LATTICE DEFORMATION FEASIBILITY STUDY.

Abstract

Four samples of reagent grade ammonium perchlorate weighing five grams each were irradiated in the Aerojet-General Nuclear Industrial Reactor (AGNIR) for periods of 37, 78, 187 and 224 hours. Sample decompositions were found to be proportional to total radiation exposure. The crystalline samples recovered for analytical and calorimetric measurements all showed excessive radiation damage with extremely pourous structures and acidic residues. The Apparent Lattice Energy Content was determined by measurement of heat of solution before and after the radiation exposure. Comparison of measured heats of solution with estimated heats of solution based on chemical analyses of the samples indicated that the derived values of apparent lattice energy could be accounted for on the basis of changes in chemical composition alone, particularly the accumulation of free perchloric acid in the irradiated samples.
