Zusammenfassung:An inspection method and apparatus for testing nuclear fuel rods for helium leaks by constantly leaking helium at a known predetermined value into a test chamber (16) containing the fuel rod or rods (R) to be tested, and measuring the helium in the atmosphere within the chamber such that a measured helium value below a preset minimum indicates an equipment malfunction, whereas a measured helium value above a preset maximum indicates the presence, and a measured helium value between the preset minimum and maximum indicates the absence, of a helium leak from the fuel rod(s) under test.
