A long‐term storage facility or archive. One preferred approach to the safe and sustainable management of nuclear waste is long‐term underground storage of the waste in specially developed and managed sites, but efforts to set up such repositories have been hampered by public opposition. Key site requirements for nuclear waste repositories include the following: the site must be away from major centres of population, the site must be accessible by road and rail, geological conditions must be suitable (it must be possible to tunnel, for example), prospects of minimizing groundwater contamination must be good, it must be possible to store radioactive waste safely there for at least 10 000 years, and the site must be geologically stable (away from fault lines and earthquake zones). The controversy surrounding the proposed repository at Yucca Mountain in Nevada illustrates some of the complexity of the issues involved.
