Drift Collapse Weight and Thermal Loading of TAD and 5-DHLW/DOE SNF Short Co-Disposal Waste Packages

The purpose of this calculation is to determine the structural response of the Transportation, Aging, Disposal (TAD) waste package (WP) and the 5-Defense High-Level Radioactive Waste/Department of Energy Spent Nuclear Fuel Short (5-DHLW/DOE SNF Short) co-disposal WP with emplacement pallet (EP) at room temperature and elevated temperatures for the complete drift collapse event sequence. the repository emplacement drift (RED) collapse will impose a pressure load due to the weight of the rubble rock and thermal expansion due to temperature rise as a result of lack of ventilation. The scope of this calculation is limited to reporting the calculated stress results in terms of the maximum stress intensity of the WP outer corrosion barrier and deformation of the outer corrosion barrier.
