压水堆核电站在役检查用无损检测技术发展概况

核电站在役检查是核电站安全运行的重要保证手段之一，核安全法规和导则对核电站核安全设备的役前和在役检查提出了明确的要求。介绍了压水堆核电站在役检查用无损检测技术的发展历程、相应的在役检查标准和规范的使用状况。总结了当前国内外核电站在役检查技术能力验证的实施现状，对我国自主开展核电站在役检查和能力验证工作提供借鉴。

Development Status of NDT Technology for PWR NPP In-Service Inspection

In-service inspection of nuclear power plant is the important way for keeping safety operation. There is specific requirement of nuclear safety rule of law and guide to pre-service inspection and in-service inspection of nuclear safety equipment. History of in-service nondestructive testing development in nuclear power plant was reviewed, the relative application status of ISI code and standard was introduced, the implementation status of performance demonstration of ISI technology between domestic and aboard nuclear power plant was summarized. Some suggestions for Chinese independent development of ISI and performance demonstration were given.
