New research carried out by Ohio State University has revealed significant problems with one of the key containment methods for high level nuclear waste to be used in the UK. It had previously been assumed that forming high level waste into glass or ceramics within a stainless steel canister would ensure that the waste would be isolated from its surroundings while it underwent radioactive decay. It now appears that the iron within stainless steel canister is reacting with the silicon, a fundamental constituent of glass. This leads to severe localised corrosion at a far higher rate than previously assumed.
