The activation of a neutron generator is modeled for two operating scenarios: continuous for 16 h and 100 h at 4 h/day for one month. The distribution of the equivalent γ-ray dose rate was calculated for different times after the generator was shut down. Different grades of steel were considered for the material of the neutron generator flange. The time dependence of the γ-ray dose rate was calculated for each variant of steel. For long holding times, the steel 316L(N)-IG exhibits the lowest dose rate.

快中子发生器结构材料的活化

中子发生器的激活是针对两种操作场景建模的：连续 16 小时和 100 小时，每天 4 小时，持续一个月。计算了发电机关闭后不同时间的等效γ射线剂量率分布。中子发生器法兰的材料考虑了不同等级的钢。计算了每种钢变体的 γ 射线剂量率的时间依赖性。对于长时间保持，钢 316L(N)-IG 表现出最低的剂量率。
