Abstract
As the critical component for fluid control in nuclear power plants (NPPs), the performance of nuclear valves has direct impacts on the safety of the system. According to ASME OM Code, Subsection ISTC, “inservice test of Valves in Light-water Reactor Nuclear Power Plants” on the inservice test requirements and maintenance practices for valves in NPPs, this paper develops the diagnosis criteria for motor-operated valves (MOVs) in domestic NPPs and the performance evaluation method with the diagnosis examples to provide guidance for reliability management of valves in NPPs.
