Hualong-1, a symbol of Chinese technological innovation, is set to reach a crucial milestone in 2025. This third-generation nuclear reactor embodies China’s energy ambitions, combining safety, efficiency and respect for the environment. At a time when the world is looking for sustainable solutions to climate challenges, Hualong-1 is positioning itself as a key player in the global energy transition.
This breakthrough promises to transform the energy landscape, while strengthening China’s position on the international stage. Find out how this technological feat could redefine the future of nuclear power and its implications for the global industry.
Project progress and hot functional test
The Zhangzhou nuclear power plant project in China has reached a crucial milestone with the completion of the hot functional test on its second unit. This test, which is essential prior to fuel loading, involves raising the temperature of the reactor’s cooling system to check that the safety and cooling systems are operating correctly.
This success paves the way for the next stages, including fuel loading and connection to the national grid. Scheduled to enter commercial operation by the end of the year, the unit is part of China’s efforts to boost its energy capacity while reducing its carbon footprint.
Hualong-1 technology and plant design
The Hualong-1 reactor, a major breakthrough in third-generation nuclear technology, embodies China’s progress towards advanced, self-sufficient energy solutions. Owned by CNNC-Guodian Zhangzhou Energy Company, a joint venture between CNNC (51%) and China Guodian Corporation (49%), this three-loop pressurized water reactor incorporates elements from the ACP1000 and ACPR1000+ models.
The Zhangzhou plant, which will eventually comprise six units with a total capacity of 7.2 million kilowatts, aims to meet China’s growing energy needs while reducing carbon emissions. This initiative is in line with Beijing’s objective of increasing the share of nuclear power in the country’s electricity production.
Environmental impact and energy transition
Once fully operational, the Zhangzhou nuclear power plant will reach an installed capacity of 7.2 million kilowatts, generating over 60 billion kilowatt-hours of clean electricity per year. This production will reduce the use of standard coal by 3.12 million tonnes and CO2 emissions by 8.16 million tonnes annually, equivalent to the planting of 70 million trees.
This project is in line with China’s objectives to double the share of nuclear power in its electricity production to 10% by 2035, thus making a significant contribution to the transition to low-carbon energy and the reduction of national emissions.
