Abstract:
1. A nuclear reactor vibration surveillance system comprising: a first ultrasonic transducer for transmission which is arranged on the outer surface of a reactor pressure vessel and is configured to convert a transmission signal into an ultrasonic pulse signal and allow the ultrasonic pulse to be transmitted to a reactor internal component; an ultrasonic transmitter which is electrically connected to the first ultrasonic transducer and is configured to transmit the transmission signal; a second ultrasonic transducer for reception which is arranged separately from the first ultrasonic transducer on the outer surface of the reactor pressure vessel and is configured to receive a reflected ultrasonic pulse, which is transmitted by the first ultrasonic transducer and reflected by the reactor internal component, and to convert the received reflected ultrasonic pulse into a reception signal; an ultrasonic receiver which is electrically connected to the second ultrasonic transducer and is configured to receive the reception signal; a signal processor which is electrically connected to the ultrasonic transmitter and ultrasonic receiver and is configured to input a signal to the ultrasonic transmitter and receive a signal from the ultrasonic receiver so as to apply signal processing to the signal; and a display unit which is configured to display vibration information of the reactor internal component obtained as a result of the signal processing by the signal processor.
