Thermal and mechanical codes first benchmark exercise: Part 1, Thermal analysis; Yucca Mountain Project

Technical Report ·
OSTI ID:137802

Thermal and mechanical models for intact and jointed rock mass behavior are being developed, verified, and validated at Sandia National Laboratories for the Yucca Mountain Project. Benchmarking is an essential part of this effort and is the primary tool used to demonstrate verification of engineering software used to solve thermomechanical problems. This report presents the results of the first phase of the first thermomechanical benchmark exercise. In the first phase of this exercise, three finite element codes for nonlinear heat conduction and one coupled thermoelastic boundary element code were used to solve the thermal portion of the benchmark problem. The codes used by the participants in this study were DOT, COYOTE, SPECTROM-41, and HEFF. The problem solved by each code was a two-dimensional idealization of a series of drifts whose dimensions approximate those of the underground layout in the conceptual design of a prospective repository for high-level radioactive waste at Yucca Mountain. 20 refs., 50 figs., 3 tabs.
