Summary
Peaceful nuclear explosives have been suggested for use in various excavation projects. A proposed treaty would limit the total possible yield for a single-charge and row configurations. In 1976 and 1977, Lawrence Livermore Laboratory conducted a series of single- and row-charge cratering experiments for possible application in various excavation projects. The report describes a selected number of those experiments, giving the onset of first motion, peak spall velocity, onset of gas acceleration, and velocity at the end of gas acceleration for the center target of each single-charge experiment and for every target in the row-charge experiments. Graphs illustrate the unsmoothed displacement of each target as a function of time. For each single-charge experiment, peak velocities are compared to crater dimensions and the charge depth that produced the highest velocity and largest crater dimension is identified. Peak velocities from the row-charge experiments are also related to charge depth and spacing to determine an optimum depth for the single charges as well as the optimum depth and spacing for the row charges that produced the highest surface velocities.
