Abstract: In order to manufacture the CANDU fuel bundles with domestic Beryllium completely, this paper analyzed the operation requirements for the fuel bundles coating with domestic Beryllium, and developed a special production project on the basis of the process qualification, and the bundles had been loaded in the unit 2 of the third Qinshan Nuclear Power Plant for verification test. It shows that the quality and performance of the fuel bundles coating with domestic Beryllium meets the requirements of the Qinshan CANDU units. It will be the best quality to optimize the coating process control.
