AbstractSearch acoustic system of the heat carrier leak in the first contour (SLHD) provides the detection of the heat carrier leak of the first contour with an expense from 3,8 l/min. Time of information delay in case of leak detection is no more than 3 minutes. The main way of increase of efficiency and reliability of system of SLHD is enhancement of leak search algorithm. Authors of article offered approaches to SLHD data processing: regulation of sensors indications, calculation sequent, majorization. In the article much attention is paid to compensation of background noise of the first contour premises and measuring path noise. Offered methods have to provide leak identification by an expense less than 3,8 l/min.
Keywordsbarriers protection of the nuclear power plant, leak detection, acoustic sensor, data regulation, method of sequent, majority function
