China's first self-developed
zirconium alloy material to meet the requirements of third-generation nuclear power -- CF3 nuclear fuel assembly N36 zirconium alloy material, the first batch of batch products successfully rolled off the production line and passed the acceptance. This marks the break of the foreign monopoly of the "neck" link, in the large-scale application of the road and a solid step.
Fuel assembly is the core of nuclear reactor, its safety and reliability depend on zirconium alloy cladding. Zirconium alloy material is the key structural material of nuclear reactor core. As the "bone" and "skin" of fuel assembly, zirconium alloy material is known as the "first safety barrier" of nuclear reactor. It plays an important role in the safe and stable operation of nuclear power plant and is one of the important indexes to evaluate the research and development level of fuel assembly. For a long time, zirconium alloy materials used in fuel assembly of domestic nuclear power plants basically depend on import.
