This report is a summary of the aerothermodynamic calculations that have been made during the evaluation of the Tory II-A reactor. A presentation is made of the computational techniques developed, the materials properties utilized, and the calculational results obtained. In addition, relations fundamental to the analysis are discussed

In the course of the cratering studies conducted as part of the Plowshare Program, the dependence of crater dimensions on depth of burst and the scaling laws relating crater dimensions to total energy release have been derived for chemical explosions in the desert alluvium of the Nevada Test Site. The desert alluvium is a lightly cemented sand and gravel, which was chosen for study because the first nuclear cratering explosions were fired in the medium and it was of interest to compare the nuclear and chemical explosion in the same medium. Shoemaker of the U.S. Geological Survey recently completed a detailed analysis of the Arizona Meteorite Crater and, through direct comparison with the nuclear explosion results in Nevada, arrived at an effective depth burst for the meteorite. He also reconstructed the original size and shape of the crater, and determined the limit of brecciation.
