Abstract

The processes of corrosion and masstransfer have a significant impact on the service life, the performance of the main components and the safety of nuclear reactors with heavy liquid metal coolant. When justifying the safety of nuclear reactors with the help of design codes, it is necessary to simulate physical and chemical processes in the coolant circulation circuit, including the interaction of impurities in the coolant volume and oxidation of the structural steel surfaces.
To ensure the possibility of computational modeling, models of physical and chemical processes in the coolant and on the surfaces of steels are needed. It can be used in the design codes.
Therefore, the analysis of approaches to the modeling physical and chemical processes in nuclear reactors is very relevant.
In the article the approaches to the description of physical and chemical processes in the coolant and on the surfaces of structural steels in the circulation circuits of nuclear reactors with heavy liquid-metal coolant is analyzed.
