百万千瓦核电机组常规岛闭式冷却水系统大修期间停运窗口分析

Outage Window Analysis of Conventional Island Closed Cooling Water System of 1000 MW Nuclear Power Plant During Overhaul

核电机组大修期间常规岛闭式冷却水系统(SRI)的停运时机对常规岛检修工作的开展有关键影响。文章通过研究冷却水的热负荷及作用,对SRI的停运窗口进行了理论分析。提出了停运的最佳时机,对大修工作的开展和降本增效有积极的借鉴意义。

The outage time of the conventional island closed cooling water system(SRI) during the overhaul of nuclear power plant has a key impact on the maintenance of the conventional island. By studying the heat load and function of the cooling water, this paper theoretically analyzes the shutdown window of SRI. The best time of shutdown is put forward, which has positive reference significance for the development of overhaul work, cost reduction and efficiency improvement.
