Abstract

The effective implementation of a two-component nuclear power system depends on the development of basic reactor technologies VVER and BN, their interaction in a closed nuclear fuel cycle. Possession of closed nuclear fuel cycle technologies determines not only the prospects for solving the accumulated problems of Russia's nuclear energy, but also the potential to strengthen positions in the global market of fuel cycle services.
Using a complex approach to the simultaneous calculation of neutron-physical processes during irradiation of fuel in the reactor and the processes of molecular selective transfer of components in the separation cascade during the enrichment of regenerated uranium, a simulation of the scenario for the provision of closed fuel cycle services in the foreign market was carried out.
For a model scenario of plutonium exchange between two WWER and one high-power BN reactor, a comparison of the characteristics of the WWER fuel cycle (the expenditures of natural uranium, the expenditures of separation work in the manufacturing of REMIX fuel for WWER from a mixture of plutonium dioxide and enriched regenerated uranium) was carried out. Options are considered when in light-water reactors own plutonium from WWER spent fuel are recycled together with enriched regenerated uranium and when plutonium is exchanged with a fast reactor in the same quantities.
