Abstract

The results of the static calculations for the constrained core SPERT-I experiments were found to be close to the experimental data. The reactor period computed from the time dependent calculations is close to the reactor period obtained from the static calculations, but there is some discrepancy with respect to the experimental data. This discrepancy may be explained by the uncertainties in the experimental conditions. The modeling of the T-32 transient in the SPERT-III E-core was performed using the time dependent mode of Serpent2. Very good agreement was observed between the experimental data and the modeling results. The reactor period obtained from the simulations could be brought to the experimental value by small system adjustments consistent with the description of the experiment. The results of the simulations show that Serpent2 in the time dependent mode adequately models the reactor physics part of the transients performed in the SPERT-I and SPERT-III experiments.
