Abstract

An end plug is for welded disposition within the end of a nuclear fuel rod cladding tube. The end plug includes a plug body having an exterior portion and an insert portion, the exterior portion having a tube-engaging face (9’) and a non-engaging face. An axially oriented surface extends between the tube-engaging face and the non-engaging face. The insert portion is integral with the exterior portion and structured for insertion into the cladding tube. The exterior and insert portions each have a predetermined cross-sectional dimension, the cross-sectional dimension of the external portion being greater. The tube-engaging face is defined at the intersection of the exterior and insert portions. A circumferential groove (21’) in the axially oriented surface, proximate the tube-engaging face, collects weld puddle material, thereby permitting a relatively flat weld.
