Abstract:

The neutronics problem of the TBM module design connects closely with TBM’s other problems, such as, tritium generation, thermo-hydraulic, safety, etc. An exact neutronics calculation for the TBM module is very important. Based on the 1-D calculation model given in the CH HCSB TBM design, a better 1-D neutronics optimization has been performed using the ONEDANT code with related database.

摘要：

ITER 实验包层模块（TBM）的中子学问题与系统的氚增殖、热工水力、安全等问题密切相关，因此TBM的中子学优化设计极为重要。在CH HCSB TBM 设计描述报告的一维中子学计算模型的基础上，利用一维中子输运计算程序ONEDANT和配套的数据库，以功率密度和氚增殖比等参数为优化目标进行中子学优化设计，得到了更为合理的中子学设计方案。
