WELDING DEVELOPMENT FOR FABRICATION OF CVTR ZIRCALOY FUEL ASSEMBLIES. Sub- Task 6.01: FUEL ELEMENT CLADDING AND METAL JOINING OF FUEL ASSEMBLIES. Terminal Report

Technical Report ·
OSTI ID:4836808

Welding techniques and weld joint configurations were developed which satisfied design and production requirements for the CVTR Zircaloy fuel assembly. Emphasis was placed on simplicity of joint design and welding procedures to provide maximum weldability. The tungsten inert-gas shielded arc welding process was used exclusively. The unique CVTR core design required the welding of pre- oxidized Zircaloy components. The as welded assemblies require a post welding oxidizing treatment. Test weldments of pre-oxidized Zircaloy components were corrosion tested and subsequently destructively tested to evaluate this assembly sequence. (auth)
