-- Congratulations on the successful completion of the first opening operation of the reactor pressure vessel overall bolt tensioning machine for the T501 maintenance of Unit 5 of the Tianwan Nuclear Power Plant. 

On September 8, 2021 at 22:00, the "first opening operation service of the reactor pressure vessel overall bolt tensioning machine for the T501 overhaul of Unit 5 of Tianwan Nuclear Power Plant" undertaken by Beijing Leiming Saisuojishi Technology Co., Ltd. was successfully completed. 

The 5th and 6th units of Tianwan Nuclear Power Plant adopt the improved M310 reactor type from China National Nuclear Corporation, with a scale of 2×1118 MWe pressurized water reactor units. The integral full-synchronous bolt tensioning machine for the reactor pressure vessels of the 5th and 6th units of Tianwan Nuclear Power Plant is our company's "M310" reactor type integral full-synchronous bolt tensioning machine following the "Hualong One" reactor type and the "Guohetang One" reactor type (CAP series). It successfully completed the first opening of the cover operation service during the T501 major overhaul, marking the official entry of domestic integral full-synchronous bolt tensioning machines into the new journey of nuclear power major overhaul. It also verifies that our company has achieved the independent research and development capability of integral full-synchronous bolt tensioning machines for the entire series of reactor pressure vessels of major pressurized water nuclear power reactor types under construction and in operation in China. 

Facing the new challenges of the first major nuclear power overhaul, the Raymond Cyber Engineering Services team meticulously planned, carefully deployed, coordinated comprehensively, and jointly advanced, writing a new chapter for the application of the domestically produced integral full-synchronous bolt tensioning machine in the nuclear power field.
