具有3×3子模块结构的中国HCSBTBM的三维中子学计算

Calculations of 3-D Neutronics for China HCSB TBM Module with 3 × 3 Sub-modules

摘要: 采用三维中子学程序MCNP及FENDL2．0数据库，对具有3×3子模块结构的中国氦冷固体增殖剂（HCSB）的氚增殖包层模块（TBM）进行了三维中子学计算。计算条件是：壁负载因子是0．78MW／m^2、运行因子是22％。计算得到的TBM氚增殖比（TBR）是 0.907、总氚产生率是0．0175g／d、最大功率密度9．27MW／m^2及总功率沉积0．422MW／m^3。By using three-dimension MCNP code and FENDL2.0 data library, the neutronics calculation for a HCSB （Helium Cooling Solid Breeder） TBM （Test Blanket Module） with 3 × 3 sub-modules has been performed. Under neutron wall loading of 0.78 MW/m^2 and duty factor of 22%, it is given for the tritium breeding ratio （TBR） of 0. 907, total tritium generation rate of 0.0175 g/d, peak power density of 9.27 MW/m^3 and total power deposiit of 0.422MW/m^3.
