<正>The disposal of spent nuclear fuel is a long-standing issue in nuclear ***,UO_2 and metallic U arc used as a fuel in nuclear *** nuclear fuel contains fission products and transuranium elements,which would remain radioactive for 10~4 to 10~8 *** this brief communication,essential concepts and engineering elements related to high-level nuclear waste disposal are *** design models are described and discussed considering the long-time scale activity of spent nuclear fuel or high level *** of physical and chemical barriers to contain nuclear waste are *** regarding integrity,self-irradiation induced decomposition and thermal effects of decay heat on the spent nuclear fuel are also *** question of retrievability of spent nuclear fuel after disposal is considered.
