Ovdiienko I. Safety Assessment of VVER-1000 in transients and reactivity accident with use of spatial kinetic model

The dissertation is devoted to substantiation of safety WWER-1000 in reactivity initiated accidents, power maneuvering modes and transients with violation of normal conditions of the operation that characterized by asymmetrical behavior of reactor core, with use of spatial kinetic model. The technique of carrying-out of the conservative safety analysis for research reactivity initiated accidents with use of spatial kinetic reactor model is improved. On the basis of the developed spatial reactor core model the safety analysis WWER-1000 in the conditions of deviation of reactor core characteristics from design values and in power maneuvering mode is made.
