Summary

A comparison of simulation results on the accelerated unit unloading mode at VVER-1000, received in recent years, several research centers, with the results of experimental measurements. The influence of the important initial and boundary conditions for computational models, and determine the conditions obtaining conservative estimates in the analysis of security incidents on the reactivity of VVER-1000. Are considered deviations from the regulatory and technical requirements the question of the signal for an emergency protection reactivity accidents in the VVER-1000.

Keywords: neutron flux monitoring system, reactivity, reactivity coefficients, the period of the reactor. emergency protection, accelerated unit unloading, VVER, control rods of reactor protection system.
