M310型核电厂在役检查的改进和优化

Improvement and Optimization for In-service Inspection of M310 Nuclear Power Station

核电厂在役检查是核电厂机械设备安全运行的重要保证手段之一。本文结合国内核电厂在役检查的经验反馈,对RSE-M规范中某些技术条款的合理性进行探讨,介绍风险指引型在役检查方法的应用,并为我国M310型压水堆核电厂在役检查的优化提供建议。

In-service inspection（ISI） is an important method to ensure the safety of the mechanical equipments in nuclear power stations. According to the in-service inspection experience feedback from the domestic nuclear power stations, the reasonableness of some provisions in the RSE-M code are discussed and the applications of risk-informed in-service inspection（RI-ISI）are introduced, and the advices for the optimization of the ISI of the domestic M310 nuclear power stations are proposed.
