Program for CNFC R&D using BN-800

Abstract

Abstract Beloyarsk NPP with BN-800 reactor provides unique opportunities for the further development of fast reactor (FR) technologies and the development of the closed nuclear fuel cycle (CNFC). R&D program on the development CNFC technologies on the basis of the BN- 800 are currently developed. Program is planned for both MOX and nitride fuel. The main purpose of R&D are optimization of CNFC technologies in industrial scale, getting the reference experience and testing technologies in BN-800, verification new generation computer codes. In the framework R&D program to simulate elements CNFC technologies is expected to make and demonstrate the three major step to CNFC – recycling of plutonium from spent fuel of thermal reactors; – multiple recycling of fuel fast reactors; – transmutation of minor actinides. The presented program includes three main blocks – the development of technologies for reprocessing spent MOX fuel of BN-800; – the development of technologies of mixed nitride fuel (forming BN-800 core with the insertion of the nitride fuel, the demonstration of recycle equilibrium fuel with breeding ratio ∼1); – development of partitioning and MA transmutation technologies in the FR. It is anticipated that this Program will create the world’s first industrial power complex in the fullness of implementing CNFC with FR in the 30s.
