| 摘 要： | 在高通量工程试验堆（HFETR）中，3He回路内气体压力变化会向反应堆引入反应性，进而影响到HFETR的运行安全。本文利用蒙特卡罗（MCNP）程序计算了3He辐照考验装置反应性变化速率，并利用RELAP5程序对3He屏失压与HFETR 1根控制棒失控提出叠加事故进行了分析。结果表明，正常工况下，3He回路辐照试验不影响HFETR 正常运行；3He屏失压事故与HFETR事故工况叠加不会影响HFETR安全。

Analysis of Reactivity Introducing Accident in ~3He Irradiation Rig |

| Abstract: | In the high flux engineering test reactor (HFETR), the change of gas pressure in 3He loop would introduce reactivity to the reactor, and then affect the operation safety of the reactor. The reactivity change of the variable power rig was calculated by MCNP code in this paper, and the superimposed accidents of the loss of pressure in 3He tube and the withdrawing of the control rods were analyzed by RELAP5 code. The results showed the irradiation tests conducted in rig do not have effects on the normal operation of HFETR. Even when the loss of pressure in 3He tube and the withdrawing of the control rod happened at the same time, the safety of HFETR was guaranteed. |
