Issues pertinent to sealing of radioactive waste repositories in bedded salt formations
Issues that have been identified as pertinent to sealing of radioactive waste repositories in bedded salt formations include: overall seal system functions and strategy for waste isolation; performance requirements for the seal system; the need for redundancy; locations of long-term seals in excavations and boreholes; requirements for sealing interbeds and the disturbed rock zone (DRZ) seal stability for the required lifetime; and the need for short-term seals in addition to long-term seals. These issues are defined in general terms, and some principles that may be useful in addressing them are presented. Although this presentation was derived from experience with bedded salt, it has applicability to domal salt as well.
