摘要： An inspection apparatus is suspended from a robotic positioning arm and is operable to inspect the surface of a boiling water reactor core shroud. The apparatus includes an attachment bracket connected to the robotic positioning arm. A guide is connected to the attachment bracket and receives an arcuate rail having a first end portion and an opposite second end portion. A motor assembly drives the rail within the guide to position the rail at a desired location along the core shroud surface relating to the guide. The rail carries a transducer assembly which is moved along the rail by a chain and sprocket assembly. As the motor assembly drives the rail, the chain and sprocket assembly simultaneously moves the transducer assembly along the rail to inspect the core shroud surface.

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 system for mapping absolute acoustic noise intensity in a three-dimensional acoustic noise field, and using three-dimensional absolute noise intensities to infer operational or performance characteristics of components or structures within the monitored field. Localized noise sources are extracted using a distant array of transducers, and the absolute intensity can be measured even when totally masked by background noise at the transducer locations. The system includes an integrated sensor installation; a neural network detection system algorithm; a zoom system to precisely examine a small region in the steam generator vessel; a fuzzy logic system detection algorithm; and an expert detection system. The signal processing subsystem operates at three different levels of detection. At the top level of detection a trained neural network system monitors the vessel length for any indication of a leak. The proposed approach uses discriminators which do not require any beamforming of the sensor signals. The presence of a leak and the general location in the vessel is determined using a fuzzy logic expert system. The leak indications are passed to a second level of detection: a beamformed system which will monitor the indicated portion of the vessel. A third level of detection systematically monitors the tagged locations to determine if a leak is really present, remaining on the specific locations to detect a leak above the defined threshold to a high degree of accuracy. The actions to be taken will be controlled by a second fuzzy logic expert interface controller.
