Abstract:

In exploring methods to maximize energy conservation for demilitarizing U.S. Navy ordnance, an in situ autoclave melting procedure was evaluated. After reviewing the literature for both theoretical and experimental investigations of thermal explosions, it was found that The literature is replete with warnings that critical temperature and time-to-explosion calculated for chemically pure explosive systems are most optimistic and a resume of some of these warnings is warranted again here. Earlier hazard analysis evaluations of the autoclaving process by other investigators were overly optimistic because of simplifying assumptions. Prolonged heating andor holding of melt-cast explosives, even at temperatures within established specified limits, may well lead to accelerating decompositions and fires if not to high order detonations. Further studies should be carried out to determine whether or not consecutive meltings and coolings of a given explosive can be carried out with impunity without some purification between each melting.
