Abstract :
This report gives the results of a numerical simulation of the reactor´s neutron power changes process, which are caused by fixed changes of reactivity. We make a comparison of the reactor power changes when changes of reactivity were the same but in the active core different types of fuel were replaced. The cases of standard UO2 fuel using mixed (Th,U)O2 fuel was examined
