Abstract

Nuclear energy as an important way to solve the energy crisis, has achieved multi-dimensional utilization in fields of power generation, heating, hydrogen production, seawater desalination, and isotope production. The safe disposal of radioactive waste directly affects the sustainable development of nuclear energy. The solidification of radioactive waste on specific substrates and deep geological disposal is an effective way to achieve permanent shielding of radioactive waste. The paper focuses on the latest developments in the disposal of radioactive waste, and comprehensively elaborating on various solidification disposal technologies for radioactive waste (cement solidification, asphalt solidification, polymer solidification, artificial rock solidification, glass solidification), as well as melting preparation processes (tank method, calcination + induction heating metal melting furnace, Joule heating ceramic melting furnace, cold crucible). In addition, the design principles, confinement mechanism, and application status of typical glass solidification technology were discussed, and the characteristics of typical borosilicate and phosphate glass matrices used to envelop radioactive nuclides were analyzed. Finally, the future development path of radioactive waste solidification disposal was pointed out, and providing reference for promoting the safe and efficient disposal of radioactive waste in the nuclear industry.
