The work out methodic of calculation of cofficient heat-return for region non-balance boilung for hressure in contour 16MPa; the methodic of experiment investigation heat-transfer in condition breaks of circulation heat-carrier are present. At the same time lowering pressure and expenditure with vibration power may be most danger. It was established that the temperature membrane fuel elements in the boiling increases linearly with increasing heat flux, unssteadiness load does not change the time of the crisis of heat transfer and the critical heat flux, the development of the crisis begins with the apperance of instability temperature envelopez; instability costs may not cause instability in wall temperature pre-crisis mode. It is shown that the greatest danger may make a simultaneous decrease in pressure and flow fluctuations in power. Product Description popup.authors Авраменко А.О. Антіпов В.Г. Волошина И.В.
