Time-dependent nuclide transport through backfill into a fracture

; ; ;
Fractures (fissures) in the emplacement rock of a geological repository of nuclear waste may intersect boreholes for waste packages, providing conductive pathways for hydrogeological transport of radionuclides. A previous study of transport through backfill into a fissure considered only steady-state transport of a stable species. The US regulatory framework for geological disposal is for much shorter time scales and requires calculation of time-dependent radionuclide transport into fractures. In this paper a transient analysis is presented of radionuclide transport through backfill into a fissure.
