Instruments for detecting leakage of steam into sodium were in operation on the Sodium Components Test Installation (SCTI) at the Liquid Metal Engineering Center (LMEC) during a 17-month performance test of the Atomics International Modular Steam Generator (MSG). No leaks occurred in the MSG, but leaks were simulated by controlled injections of hydrogen and steam into the sodium to measure the effectiveness of the detectors. Two short periods of injection tests were fitted into the MSG test schedule. Three hydrogen and 29 steam injections were made into the MSG sodium inlet line in the first period. Eighteen hydrogen injections were made directly into the MSG near the top and bottom tubesheets in the second period. The results of these injection tests are presented. The SCTI leak detection system consisted of two ANL hydrogen detectors and two Westinghouse oxygen meters in the sodium and a gas chromatograph monitoring hydrogen in the cover gas. (auth)
