Instrumentation Requirements for Geologic Repository Sealing Systems

Schematic designs have been developed for shaft, tunnel and borehole seals for a HLW repository in bedded salt. General instrumentation requirements for penetration sealing are related to repository development schedules, to the types of test for which instruments are required, to preliminary test concepts, and to the various factors which must be taken into account in evaluating instruments. In developing instrumentation specifications emphasis will be given to methods used for investigating the nature of the disturbed zone created by excavation of a penetration, and to instruments required for in situ testing of seal components.
