Sammanfattning

This work is a continuation of a long-term spent fuel leaching and radionuclides immobilization (by
iron canister) experiment under simulated near-field conditions, in deoxygenated 2 mM NaHCO3
solution with 1 Gy/h γ irradiation. The corrosion of iron canister material was investigated by
electrochemical and microanalytical methods. Significant amounts of radionuclides (U, Np, Tc, Sr) were
found to be immobilized on the corrosion layer of iron canister material by using SEM_WDS and SIMS
methods. The observation is useful for bettering our understanding of near-field chemical processes at
earlier canister failure conditions.
