摘要:
A method and device to repair fuel assembly structural defects in the top nozzle to guide thimble connection. The device includes a shaft with tendons configured to defect to allow a structural connection between a dimple and a dimple area of a guide thimble.
摘要:
A device and method to move a fuel assembly of a nuclear reactor, wherein the device eliminates the potential for dropping the fuel assembly due to stress corrosion cracking of the upper guide thimble sleeves that attach the top nozzle to guide thimbles.
摘要:
An apparatus to measure external dimensions of a fuel channel of a boiling water reactor, having a rigid frame which has a lower seat to accept a nozzle of a nuclear fuel assembly, the rigid frame extending an entire length of the nuclear fuel assembly, an inspection arrangement including ultrasonic transducers placed upon the rigid frame, the ultrasonic transducers supported by the rigid frame, the ultrasonic transducers configured to generate and receive ultrasonic signals imparted into a medium and generate an electrical signal upon receipt of the ultrasonic signal, a signal processing arrangement configured to evaluate electrical signals received from the inspection arrangement, and a series of leads connected to the arrangement of ultrasonic transducers, the series of leads taking the electrical signals generated by the inspection arrangement of ultrasonic transducers and transporting the electrical signals from the ultrasonic transducers to the signal processing arrangement.

摘要:
A golf ball retriever comprises a club engaging portion 14 to enable the retriever to be secured to the butt end of a golf club and a ball receiving portion 2 capable of engaging and retaining a golf ball. The ball receiving portion comprises a pair of spaced arms which are resiliently deformable relative to one another as the retriever is pushed down onto a golf ball, such that the ball is gripped between the arms. The arms are bifurcated to form respective claws 7 terminating in pointed ends which serve to contact the dimples on the surface of the golf ball to steady and locate the ball below the retriever prior to gripping.
