Verification of the TECh'-M-97 program on the basis of experimental results obtained for a large leak on a large-scale stand with nuclear heating

Post-test calculations of the LOFT L2-5 experiment were performed as part of the international program BEMUSE using the TECh'-M-97 thermohydraulic computer code. The computational results were used to determine the parameters characterizing the quality of the the nodalization scheme developed and the stationary state obtained. The sensitivity of the computational results to a change in the basic initial data was estimated. Good agreement was obtained between the computational and experimental results on the temperature regime of the fuel elements during an accident.[PUBLICATION ABSTRACT]
