    摘要: NDE probes provide unique data signals from a remote object such that can be used to accurately and precisely locate a position. With a computer processor, the data signals are converted into a positional fingerprint that is compact and easily analyzed as a file or information of probe position. The positional fingerprint is stored in association with the position or object to verify a same position at another time. Another probe detects other data signals for the object at another time. Under a similar transformation into a positional fingerprint, the position of the other probe can be matched to the first by comparing positional fingerprints. The comparison may use a probabilistic comparison and/or compare several different fingerprints from several different locations and times to ensure a best match. Position verification between probes may ensure a repair has been completed in the proper location, verify system integrity or investigate potential problems.

    摘要: A detection system is provided for use in a high-radiation environment includes a sensor assembly with a housing enclosing an unshielded radiation-hardened sensor for generating a digital signal of detected data corresponding to an object of interest and a first serializer/deserializer (SERDES) for converting the digital signal into a serial bit stream. A high-frequency transmission cable transmits the serial bit stream to a signal processing module located outside of the high-radiation environment where a second SERDES deserializes the serial bit stream to generate a decoded signal that is processed to generate an output at a display device corresponding to the detected object.

    摘要: Vibration of a jet pump installed in a reactor pressure vessel of a boiling water reactor is monitored. Ultrasonic waves are transmitted from an ultrasonic sensor installed on an outer surface of the reactor pressure vessel toward a throat and a diffuser of the jet pump. When the ultrasonic waves reach respective outer surfaces of the throat and diffuser, reflected waves are generated at the respective outer surfaces. The ultrasonic sensor receives those reflected waves. The ultrasonic signal process section obtains a distance in the horizontal direction between the throat and the diffuser based on a time difference of the reflected waves reflected from respective reflection surfaces of the throat and diffuser and a sound speed in reactor water in the neighborhood of the throat and diffuser. A relative vibration is obtained based on the change with time of the distance.

    摘要: This invention concerns robotic systems and is specifically concerned with an improved apparatus and method for remotely positioning a sensor, such as an ultrasonic probe, in limited access areas within a nuclear reactor. The apparatus includes a bottom frame and a top cover which is substantially aligned with and positioned above the bottom frame. A sensor is connected to the top cover and linear rails are connected to the bottom frame in a parallel relationship. There is a mechanism movably connected to the first and second linear rails in order to allow horizontal travel of the top cover. Further, there is at least one cable connected to the sensor and a power source, signal source or receiver.

    摘要: The invention relates to an apparatus and methods for operation in relatively high radiation fields to remotely switch signal devices through a shared single main umbilical signal cable. The invention is particularly suitable for use in a nuclear reactor, such as a boiling water reactor, and in difficult to access areas in the reactor pressure vessel. One or more main umbilical cables connect a control station to an enclosure housing a signal switching device. The signal switching device allows several signal generating/receiving devices, such as cameras and ultrasonic probes, to be controlled by the one or more main umbilical cables.

    摘要: A fixture for performing visual inspections of the underside of the top guide of a boiling water reactor. The inspections are performed in the reactor vessel, under water, and includes a framed structure that rests on top of the top guide and supports a wheel track within a fuel assembly opening in the top guide, that follows the contour of the opening. A camera support, suspended from the frame, is then remotely, manually rotated to follow the contour of the wheel track as the fixture maintains the camera at a fixed angle and known constant distance from the underside of the top guide.
