NPEC's Executive Director Signs Letter Urging Department of Energy to Defer Plutonium's Commercial Use

14 former senior energy and national security officials sign a letter to Department of Energy (DOE) Secretary Moniz to terminate a costly DOE plutonium fuel fabrication project (known as the mixed oxide or MOX program) designed to make plutonium–based fuels for US power reactors. The letter was featured in an article by Steven Mufson in The Washington Post, "Energy secretary is urged to end U.S. nuclear fuel program at Savannah River."

Many of the points highlighted in the letter and article were discussed in an earlier proposal by NPEC, A Mutually Beneficial Policy on Plutonium Fuels.

The Honorable Ernest J. Moniz
Secretary of Energy
U.S. Department of Energy
1000 Independence Avenue, S.W.
Washington, DC 20585-1000

Dear Secretary Moniz,

We write regarding the Department of Energy's (DOE's) “Red Team” report conclusion that the department can greatly reduce cost and risk by blending its excess weapons plutonium down for disposal as waste instead of continuing down the mixed oxide (MOX) fuel path. Many of us have come to similar conclusions in the past.

As outside nuclear experts and former government officials dealing with nonproliferation issues, we have looked at the matter closely. DOE can uphold its obligation to safely dispose of this material without implementing the MOX program. More important, in addition to saving money, ending the current MOX program would be in the nation’s national security interest.

Continuing with the MOX program and recycling work helps plutonium recycling advocates in Japan, China, South Korea, and other states maintain the illusion that plutonium separation and recycle are activities that responsible non-weapon states engage in. The United States has for four decades consistently opposed the spread of such activities because of the obvious proliferation danger of putting nuclear-weapons explosive materials into commercial channels.

It would be particularly advantageous to U.S. nonproliferation objectives to end the MOX program now. Japan is on the verge of opening its large reprocessing plant at Rokkasho. Ending the U.S. MOX program and thereby underlining that plutonium has no economic value would put the U.S. in a much better position to urge Japan to put off any such decision.

More broadly, there is an opportunity to ask not only Japan, but South Korea and China to join in a decision to defer commercial plutonium-based fuel activities (to include commercial "demonstrator" sized projects). None of these activities make economic sense. A simultaneous announcement would help these governments deal with their plutonium recycling interest groups. Indeed, we believe that such an announcement at the upcoming Nuclear Security Summit next spring would constitute a historic step to strengthen the nonproliferation regime.
