U.S. Department of Energy and the U.S. Navy Naval Nuclear Propulsion Program (NNPP) are planning to upgrade naval spent fuel handling facilities at the Idaho National Laboratory. The project, known as the Recapitalization of Infrastructure Supporting Naval Spent Nuclear Fuel Handling, is estimated to cost $1.6 billion. In October 2016 the NNPP released the final Environmental Impact Statement for the project (see also a brief summary).
