【Abstract】 The neurtronics characteristics of minor actindes (MA) and fission products(FP) transmutation in spherical Tokamak fusion-fission hybrid reactor are calculated with BISON-C code.Some initial results which are valuable to blanket desing are given.This study shows that by verifying the loading amount of Pu,MA and FP in the blanket, the system subcritical degree can be adjusted and the transmutation rate can also reach high value duo to the hard neutron spectra.更多还原
