摘要

The U.S. Department of Energy (DOE) National Nuclear Security Administration (NNSA) Office of Material Management and Minimization (M~3) has developed and is pursuing an integrated approach to address the persistent threat posed by unintentional proliferation of nuclear materials. The NNSA M~3 approach reduces the risk of highly enriched uranium (HEU) and plutonium falling into the hands of non-state actors by minimizing the use of and, when possible, eliminating weapons-usable nuclear material around the world. Consequently, the M~3 Reactor Conversion Program has sponsored efforts for decades to convert civilian research reactors from HEU to low-enriched uranium (LEU). This involves efforts to develop and qualify fuel, design and fabricate fuel elements, model fuel cycles and reactor operations, perform reactor safety analyses, maintain experimental performance and irradiation services, and support regulatory submissions that have successfully met the challenges of conversion for 71 reactors worldwide [1,2].As part of NNSA's ongoing HEU minimization mission, the M~3 Reactor Conversion Program is collaborating with six U.S. High Performance Research Reactors (USHPRR), including one critical facility, to convert from the use of HEU to LEU fuel. The work is being done through many inter-related activities that are being completed by stakeholders across organizations. The USHPRR Project work has been divided into four technical pillars led by several national laboratories to effectively manage the work scope. The Reactor Conversion (RC) Pillar (led by Argonne National Laboratory) performs, along with the facilities, all the necessary activities to convert the reactors such as fuel element design, reactor core safety analysis, licensing or other regulatory submittals and implementation. The Fuel Qualification (FQ) Pillar (led by Idaho National Laboratory) characterizes and documents the fuel performance and properties, and designs and executes the test and qualification irradiation campaigns. The Fuel Fabrication (FF) Pillar (led by Pacific Northwest National Laboratory) deploys viable industrial processes for the commercial production of LEU fuel elements for the six facilities under the scope of the USHPRR Project. The Cross-Cutting (CC) Pillar (led by Savannah River National Laboratory), addresses cross-pillar activities including, but not limited to, transport and back-end planning.
