Multiscale thermohydrologic model sensitivity analysis/011/011/011
A multiscale, thermohydrologic (TH) modeling approach (or methodology) has been developed that integrates the results from one- dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) drift-scale models and a 3-D mountain-scale model to calculate the near-field TH variables affecting the performance of the engineered barrier system (EBS) of the potential repository at Yucca Mountain. This information is required by Total System Performance Assessment- Viability Assessment (TSPA-VA) to assess waste-package (WP) corrosion, waste-form dissolution, and radionuclide transport in the EBS. This methodology is a computationally efficient, flexible means of determining EBS TH conditions; such determination would otherwise require millions of grid blocks if a brute-force numerical model were used. The methodology determines EBS TH conditions as a function of location within the repository and WP type.
