摘要：

The problem of detecting in-sodium water leaks in the steam generator of liquid metal fast breeder reactor has been studied by applying the Twice-Squaring method, originally developed for acoustic detection of sodium boiling. Through the performance tests using test data synthesized by mixing experimental leak noise with background noise from real steam generators, it was concluded that the present method can detect the leak noise with signal-to-noise ratio down to -20 dB.
