Abstract

The paper presents the results of numerical modeling for ballooning and burst of fuel rods claddings made of domestic and foreign alloys. The integral code SOCRAT-V1/V2 is used as a means of modeling. The uncertainty analysis of the calculation results to input uncertainties of the temperature and pressure measurements was performed. The modeling results demonstrate a good qualitative and quantitative compliance with measured times of cladding failure under partial core uncovery conditions. The results of SOCRAT-V1/V2 validation evidence on the importance of performing new experiments for domestic fuel rod cladding ballooning and burst.
