ABSTRACT:
A nuclear reactor comprising a reactor vessel, a core housed in the reactor vessel, an ultrasonic transducer mounted in the vicinity of the upper end of the core for emitting and receiving an ultrasonic wave pulse signal propagating above the core, means for rotating the transducer by a prescribed angle to scan horizontally the ultrasonic wave emitted from the transducer, a plurality of reflective means mounted in the vicinity of the upper end of the core in a manner to face the transducer for reflecting the ultrasonic wave signal emitted from the transducer, means for energizing the transducer, and means for displaying the ultrasonic wave signal reflected by the reflective members and received by the transducer in synchronism with the wave scanning motion of the transducer, wherein each reflective member comprises reflective surfaces each capable of reflecting the incident ultrasonic wave signal in a direction parallel with the incident direction and is mounted such that the distances of the reflective surfaces from the transducer are different enough from each other to prevent interference among the reflected ultrasonic wave signals.
