Nonequilibrium pressurizer model

This paper describes the development of the nonequilibrium model for the prediction of pressurizer pressure behaviour. Due to the disturbances in the pressurizer, the liquid and vapour depart from the equilibrium states, so that the phase transition takes place at the liquid - vapour interfaces. The law of the phase transition intensity is formulated from the kinetic theory viewpoint, in which the potential of local nonequilibrium and value and efficiencies of the interface surface are expressed by phase bulk temperature, and by the proposed process coefficient
