AbstractIn this paper we present the results of numerical studies of control algorithms for the spatial distribution of the neutron field in the reactor core of WWER-1200 in the implementation of daily maneuvering regimes at NPPs with WWER-1200. The possibility of automated control of axial offset is demonstrated using one of the control groups with the aim of removing the psychological stress on operational personnel at nuclear power plants in maneuvering regimes. At the same time there is an additional minimization of water exchange while saving all nuclear safety parameters in the reactor core. The research is carried out on the basis of the PROSTOR software complex, which currently used in the Novo-Voronezh NPP to conduct training sessions with operational personnel of nuclear power plants and their training in optimal control algorithms for the power unit in maneuvering regimes. The methodology of adjustment of parameters of offset regulation depending on the neutron-physical characteristics of the core is proposed. The relevance of the conducted researches is related to the fact that for the NNPP-2 and LNPP-2 according to the NPP-2006 project in Russia it is planned to test the daily operating modes of the NPP with the power maneuvering in a wide range of their values. Verification of the operation of power units in such modes and their reliability will improve the competitive ability of NPP equipment with WWER abroad.
