The first "Hualong One" nuclear power unit in Hainan, China has been put into commercial operation

On September 17th, the first "Hualong One" nuclear power unit in Hainan, Unit 3 of the Huaneng Changjiang Nuclear Power Phase II project, was officially put into commercial operation.

The Huaneng Changjiang Nuclear Power Phase II project plans to construct two 1.2 million kilowatt nuclear power units, which is currently the largest power project in Hainan. The unit is equipped with China's fully independent intellectual property rights "Hualong One" third-generation pressurized water reactor nuclear power technology, adopting a safety design concept that combines active and passive methods, significantly improving the reliability and safety level of nuclear power plant operation.

Autonomy and controllability are the most distinctive characteristics of the "Hualong One". The Changjiang Nuclear Power Phase II project is committed to innovation and surpassing on the basis of inheriting mature technology. The project team has implemented 86 design optimizations on the unit according to local conditions, of which 25 involve the "four new" applications of new technologies, new processes, new industries, and new products. The localization rate of the core equipment of the unit reached 98.1%, setting a new high for the localization rate of the "Hualong One" unit.

Faced with the risk of "bottleneck" in key components, the Changjiang Nuclear Power Project team withstood the pressure of the construction period, carried out domestic substitution research, and solved the difficulties of equipment adaptation and working condition verification one by one, successfully forging a practical path of independent and controllable development throughout the entire industry chain. At the same time, digitization and intelligence have become the new highlights of this project. The fully independently developed and controllable nuclear power production management system by China Huaneng, HAP, has been fully put into use. The system integrates video surveillance, 5G communication, AI artificial intelligence and other technologies, and achieves complete independent and controllable software and hardware through full chain localization adaptation, providing solid digital support for the safe operation of nuclear power units. The first digital production command system in the domestic nuclear power industry has been built here, with a wide range of robot inspection scenarios, driving technological innovation through production pain points and exploring a new paradigm for smart nuclear power construction.

Nuclear power is not only a competition of technology, but also a competition of talent and management system. Not only building projects, but also building systems and teams "is the core strategy of Huaneng's entry into the nuclear power field. The project innovation has explored a "DNA" deep participation management model, with more than 200 owner personnel directly incorporated into the engineering construction team, sinking to the construction team, and honing core competencies throughout the entire process of construction. Nowadays, Changjiang Nuclear Power has built a young professional team with an average age of only 30.7 years old and a high proportion of 98% having a bachelor's degree or above. The quality of training for senior operators ranks among the top in the industry.

The landing of Changjiang Nuclear Power Project has effectively promoted the upgrading of Hainan power grid. The supporting transmission project has further improved the main grid structure of the 500 kV island and accelerated the construction of the Guangdong Hainan power interconnection project, effectively reversing the "island" pattern of island energy. According to estimates, the annual power generation of the project after completion can reach 18 billion kilowatt hours, saving over 6.32 million tons of standard coal and reducing carbon dioxide emissions by about 11.6 million tons annually. The power supply capacity of the entire Changjiang Nuclear Power Base will cover more than 50% of the electricity demand in Hainan Province, promoting the proportion of nuclear power installed capacity in Hainan to over 40%, making it the province with the highest proportion of nuclear power in the country.

The smooth commercial operation of this project witnesses a solid step taken by China's independent third-generation nuclear power technology "Hualong One" on the path of mass construction. The Changjiang Nuclear Power Phase II Project carries energy from.
