Seismic structural analysis of a conceptual waste package design for disposal of high level nuclear waste in a geologic repository

This paper describes the methodology used to perform seismic structural analyses on a conceptual waste package design for the disposal of high-level nuclear waste in a geologic respository. The waste package design analyzed is intended to hold uncanistered spent fuel. The purpose of this analysis is to determine if the proposed waste package design can withstand the seismic loads caused by nearby fault movement during the preclosure period of the repository without breaching the inner or outer waste package barriers or damaging the internal structures, which would affect their ability to separate the waste forms. For uncanistered spent fuel waste packages, this is interpreted to mean that no yielding of the basket structure is permitted
