Radionuclide disposal using the pyrochlore supergroup of minerals as a host matrix-A review

This review examines the structural, compositional and chemical properties of radionuclide-containing pyrochlore supergroup minerals. Compiled leaching data for radionuclides hosted in pyrochlores demonstrates that these materials offer a high degree of aqueous durability making them strong candidates for radionuclide disposal, offering a viable storage alternative to traditional vitrification methods.
