主 题:Spent nuclear fuel disposal Corrosion assessment Hydrogeological modeling
摘 要:This paper presents a corrosion assessment of copper spent nuclear fuel disposal canisters in crystalline rock,using hydrogeological modeling.A simplified approach is considered,to avoid complex and time-consuming computer *** simplified case is presented as a base case,with changes in the hydrogeological parameters presented as variant *** results show that in Taiwan’s base case,decreasing the hydraulic conductivity of the rock or decreasing the hydraulic conductivity of dikes results in a shorter transport path for sulfide and an increase in corrosion ***,the estimated canister failure time is still over one million years in the variant cases.
