Concrete Placement Completed for Raft Foundation of Circulating Water Pit on North Side of 5BMX Turbine Generator Building at Fangchenggang Nuclear Power Plant

On August 30, the concrete placement for the raft foundation of the circulating water pit on the north side of the 5BMX turbine generator building at the Fangchenggang Nuclear Power Plant in Guangxi, undertaken by China Energy Engineering Group Anhui Electric Power Construction No.2 Engineering Co., Ltd., was completed. The total concrete volume placed was 796 cubic meters, with two truck-mounted concrete pumps operating simultaneously, and the work was completed in approximately 22 hours. The circulating water pit raft foundation is a key underground structure of the turbine hall. This mass concrete placement was carried out using the horizontal layered pouring method. The project department made advanced overall arrangements, refined the construction plan, and organized safety and technical briefings for construction. During the placement, project personnel performed their respective duties with coordinated collaboration, efficiently advancing concrete transport, placement, vibration, surface finishing, curing, and other tasks. Dedicated personnel were assigned for on-site supervision to strictly control key parameters such as pouring speed, vibration depth, and slump, and to rigorously implement safety and quality control measures, ensuring the entire construction process was safe, controllable, and quality-compliant. Ultimately, this critical civil construction milestone was successfully completed, laying a solid foundation for the subsequent circulating water system construction and the overall structural construction of the turbine hall.

CA01 Module of Unit 1 at Guangxi Bailong Nuclear Power Plant Successfully Hoisted into Position in the Nuclear Island

On August 29, the CA01 module of Unit 1 at the Bailong Nuclear Power Plant of SPIC Guangxi Nuclear Power was precisely positioned, marking a new phase of parallel civil construction and installation in the nuclear island. ▲On August 29, the hoisting operation of the CA01 module of Unit 1 at the Guangxi Bailong Nuclear Power Plant of SPIC was proceeding in an orderly manner. The CA01 module is located in the reactor building of the nuclear island and serves as the installation room for main equipment such as the reactor pressure vessel, steam generators, and pressurizer. The module is T-shaped in overall form, with external dimensions of 28 meters in length, 29 meters in width, and 24 meters in height. It consists of 47 sub-modules, with a total lifting weight of approximately 1,167 tons, making it the largest and heaviest structural module in the nuclear island. The hoisting operation commenced at 8:07 a.m. and, after a series of maneuvers including lifting, hovering, slewing, lowering, and adjustment, was successfully positioned at 12:58 p.m., with the entire process being safe, controllable, stable, and orderly.

Fangchenggang Nuclear Power Station Unit 2 Completes First Ten-Year Overhaul

On the morning of August 25, Unit 2 of CGNPC Fangchenggang Nuclear Power Station successfully synchronized to the grid on its first attempt following the 7th overhaul, marking the completion of the F207 overhaul undertaken by CGNPC Service Maintenance Company. This overhaul was the first ten-year overhaul since Unit 2 was put into commercial operation. The maintenance process achieved the goal of "no indicator events in safety, quality, and schedule," and made breakthroughs in charging pump maintenance and nuclear-grade socket welding operations. During this overhaul, the nuclear-grade socket welding project was implemented on-site for the first time. To ensure work quality, the maintenance team completed preparatory work in advance, including welding procedure qualification certification, skill qualification process card review and submission, test piece welding, and non-destructive testing, all of which passed acceptance.

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...

First Concrete Pour (FCD) Successfully Completed for the Conventional Island of Unit 2 at Guangxi Bailong Nuclear Power Plant

At 10:06 on August 9, after 38 hours and 46 minutes of continuous effort, the First Concrete Pour (FCD) for the conventional island of Unit 2 at the SPIC Guangxi Bailong Nuclear Power Plant was successfully completed, marking the full commencement of the main construction phase for the conventional island. The basement floor slab of the conventional island of Unit 2 adopts an integral raft foundation, divided into 9 construction zones using the sequence method. This concrete pour covered Zone 1, starting at 19:20 on August 7, with a cumulative pour of 1,732 cubic meters of concrete, conducted safely and orderly throughout the process. Since July, Typhoon Maysak directly struck Fangchenggang, bringing successive storms, followed by days of high temperatures at the Bailong nuclear site, posing significant challenges to on-site construction. In response...
