Research of Hafnium Characteristic for Control Rod of Reactor

Metallic hafnium possesses a combination of properties which makes it the preferred material for control rods of nuclear reactors. The chemical composition, mechanical property, the corrosion resistance and the physical characteristics of hafnium were researched during the development of hafnium for control rods of reactors. The results show that the manufacturing method of hafnium plate is appropriate, and the characteristics of materials meet the requirement of control rods.
