核电厂设备冷却水系统温度控制方式改造与实践

Transform and practice of temperature control mode for equipment cooling water system in nuclear power plant

核电厂设备冷却水系统在冬季时水温偏低,不能满足核电机组部分设备运行的要求,针对此问题实施改造。介绍了相应的改造方法,改造实施内容、过程,以及控制部分现场实施的经验反馈。增加的控制回路实施可控、操作方便,系统投运后最终取得了较好的效果,可为其他电厂实施相同改造提供借鉴。

The equipment cooling water temperature is low in winter,which cannot meet the operation requirements of some equipments of nuclear power plant,and transform it.This article introduces the transformation method,content,process,and the control part on-site implementation experience feedbacks.The added control loop is controllable and easy to operate.Finally,the system is put into operation,and better results are achieved,which provides a reference for other power plants.
