Abstract :
It is one of main measures for safe operation of the fast reactor to use acoustic leak detecting technology to realize early detection for water/steam leak of steam generator in fast reactor nuclear power station. Based on experimental data about sodium loop experiment completed by Liquid Metal Laboratory of Tsinghua University, this paper investigates the application of wavelet noise elimination in detection for water/steam leak of fast reactor steam generator. The result shows that wavelet noise elimination can greatly improve signal-noise ratio, and it is really a highly effective method for timely and correct leak detection of the steam generator
