给出了高通量工程试验反应堆(HFETR)中主要的七种同位素活性计算方法及计算公式,考虑了堆芯中子注量率场中放入一靶件后,靶件对中子注量率的扰动,给出了目前使用的七种同位素靶件在HFETR中的扰动因子。考虑靶件扰动后的同位素靶件活性计算结果较改进前精度提高了10％以上。该工作结束了HFETR堆芯同位素生产除~(60)Co外的活度
The calculation methods and calculation formulas of the seven main isotope activity in HFETR are given. After putting a target into the neutron flux field of the core, Rate perturbation, and gives the perturbation factors of the seven kinds of isotope target currently used in HFETR. The calculated results of isotope target activity after perturbation of the target have improved by more than 10% compared with that before the improvement. This work ended the activity of HFETR core isotope production except ~ (60) Co
