This paper presents arrangement of the problem, methodology of experiment performance and results of experimental investigation of coolant mixing in downcomer and lower plenum of VVER-1000. Three groups of experiments simulating coolant mixing were executed: in conditions of RCP start-up, during natural circulation recovery in the course of SB LOCA and in conditions of stable operation of different amount of RCPs. Results of experiments are used for validation of codes.

Keywords: CFD; VVER-1000
