Neutronics Analysis and Optimization for Fusion Driven Subcritical Spent Fuel Burning System

Neutronics analysis and optimization including general performances, burnup calculation analysis, materials activation characteristic and irradiation damage analysis of blanket for fusion driven subcritical spent fuel burner (FDS-SFB) were performed. The results showed the fission blanket could reach high performance in a long burn up when the mass percent of transuranic nuclides reach to 15 %, depleted uranium added to the blanket could improve the ability of nuclear waste incineration and fuel breeding and FDS-SFB is able to achieve efficient utilization of nuclear waste to produce energy without additional new nuclear waste production.
