The world's first "Linglong One" has been crowned successfully~Taiyuan Iron and Steel Stainless Steel has made new achievements

On February 6th, the world's first demonstration project of modular small nuclear reactors on land, the outer dome of "Linglong 1", was successfully lifted and crowned at the Changjiang Nuclear Power Station in Hainan! This marks the comprehensive conclusion of the construction of "Linglong No.1". The stainless steel plates used for the internal components of the Linglong 1 small nuclear reactor are all supplied by Taiyuan Iron and Steel Corporation. "Linglong 1" is the "biological brother" of "Hualong 1", both of which are the third-generation nuclear voltage water reactor technology achievements designed by China Nuclear Power Research and Design Institute. "Linglong 1" and "Hualong 1" are both small dragons (code ACP100) and large dragons (code ACP1000) in terms of volume, and their power generation is basically a 10:1 ratio of 100000 kilowatts and million kilowatts. Modular small reactors (hereinafter referred to as small reactors) have been highly praised by domestic and foreign nuclear power experts for their greater safety and flexibility. According to the International Atomic Energy Agency (IAEA), there are over 80 types of small reactor technologies being developed globally, and nuclear power powers such as the United States, Russia, the United Kingdom, Japan, and South Korea have included small reactor technology in their national strategies. At the current stage, the development of small reactors in other countries is still on paper. China's Linglong 1 is the only third-generation nuclear power small reactor in the world that has passed official review by the International Atomic Energy Agency, and has taken the crucial step of engineering implementation, leading the world. Linglong 1 is not simply miniaturizing large-scale nuclear power plants with dispersed layouts, but rather integrating design and modular construction. High inherent safety is the most prominent feature and requirement of "Linglong One". The application scenarios of small and exquisite piles are closer to users, such as regional centralized heating, industrial park power supply, etc., known as "nuclear mobile power banks". With the original mission of serving the country with steel and building a strong steel nation, Taiyuan Iron and Steel Group has always consciously been at the forefront of advanced stainless steel material research and development. As early as 2016, shortly after becoming the world's first small reactor to pass the International Atomic Energy Agency (IAEA) safety review, Taiyuan Iron and Steel began actively tracking the stainless steel materials required for the small reactor project. In 2021, Taiyuan Iron and Steel provided the main equipment manufacturing unit of "Linglong 1", Dongfang Electric Group Wuhan Nuclear Equipment Manufacturing Company, with first-class stainless steel plates for the manufacture of the core and most critical internal components of "Linglong 1". The core components are the heart equipment of a nuclear reactor, located within the pressure vessel of the primary equipment of the reactor. They are difficult to manufacture, have a long processing cycle, and have high assembly accuracy. They not only support the fuel components of the nuclear reactor, but also provide shielding and protection for the core and pressure vessel, support and guidance for various measuring devices, and play an important role in achieving nuclear safety operation. They are known as the "keel" of a nuclear reactor. After the completion of the Linglong 1 demonstration reactor, it will undoubtedly become a turning point in the nuclear energy industry, ushering in a new era of multi-purpose nuclear energy. More and more commercial small reactors will appear in China's islands, mining areas, industrial parks, remote areas, etc. Linglong No.1 is another major achievement in China's independent innovation of nuclear power after Hualong No.1, filling the domestic gap and having broad global market prospects. It is expected to become another beautiful "national business card" of Made in China.
