On April 14, 2025, our engineering service team successfully completed the on-site technical service for the opening of the cover after the cold test of Unit 3 of Changjiang Nuclear Power Plant. 

At this point, the fully synchronized integral reactor pressure vessel main bolt tensioning machine developed and manufactured by Raymond Cyber successfully completed the 51st opening/closing operation of the nuclear reactor in the nuclear island. The entire project achieved zero deviations and zero delays, providing a solid guarantee for the subsequent progress of the unit. It also marks that the key operation capabilities of China's independently developed third-generation nuclear power technology "Hualong One" demonstration project have reached a new level.
