At 17:28 on March 12, the first "Hualong One" nuclear power unit in the Yangtze River Delta region, Unit 1 of CGN's Zhejiang San'ao Nuclear Power Project, was successfully connected to the grid for the first time and generated its first kilowatt hour of electricity, marking that the unit officially has the ability to input power to the grid and has taken a key step towards the goal of being officially put into operation.
Unit 1 of the Sanao Nuclear Power Project started construction on December 31, 2020. After being connected to the grid, it was confirmed on site that the unit was operating in good condition and all technical indicators were in line with design expectations. Next, the unit will enter the stage of trial operation under load, and power improvement and various performance tests will be carried out as planned. It is expected to be officially put into production in the first half of 2026.
"As an important part of energy security in the Yangtze River Delta, the San'ao Nuclear Power Project plans to build six 'Hualong One' nuclear power units, and construction of three units has already started." Du Yanhui, Secretary of the Party Committee and Chairman of CGN Cangnan Nuclear Power Co., Ltd., said that after the project is fully completed, the annual power generation capacity is expected to exceed 54 billion kilowatt-hour, which is close to the current total electricity consumption of the entire society in Wenzhou City, which can meet the annual production and living electricity needs of more than 5 million people. It is equivalent to reducing standard coal consumption by more than 16.35 million tons per year, reducing carbon dioxide emissions by about 50 million tons, and is equivalent to adding more than 120,000 hectares of afforestation area. The steady advancement of the Sanao Nuclear Power Project will continue to provide clean energy support for the green and low-carbon transformation and smart economic development of the Yangtze River Delta region.
During the project construction process, digital and intelligent technologies have been widely used. In terms of digital and intelligent construction, the project comprehensively builds a nuclear power "smart construction site" to achieve "visualization, automation, and intelligent" management and control of the work site, reducing manual workload by approximately 700,000 man-hours per year. It has developed and put into use the first domestic nuclear power plant radiographic intelligent management system that integrates radiographic digital management, AI intelligent assessment, and intelligent duplicate checking functions to realize the digitization of the entire process.
