Sensitivity Analysis on Parameters of Spherical Model of Fusion-Fission Hybrid Energy Reactor

The sensitivity analysis on neutronics parameters related to neutron source, uranium-water ratio and tritium breeding layers for spherical blanket model of fusion-fission hybrid reactor were presented. By using a Monte-Carlo method based neutron transport code, the effects of the parameters on energy multiplication factor M and tritium breeding ratio TBR were analyzed, and the general various laws of M and TBR were summarized, which were significant for the further conceptual design of fusion-fission hybrid energy reactor.
