摘　　要：反应堆压力容器(RPV)作为核电厂重要主设备之一,其完整性直接影响到核电厂的安全运行,为了确保反应堆压力容器的完整性,需要在设计、制造、安装和运行过程中重点关注相关问题。介绍了反应堆压力容器的材质发展过程、反应堆压力容器的典型降级模式,并对产生降级的原因进行了分析,提出了下一步预防降级可采取的措施,以确保反应堆压力容器的完整性,进而为核电厂的反应堆压力容器的设计、制造、安装和运行维护阶段提供参考。Nuclear reactor pressure vessel （RPV） is one of the critical equipments for a nuclear power plant, and it.s integrity will impact the safe operation of the nuclear power plant. To ensure the integrity of the reactor pressure vessel, safety concern is highlighted in design, manuidcture,installation and operation phase. It provided a reference for the nuclear power plant reactor pressure vessel in design,manufacture, installation,operation and maintenance phase by introducing the material development of reactor pressure vessel, typical degradation model of reactor pressure vessel, and analyzing reasons for the degradation and proposing relevant measures to ensure the integrity of RPV.
