Monitoring system for nuclear power plant equipments

Purpose: To facilitate abnormality detection for nuclear power plant equipments consisting of complicated redundancy systems. Method: Operation states for each of the system equipments confirmed as the result of field patrol are marked in cards and inputted into a computer with a marked card reader. The inputted data are compared with the operation states for each of the equipments during normal operation which have been previously stored in the computer, whereby the normality and the abnormality in the operation states for each of the equipments are judged. If there is any equipment in the abnormal states, the information is typewritten. (Furukawa, Y.)
