使用数值方法并通过程序的改进完善,在高通量工程试验堆(HFETR)某炉次装载方案的基础上进行不同工况下的氙毒效应计算研究,得到HFETR以不同功率运行相同积分功率、以不同功率运行不同积分功率后紧急停堆的氙毒效应曲线。结果表明理论计算与HFETR实际运行工况相符,对HFETR安全运行具有指导意义,本文计算研究结果已成功应用到HFETR实际运行中。 Using numerical method and through the improvement of the program, we calculated the xenon poisoning effect under different operating conditions on the basis of a furnace loading program of HFETR, and got the HFETR to run the same integrated power with different power, Xenon toxic effect curve of emergency shutdown after running different integral power with different power. The results show that the theoretical calculation is consistent with the actual operating conditions of HFETR, which is instructive for the safe operation of HFETR. The results of this study have been successfully applied to the actual operation of HFETR.
