Description of methodology of conservative RIA analysis with use of spatial kinetic reactor core model is presented. It is shown that their application yields more conservative assessment of reactor core parameters for which acceptance criteria for rod ejection RIA are established, in comparison with point-one-dimensional kinetic model.
