摘要：

Results of experimental investigations are presented of the critical heat flux in conditions of the upward water flow at a low pressure in a circular tube with the internal diameter of 11 mm and in a 19 fuel rod cluster in the WWER reactor geometry. The experiments are carried out at the output pressure of 0.1-1.1 MPa, the mass flow rate of 25-500 kg/(m2&middots), the input water temperature of 9-50°C and at the input throttling up to 5 MPa. Experimental data are compared with data calculated by means of the RELAP5/mod3 code. It is found that the calculational data exceed essentially the experimental ones.
