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0.78 MW/m2、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0.017 5 g/d、最大功率密度9.27MW/m2及总功率沉积0.422 MW/m3。
Three-dimensional neutronics calculations were performed on the tritium multiplication module (TBM) of a Chinese helium-cooled solid proliferation agent (HCSB) with a 3 × 3 sub-module structure using the three-dimensional neutron program MCNP and the FENDL2.0 database. The calculation conditions are: wall load factor is 0.78 MW / m2, operating factor is 22%. The calculated TBR tritium multiplication ratio (TBR) was 0.907, the total tritium production rate was 0.017 5 g / d, the maximum power density was 9.27 MW / m2 and the total power deposition was 0.422 MW / m3.
