The task of hydrodynamics and heat and mass transfer in VVER spent fuel pool (SFP) during accident with loss of SFP cooling was considered. On the base of comparison of the local (OKB GIDROPRESS test facility, 1993 year) and integral (ALADIN test facility, 2016 year) experiments results and calculation results (using existing steam-water mixture void fraction correlations), the most suitable correlations were selected. 16 correlations were analyzed. Analysis shows, that 2 correlations are the most suitable for SFP conditions. That is Avdeev A.A. and Stiricovich M.A. – Kutateladze S.S. correlations. Calculation was performed, using ROK/B code.
