Second Ring of Steel Containment Vessel for Reactor Building of Unit 2 at Xudabao Nuclear Power Plant Successfully Hoisted into Place

At 9:57 on August 4, the second ring of the steel containment vessel (hereinafter referred to as CV Ring 2) for the reactor building of Unit 2 at Xudabao Nuclear Power Plant was successfully hoisted into place.

The CV Ring 2 hoisted this time is the third ring segment of the steel containment vessel for Unit 2, with a hoisting weight of nearly 890 tons. During the assembly phase, the installation of multiple discipline items, including annular air ducts, steel structural annular corridors, and U-shaped supports for air turbulence, was completed simultaneously for this module, effectively reducing the risk of cross-operation interference in subsequent internal construction of the nuclear island. This approach fully leveraged the advantages of modular construction and effectively translated the concept of "modularize wherever applicable, prefabricate wherever installable" into tangible engineering outcomes.

During the assembly and hoisting of CV Ring 2 for Unit 2, the modular construction party member commando team formed by Liaoning Nuclear Power together with all participating construction units fully absorbed the experience and feedback from the assembly and hoisting of Unit 1. Relying on the modular assembly construction coordination meetings and the daily tracking mechanism for hoisting progress, the team effectively resolved construction constraints through reform measures, successfully achieving the hoisting of CV Ring 2 for Unit 2 and providing strong support for the subsequent construction of the reactor building of Unit 2.
