Abstract
Provide a nuclear reactor power monitoring technology for enhancing the monitoring accuracy and reliability in nuclear thermal hydraulic stability. A power monitorincludes a first calculation unitconfigured to calculate a first stability index based on time series data indicating power oscillation in nuclear instrumentation signals outputted from a plurality of nuclear instrumentation detectors; a first determination unitconfigured to compare the first stability index and a first reference value and determine whether nuclear thermal hydraulic stability of the reactor core is stable or deteriorated; a second calculation unitconfigured to calculate a second stability index of the reactor core based on the time series data when the deteriorated state is determined in the first determination unit; and a second determination unitconfigured to compare the second stability index and a second reference value and determine whether to perform suppressing operation of the power oscillation.
