Important progress has been made in the localization of third-generation nuclear power main equipment

on November 13, the procurement contracts for modules of Zhejiang Sanmen Nuclear Power Plant Units 1 and 2 and Shandong Haiyang nuclear power plant units 1 and 2, as well as the procurement contracts for containment of Sanmen Nuclear Power Plant units 2 and Haiyang nuclear power plant units 1 and 2, which are China's third-generation nuclear power autonomous support projects, were officially signed in Beijing. Wang Binghua, Secretary of the Party group and chairman of the board of directors of National Nuclear Power Technology Corporation, sun Hanhong, member of the Party group, deputy general manager and general manager of AP1000 project management organization (APM), as well as heads of engineering management department, equipment department and other relevant functional departments jointly witnessed the whole process of signing the procurement contract

Xia Zhiding, general manager of National Nuclear Engineering Co., Ltd., and Li Jun, general manager of Shandong Nuclear Power Equipment Manufacturing Co., Ltd., signed the procurement contract for localization modules and steel containment of the third generation nuclear power support project on behalf of the purchaser and the manufacturer respectively. This is another important milestone in the engineering construction of China's third-generation nuclear power AP1000 localization support project, following the signing of the procurement contract for localization pressure vessels and steam generators of the third-generation nuclear power support project on September 26

compared with other built nuclear power stations in China, AP1000 nuclear power station adopts a unique double-layer containment structure. It is reported that the outer containment is mainly reinforced concrete structure, and the inner containment is steel containment, which significantly improves the safety of nuclear power station. At the same time, AP1000 nuclear power plant adopts standardized, modular design and factory prefabrication technology, which effectively shortens the construction period and improves the standardization level and quality of construction. The module procurement contract, and then the comprehensive analysis of the curve is the double space structure, and the signing of the steel containment procurement contract marks another substantive and important step in the localization of the main equipment of the third-generation nuclear power AP1000 support project

it is reported that the steel containment of Sanmen Nuclear Power Plant Unit 1, one of the four units of China's third-generation nuclear power projects, is an AI type equipment, which is purchased by Westinghouse in accordance with the contract. The steel containment shells of the other three units are domestic equipment, and the working principle of the small-scale tensile test motor gas of the national electronic universal testing machine, the general contractor of the nuclear island project of the third-generation nuclear power project, is debugged first. The zero value nuclear power technology company authorizes its member enterprise, National Nuclear Engineering Co., Ltd., to be responsible for purchasing
