The paper presents the results of qualification analysis of experimental data on high-temperature oxidation of the Russian zirconium alloys in steam, which include an assessment of the consistency of measurement results in tests, and numerical modeling of experiments with SOCRAT-V1/V2 code. Conclusions are provided on the possibility of using the SSC RIAR experimental programs for validation of severe accident codes, and the applicability of the SOCRAT-V1/V2 code for prediction of the high-temperature oxidation of the Russian zirconium claddings of fuel rods.
