  • Method and equipment for detecting deflective nuclear fuel rods
    Patent number: 3945245
    Abstract: Nuclear fuel rod ends of water-cooled reactor fuel rods, are heated in the region of the fission gas plenums and/or in the region of the upper or lower ends of the fuel columns. The moisture present in the case of damage to the fuel rods' casings, evaporates and is partly condensed at the end caps. In the case of a fuel rod completely filled with water, steam bubbles are generated. Both indications of casing leakage or damage are ascertained by ultrasonic reflection measurements and/or measurement of a temperature-vs-time curve, obtained at the end cap.
