Abstract

The influence of ionizing radiation on interphase transport of noncondensing gases in a liquid water-vapor-gas mixture system is investigated. A mathematical model is developed and computational experiments are performed for the irradiation of water in equilibrium with vapor, in a closed vessel with a free volume in the absence of mixing of the phases and intense heat transfer, and irradiation of a moving liquid in the bubble flow regime. It is shown that when a liquid water-vapor-gas mixture two-phase system is exposed to ionizing radiation the transition of the mixture of hydrogen and oxygen from the vapor-gas phase into the liquid phase becomes more intense. The reason for this is that they undergo an effective radiation-chemical reaction in a layer adjoining the surface separating the phases. This effect is useful for developing a water-chemical regime for future and currently operating nuclear power facilities.
