Exploitation limits and safety operation limits for initial compact loading of the WWR-K research reactor core

Analysis of initial compact loading of the WWR-K reactor is carried out. It is defined, that reactor reactivity supply should not exceed of 5,24 % (ΔK/K) under calculated efficiencies values of reactor control and protection control systems units in operation cycle start. Value of reactivity supply one should be corrected with taking into account real values of protection control system units efficiencies. Values of normal operation limits are defined by reactor power level in dependence of water expense in first contour and water temperature on entrance of reactor core. Values of reactor operation limits norms are chosen by reactor power (precautionary signalling (PS) setting). The PS setting of reactor core for thermo-hydraulic parameters monitoring is chosen as well
