Abstract

PURPOSE: To prevent the stress corrosion cracking of a cladding tube, by means of setting up a lining layer at the inner surface of the cladding tube.
CONSTITUTION: A lining layer 8 is coated containing Beryllium at the inner surface of a cladding tube 30, and therein a fuel pellet 4 is contained. The Beryllium contained in the lining layer 8 releases α particles, namely He atomic nucleus by means of receiving the irradiation of fast neutron generating during the reactor is in operation. Accordingly, He gas is accumulated attended with the irradiation of the nuclear fuel rod in gaps 7 of the cladding tube 30 and within a plenum, and the mol fraction of the He gas is increased. This He gas is a good gas in heat conductivity and the deteriozation of a gap conductance is restrained, and the temp. lowering of the fuel pellet is brought. And the discharging rate of F.P. gases are lowered, and the generation of corrosive atomosphere can be prevented.
