Complementary research
This figure illustrates the complementary nature of the research on radioactive waste. With better 'conditioning', the barriers provided by packages and containers will be improved, in addition to those provided by the concrete structures and geological stratum of the 'deep geological repository'. 'Separation and transmutation' will reduce the amount of waste to be buried, and an extended period of 'storage' will mean that the disposal facilities can be smaller because the packages will have cooled down.
