| 摘 要： | 通过实时测量反应堆主冷却剂中关键核素131I、137Cs的活度来进行压水堆燃料元件破损监测时，主要的影响因素有净化系统的净化效果、核素自身的衰变、活化产物的影响、能量相近的裂变产物等。对这些影响因素进行了分析、推导，结果表明，只有裂变产物99Mo对131I的定量测量有较大影响。

| Abstract: | Purification-efficiency of the coolant purification system, decay of the key nuclides, effect of the activation products, effect of the energy-adjacent fission products, etc. are the main influencing factors in the fuel element rupture detecting by measuring the activity of the key nuclides in the primary coolant. These factors were calculated and analyzed systematically, and the results indicate that 99Mo has a prominent effect on the activity measuring of the key nuclides. |
