Congressional Research Service Report Released: Nuclear Energy: Overview of Congressional Issues
by Taryn Rucinski
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 in the reactor and can remain hazardous for thousands of
years. How to manage the weapons proliferation and safety risks of
nuclear power, or whether nuclear power is worth those risks, are issues
that have long been debated in Congress.
The
104 licensed nuclear power reactors at 65 sites in the United States
generate about 20% of the nation’s electricity. Five new reactors are
currently licensed for 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,
436 reactors are currently in service, and 62 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. The Commission recommended in January 2012 that
new candidate sites for nuclear waste storage and disposal facilities be
selected through a “consent based” process.
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.
