WWER反应堆压力容器自主化超声检测技术

Independence Ultrasonic Inspection Technique of WWER Reactor Pressure Vessel

某核电厂引进俄罗斯的2台核电机组为WWER型机组,役前和在役检查均由俄罗斯公司采用俄罗斯检验技术实施完成。为实现检验技术自主研发,依据俄罗斯规范的基本要求,通过对超声检测探头参数、缺陷定量技术研究等,形成了一套针对WWER反应堆压力容器超声检测的有效检验技术,实现了WWER反应堆压力容器检验技术的国内自主化。

A nuclear power plant introduced two units of WWER nuclear type from Russia, the Pre-service inspection （PSI） and In-service inspection （ISI） performed by the Russia Company using the Russian inspection technique. In order to realize and develop the independent inspection technique, according to the basic requirements of the Russian standard, based on the research of ultrasonic probe parameters and sizing technique, develop a set of nationalize ultrasonic inspection technique for Reactor Pressure Vessel of WWER nuclear type, and realize the independent inspection technology, then demonstrate the independent inspection technique to become a reality.
