Abstract: 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.

Abstract: 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.

Abstract: 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.
