Xe20+ irradiation effects on soil holding simulated An4+ waste

This work investigated the irradiation behavior of gray desert soil holding simulated An(4+) waste under an irradiation of 1.5 MeV Xe20+ to fluences from 1 x 10(12) to 1 x 10(15) 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 x 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. [GRAPHICS] .

Automated summary

This study investigated the irradiation behavior of gray desert soil holding simulated An(4+) waste under 1.5 MeV Xe20+ irradiation. The results showed that the soil structure did not change significantly under different irradiation fluences and waste loads. The normalized leaching rate of Ce was consistent before and after irradiation, at 1 x 10(- 5) g cm(- 2) d(- 1).
