岭澳核电站一回路抽真空排气方法研究与应用

Research and Application of Vacuum Exhaust Method in Primary Loop of Ling'ao Nuclear Power Plant

采用压水堆核电机组一回路抽真空排气方法,对岭澳核电站换料大修后反应堆一回路进行抽真空排气操作,取消了原有动态排气过程。结果表明,一回路空气含量很快满足要求,缩短了大修工期,提高了电站经济性和安全性。

This paper adopts the method of vacuum exhaust in the primary loop of PWR nuclear power unit. Primary loop of PWR Ling＇ao Nuclear Power Plant is vacuum exhausted after refueling overhaul, and the dynamic exhaust process is cancelled. The results show that the requirements of the air content of the primary circuit can be satisfied quickly, shortening the overhaul schedule, and improving the economy and safety of the power station.
