Abstract
An anomaly diagnosis system for a nuclear reactor core comprises an anomaly detecting unit incorporated into a fuel assembly of the nuclear reactor core, and a transmitter-receiver provided outside the reactor vessel, which transmits a signal by wireless to the anomaly detecting unit and receives an echo signal generated by the anomaly detecting unit by wireless. When the anomaly detecting unit detects an anomaly in the nuclear reactor core, such as an anomalous temperature rise in the fuel assembly, the mode of the echo signal deviates from a reference signal mode, and then the transmitter-receiver detects the deviation of the mode of the echo signal from the reference signal mode and gives an anomaly detection signal to a plant protection system, and thereby the nuclear reactor can be shut down without delay.
