Essay

. Dissertation is devoted to developing new technology in detecting ogermethical shells of fuel rods by acoustical method, elaborating a model of installation and testing it in real conditions of NPP. The mathematical model, which can describe the process of acoustic vibration whit gaz stream that runs out into liquid is roposed. Moсkup tests with NPP specifications showed that effective signal level greater than production noise in 7 - 8 rank. New leak detection system faster then traditional system on 2 hours on one fuel assmebly.
