The first "Hualong One" nuclear power unit in the Guangdong-Hong Kong-Macao Greater Bay Area begins commercial operation and power generation.

Headquartered in Shenzhen, China General Nuclear Power Group Co., Ltd. announced on the 20th that the first “Hualong One” nuclear power unit in the Guangdong-Hong Kong-Macao Greater Bay Area—the CNG Guangdong Taipingling Nuclear Power Plant Unit 1—went into commercial operation, officially meeting the conditions for commercial operation, with an expected annual power generation of over 9 billion kilowatt-hours. “Unit 1 has previously completed all performance tests and a 168-hour full-power continuous operation assessment. Currently, all parameters are normal and stable, and the unit is in good condition,” said Zhang Guoqiang, Chairman of China General Nuclear Huizhou Nuclear Power Co., Ltd. He added that the construction of Unit 1 fully incorporated previous project experience, completing 26 major design improvements and over 8,300 feedback items. The unit, which was put into operation this time, achieved multiple key technological breakthroughs through independent innovation. It was the first to apply the independently designed HL-T67 steam generator and SH-N non-safety-grade DCS platform by CGN, and the main steam isolation valve was also localized, marking a solid step toward full localization of key equipment. Meanwhile, a zinc passivation technology was used on one loop to coat the pipes with a “anti-corrosion layer,” effectively suppressing corrosion and extending equipment lifespan; decoupled operation on the primary and secondary sides allows the nuclear power plant’s loops to start independently, greatly improving maintenance efficiency. Additionally, the project for the first time launched the digital handover platform 3.0, which uses a 3D plant model to connect the entire chain of design, procurement, construction, and commissioning, forming an integrated data asset, and achieving simultaneous construction and integrated handover of the physical and “digital” power plants, empowering nuclear power management through technological innovation.
