Russia’s next-gen liquid metal nuclear fuel assembly to push fast reactor boundaries
SMRTR summary
Russia's Rosatom has created a new nuclear fuel assembly (OS-5) with mixed nitride uranium-plutonium fuel and a liquid metal sublayer for fast neutron reactors. This design reduces fuel operating temperatures and thermal expansion, protecting the cladding. Developed for the BREST-OD-300 reactor in the "Proryv" project, it supports a closed nuclear fuel cycle with reprocessed fuel. The aim is to double burnup depth to 12%, extending fuel cycles and reducing waste per energy unit.
