Abstract:

Mechanisms controlling the hydrologic response of a deep based system to nuclear attack are identified through an analysis of data from underground tunnel complexes at the Nevada Test Site. Two mechanisms are identified, inflow of fracture water mobilized by the dynamic loadings and inflow of pore water due to explosion generated residual stresses and pore pressures. Both mechanisms are serious potential threats to deep based systems located in geologies similar to Generic Mountain C. The magnitude of the fracture water threat is impossible to assess due to nonavailability of sufficient geologic and hydrologic data at Mountain C. The magnitude of the pore water threat at site C is estimated based on flow calculations using the one dimensional axisymmetric code CONSL. Calculations indicate that pore water flow at the Generic Mountain C site will be orders of magnitude greater than similar flow at the Nevada Test Site because of the much more permeable rock at Mountain C. The need for more refined calculations of the Mountain C response is emphasized.
