Description
The concept for emplacement of highly compacted bentonite (HCB) blocks involves a steel framework on which the blocks are placed. Corrosion of this structure would produce planes of iron oxide corrosion products through the bentonite. The structure is designed so that steel components do not extend from the canister to the Opalinus Clay, to ensure that fast transport paths across the bentonite are not created.
