Title: Numerical simulation of reactivity measurements in WER-1000 reactor

Abstract

Reactivity is one of the most used and important concepts in physics and nuclear reactor calculations carried out for the safety analysis. Currently, design calculation of Russian WER reactors are carried out with modern coupled time-dependent neutronic and heat hydraulic codes. They allow to perform numerical simulation of reactivity measurements. However, point kinetic model used for simulation of large reactivity insertion leads to some issues. The paper discusses the numerical simulation of reactivity measurement, shows that the reactivity obtained from the steady state solution does not always correspond to the measured value. Comparison of scram system reactivity worth calculated and measured during physical start-up of unit 3, Kalinin NPP is presented. (authors)
