Abstract:
According to an embodiment, core thermal limit monitoring device is provided with calculating units, and signal input processing units, synchronization processing units and signal output processing units, corresponding to the calculating units. The calculating unit determines if it is necessary to output a signal to the control unit by calculating the thermal state values of the monitoring regions based on a signal representing the state of the core. The synchronization processing unit, if it is necessary to output a signal to the control unit, transmits a signal-output stop signal to the other synchronization processing units, and otherwise, the synchronization processing unit transmits a signal-output stop cancellation signal to the other synchronization processing units. The signal output processing unit, when the synchronization processing unit does not receive a signal stop signal, outputs a signal representing the calculation results of the calculating unit to the control unit.
