核反应堆故障早期检测和在线状态监测方法

即将颁布的核行业标准《核电厂反应堆堆内构件的振动监测》(简称标准)对早期监测反应堆压力容器堆内构件蜕化的方法、故障检测仪表和监测程序提出了要求，适用于以中子波动信号和反应堆压力容器振动信号为基础的堆内构件和一回路部件的动态特性的监测。本文强调了标准所包含的核电站新型仪表控制系统的监测方法。新系统不同于传统的监测系统，它的主要目的是早期故障检测．以便向电厂操纵员和检查维修人员提供有用的状态信息。

A Method for Early Failure Detection and Monitoring of On-line Condition of Nuclear Reactor

Monitoring of Vibration of Reactor Internal Structures in Nuclear Power Plant(referred to as the standard hereafter), which will be issued by nuclear industry, concludes a new methods for a new type of nuclear power plant instrumentation and control system. This new system differs from the traditional monitoring systems, as it aims primarily at early failure detection. Useful information is provided to plant operators, but in particular to the inspection/maintenance personnel. The standard is used as an example for early failure detection and on-line condition monitoring methods based on signature analysis and feature vector monitoring in general.
