Abstract

PURPOSE: To enable the free expansion of axial direction of a nuclear fuel part, by means of using the same material with an end plug and a cladding tube for thermal shielding member which was formed into a shape subjecting to contact only the most cold position of the end plug.
CONSTITUTION: A thermal shielding member 80 is combined with the end of a spring 56, and the thermal shielding member 80 and the central concaved part 69 are contacted at the flat narrow plane near to the point contact, namely a projecting part 84 of the thermal shielding member 80 is contacting with the convex of an inner surface 69 of the upper end plug. The temp. t3 of the central part of the inner surface 69 is lower than the temp. t2 of the surrounding part of the inner surface 69 when jointings of a collar 66 and a tube 44 are in welding, and is of the most low temp. of the inner surface 69 during the normal welding operation. Moreover, because that it is connected to a close winding part 67 of a spring terminal part via a thermal shielding member 80, the temp. is further lowered, and the screwed part by screw structure of the spring and the thermal shielding member, is never melted.
