摘要
针对核电厂反应堆核仪表系统(RPN)源量程通道闪发异常计数,甚至触发停堆等严重制约机组上行的问题,研究闪发成因,给出针对性的改进措施。本文以中国广核集团B核电项目2、3号机组为依托项目,将提炼的良好实践在安装阶段予以实施,经调试启动至商业运行的长期验证,该机组完全未出现任何因RPN源量程闪发异常计数而影响机组上行的重大问题。
Considering the abnormal spike of source count for RPN system present on several units of various nuclear projects of China General Nuclear Power Group, even causing the trip of the unit, it is considered as the very serious issue for the power increasing of the unit. In order to avoid this phenomenon, a professional site team is built to do the investigation and propose the modification. Taking units 2 and 3 of project B as examples in this paper, good experiences are implemented in the erection. Long time operation from commissioning, start-up and commercial operation verified that no abnormal spike count is observed.
