Description

This work investigated the irradiation behavior of gray desert soil holding simulated An4+ waste under an irradiation of 1.5 MeV Xe20+ to fluences from 1 × 1012 to 1 × 1015 ions cm-2. The results indicated that the structure has no obvious change due to irradiation fluences and waste load. The normalized leaching rate of Ce after 28 days of the MCC-1 test is in the order of 1× 10-5 g cm-2 d-1 before and after irradiation. This work identifies gray desert soil, which has good radiation resistance, as a potential matrix for solidification tetravalent actinides. (author)
