Description
Desaturation of EDZ occurs due to i) ventilation and degassing during the operational phase and ii) gas generation during the post-closure phase. Resaturation of EDZ occurs due to the presence of a hydraulic gradient and gas dissolution. The duration of the desaturation and saturation periods may have significant effects on other safety-relevant processes (cement dissolution, waste dissolution, etc.).
