Relaxation behaviour of copper in disposal canisters

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review

    Abstract

    A full 3D creep FE analysis has been performed for the nuclear waste disposal canister with a cast iron insert and a copper overpack under external pressure. The FE mesh of the canister contains a model of the joint line hooking and the oxide particle zone, where the strength of the material is assumed to be zero. The material model includes elastic, plastic, creep and relaxation models. The total strain distribution after predicted 1000 years of exposure are presented.
