Abstract
A method and apparatus for detecting the leakage of coolant into the jacket of a nuclear reactor fuel rod. The apparatus includes a coolant absorbing means mounted at a predetermined location within the jacket. Upon leakage of coolant and absorption thereof pressure forces developed by the absorbing means locally deform the jacket. Periodic inspection of the jacket's exterior by gauges, optical instruments or the like, reveals the presence of such deformation thereby indicating the presence of coolant leakage.
