"Hualong No.1" nuclear power technology has China's independent intellectual property rights. 1 * * * obtained 743 patents and software copyright 104, covering design technology, patented design software, fuel technology, operation and maintenance technology and other fields, and the localization rate reached over 85%.
Hualong No.1 was built by China National Nuclear Corporation, two major nuclear power enterprises in China. (CNNC) and China General Nuclear Power Group (CGN), based on more than 30 years' experience in research, design, manufacture, construction and operation of nuclear power in China, and according to the experience feedback of Fukushima nuclear accident and the latest safety requirements at home and abroad, have developed the advanced nuclear power technology of million kilowatt pressurized water reactor.
As the main brand of China nuclear power "going global", in terms of design innovation, "Hualong No.1" put forward the safety design concept of "active and passive combination", adopted 177 fuel assembly core, multiple redundant safety systems, single reactor layout and double containment, comprehensively and evenly implemented the design principle of "defense in depth" and set up perfect measures for preventing and mitigating serious accidents.
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.
