On November 28, 2023, China's leading high-performance stainless steel pipe technology provider:TGJT, announced:
The manufacturing technology of hexagonal boron stainless steel seamless tubes developed by TGJThas passed the scientific and technological achievement evaluation of the China Nuclear Energy Industry Association. The expert group unanimously believes that this technology provides material and technical support for the localization of VVER nuclear power plant spent fuel pool storage racks, has independent intellectual property rights, is a pioneering technology in China, and has reached the international advanced level.
Boron stainless steel has good thermal neutron absorption and γ The radiation shielding characteristics of hexagonal boron stainless steel seamless tubes are widely used in the storage racks and nuclear fuel transfer containers of VVER nuclear power plant spent fuel pools, as well as in the field of spent fuel reprocessing. They are key materials for nuclear fuel cycle systems.
This achievement marks China's successful breakthrough and mastery of the manufacturing technology for seamless hexagonal boron stainless steel pipes with integrated functionality and structure, achieving commercial production of this type of material,
