Abstract

The purpose of the “Thermal Transport Evaluations Related to Waste Package Design” Task # 19 of Cooperative Agreement Number DE-FC28-98NV12081 was to develop a new CFDHT model for heat transfer and fluid flow in the potential rsepository at the Yucca Mountain, Nevada and to study the effects of forced convection during the pre-closure period and natural convection during the postclosure period. The analysis was performed for the drift dimensions shown in Figure 4-1 below. The intended use of the model is to estimate the velocity and temperature distribution as well as the highest temperature in the drift during the pre-closure and post-closure periods. The validation of the model is documented in section 6 of this report. The analysis was performed using both STAR-CD v. 3.150 and CFDHT v. 1.0, which are qualified software. The final result is the maximum temperature value in the drift during the pre-closure and post-closure period and the velocity and temperature distribution around the canisters.
