Proryv Project. Equipment pre-commissioning is nearing completion at the innovative nitride fuel fabrication module in Seversk (Russia). Built under the Proryv (Russian for Breakthrough) project, the module is designed for the fabrication/re-fabrication of mixed uranium-plutonium nitride (MUPN) fuel and is part of an experimental power production facility (abbreviated ODEK in Russian). The fuel fabrication module consists mostly of carbothermal synthesis furnaces for sintering fuel pellets. ODEK includes three interconnected facilities: a MUPN fuel fabrication/re-fabrication module, a power unit with an innovative Generation IV fast neutron reactor BREST-OD-300, and an irradiated fuel reprocessing module. 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.
