The best estimate thermal hydraulic codes for PWRs and BWRs accident analysis were elaborated in 80-th years. The main goal of the best estimate codes (BEC) calculations was to obtain the real picture of the reactor facilities parameters changes during transient and accident regimes. This codes were based on 5--6 equations mathematical models taking into account separate flows of water and vapor. Validation of the best estimate thermal hydraulic codes applied VVER calculations is the main objective of the article. The concept of CSNI test matrices application to the codes validation is presented. The ways of the matrices improvement for this purpose is outlined. Taking into account deficiency of the operating integral test facilities a special attention is focused on the original separate effects experimental data obtained in Ukraine and which was not included to the CSNI matrices. To facilitate application of the obtained data to the codes validation the numerical experiment method was elaborated. The example of the method application is described.
