What is the life span of Hualong-1?

The life span of Hualong No.1 is 60 years.

The reactor adopts 177 core design, and the core design refueling cycle is 18 months. Innovative technologies such as "active and passive" combined safety system and double containment are adopted to meet the requirements of the highest international safety standards in terms of safety. At present, the world's first reactor of Hualong No.1 has been put into commercial operation, the first overseas reactor has been officially connected to the grid for power generation, and other units under construction are progressing smoothly.

After each unit of Hualong No.1 is put into production, it can generate nearly 65.438+000 billion kWh of electricity every year, which can meet the annual production and living electricity demand of 65.438+000 million local people, equivalent to reducing 36.5438+020 million tons of standard coal and 86.5438+060 million tons of carbon dioxide emissions every year, equivalent to planting more than 70 million trees. On March 25th, 2023, with the successful completion of the 168-hour trial operation test, the first "Hualong No.1" nuclear power unit in western China, Unit 3 of Guangxi Fangchenggang Nuclear Power Station of China General Nuclear Power Group, officially met the commercial operation conditions.

Significance of research and development of Hualong No.1

As the main brand of China's nuclear power going abroad, Hualong No.1 put forward the safety design concept of "active and passive combination" in design innovation. It adopts the core of 177 fuel assembly, multiple redundant safety systems, single reactor layout and double containment, comprehensively and evenly implements the design principle of defense in depth, and establishes perfect measures to prevent and mitigate serious accidents. Its safety index and technology have reached the international third generation nuclear power technology.

Hualong No.1 embodies the wisdom and painstaking efforts of nuclear power builders in China, realizing the unity of advancement and maturity, the balance of safety and economy, and the combination of initiative and passivity. It has a comparative advantage in international competition, and is expected to fill the domestic technical gap in a short time, and has the conditions to participate in international bidding.
