ABSTRACT:
A leak detection system 40 particularly suited for employment in a steam generator 10 of the type that embodies at least one tube sheet 34 or 36 to which ends of a multiplicity of elongated tubular members 32 are suitably secured. The subject leak detection system 40 is operative both for purposes of detecting the occurrence of leaks in the steam generator 10 as well as for purposes of enabling a determination to be made as to the probable location of the leaks and the direction of flow of the leaking fluid. The subject leak detection system 40 includes circuit means formed in the tube sheet 34 or 36 so as to provide passages therethrough operative for effecting the interconnection of the exterior surface of the tube sheet 34 or 36 with the ends of the tubular members 32 that are retained therein, fluid filled plenum means 62, 64 operatively connected in fluid flow relation with the circuit means, and sensing means 46, 48 operatively connected to the plenum means 62, 64 for sensing the occurrence of fluid related changes in the plenum means 62, 64 and determining from the nature of such changes the existence of leaks in the steam generator 10 as well as the probable location of such leaks and the direction of the leakage path that the leaking fluid will follow.
