摘要
在进行核电机组反应堆停堆保护系统定期试验时,需依次将停堆断路器实体断开,此类定期试验风险较大,国内外运行的核电机组多次发生在反应堆停堆保护系统定期试验过程中由于设备故障导致非计划停堆的事件,造成了较大的经济损失。论文介绍了某WWER核电机组反应堆停堆保护系统设计优化方案及改造的实践成果。
When carrying out periodic test of nuclear power unit reactor trip protection system,it is necessary to disconnect trip breakers in turn.There are big risks in such kind of periodic tests and many unplanned trip events happened because of malfunction of equipment in reactor trip protection system periodic tests of foreign and domestic nuclear power units under operation,which caused great economic loss.The paper introduces the practical results of design optimization and modification of reactor trip protection system of a nuclear power unit of WWER.
