Author information:

Lindsay Krall is a post-doctoral Macarthur fellow at the George Washington University Institute for International Science and Technology Policy. Her research focuses on policies for the back end of the nuclear fuel cycle, particularly as they pertain to radionuclide transport in the environment, systems and organizations for waste storage and disposal, and the long-term behavior of spent fuels from advanced reactors. Allison Macfarlane is Professor of Public Policy and International Affairs at the George Washington University’s Elliott School of International Affairs. She directs the school’s Institute for International Science and Technology Policy Program and is the former chairman of the US Nuclear Regulatory Commission. Macfarlane was a member of the Blue Ribbon Commission on America’s Nuclear Future from 2010-2012.


Nuclear energy-producing nations are almost universally experiencing delays in the commissioning of the geologic repositories needed for the long-term isolation of spent fuel and other high-level wastes from the human environment. Despite these problems, expert panels have repeatedly determined that geologic disposal is necessary, regardless of whether advanced reactors to support a “closed” nuclear fuel cycle become available. Still, advanced reactor developers are receiving substantial funding on the pretense that extraordinary waste management benefits can be reaped through adoption of these technologies. Here, the authors describe why molten salt reactors and sodium-cooled fast reactors – due to the unusual chemical compositions of their fuels – will actually exacerbate spent fuel storage and disposal issues. Before these reactors are licensed, policymakers must determine the implications of metal- and salt-based fuels vis a vis the Nuclear Waste Policy Act and the Continued Storage Rule.” end quote.Emphasis added for clarity. Mr. O’Brien and Mr. Bernardi need to consider the scientific and technical reality behind the gloss they want to disseminate.
