Effect of irradiation on the thermal stability of nitric acid solutions of carbohydrazide

Thermal analysis of nonirradiated and irradiated to doses of 100, 250 and 500 kGy solutions of carbohydrazide in 3 and 7 mol/L HNO3was carried out. The onset temperature, duration, and rate of the exothermic reaction were determined; the specific thermal effect of the reaction and self-heating value of the solution were calculated. Irradiation of the solution increases the onset temperature of the exothermic reaction and reduces its specific heat release. At radiation dose of 500 kGy, the main characteristics decrease by 70%, which is associated with the decomposition of carbohydrazide.
