Management of axial offset of a nuclear reactor when maneuvering by power

High reliability and security of power unit are basic requirements in the maneuvering mode operation of the power unit. Guarantee of safe and reliable operation of power unit is the reactor stability in case of disturbances in steady load and maneuvering load. A quantitative measure of the reactor stability is an axial offset (AO) which is uniformity technological characteristic of energy release, therefore efficiency measure of WWER-1000 operation is to minimize the deviation of the AO. Influence on axial offset of the automated control systems by capacity of the power unit in the maneuverable mode is investigated. The compromise-combined control program of power unit is considered, which maintains constant AO value in case of switching the power unit from one power level to another.
