technical specification monitoring system in nuclear power plant

摘要

The present invention is an operation mode for determining the operation mode of a nuclear power plant from state information of process variables including reactivity conditions, rated heat output, and average reactor coolant temperature for the operating state of a nuclear power plant. A monitoring unit, a variable calculation unit that calculates and outputs the calculated variables set from input values for the process variables of the nuclear power plant, and the temperature and pressure values to determine whether the temperature and pressure values for the set process of the nuclear power plant are located in the stable region A graph-related variable monitoring unit that outputs a graph area value for pressure, a measurement instrument monitoring unit that monitors the normal status of an instrument channel that measures a parameter to be measured in a nuclear power plant, and outputs result information of the instrument channel state, and a set operation Based on the technical guidelines, the operation restriction condition is monitored from the monitoring target information including process variables, operation mode information, calculated variables, graph area values, and instrument channel status result information, and if it is determined that the operation restriction conditions have been violated, the violated operation restriction conditions A driving restriction condition monitoring unit for outputting identification information, an alarm, a follow-up action item, and a time limit, and a follow-up action monitoring unit for monitoring whether the follow-up action item is completed within the time limit is provided.
