Abstract

The admissibility of calculational deviations in value of reactivity coefficients obtained by various calculation methods for test model of IAEA (the reactor AI-600 with a hybrid core) is analyzed. The influence of "error" of calculation of reactivity coefficients is estimated through changes of the maximal temperatures in the basic accident processes at use of various calculational sets of component of feedback reactivity. The acceptability (for the given model) widely used in Russia diffusion calculation method is demonstrated. It testifies the reli-ability of a substantiation of physical parameters of safety in a reactor AI-600 with a hybrid core.
