摘要
介绍了田湾核电厂安全仪控系统(TXS系统)失效概率的估算方法,推导了用于反应堆停堆系统和ESFAS系统失效概率估算的一般性公式。并以主给水/主蒸汽系统故障停堆和触发应急给水系统启动两个仪控功能为例进行计算,结果证明田核电站TXS系统失效概率满足可靠性要求。
This paper describes the estimation of failure rate for TXS system in Tianwan NPP, induces some usual formulas for estimation of failure rate of reactor trip system and ESFAS system. According to the result of the calculation of failure rate of AA14 （Reactor trip because of the failure in main water/main steam system） and BBll（actuation of emergency water system） , the result proves that the reliability of TXS system in Tianwan NPP satisfies the requirement.
