TISCO Overcomes The Difficulties Of High-end Stainless Steel Materials For Nuclear Power Again

Recently, TISCO has successfully completed the production of 314 pieces of 1522 tons of high-end stainless steel 316H for nuclear power plant in Xiapu, the China’s first fourth-generation nuclear power project demonstration fast reactor in Fujian. That Makes new achievements in construction.

“Fast reactor” is the abbreviation of fast neutron breeder reactor. It is the preferred reactor type of the world’s fourth-generation advanced nuclear energy system. It represents the latest development direction of nuclear energy in the world.

Since 2016, China has begun construction of the first 600MW demonstration fast reactor nuclear power unit in Xiapu, Fujian Province. This project is listed as a major national nuclear energy technology project chapter.

Since the main equipment such as fast reactor container and internal components are under high irradiation and high temperature environment, the comprehensive performance requirements of materials such as radiation resistance, high temperature resistance, corrosion resistance, fatigue resistance and stability are extremely high. It poses a new challenge to traditional stainless steel and its manufacturing technology.

From understanding project requirements, mastering material characteristics, optimizing technical parameters such as chemical composition, mechanical properties, grain size, corrosion resistance, and production test tracking.

“When the epidemic was serious, it was the most stressful day of production. At that time, there was not much to worry about. Overtime and overtime just reduced personnel contact. As the first fourth-generation nuclear power project of China’s independent design, construction, and operation, we must overcome this problem to ensure that the project uses our stainless steel as scheduled. “Yin Wei, the project’s chief technical officer, said.

Taigang joined the China Fast Reactor Industry Technology Alliance as early as 2010, and has been relying on its own advantages in process, equipment, manufacturing technology, etc. to strengthen joint research with domestic institutions and enterprises, and has broken through the demonstration fast reactor 316H high purity. Stainless steel continuous casting, high-purity 316H electroslag ingot smelting, forging, and 40-95mm thick 316H stainless steel plates for internal components of the reactor are currently supplying more than 4,000 tons to the fast reactor project, which strongly supports the national major engineering construction.

Nuclear power is an important symbol of China’s creation to the world. As a production base for stainless steel for nuclear power in China, TISCO contributes its own strength to the country’s nuclear power technology striding forward to the world.
