Steel Containment Vessel Ring 1 of Unit 1 at Guangxi Bailong Nuclear Power Plant Successfully Hoisted into Place
At 11:38 on August 16, after 4 hours and 01 minutes of continuous and stable operation, the steel containment vessel ring 1 (CV1R) of the nuclear island of Unit 1 at Guangxi Bailong Nuclear Power Plant was successfully hoisted into place. This hoisting marks another successful installation of a key module following the CVBH and CA20 modules for Unit 1 of Bailong Nuclear Power Plant, signifying a critical breakthrough in the construction of the main structure of the nuclear island of Unit 1. The steel containment vessel consists of five major modules: the bottom head, the intermediate cylindrical shell (rings 1 to 3), and the top head, serving as the third physical safety barrier of the reactor. The CV1R hoisted this time is the core component with the largest volume and heaviest weight among the five major components of the steel containment vessel, measuring approximately 15.5 meters in height and up to 39.6 meters in maximum inner diameter, integrating equipment...

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, Liaoning Nuclear Power, in collaboration with...
