            Abstract:

             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.
