  • Patent number: 4994232
    Abstract: A method of inspecting the quality of both ends of nuclear fuel rods and which includes a housing with longitudinally separated slots for receiving X-rays downwardly therethrough to define first and second operating positions so that the forward ends of nuclear fuel rods can be aligned below the first operating position and the rear ends of nuclear fuel rods can be aligned below the second operating position. An endless conveyor belt system, having at least three longitudinally spaced apart cleats mounted thereon to define first and second film cartridge receptacles, is adapted to advance X-ray film cartridges longitudinally through the housing. A table is included for selectively lifting the film cartridges from the belt system to maintain the film cartridges stationary while the conveyor belt system is advanced.
