This book was released on 1959. Available in PDF, EPUB and Kindle. Book excerpt: The results of temperature measuring experiments conducted for Rainier shot, Operational Plumbbob are described. The temperature distribution in the surrounding tuff resulting from the detonation of an underground nuclear device yielding 1.7 kilotons of energy has been measured. Data indicate peak temperatures in the vicinity of 90 C existing in the central regions which drop rapidly to approach ambient temperatures at distances of about 180 feet from the original ground zero. Based on measurements taken in three holes drilled into the central regions, contours of constant temperature are constructed. The temperature picture is consistent with the consideration that most of the heat entered the water contained originally in the tuff and the unconsolidated material which filled the cavity after its initial collapse. The amount of energy contained in the central regions in the form of tuff heated to below 90 C is roughly estimated to be greater than one-half of the total energy release. An unsuccessful attempt to measure the temperature rise across the shock front of the pressure wave produced by the detonation is described, and reasons for failure are discussed. (Author).
