Abstract: Representations about the physical mechanism of the heat transfer crisis under forced motion of two-phase flow in heated channels are considered. Analysis of known approaches is carried out and methodical bases of the development and application of recommendations on calculation and control of the heat transfer crisis at NPPs with WWER is proposed.

Keywords: water-cooled nuclear reactor, two-phase flow of coolant, heat transfer crisis.
