Abstract
Our research is devoted to the study of the possibility of determining the parameters of leaks in the pipelines of ITER by the acoustic emission method. Research results are presented for leaks in pipelines, length from 900 mm to 150 m. Flow was carried out with steam and water through fatigue cracks in size from 5 to 39 mm in the pipelines. We investigated regularities of changes of the amplitude, temporal and spectral parameters of acoustic emission signals. The loss through flow and the distance from the source of leaks to the AE sensors were changed. Methodology was developed, which allows us to determine the coordinates and parameters of leakage through information on the AE signals.
