Disposal of radioactive wastes (DRW) will eventually hinder the sustainable development of nuclear energy. Aimed at tackling the exposure risk of radioactive waste transport in the groundwater system of disposal sites, this paper presents a review on DRW along with site selection, radionuclide transport experiments and numerical models. Numerical models for radionuclides transport have made great progress through advection-dispersion and linear sorption (Kd) to multi-component reactive transport models.
