Ignat'ev, D. Soldatkin, A. Mokrushin, L. Loshmanov, A. Kostyukhina] A procedure is developed for performing on the PARAMETR stand integrated tests on VVER fuel-element simulators under conditions of the first stage of LOCA. The computational and methodological underpinnings of the experiments make it possible to conduct investigations under pre-determined conditions. The experiments showed the effect of the combinations of temperature-force conditions (factors) of the first stage of the accident on the thermomechanical behavior of fuel-element cladding made of E-110 alloy. The cladding material undergoes a martensite transformation with grain growth. Hardening of the experimental cladding material with a significant reduction of plasticity is noted. The results of the investigations can be used to predict the thermomechanical and corrosion behavior of cladding at the first and second stages of the accident as well as for adjusting the number of depressurized fuel elements in the accident.
