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.
