Storage and disposal of radioactive waste as glass in canisters

“…Reasons which have been forwarded for routine overpacking include: 1) to provide a stress-free outer canister (this requires stress relief of the seal weld area), 2) to assure low surface contamination of the outer canister, or 3) to provide redundant protection, e.g., the overpack canister could be of a different material, selected to counterbalance weaknesses (to chloride attack, for instance) in the protection afforded by the primary canister. However, a recent study concluded, "... the use of an overpack, as an integral part of design results in an undesirable design and economic constraint on the waste management system" (Bermingham, 1978).…”
