基于风险指引型设备分级的核电厂电动阀预防性维修周期替代技术的研究

Researchon the Alternative Technique of the Preventive Maintenance Program for Motor Operated Valves Based on the Requirement of Risk-informed Categorization of SSCs

本文基于风险指引型设备分级的要求,确定了核电厂电动阀预防性维修替代技术的具体方法和流程,用于保证核电厂安全经济运行并提高电动阀可靠性。

Based on the requirement of risk-informed categorization of SSCs,the procedure of the alternative technique of preventive maintenance program for motor operated valves at nuclear power units was established in this paper.This method was applied to ensure the safety and economy of power plants,and improve the reliability of motor operated valves.
