Abstract The present invention provides a vibration monitoring apparatus that monitors vibration of a jet pump disposed in a reactor pressure vessel using ultrasonic wave, including: an ultrasonic sensor that is attached to an outside the reactor pressure vessel, and transmits and receives ultrasonic wave; a reflector that is mounted on a surface of a riser pipe of the jet pump, and includes a planar reflecting surface that can reflect ultrasonic wave; and a signal processing unit that performs signal processing of the ultrasonic wave transmitted by the ultrasonic sensor, reflected by the reflecting surface of the reflector, and received by the ultrasonic sensor, and measures a vibration amplitude of the riser pipe and calculates a vibration waveform.
