Breakthrough for Russian closed fuel cycle project

摘要

Russia has announced two new milestones in its Proryv or Breakthrough project to enable a closed nuclear fuel cycle. Siberian Chemical Combine (SCC) has completed testing of the first full-scale TVS-4 fuel assembly containing nitride fuel. The assembly is intended for the BN-600 fast neutron reactor, which is the third unit of the Beloyarsk nuclear power plant. Vladimir Troyanov, chief production engineer of the Breakthrough project, said the materials used for the TVS-4 fuel assembly possessed higher radiation stability, which "permits a substantial increase in its service life and, in turn, the efficiency of fast neutron reactors".
