Issues pertinent to sealing of radioactive waste repositories in bedded salt formations
Several issues have been identified as pertinent to sealing of radioactive waste repositories in bedded salt formations. These issues include: overall seal system functions and strategy for waste isolation; performance requirements for the seal system; 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 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 derives from experience with bedded salt, it has applicability to domal salt as well.
