摘要
柴油发电机组作为反应堆安全系统,柴油机作为备用电源在发生失电事故时系统启动运行为反应堆设备提供可靠的控制、动力电源保证反应堆安全停堆。冷却水系统作为柴油发电机系统重要组成部分,在系统运行时为系统提供冷源,保证机组安全稳定运行,在机组备用期间起到预热作用,保障机组处于随时可用状态。冷却水系统故障会造成机组启动困难、运行不稳定,影响反应堆的安全。本文通过对冷却水系统原理及设备功能进行分析,给出相应问题处理方案并实施,消除了冷却水系统故障,恢复了机组功能,为反应堆安全稳定运行提供了有力保障。
The diesel generator set is used as the reactor safety system and the diesel engine is used as the standby power supply.In case of power loss accident,the system starts and operates to provide reliable control and power supply for the reactor equipment and ensure the safe shutdown of the reactor.As an important part of the diesel generator system,the cooling water system provides a cold source for the system during system operation,ensures the safe and stable operation of the unit,plays a preheating role during the standby period of the unit,and ensures that the unit is available at any time.The failure of cooling water system will lead to difficult startup and unstable operation of the unit,and affect the safety of the reactor.This paper analyzes the principle and equipment function of the cooling water system,gives the corresponding problem treatment scheme and implements it,eliminates the failure of the cooling water system,restores the unit function,and provides a strong guarantee for the safe and stable operation of the reactor.
