Overview of the US Fast Reactor Technology Programme

This paper provides an overview of fast reactor research and development (R&D) efforts in the United States of America. The diverse R&D activities are funded by several programmes in the US Department of Energy’s nuclear energy portfolio. Innovative technology options that may yield significant cost reduction benefits have been identified through concept development studies: high strength structural materials, a supercritical CO₂ Brayton energy conversion cycle, and advanced modelling and simulation techniques. In addition, technology development efforts for safety and licensing, improved recycle fuels, and under-sodium viewing are ongoing. For each area, recent accomplishments and key facilities are identified to provide an indication of current status. (author)
