Korinny A. The neutron field stability at VVER-1000 reactor core transients

The dissertation is devoted to a task of VVER-1000 nuclear reactor power distribution stability increasing during the xenon transients. Theoretical and experimental researches and tran-sients simulating neutron-physics calculations are maid. The control method based on transient optimization by the given axial offset maintenance is developed. The modifications allow to ex-pand a range of controlled condition or to minimize water changes. Within the framework of one-group «twin-points model» the theoretical substantiation of a method is developed. The model provides the ability to predict control influences at maneuvers realization quantitatively. The aspects connected with the algorithm influence on NPP energy manufacturing technological process profitability and safety are investigated.
