Abstract

Role of fast reactors in the problem of lowering of minor actinides (MA) quantity in the fuel cycle of nuclear power is considered in the report. The requirement to MA quantity in closed fuel cycle is formed. The results of analysis of BN-800 reactor possibilities for MA quantity reduction at PO MAYAK are discussed in the report. The recommendations are given on choice of actinide extraction coefficient values during the chemical reprocessing of spent fuel. The coefficients are the following: for Pu and Am - 0.9998, for Np and Cm -0.98.
