CNNC Jianzhong Nuclear Fuel Co., Ltd（CJNF）. which is a wholly-owned subsidiary of CNEIC. It is an indispensable and important link in the nuclear fuel cycle and nuclear power development in China. After more than 50 years of development, CJNF has become a large state-owned enterprise with uranium assembly manufacturing as the leading industry and spices, lithium metal and lithium battery as the main non-nuclear civilian products.
CJNF has a national enterprise technology center and postdoctoral research station. CJNF has advanced equipment, technology advanced uranium assembly production line, have mastered FA300, AFA3G, TVS, to 2 m, China's own brand uranium assembly manufacturing technology such as "HUALONG 1" CF, with 300 mw, 600 mw, 1000 mv, reactor experiment, low temperature nuclear heating reactor components, as well as various types of fuels such as primary, secondary neutron source, the control rods, burnable poison rods, choke plug components related to the core of nuclear fuel components supply capacity. The production capacity of uranium assembly reaches 800 tons of uranium per year, which is the largest uranium assembly manufacturing base in China.Up to now, CJNF has manufactured and provided more than 15,000 sets of high-quality uranium assemblies to Qinshan Phase I, Qinshan Phase II, Daya Bay, Lingao, Tianwan, Hongyanhe, Ningde, Fuqing, Yangjiang, Changjiang, Fangchenggang and Chashma nuclear power station in Pakistan. All uranium assemblies have maintained good operation in the reactor, which has made positive contributions to the safe and stable operation of China's nuclear power plants, won praise and trust from users at home and abroad, and was hailed as China's "nuclear power granary" by the central mainstream media.
