Design Considerations for a Hot Cell Overpack Welder and Overpack for the Waste Isolation Pilot Plant

Abstract

The functional requirements, design considerations, and the approach that is proposed for the waste overpack welding system and the overpack design for the Waste Isolation Pilot Plant (WIPP) are discussed. Included are the results of a comparative evaluation of alternative overpack body-to-head weld joint configurations, welding processes, and welding equipment that was performed in support of the welding system selection.
