OSTI ID:4387511
A method is presented for locating a tube with a leak among heat exchanger tubes in which the primary fluid is sodium and the secondary fluid is steam or a liquid--steam mixture. The process is particularly suited for the location of microleaks. The technique used consists of detecting hydrogen in the sodium by diffusing this hydrogen across a membrane associated with a mass spectrometer. Improvements made to the initial method enable the bundle of tubes containing the leaking tube to be located with the hydrogen detection apparatus. (FR)
