压水堆核电站反应堆保护系统投运与退出方案论述

摘要

During every fuel cycle, the unit of nuclear power plant need back up for maintenance and fuel replacing. And then up and running again. In this phase, the reactor protect system need run and stop. The article discusses the scheme of run and stop of reactor protect system in one pressurized water reactor.%核电厂每个换料周期,机组需要下行进行换料和大修,结束后再重新上行至正常运行,这期间反应堆保护系统需要投运和退出.本文结合某压水堆核电站反应堆保护系统的设计原理和实现方式,介绍了压水堆核电站反应堆保护系统投运与退出的方案.
