摘要:

水冷陶瓷包层是中国聚变工程实验堆(CFETR)的三种候选包层概念之一。基于CFETR水冷陶瓷包层的一维中子学模型,通过蒙特卡罗输运模拟程序MCNP和活化计算程序FISPACT的耦合计算,经三维转换系数修正,分析了CFETR水冷陶瓷包层时间相关产氚特性。结果表明,当CFETR运行因子为0.5,聚变功率为200MW时,水冷陶瓷包层在运行5年、10年、20年后,氚增殖率(TBR)的降低都不显著,但是年产氚剩余量的降低很明显。此外,产氚包层内初始时刻TBR对产氚特性的影响也很大。

Abstract:

Water cooled ceramic breeder blanket (WCCB) is one of the three blanket candidates for Chinese Fusion Engineering Testing Reactor (CFETR). Using a 1-D neutronics model of WCCB for CFETR and correction factor for simplification of neutronic model, time dependent tritium breeding characteristics of blanket were assessed by coupling calculation of the Monte Carlo neutron transport code MCNP and the inventory code FISPACT. Results showed that reduction of tritium breeding ratio (TBR) after several years, even to 20 years, was not obvious when duty time factor of CFETR is 0.5 and fusion power is 200MW, while reduction of annual tritium breeding production was distinct. Additionally, initial TBR of blanket has a great influence on time dependent tritium breeding characteristics.

Key words: WCCB, MCNP, FISAPCT, TBR, Tritium production
