The aims and problems of research on the means for intensifying heat exchange in the equipment of nuclear power plants are examined: nuclear reactors, steam generators, turbine condensers, heat-exchangers of dry water cooling towers, intermediate separators-steam superheaters of turbines, heat-exchange apparatus of safety systems, turbo-electro-generators, oil coolers, feed-water heaters. Methods of identifying heat-exchange are analyzed: different types of finning, turbulence generators and swirlers of one- and two-phase flows, coating on heating surfaces, systems with mixed flow. Computational recommendations are made for determining the intensity of heat emission from promising types of heat-exchange surfaces: bundles of lowfinned tubes and spiral coils.
