一种避免RPN源量程闪发异常计数方法研究
|
摘要
某核电厂2号机组调试启动期间多次出现2RPN014MA闪发异常计数的问题,通过现场分段调查,对更换设备进行解体分析,同时结合多基地闪发现象,得出2RPN014MA闪发原因为外部干扰的引入。在此基础上研究增加RPN源量程核岛内电缆屏蔽,避免RPN源量程闪发异常计数方法,并在某核电厂机组上实施验证,取得良好效果,为后续核电机组RPN源量程安装及运维提供参考。
The problem of 2 RPN014 MA flashing anomaly counts occurred during the commissioning of Unit 2 of a nuclear power plant. Through the on-site segmentation investigation, the replacement equipment was disassembled and analyzed. At the same time, the multi-base flash was found and the 2 RPN014 MA flash was caused by external interference. Introduction. On this basis, we will increase the cable shielding in the RPN source range nuclear island to avoid the abnormal counting method of RPN source range flashing, and carry out verification on a nuclear power plant unit, which has achieved good results, and is the installation and operation and maintenance of the subsequent RPN source range of the nuclear power unit for reference.
