“…This expression is a modified form of a closed-form solution of Chabannes (1982) for secondary creep closure of an infinitely long cylinder in an infinite medium. The stress exponent for secondary creep of WIPP rock salt has been found to be near 5 (e.g., Munson et al, 1989). Because tile closure rate is a run,Lion of the test interval pressure, the closure rate will b, time-dependent.…”

“…The base idealized stratigraphy for the WIPP underground used in the geomechanical model is the stratigraphy as defined by Munson et al (1989). This stratigraphy is shown in Figure 4 with the disposal room located at the original horizon.…”

“…A multi-mechanism deformation (M-D) model proposed by Munson and Dawson (1979, 1982, 1984 and extended by Munson et al (1989), has been included in SANTOS to model the creep behavior of rock salt. This model was used for the clean and argillaceous salt.…”

This report summarizes a series of structural calculations that examine effects of raising the Waste Isolation Pilot Plant repository horizon from the original design level upward 2.43 meters. These calculations allow evaluation of various features incorporated in conceptual models used for performance assessment. Material presented in this report supports the regulatory compliance re-certification, and therefore begins by replicating the calculations used in the initial compliance certification application. Calculations are then repeated for grid changes appropriate for the new horizon raised to Clay Seam G. Results are presented in three main areas: 1. Disposal room porosity, 2. Disturbed rock zone characteristics, and 3. Anhydrite marker bed failure. No change to the porosity surface for the compliance re-certification application is necessary to account for raising the repository horizon, because the new porosity surface is essentially identical. The disturbed rock zone evolution and devolution are charted in terms of a stress invariant criterion over the regulatory period. This model shows that the damage zone does not extend upward to MB 138, but does reach MB 139 below the repository. Damaged salt would be expected to heal in nominally 100 years. The anhydrite marker beds sustain states of stress that promote failure and substantial marker bed deformation into the room assures fractured anhydrite will sustain in the proximity of the disposal rooms.
