en.Wedoany.com Reported - On June 11, Unit 1 of the Tianwan Nuclear Power Plant was successfully synchronized to the grid, marking the safe completion of the OT116 overhaul.

This overhaul fully implemented the concepts of digitalization and standardization. Relying on the full-process operation overhaul management platform, it achieved digital control and standardized operations throughout the entire process, from preparation and execution to summary.

The OT116 overhaul was a Category C overhaul, completing a total of 6,990 standardized overhaul items. Key tasks included the replacement of the generator stator bar, inspection of small branch pipes within the primary circuit pressure boundary, dredging of the marine engineering tunnel, disassembly and overhaul of the removable parts and motor of the No. 4 main pump, disassembly and overhaul of the No. 4 low-pressure cylinder, and modification of the main transformer low-voltage side bus duct. Related work such as operation planning, coordination requests, and personnel organization were all completed through the digital platform, laying a solid foundation for the safe and stable operation of the unit in the next cycle.

As one of the key annual overhaul tasks at the Tianwan Nuclear Power Base, the OT116 overhaul is a critical step in rejuvenating and empowering the unit, strengthening the foundation for high-quality development of Jiangsu Nuclear Power. During the overhaul, Jiangsu Nuclear Power, in collaboration with CNNC Operations and various partner units, coordinated efforts and worked in unison. All personnel involved in the overhaul maintained a strong sense of responsibility, always vigilant about safety, and relied on the digital collaboration platform to complete all overhaul tasks with high quality. This overhaul also marked the first full-process use of the full-process operation overhaul management platform, signifying that overhaul management has entered a new stage of digitalization, process standardization, and normalization.

Standing at a new starting point, Tianwan Nuclear Power will continue to deepen standardization, uphold the safety bottom line, consolidate the production foundation, and continuously supply clean and reliable energy. It will contribute nuclear power's strength to achieving the "dual carbon" goals and promoting the green and low-carbon transformation of the economy and society.
