AbstractThe irradiation response of Gd2Zr2O7 ceramic bearing complex nuclear waste was explored by heavy ions to relatively high fluences. The Gd2Zr2O7 ceramic holding 25 wt.% and 40 wt.% of simulated TRPO waste (containing 11 kinds of oxides) were irradiated by 1.5 MeV Xe20+ to fluences ranging from 1.0 x 10(12) ions/cm(2) to 1.0 x 10(15) ions/cm(2) at room temperature. Irradiation induced structure disordering (i.e. phase transformation from pyrochlore to defect-fluorite and finally to amorphous structure) was disclosed by GIXRD, Raman and TEM. The results indicated the structure disordering was influenced by fluences, irradiation depth and waste loading content. This work identified the Gd2Zr2O7 ceramics as a potential candidate in immobilizing complex oxides from the aspect of irradiation tolerance. (c) 2018 Elsevier B.V. All rights reserved.
