| 摘 要： | 从不同的角度分析了正常工况和事故工况下核电厂主控室进风γ辐射水平报警阈值方案。采用MCNP程序模拟测量点的γ剂量率,针对两种布置方案,对S3、DBA-LOCA和LOCA 3类典型事故进行了计算。结果表明,改进后主控室内的探测器报警阈值维持原报警阈值是合适的。

| Abstract: | The intake air gamma radiation monitoring alarm threshold of nuclear plant main control room was studied for both normal and accidental conditions . For two different layout schemes ,gamma radiation dose rates of measuring points was calculated with the MCNP code for three typical accidents including S 3 ,DBA-LOCA and LOCA .The results show that it is proper to keep original value of the detector alarm threshold for the main control room after improvement ,which could provide effective radiation protection for indoor staff . |
