(Summary description)Through the joint research of domestic and foreign equipment manufacturing enterprises, China's third-generation nuclear power AP1000 (passive pressurized water reactor nuclear power technology) equipment domestically has made significant progress. National Nuclear Power Technology Corporation previously announced in Beijing that a three-generation nuclear power equipment supply chain has been formed, of which large forgings have been fully produced by domestic heavy industry enterprises.

Unlike the second-generation nuclear power, which has a design life of about 40 years, AP1000, as the third-generation nuclear power technology, fully adopts ASME standards and has a design life of 60 years. As equipment accounts for about 50% of the project cost, it also needs to go through a 60-year life test during operation. Equipment manufacturing and supply are the most critical links in the operation of power stations.

For domestic nuclear power equipment enterprises, the development of AP1000 supporting equipment has allowed domestic nuclear power equipment enterprises to conduct a "big training".

Unlike foreign companies, domestic equipment manufacturers also undertake the task of equipment localization. In the first unit of AP1000, Sanmen Unit 1, Chinese companies were only responsible for components such as steel containment, main pipelines, and pressure stabilizers. However, the fourth unit was Haiyang Unit 2, including reactor pressure vessels and steam generation. The key equipment such as generators, blast valves, and canned motor main pumps will be manufactured by Chinese companies, and the localization rate of the entire unit will also reach the goal of 70%.

In the future, if China 's independent AP1000 technology can go to sea, China 's first pile of construction experience will bring certain competitive advantages to the construction of other AP1000 projects. Since the US AP1000 construction was later than China, the US VOGTLE nuclear power project has already invited six engineering and technical support personnel from the State Nuclear Power Technology Company with experience in the construction of the first reactor of the AP1000 to the United States to provide technical services at the end of last year.

In the construction of another third-generation nuclear power EPR project, the Taishan Nuclear Power Plant in Guangdong, although the start time of this project in China was later than in other countries, the overall construction progress has surpassed, and its construction experience has also given China an advantage in bidding for other EPR projects in the future. .

Pakistan's Chashma nuclear power plant is China's first commercially available pressurized water reactor nuclear power plant, but South Korea's nuclear power, which started at about the same time as China, has taken the lead in nuclear power exports.

In the international nuclear power market, Chinese nuclear power companies are facing fierce competition from other giants. This may include Areva EPR (European Pressurized Water Reactor) technology, General Hitachi ESBWR (Economically Simplified Boiling Water Reactor), APR1400 technology from the Consortium of Korea Hydro and Nuclear Power Plant Corporation, Mitsubishi Heavy Industries 'APWR (Advanced Pressurized Water Reactor) technology and Toshiba The company's ABWR (Advanced Boiling Water Reactor) technology.

Information
Through the joint research of domestic and foreign equipment manufacturing enterprises, China's third-generation nuclear power AP1000 (passive pressurized water reactor nuclear power technology) equipment domestically has made significant progress. National Nuclear Power Technology Corporation previously announced in Beijing that a three-generation nuclear power equipment supply chain has been formed, of which large forgings have been fully produced by domestic heavy industry enterprises.
 
Unlike the second-generation nuclear power, which has a design life of about 40 years, AP1000, as the third-generation nuclear power technology, fully adopts ASME standards and has a design life of 60 years. As equipment accounts for about 50% of the project cost, it also needs to go through a 60-year life test during operation. Equipment manufacturing and supply are the most critical links in the operation of power stations.
 
For domestic nuclear power equipment enterprises, the development of AP1000 supporting equipment has allowed domestic nuclear power equipment enterprises to conduct a "big training".
 
Unlike foreign companies, domestic equipment manufacturers also undertake the task of equipment localization. In the first unit of AP1000, Sanmen Unit 1, Chinese companies were only responsible for components such as steel containment, main pipelines, and pressure stabilizers. However, the fourth unit was Haiyang Unit 2, including reactor pressure vessels and steam generation. The key equipment such as generators, blast valves, and canned motor main pumps will be manufactured by Chinese companies, and the localization rate of the entire unit will also reach the goal of 70%.
 
In the future, if China 's independent AP1000 technology can go to sea, China 's first pile of construction experience will bring certain competitive advantages to the construction of other AP1000 projects. Since the US AP1000 construction was later than China, the US VOGTLE nuclear power project has already invited six engineering and technical support personnel from the State Nuclear Power Technology Company with experience in the construction of the first reactor of the AP1000 to the United States to provide technical services at the end of last year.
 
In the construction of another third-generation nuclear power EPR project, the Taishan Nuclear Power Plant in Guangdong, although the start time of this project in China was later than in other countries, the overall construction progress has surpassed, and its construction experience has also given China an advantage in bidding for other EPR projects in the future. .
 
Pakistan's Chashma nuclear power plant is China's first commercially available pressurized water reactor nuclear power plant, but South Korea's nuclear power, which started at about the same time as China, has taken the lead in nuclear power exports.
 
In the international nuclear power market, Chinese nuclear power companies are facing fierce competition from other giants. This may include Areva EPR (European Pressurized Water Reactor) technology, General Hitachi ESBWR (Economically Simplified Boiling Water Reactor), APR1400 technology from the Consortium of Korea Hydro and Nuclear Power Plant Corporation, Mitsubishi Heavy Industries 'APWR (Advanced Pressurized Water Reactor) technology and Toshiba The company's ABWR (Advanced Boiling Water Reactor) technology.
