The results of near-field thermal and mechanical calculations of thermal loading schemes

PDF Version Also Available for Download.

Description

Two waste emplacement schemes,borehole and in-drift are under evaluation as potential repository drift geometries for the Yucca Mountain Site Characterization Project Calculations were performed to examinethe systems implications of various thermal loadings on the near- and far-field repository environments. Ms paper reports the results of two-dimensional finite element analyses of the near-field thermal and structural response of the potential repository. Thermal calculations were run to 1000 years and mechanical calculations were run to 75 years. the time when the drifts will be backfilled. Local areal power densities (LAPDs) of 57, 80, and 100 kW/acre were used in the calculations. Both ... continued below

Local areal power densities (LAPDs) of 57, 80, and 100 kW/acre were used in the calculations. Both emplacement schemes meet current near-field thermal performance goals for all loadings examined. The mechanical calculations predict no intact rock failure, limited joint slippage around the drifts, and closure of apertures for vertical fractures above and below the drifts.
