Calculations of the 3-D neutronics for CH HCSB TBM with 3×3 sub-modules

摘要

Using three dimension MCNP code and FENDL2.0 data library, neutronics calculation for a HCSB (helium cooling solid breeder) TBM (test blanket module) with 3×3 sub-modules has been performed. Local tritium breeding ratio (TBR) of 0.907, total tritium generation rate of 0.0175g·d-1, peak power density of 9.27MW·m-3 and total power deposit of 0.422MW·m-3 are obtained under neutron wall loading of 0.78MW·m-2 and duty factor of 22%.
