Description

A gas pressure may be generated in a sealed canister. This could arise from fission gas and He release. It is assumed that no water is present in spent fuel rods at the time of sealing in canisters, because fuel assemblies will have been in dry storage for decades prior to emplacement in disposal canisters.
