Assuring the Completeness of Closure Welds in Cirene Fuel Elements

Abstract

A high level of product quality has been achieved in the end cap welding of CIRENE fuel elements, thanks to development of the initial sheath/end cap contact geometry and parameters of the welding process itself. Successful qualification and manufacturing demonstration confirmed the adequacy of the process for production of reliable nuclear fuel. The approach and principles used in this program can be applied to other types of fuel with a similar design.
