Practice on NDE Licensing and Inspection Qualifications for Nuclear Power Plant In-service Inspections

摘要

Along with the rapid development of nuclear power program, nuclear safety authority in China stipulates more strict safety control measures. Among them, as safety related non-destructive examination activities, NDE providers have to get NDE licenses according to HAF601 requirements for domestic suppliers or HAF604 requirements for foreign suppliers before they can provide services such as in-factory NDE or in-service inspections for nuclear power components. On the other hand, inspection qualifications have to be taken before the site pre-service inspection or in-service inspection implements in nuclear power plants. CITEC, the CGNPC Inspection Technology Company, Ltd., is the specific non-destructive examination provider for nuclear power industry. The experiences in NDE licensing and inspection qualification upgrade its capabilities on carrying out various inspection activities. The article describes the experiences and feedbacks from such licensing and qualification processes, and also the practices on pre-service and in-service inspections for various nuclear power components for 1000MW PWR units.
