wastes, leads to the generation and accumulation of H2 gas in the backfilled emplacement
tunnels, which may significantly affect long-term repository safety. Previous studies have
used H2 generation rates based on the volume of the waste or canister material and the
stoichiometry of the corrosion reaction. However, Fe corrosion and H2 generation rates vary
with time, depending on factors such as amount of Fe, water availability, water contact area …
