On April 10, 2025, our engineering service team successfully completed the on-site technical service for the opening of the cover after the thermal test of Unit 2 of Zhangzhou 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 its 50th opening/closing operation of the nuclear reactor in the nuclear island. This milestone marks a significant leap in China's nuclear power operation equipment from "domestic substitution" to "technological leadership". It not only verifies the stability of domestic technology but also provides key technical support for the energy equipment safety strategy during the "14th Five-Year Plan" period.
