Russia’s state nuclear corporation Rosatom continues its successful research and development efforts to validate innovative nuclear fuels for next-generation fast neutron reactors. Two core designs with different types of uranium-plutonium nuclear fuel are being developed for the BN-1200 reactor: MOX fuel, and SNUP fuel. New SNUP and MOX fuel assemblies, produced at the Siberian Chemical Combine are scheduled for testing at the Beloyarsk NPP reactors. Core loading is planned for 2025. The BN-1200 is expected to become the world’s first serially produced fast neutron reactor. It represents the next evolutionary step in Russia’s sodium-cooled fast reactor line, following the BN-600 and BN-800 reactors at the Beloyarsk NPP. The BN-1200 will also be constructed at the Beloyarsk NPP site, with construction scheduled to begin in 2027.
