Abstract
Most of the PWRs in China have changed or plan to change their cycle length to 18 month,but a longer fuel cycle(like 24 month) is the trend in the future.Taking the Qinshan Phase II nuclear power plant as a research target,this paper designs two types of fuel management strategies with 56 and 60 fresh assemblies.And the enrichment of the fresh fuel assemblies increases to 4.95%..Through the optimization of the assembly and poison locations,both strategies meet the demand of 24 month cycle length,and all are good at economics and safety
