Abstract

This dissertation proposal covers research work that started in the spring of 1992. The aim of the research has been to study the structural performance and stability of proposed nuclear waste containers and the enclosed fuel rods to be used in the long term storage of High Level Nuclear Waste (HLNW). This research is in two phases, computational and experimental. The computational phase deals with the linear and nonlinear Finite Element Analysis of the different containers due to various loading conditions during normal handling conditions and due to the effect of long term corrosion while the canister is stored in the drift of a backfilled geological repository. The elastoplastic stability of the nuclear fuel rods were studied under body forces resulting from acceleration vectors at varying angles, resulting from a sudden drop of the canister at an angle onto a hard surface.
