| 摘 要： | 运用蒙特卡洛程序MCNPX以及欧洲活化计算程序FISPACT-2007,分析了中国聚变工程实验堆(CFETR)满功率运行时产氚包层各分区的核热功率,计算了满功率运行时产氚包层在高能中子的照射下活化产物的放射性活度、典型栅元的停堆剂量率.计算结果表明,当CFETR在满功率运行一年后停堆,停堆时的包层总活度为6.61×1019Bq,停堆十年后总活度降为7.98×1018Bq,为刚停堆时总活度的12.1%.结果显示,CFETR包层设计不存在突出的安全问题.

| Abstract: | Using Monte Carlo code MCNPX and the activation calculation code FISPACT-2007, nuclear heat, radioactivity and shutdown dose rate for China fusion engineering test reactor (CFETR) were calculated. The calculation results show that the total radioactivity is 2.34×1019Bq at shutdown after one year operation and the total radioactivity is 7.98×1018Bq after ten years which is 12.1% of the original radioactivity. The results show that there isn't serious environmental issue. |
