Thermodynamic features of corrosion processes in liquid lead coolant in the presence of dissolved oxygen

In this work, the thermodynamic formalism of the law of acting masses is used to analyze the chemical equilibrium in a lead-based liquid metal solution in the case when iron and oxygen are present in the melt as impurities. The calculations were carried out using iron as an example, since it is this chemical element that is the main component of steels, which are currently regarded as the most promising container material for lead liquid-metal systems. The technology for controlling oxygen activity comes down to the fact that while maintaining the required oxygen concentration, lead becomes less chemically aggressive towards iron. By ensuring the constant required amount of oxygen in the liquid lead coolant, it is possible to maintain the basis of protective films on the surface of steel, which include iron and chromium oxides.
