摘要： A method and apparatus is provided for inspecting a series of obstructed welds, such as those used in attaching the jet pump diffuser to a baffle plate using a jet pump adapter within a boiling water nuclear reactor (BWR). The apparatus comprises a support, a frame with holding mechanisms, a connector, a carrier and a sensor assembly and the method can comprise positioning the apparatus so that it partially surrounds the jet pump near the baffle plate attachment region and is temporarily held in place. The sensor assembly then positions a sensor adjacent an area of interest and the carrier is rotated along the frame to scan the sensor along the surface being inspected to acquire data regarding the quality or nature of the material, such as the quality of a weld.
摘要翻译：提供了一种方法和装置，用于检查一系列阻塞的焊缝，例如用于使用沸水核反应堆（BWR）内的喷射泵适配器将喷射泵扩散器附接到挡板上的焊缝。该装置包括支撑件，具有保持机构的框架，连接器，托架和传感器组件，并且该方法可以包括定位设备，使得其部分地围绕挡板附接区域附近的喷射泵，并暂时保持就位。传感器组件然后将传感器定位在感兴趣区域附近，并且载体沿着框架旋转以沿着被检查的表面扫描传感器以获取关于材料的质量或性质的数据，例如焊缝的质量。

摘要： A method of inspecting or utilizing tools in the underwater environment of a nuclear reactor vessel, a spent fuel pool or equipment pit includes floating a platform for transporting inspection devices and/or tools over an underwater target site and deploying the devices or tools to the underwater target site. The platform may be coupled to a boom whose opposite end is carried by a cart movable about a floor area surrounding the pool. Alternatively, the platform may be independently movable along the water surface by thrusters.

摘要： Methods and apparatus for examining a nuclear reactor shroud are described. In one embodiment the inspection apparatus includes a scanner subassembly movably coupled to a base subassembly. The base subassembly includes a linear bearing attached to a first end of the base assembly and positioned to extend from the top to the bottom of the base assembly. At least one jacking cylinder is coupled to the second end of the base assembly. The scanner subassembly includes a mounting member movably coupled to the linear bearing, a rotating member pivotally coupled to the mounting member, an elongate radial bearing coupled to the mounting member, and a carriage assembly movably coupled to the radial bearing. The carriage assembly includes a scanner arm, and the scanner arm includes an inspection probe coupled to each end of the arm. The scanner arm is configured to be parallel to the radial bearing.
