China National Nuclear Power Self-Developed New Generation "Hanwu·HAN5" Pressure Vessel Inspection System Put into Service

Beijing News Shell Finance Report: On March 21, according to China Nuclear Power, recently, China Nuclear Power’s subsidiary, CNNC Wuhan, independently developed a new generation of “Hanwu・HAN5” reactor pressure vessel inspection system successfully deployed during the pre-operational inspection of Unit 3 at Sanmen Nuclear Power Plant. It has successfully completed the full-range pre-operational inspection of the reactor pressure vessel, opening a new path for the自主升级 of China’s nuclear power unit pressure vessel inspection technology.

It is understood that this system is based on China Nuclear Power’s first batch of centralized R&D projects, “Multi-task high-integration second-generation reactor pressure vessel inspection system development.” After three years of technical research, it has achieved core technical indicators such as five inspection tools operating in parallel and controlling the critical path time within five days. Compared to traditional inspection systems, “Hanwu・HAN5” shortens the critical path time for pressure vessel inspection by more than three days. It is not only suitable for second-generation plus reactors but also adaptable to various main reactor types such as AP1000 and Hualong One, fully meeting international in-service inspection standards like ASME and RSE-M, with strong versatility and推广价值.
