摘要
针对某核电厂因主蒸汽热辐射和夏季天气炎热而造成的主蒸汽隔离阀及其执行机构所在房间温度长期偏高的问题,提出了通风系统改造方案,并完成了改造项目。改造后房间温度显著下降,设备可靠性有效提高。
For the continual high temperature problem in the rooms of main steam isolation valve and its actuator in a nuclear power plant caused by thermal radiation of the main steam and hot summer weather, proposes a ventilation system reformation scheme and completes the reformation project. The results show that the room temperature significantly decreases and the reliability of the equipment effectively improves.
