Abstract
The conventional island ventilation system of a nuclear power plant has complicated types, numerous valves, and various control methods. These valves include electric valves and manual valves, and are connected to different control systems. Therefore, the control method and power distribution method of these valves are also different in each project. This article summarizes 8 control methods through classification and comparative analysis of these valves, and proposes 8 interface diagrams accordingly, standardizes the control and power distribution methods, and provides a basis for future engineering design and procurement.
