反应堆冷却剂放射性比活度运行限制条件研究
|
摘要
本文通过对比分析CPR1000和美国技术规格书中反应堆冷却剂放射性比活度运行限制条件(LCO)的制定原则和依据,结合蒸汽发生器传热管断裂事故(SGTR)放射性后果分析的验收准则和国标GB 6249的升版情况,研究我国CPR1000机组反应堆冷却剂放射性比活度运行控制要求中存在的问题,对美系技术规格书的应用进行了探讨,并提出了改进建议。
Through the comparative analysis of the limiting condition for operation of the radioactive specific activity of reactor coolant in technical specifications of domestic and abroad, the study is focused on acceptance criteria of SGTR radiation accident consequences,and the main changes of different versions of national standard GB 6249. The measures to control CPR1000 NPP reactor coolant radioactive specific activity under different operation modes and potential application of the United States NPP technical specifications were discussed and suggestions were proposed.
