en.Wedoany.com Reported - At 06:15 on April 10th, Unit 1 of the Hainan Nuclear Power Plant in China successfully synchronized to the grid, marking the official completion of the 108 overhaul. This overhaul was the first decennial major maintenance for Hainan Nuclear Power, involving the completion of over 9,000 maintenance tasks in total. Key projects included the comprehensive disassembly of the No. 2 main pump, the decennial maintenance of the A-train emergency diesel generator and the additional diesel generator, the containment integrated leak rate test, and the in-service inspection of the reactor pressure vessel, among others.
During the 108 overhaul, under the unified leadership of the overhaul headquarters, Hainan Nuclear Power closely collaborated with partner units such as CNNC Operation and Maintenance, CNNC Wuhan, CNNC Maintenance, and Zhejiang Thermal Power. Facing challenges such as numerous key projects, high difficulty in implementing some projects, and complex critical path logic, they made every effort to successfully complete the power supply guarantee tasks for important windows including the National Two Sessions and the Boao Forum for Asia. All overhaul personnel adhered to the safety concept that "safety is the lifeline of the nuclear industry," working together with one heart to overcome difficulties and successfully achieving the safety and quality control objectives of this overhaul.
The 108 overhaul team, through meticulous risk pre-control, standardized operating procedures, and comprehensive safety supervision, firmly upheld the "zero tolerance" bottom line, effectively enhancing the safety and reliability of the unit's equipment. This has laid a solid foundation for the safe and stable operation of the unit in the next cycle. In the future, Hainan Nuclear Power will continue to solidify its safety philosophy, strengthen the implementation of safety responsibilities, ensure the safe and stable operation of its units, and consistently provide safe, clean, efficient, and stable green energy support for the construction of the Hainan Free Trade Port.
