摘要： An improved measurement apparatus employs a support that includes a housing and that further includes a follower that is movably situated on the support. The follower is biased in a direction generally away from the housing. The housing and follower are receivable between a spring/dimple pair, and a sensor detects the distance between the housing and the follower when interposed between the spring and dimple. An indicator apparatus employs the signal to output and indication that is representative of the amount of compressive loading that will be applied to a fuel rod by the spring/dimple pair, and the indication is based at least in part upon the distance between the portion of the housing that is engaged with the dimple and the portion of the follower that is engaged with the spring.

摘要： A fuel assembly inspection system that utilizes a pressure transducer mounted to a utility's spent fuel handling tool to detect a relative change in depth of a fuel assembly during fuel inspections. The system then wirelessly transmits the signal to a fuel inspection recording system, which converts the signal to a relative height along the fuel assembly being viewed by a camera, and displays the relative height along with the applicable fuel assembly feature being viewed by the camera (e.g., nozzle, grid, span) via a text overlay on the video image of the inspection.

摘要： The single rod ultrasonic leak detection tool will be used to detect leaking fuel rods by evaluation if there is water inside the rod. The test will be performed by moving one fuel rod between two ultrasonic transducer oriented in a pitch/catch configuration. The detection tool uses ultrasonic transducers as the primary method to detect leaking fuel rods. Two probes are preferably positioned near the fuel rod in a pitch/catch or transmitting/receiving configuration. One probe 36 sends the signal into the rod and the other probe of a set of probes receives the signal. An evaluation of the received signal is performed in various embodiments, to determine leak tightness of the fuel rod. In various aspects, two sets of probes may be utilized so that measurements can be taken on both sides of the fuel rod.
