ABSTRACT:
A system for monitoring power, particularly a power distribution, of a nuclear reactor includes a plurality of neutron flux measuring units disposed in a core of the nuclear reactor for measuring neutron flux in the core and generating neutron flux signals. A unit, generally constructed by a process computer, for calculating a neutron flux distribution in the core in response to the neutron flux detection signals from the neutron flux measuring units, is provided. A unit for calculating a higher mode of the neutron flux distribution in accordance with results of calculations performed by the neutron flux distribution calculating unit, is provided. A filter calculating unit is provided for obtaining a filter for extracting characteristics of change of the neutron flux detection signal in response to the neutron flux detection signal and an input/output unit for transmitting the neutron flux detection signal filtered by the filter obtained by the filter calculating unit.
