摘要： An ultrasonic testing system can receive data from at least two ultrasonic transducers and process the data in parallel to each other. The testing system can compress the data by a fixed ratio by storing the value of the sample having the highest amplitude out of a group of samples. The testing system can also provide threshold-based run-length encoding by compressing data by only storing samples which exceed a user-defined threshold value as well as a user-defined range of samples surrounding said samples. The ultrasonic testing system also provides a hardware gate for storing a peak amplitude and associated time-of-flight for a user-defined interval and a gate for storing the time-of-flight for the first excursion of the data through a user-defined threshold and interval. The operation of these gates or the storage of waveform data may be delayed by a constant delay or until the data exceeds a user-selectable threshold during a user-selectable time interval. The system also provides a multi-channel design allowing simultaneous waveform and/or hardware gate acquisition of data on more than one channel and permitting the parallel processing of data.

摘要： The present invention is directed to a sootblower (10) and particularly to a hub (80) and drive assembly (90) therefore capable of producing improved cleaning by directing the blowing medium over substantially all of the surface to be cleaned. A sootblower (10) in accord with the present invention includes a hub (80) and drive assembly (90) for converting the alternating, clockwise and counter-clockwise rotary output of a reversible drive motor (60) to uni-directional rotary movement of the sootblower lance (30). Further, the sootblower (10) of the present invention provides an incremental degree of lost rotational movement each time the direction of longitudinal movement of the lance (30) and nozzle assembly changes. Thus, the sootblower (10) of the present invention moves the cleaning nozzles (40) through different helical paths as the lance (30) moves in the forward and reverse directions to provide a plurality of crossed helical paths as the drive assembly (90) steps around the hub (80) to produce substantially full coverage cleaning of the surfaces of adjacent heat exchanger tubes.

摘要： Disclosed is a method for reducing embrittlement of certain materials of pressurized water reactor vessels caused by neutron flux. According to this method, "shadow shielding" (44) is placed within the core support barrel (2) in areas having a more benign flow environment than that of the downcomer area. This shadow shielding provides an increased neutron scattering cross section. In one example, the shadow shielding replaces segments of the core shroud plate in a manner which does not interfere with coolant flow in the vessel. The segments of the shroud plate which are replaced are those near critical regions of the vessel, typically welds (42). The size and shape of the shielding is determined according to plant specific requirements.

摘要： A method for detecting changes in the rate of heat transfer through a tube wall due to the deposition or removal of deposits formed thereon. The method involves obtaining a segment of tubing, placing a highly conductive material in contact with one of the inner surface and outer surface of the tubing wall, contacting the other of the inner and outer surface of the tubing wall with a heating or cooling medium, and measuring the time required for the temperature of the thermally conductive material to change between two predetermined temperature measurement points. Subsequently, the wall of the tubing segment is cleaned or the tubing segment is replaced with a different tubing segment, and the rate of temperature change of the tube walls is tested again in a similar manner. By comparing the times measured in the first and second trials, the difference in the rate of heat transfer before and after cleaning of the tubing segment can be determined.
