The Department of Energy (DOE) proposes under the Global Nuclear Energy Partnership (GNEP) to build facilities to begin recycling the nation’s commercial spent nuclear fuel. GNEP’s objectives include reducing radioactive waste disposed of in a geologic repository and mitigating the nuclear proliferation risks of existing recycling technologies. DOE originally planned a small engineering-scale demonstration of advanced recycling technologies being developed by DOE national laboratories. While DOE has not ruled out this approach, the current GNEP strategic plan favors working with industry to demonstrate the latest commercially available technology in full-scale facilities and to do so in a way that will attract industry investment. DOE has funded four industry groups to prepare proposals for full-scale facilities. DOE officials expect the Secretary of Energy to decide on an approach to GNEP by the end of 2008. GAO evaluated the extent to which DOE would address GNEP’s objectives under (1) its original engineering scale approach and (2) the accelerated approach to building full-scale facilities. GAO analyzed DOE plans and industry proposals and interviewed DOE and industry officials concerning the pros and cons of both approaches.
