  • Abnormal state detecting apparatus utilizing control rod for use in nuclear reactor
    Patent number: 4066497
    Abstract: A control rod position immediately after the application of an operation common for a control rod of the nuclear reactor and a mean value of outputs of a plurality of neutron detectors near its control rod are calculated. The control rod position at the termination of a time interval required for the control rod to move a predetermined distance and the mean value of outputs of the plurality of neutron detectors near its control rod are calculated. The amount of variations in the control rod position and the mean value contribute to judgement of abnormal state at each location in the nuclear reactor.
