Leakage of water into sodium in a Liquid Metal Fast Breeder Reactor (LMFBR) steam generator can rapidly lead to multi-tube failures, with serious economic losses, unless early correct actions are taken. The General Electric Advanced Acoustic Detection (GAAD) system was developed to provide this early warning of leakage. It also provides location of the leak. Part I of this report describes a successful demonstration test in the Prototype Steam Generator installed in the Sodium Components Test Installation (SCTI) at the Energy Technology Engineering Center. The demonstration test proved the General Electric Advanced Acoustic Detection (GAAD) system will detect and locate intermediate size, water-into-sodium leaks. This will be achieved within 7.5 seconds with only one false alarm in thirty years when the detection algorithm is transferred from the computer to dedicated hardware/firmware. Part II describes leak detection and alarm requirements for both chemical and acoustic detectors monitoring the prototype steam generator installed in the SCTI. Acoustic detection criteria to meet these requirements were programmed into the GAAD system, with the added requirement of a very low false alarm rate. 38 refs., 36 figs., 15 tabs.
