The Transient Reactor Test (TREAT) Facility Low-Enriched Uranium (LEU) Fuel Conversion Project proposes to develop and qualify LEU fuel for the TREAT reactor. The TREAT reactor conversion project is managed by National Nuclear Security Administration's (NNSA's) Office of Materials Management and Minimization (MMM) that works to develop and qualify new fuels and technologies to support conversion efforts domestically and abroad. In instances where suitable LEU fuels do not exist for particular reactors to convert, the Convert Program contributes to the development of new LEU fuels. As no suitable LEU fuel is currently available with which the TREAT reactor could convert, the proposed action is to research and develop a new LEU fuel and fabrication capability to allow for conversion. The proposed action uses existing facilities at the Idaho National Laboratory's (INL's) Materials and Fuels Complex (MFC) and TREAT to support research and development (R&D) activities in support of LEU fuel development for the TREAT reactor.
