Innovation. Rosatom has obtained an operation license for the world’s first production line for innovative mixed uranium-plutonium nitride (MUPN) fuel. The fuel fabrication and refabrication unit is the first facility of the experimental power plant (abbreviated ODEK in Russian) constructed as part of the Proryv (Breakthrough) Project. Other facilities under construction at ODEK include a Generation IV lead-cooled fast neutron reactor BREST-OD-300 and a reprocessing facility for irradiated fuel. When completed, ODEK will be the first ever nuclear power plant to integrate a fast neutron reactor and on-site facilities for closing the nuclear fuel cycle.
