The article presents the results of studies on the kinetics of hydrogen generation by heterogeneous compositions with aluminum exposed to γ-irradiation in air, various aqueous solutions at room temperature and high temperature annealing. It is established that the kinetics of hydrogen generation depends on the dose of γ-irradiation, temperature and composition of the aqueous medium. Changes in hydrogen generation kinetics are due to transformations of aluminium oxide coatings induced by factors simulating the NPP conditions. The effect of metal oxide coating transformations should be considered in predicting the corrosion resistance of NPP structural materials.
The studied kinetics of hydrogen generation by compositions with aluminum has shown that a kinetic method allows valuable information to be obtained on chemical transformations of aluminum oxide coatings under the action of factors simulating the PWR core. Being exposed to radiation, high temperature, aqueous medium radiolysis products and oxygen, aluminum oxide coatings undergo transformations which result in violations of aluminum oxide film integrity. Water molecules, the exothermal reactions of which lead to aluminum corrosion with the formation of molecular hydrogen and solid products, diffuse to the formed “pure” metal areas through structural coating defects. The mechanism of hydrogen and solid product contribution to oxide coating destruction of aluminum is being studied.
