On January 24, China Nuclear Power Group announced that the first batch of zirconium alloy materials, cf3 nuclear fuel assemblies, which met the requirements of the third generation of nuclear power, developed by China, was successfully downgraded and accepted. Its comprehensive performance index is in the international advanced ranks, and shipment for cf3 nuclear fuel element manufacturing.This marks that our country has broken the foreign long-term monopoly and made a solid step on the road of large-scale application.This is also another important achievement for the China Nuclear Power Group to thoroughly implement the spirit of the 19th National Congress of the Party and the spirit of the series of important instructions of General Secretary Xi Jinping, and to provide strong support for the transition from a nuclear power to a nuclear power.
Yang Changli, deputy general manager of CNPC, and Li Guanxing, academician of the Chinese Academy of Engineering, witnessed the shipment of more than 2400 N36 zirconium alloy coated tube products.This product is developed by China Nuclear Power Research and Design Institute and produced by Western New Zirconium Nuclear Materials Technology Co., Ltd.t the ceremony, the new zirconium and CCRC signed the agreement on the first batch of products of n36 zirconium alloy tube bar and the following product supply framework agreement.
Fuel assembly is the core of nuclear reactor, and its safety and reliability depend largely on zirconium alloy cladding.Zirconium alloy is the key structural material in nuclear reactor core. As the "skeleton" and "skin" of fuel assembly, zirconium alloy is called the "first safety barrier" of nuclear reactor.It plays an important role in the safe and stable operation of nuclear power plants and is one of the important indexes to evaluate the R & D level of fuel assemblies.For a long time, zirconium alloy material for fuel assembly of nuclear power station basically depends on import. Zirconium alloy material has become the main bottleneck of nuclear fuel industry development in our country, and it is the main short board of nuclear fuel industry.
