|Abstract:|| Since the 1960s, the Limited Test Ban Treaty has prevented atmospheric nuclear explosion testing. The nuclear thermal pulse can only be observed in atmospheric detonations. Lawrence Livermore National Lab (LLNL) started a film digitization project with the goal of digitizing all archived nuclear test films. The digitized films are highly detailed copies of the original films which can now be analyzed using modern technologies. This research involved the analysis of 7 atmospheric test shots.
During this research, timing functions for 23 test films were derived and documented. A method of thermal pulse data extraction and analysis was developed and quantitatively justified. The method was used to analyze 23 digitized test films covering 7 different test shots. The extracted pulse data was compared to thermal measurement data and prediction models presented by Glasstone and Dolan (1977). The shape of each thermal pulse was quantified using a shaping factor which was then shown to have a linear relationship to the detonation mass to yield ratio.
