The results of the experimental investigations of coolant mixing and departure from nucleate boiling in TVSA-T with combined spacer grids and mixing grids on aerodynamic and thermal test facilities are presented. As a result of the obtained experimental data, the determination of mixing coefficient was carried out and the CRT-1 correlation for the critical heat flux calculation was developed. The applicability of correlation for critical heat flux calculation for TVSA-T VVER-1000 was substantiated.
