provide precise
direction about how to execute that plan. Without clear
guidance from Congress, the federal government will continue
to delay temporary storage and disposal of used nuclear fuel
scattered in 41 states at nuclear power plants, research
reactors and defense-related facilities.
- Used fuel from commercial nuclear power plants consists
of solid ceramic-coated uranium pellets protected in
zirconium alloy tubes called fuel rods. A typical nuclear
power plant produces about 20 metric tons of used fuel each
year. All the used fuel produced by the nuclear energy
industry during more than 45 years of operation (40,000
metric tons), if stacked end to end, would cover a football
field four yards deep.
- America’s electricity consumers already have committed
$16 billion to pay for a federal used fuel storage and
disposal program. Now, delays in taking used fuel are
forcing consumers to pay millions more to keep used fuel
stored at reactor sites owned by their local utilities.
- The Energy Department’s failure to start taking used
nuclear fuel from nuclear power plants has created a
potential $56 billion liability. The federal government’s
potential liability is based on unforeseen expenses at
short-term storage sites and damages for failing to honor
used fuel acceptance contracts. As the length of time
increases on the default, so do costs to consumers and the
potential liability to taxpayers.
Background and History
The Nuclear Waste Policy Act (NWPA) of 1982 and its 1987
amendments assigned the Energy Department the task of
developing and managing a program to begin accepting the
nation’s used nuclear fuel by January 1998.
The Energy Department has experience considerable
difficulty in implementing the 1982 law, and is years behind
schedule in developing a repository.
The Energy Department’s failure to honor this unconditional
commitment could jeopardize the future of America's 103
nuclear power plants, our largest source of emission-free
electricity. By the end of this year, at least 27 nuclear
units will exhaust on-site pool storage capacity for used
nuclear fuel and must consider other storage measures that may
prove costly to consumers.
Yucca Mountain has the best attributes for a repository,
based on preliminary screening of sites in Texas, Washington
and Nevada. So, in response to federal government delays and
escalating costs, Congress amended the Nuclear Waste Policy
Act in 1987 and selected Yucca Mountain as the only site for
scientific study. The 1987 law also authorized, but did not
require, DOE to develop an aboveground monitored retrievable
storage facility that would temporarily house used nuclear
fuel. DOE insists that it cannot take fuel because no facility
exists.
The 1997 court decision is one of several rulings that
place added pressure on DOE to begin fulfilling its used fuel
disposal commitment.
Four years ago, a coalition of state utility regulators,
attorneys general and nuclear industry executives from more
than 20 states filed suit to force DOE to take fuel. The U.S.
Court of Appeals in 1996 reaffirmed DOE’s statutory obligation
to begin accepting used fuel in 1998.
Following that ruling, federal courts have continued to
hold DOE accountable to its fuel acceptance deadline based on
various legal principles. Since Oct. 30, 1998, the U.S. Court
of Federal Claims ruled in three separate cases that DOE
breached its contract to begin used fuel acceptance, creating
a potential taxpayer liability of up to $56 billion.
On Nov. 30, 1998, the Supreme Court effectively left in
place DOE’s clear obligation to move used nuclear fuel
beginning in 1998. But the nation’s highest court also refused
to hear two appeals, one from public utility commissioners
seeking to force DOE to take waste and store it. The second
appeal sought to overturn a Federal Court of Claims ruling
allowing utilities to seek damages for DOE’s breach of
contract.
In addition to pursuing legal remedies, the industry has
sought to change the federal government’s policy of continued
delays by supporting reform legislation.
The Senate adopted the Nuclear Waste Policy Act of 1997 by
a 65-34 vote, and the House of Representatives passed similar
legislation by a 307-120 vote. But legislation abruptly
stalled in June of that year as election campaigns gained
momentum.
Legislation Needed To Speed Federal Movement of Used
Fuel
Senate Energy and Natural Resources Committee Chairman
Frank Murkowski said in January that the U.S. Senate is
expected to consider the Nuclear Waste Policy Act early this
year. The legislation (S. 1287) is a streamlined version of a
comprehensive bill considered in previous years, yet provides
clear direction for the Department of Energy to begin managing
used nuclear fuel and continue work at a proposed repository
at Yucca Mountain.
S. 1287 includes five principles supported by sponsors of
the bill and the nuclear energy industry:
- Accepting used nuclear fuel at Yucca Mountain as soon as
DOE receives a construction authorization for a repository
from the Nuclear Regulatory Commission, expected in 2007;
- Establishing a radiation protection standard for the
public near the repository that protects public health and
safety;
- Authorizing DOE to settle lawsuits filed by utilities
and take title for fuel at reactor sites where additional
on-site storage cannot be built, and giving priority to the
transportation of this fuel for early acceptance at Yucca
Mountain. In these settlements, use of the Nuclear Waste
Fund to pay damages to utilities would be prohibited.
- Requiring approval by a joint resolution of Congress for
proposed adjustments by DOE of the Nuclear Waste Fund fee;
and
- Providing special considerations for state and local
government for routing of used nuclear fuel shipments. State
and local governments also would receive funding for
training transportation personnel and emergency responders.
Passage of S. 1287 is an essential step forward for the
nation’s program to safely manage used nuclear fuel. Today,
used fuel is stored at nuclear power plant sites in 34 states,
either in steel-lined, water-filled concrete vaults or in
above-ground steel or steel-reinforced concrete storage
containers. However, these interim measures were never
intended to serve long-term storage needs. Similarly,
high-level radioactive waste from research reactors and
defense-related activities being stored across the country
must be disposed of at a federal repository.
Scientific organizations worldwide have examined the issue
of used nuclear fuel disposal, and virtually all support the
same conclusion: management of fuel is safest when disposed of
at an underground repository. S. 1287 provides a clear path
toward this goal, while meeting the federal government’s
responsibility to begin managing used fuel, which was to begin
in 1998.
Used Nuclear Fuel: Small Volume, Safe Storage
The proposed repository at Yucca Mountain today is like a
large laboratory complex, where world-class scientists conduct
scores of experiments to determine the site’s suitability for
long-term disposal of used nuclear fuel. If a repository is
built in the Nevada desert, fuel would be handled and packaged
at a surface facility and delivered through ramps to a mine
1,000 feet underground—and 1,000 feet above the water
table—where it would be preserved in sealed containers. A
series of man-made and natural barriers would further protect
the environment.
The used fuel to be stored there would come from nuclear
plants powered by uranium oxide fuel, research reactors and
defense-related activities. More than 100 nuclear reactors
produce about 2,000 metric tons of used fuel annually.
This fuel, in the form of thimble-sized ceramic pellets, is
placed inside metal fuel rods, which are grouped into bundles,
called fuel assemblies
About every 18 to 24 months, a reactor is shut down and the
oldest fuel assemblies—which have released most of their
energy but have become radioactive as a result of fission—are
removed and replaced. Fission—the splitting of uranium atoms
in a chain reaction—produces heat energy that boils water into
steam and drives a turbine-generator to produce
electricity.
Ultimately, this used fuel must be responsibly stored for
the long term in an underground repository. The Energy
Department also must store more than 22,000 high-level
radioactive waste containers and 2,750 metric tons of spent
fuel produced for national security activities.

Scientific Studies Will Determine Yucca Mountain
Suitability
Site characterization at Yucca Mountain is one of the most
thorough and comprehensive scientific investigations ever
conducted. When completed next year, site characterization
will have lasted 15 years, cost more than $6 billion and
involved more than 2,000 scientists, engineers and
technicians.
The studies focus on all aspects of the Yucca Mountain site
that will play a role in isolating used nuclear fuel. In
particular, the research examines three key subjects:
earthquakes, volcanoes and the movement of water through
layers of rock at the site. Much of that study centers on
better understanding the natural barriers that will work with
engineered systems to provide long-term isolation of nuclear
fuel. Engineers also are researching what container materials
are most compatible with the geochemical properties of Yucca
Mountain and how to prolong the container life if it should
come in contact with water and be exposed to changing thermal
conditions.
Safely Transporting Used Nuclear Fuel
In addition to the storage and permanent repository
components of an integrated used fuel management program, the
federal government must develop a system for the safe
transportation of used nuclear fuel.
Used fuel will be delivered to storage and disposal
facilities by rail or truck.
Containers used for shipping reactor fuel typically have
stainless steel walls several inches thick, with radiation
shielding materials sandwiched between outer and inner metal
shells. Those designed for truck transportation weigh 25 tons
and carry one to seven used fuel assemblies. Railroad
containers weigh 75 tons to 125 tons, and carry 36 or more
assemblies.
To ensure that transportation containers retain their
integrity in the event of an accident, each container must
meet rigorous design requirements. The container designs must
be able to withstand the following tests in sequence:
- a 30-foot fall onto a flat, unyielding surface;
- a puncture test allowing the container to fall 40-inches
onto a steel rod six-inches wide;
- exposure to a fire of 1,475-degree Fahrenheit that
engulfs the whole container for 30 minutes; and
- a separate test requires containers to be submerged in
50 feet of water for eight hours.
Since 1964, the Transportation Department and the Nuclear
Regulatory Commission have ensured the safe transportation of
nearly 3,000 shipments of commercial used fuel. During that
time, more than 10,000 used fuel assemblies have traveled more
than 1.6 million miles in the United States. Although there
have been eight accidents involving commercial used fuel since
1964, no harmful levels of radioactivity have been
released.
Used nuclear fuel can be shipped only along specific
highway routes. The small, select corps of shippers must
comply with specific DOT and NRC regulations regarding the
transfer of used nuclear fuel.
Shippers must file a written route plan with the NRC, which
includes the origin and destination of the shipment, the
route, planned stops, estimated arrival times at each stop and
emergency telephone numbers in each state the shipment will
cross. DOT also requires the shipper to notify the governor of
any state through which the material travels.
States may participate in the routing selection process and
designate alternate routes. In either case, routes that avoid
highly populated areas are preferred.
