French-Style Nuclear Reprocessing Will Not Solve U.S. Nuclear Waste Problems

Institute for Energy and Environmental Research | Press Release

Contrary to some prevailing opinion, reprocessing would not eliminate the need for a deep geologic disposal program to replace Yucca Mountain. It aggravates waste, proliferation, and cost problems. The volume of waste to be disposed of in deep geologic repository is increased about six times on a life-cycle basis in the French approach compared to the once-through no-reprocessing approach of the United States.

A new report by the Institute for Energy and Environmental Research (IEER), a nonprofit scientific research group, shows that France uses less than 1 percent of the natural uranium resource, contrary to an impression among some policy makers. The report has several recommendations for President Obama’s Blue Ribbon Commission on America’s Nuclear Future, which was created to address U.S. nuclear waste issues after the administration’s cancellation of the Yucca Mountain program.

IEER President Dr. Arjun Makhijani, the author of the report: “In recent years, a ‘French fever’ has gripped the promoters of nuclear power in the United States. Praise of France’s management of spent fuel by reprocessing, including its use of the extracted plutonium as fuel in its nuclear power reactors, is now routinely heard. But it is a fantasy on the scale of the 1950s “too cheap to meter” mythology about nuclear power to imagine that 90 or 95 percent of the “energy value” of U.S. spent fuel can be extracted by reprocessing.”

Key IEER report findings include the following:

  --  On a life-cycle basis, French-style reprocessing and recycling increases
      the volume of waste that would have to be disposed of in a geologic
      repository. Reprocessing results in high-level radioactive waste and
      large volumes of Greater than Class C waste, both of which must be
      managed by deep geologic disposal. Their combined volume on a
      life-cycle basis is estimated to be about six times more than the
      no-reprocessing approach that is current U.S. policy, according to
      Department of Energy estimates. Low-level waste volume and waste
      transportation shipments are also estimated to increase several-fold.
  --  France spends about two cents per kilowatt-hour more for electricity
      generated from reprocessed plutonium compared to that generated from
      fresh uranium fuel.
  --  Attempting to combine reprocessing with breeder reactors to convert
      uranium in U.S. spent fuel in plutonium will create intolerable costs
      and risks. Reprocessing plus breeder reactors are much more expensive
      than light water reactors today, which are themselves expensive. Such
      a system is required to convert most of the uranium in spent fuel into
      a reactor fuel. Even a single penny in excess generation cost per
      kilowatt-hour in a breeder reactor-reprocessing system would lead to
      an added $8 trillion in costs to convert nearly all of the uranium in
      the 100,000 metric tons of U.S. spent into usable fuel. It would take
      hundreds of years to accomplish the task and require separation of
      tens of thousands of bombs equivalent of fissile material each year.
      The proliferation risks will be far greater than today.
  --  Adoption of a French-style reprocessing program would not eliminate the
      need for a deep geologic repository. Even complete fissioning of all
      actinides - an unrealistic proposition - will leave behind large
      amounts of very long-lived fission and activation products like
      iodine-129, cesium-135, and chlorine-36 that will pose risks far into
      the future -- much beyond the 24,100-year half-life of plutonium-239.
      In fact, France needs a geologic repository and opposition to one has
      been intense there. The French appear to dislike nuclear waste in
      their backyards as much as people in the United States.
  --  Proliferation risks are inherently part of the French (and any other)
      approach to reprocessing. Even advanced reprocessing technologies will
      not significantly reduce proliferation risks. For instance a study
      authored by scientists from DOE laboratories, including Los Alamos and
      Sandia, concluded that it would take only a few days or a few weeks
      for a proliferant country to make material for nuclear bombs once it had
      reprocessing plants. It found that new technologies, including
      electrometallurgical processing, resulted in "only a modest
      improvement in reducing proliferation risk over existing PUREX
      technologies and these modest improvements apply primarily for
      non-state actors." The IEER report concluded that electrometallurgical
      increases risks in other ways. For instance, it is far less difficult
      to conceal a plant than the present PUREX technology.

Other key findings include the following:

  --  Six decades of sodium cooled breeder reactor development has so far
      resulted in failure. Historical experience indicates no learning curve
      for the sodium cooled fast breeder reactor, which is the breeder
      technology that has received the most development. In fact, the two
      most recent large scale demonstration reactors, Superphénix in France
      and Monju in Japan, have been failures. Superphénix had a cumulative
      capacity factor of less than 8 percent before it was shut. Monju has
      been closed for almost 15 years, following a sodium fire, and has not
      generated a significant amount of electricity. Sodium cooled breeder
      reactors are not commercial today despite global expenditures on the
      order of $100 billion over six decades. They face a host of safety,
      proliferation and cost hurdles to overcome, some arising from the fact
      that they use liquid sodium for cooling. They are unlikely to be
      commercial in the near future. For instance, Japan's estimated date
      for commercialization of the sodium cooled fast breeder is 2050.
  --  Storage of liquid high-level wastes creates some risk of catastrophic
      releases of radioactivity. For instance, the Norwegian Radiation
      Protection Authority has estimated that a severe accident at the
      liquid waste storage facility in Sellafield, Britain, could result in
      cesium-137 contamination between 10 percent and 5,000 percent of that
      created in Norway by the 1986 Chernobyl nuclear reactor accident,
      which is the worst commercial accident to date, by far. A catastrophic
      release of radioactivity from a military high-level waste tank
      occurred in the Soviet Union in 1957.
  --  Using more than 1 percent of the uranium resource in a light water
      reactor system is technically impossible even with reprocessing and
      re-enrichment. In light water reactor systems, almost all the uranium
      resource winds up as depleted uranium or in spent fuel. Even with
      repeated reprocessing and re-enrichment, use of the natural uranium
      resource cannot be increased to more than 1 percent in such a system.
      A corollary is that the use of 90 to 95 percent of the uranium
      resource or of the material in the spent fuel is impossible in a light
      water reactor system even with reprocessing.

These are physical constraints that go with the system and also apply to France’s system.

The IEER report also sets out a number of recommendations for the Blue Ribbon Commission on America’s Nuclear Future appointed by Energy Secretary Steven Chu:

  --  Spent fuel from existing reactors should be slated for direct geologic
      disposal without reprocessing of any kind; a suitable path for a
      scientifically sound program should be set forth.
  --  In the interim, spent fuel should be stored on site as safely as
      possible - in low density configurations while in pools and in
      hardened storage when moved to dry casks.
  --  Breeder reactors and reprocessing are not commercial after six decades
      of development of sodium cooled breeder reactors, and enormous
      expenditures. Given the long time frame for commercialization
      estimated even by some promoters, the proliferation risks, and efforts
      already made, it does not appear to be a good investment to spend more
      R&D money in that direction. Rather energy supply R&D resources should
      be focused on development and deployment of renewable energy
      technologies and energy efficiency.
  --  The Commission should request the French company AREVA and/or the
      French government to supply it with data on the present use of the
      natural uranium resource purchased for French nuclear reactors,
      including, specifically, the increases in fission fraction that have
      actually been achieved by reprocessing and recycling.
  --  The Commission should also request official data on Greater than Class
      C waste equivalent expected to be generated on a life-cycle basis in
      France, and the total volumes and heat generation of packaged waste
      expected to be disposed of in a deep geologic repository, including
      estimates of decommissioning waste.
  --  The Commission should investigate the public support or lack thereof
      for repository programs in France and Britain, the countries with the
      longest history of commercial spent fuel reprocessing.
  --  The Commission should make the same requests regarding the British
      reprocessing program.
  --  Official analyses of the mechanisms, probability, and consequences of
      large accidental releases of radioactivity to the atmosphere from
      liquid high-level waste storage in tanks should be requested from the
      French and British governments.

ABOUT IEER

On March 24, 2010, IEER held a news conference to release documents acquired under the Freedom of Information Act (FOIA) showing that the outgoing Bush Administration inked 11th-hour agreements with more than a dozen utilities involving 21 proposed nuclear reactors. As IEER noted, between the output of existing commercial nuclear reactors and the 21 proposed nuclear reactors covered by the agreements quietly signed by the outgoing Bush Administration, the U.S. already has agreed to store enough spent (used) reactor fuel to fill the equivalent of not one, but two, Yucca Mountain high-level radioactive waste repositories.

The Institute for Energy and Environmental Research provides policy-makers, journalists, and the public with understandable and accurate scientific and technical information on energy and environmental issues. IEER’s aim is to bring scientific excellence to public policy issues in order to promote the democratization of science and a safer, healthier environment.
