Abstract

PURPOSE: To improve the reliablity of X-ray inspection of an end plug welding part, by means of forming the end plug part to be welded to a cladding tube into a concaved shape most suitable for the reduction of absorbing X-ray.
CONSTITUTION: An end plug 10 (a diameter of 6.5mm) for the purpose of sealing the end part of a frel cladding tube 2 (for example, and inner diameter of 5.6mm) containing the fuel pellets, are formed by a portion 20 (an outer diameter of 5.55mm) for inserting one part into the cladding tube 2, and the end of the inserting portion into the cladding tube 2 is formed to a concaved part by boring. For the X-ray inspection of the welding part 30 of the end plug 10 and the cladding tube 2, X-ray photograph is taken by means of allowing X-ray 34 radiated from a X-ray radiation bulb 32 via a mask 33 to be refected at the prescribed angle below 90 to the longitudinal direction of the fuel rod, and of inserting a X-ray penetration regulating panel 50 which is composed of the same material as the end plug for the purpose of uniformizing the blacking degree on a X-ray film 31
