高通量工程试验堆异常事件数据库的建立与异常事件的统计和分析

Set up of Abnormal Events Database and Statistical Analysis of Abnormal Events for the HFETR

简要描述了高通量工程试验反应堆（ＨＦＥＴＲ）异常事件库的建立，重点对收集的异常事件进行了统计分析。结果表明，异常事件主要为反应堆控制和保护系统故障、反应堆冷却系统故障及其它故障。这三类故障占异常事件总数的８６．１％，但对安全无明显的影响。

the set up of abnormal events database for the High Flux Engineering Test Reactor(HFETR)is described,and its abnormal event are counted analyzed.The results show that the main abnormal events include reactor control and protection system breakdown.,reactor coolant system breakdown and others breakdown.These three breakdowns make up about 86.09% of the total events.But the influence of they or the reactor safety is not clear.
