摘要：
The main technical decisions adopted in developing a moisture-content system for monitoring leaks in the pipeline of the first loop of VVÉR are examined taking account of experience and the main requirements for systems monitoring leaks in pipelines in nuclear power plants. The results of a computational and experimental validation of the serviceability of the diagnostics algorithm and the characteristics of the moisture-content system for monitoring leaks are presented. Using the Kupol-M computer code and a thermophysical stand simulating a leak in a pipeline with basaltic thermal insulation mats in the No. 3 unit of the Kalinin nuclear power plant, it is shown that the system meets the main requirements of the modern concept of leak before rupture.
