Geologic repositories for the long-term storage of spent nuclear fuel (SNF) are limited in their capacity by the amount of decay heat emitted by the SNF. The largest long-term contribution to this decay heat comes from the transuranics (TRUs), the destruction of which could increase storage capacity by a factor of at least 10. A design concept for a subcritical gas-cooled fast transmutation reactor (GCFTR) fueled with TRUs from SNF is being developed. This paper presents the results of analyses of several GCFTR fuel cycle scenarios that have a deep-burn (>90% burnup of the TRU fuel) primary objective and a secondary objective of avoiding reprocessing of the TRU fuel if possible.
