The new generation "HanwuHAN5" pressure vessel inspection system independently developed by China Nuclear Power has been successfully applied.

Recently, the new generation "HanwuHAN5" reactor pressure vessel inspection system independently developed by China Nuclear Power's CNNC Wuhan has been successfully used in the pre-service inspection of the third unit of the Sanmen Nuclear Power Plant, successfully completing the pre-service inspection task of the reactor pressure vessel. Compared to traditional inspection systems, "HanwuHAN5" shortens the critical path time for pressure vessel inspection by more than three days. It is not only suitable for second-generation pressurized water reactors, but also adaptable to various mainstream reactor types such as AP1000 and "Hualong One", fully meeting the international in-service inspection regulations such as ASME and RSE-M, and possessing strong versatility and promotion value.
