Description

Hydrogen is produced by anoxic corrosion of steel and the effects must be considered in evaluating the behaviour of the bentonite buffer. Some of the gas produced may dissolve in the porewater, but the gas may also exceed the solubility under repository conditions and be transported through gas channels or capillaries into the surrounding rock.
