Abstract
This article has developed a physical model for the generation of single vapor bubbles in separate cells of a capillary-porous coating. The individual characteristics of bubbles are important for explaining the occurrence and development of cracks, damage to parts and assemblies of power plants. Solution of problem on evaporation of a clinoid microlayer under the vapor bubble growing in cell of porous structure covering metal heating surface is used. A model has been created for the development of the vapor phase in porous structures for cooling elements of power plants, melting units, which explains the mechanism of the generation, development and death of steam bubbles. The reliability of the cooling system of power plants is determined by the combined action of capillary and mass forces.
