Slope monitoring system for nuclear power plants

摘要

Because of increases in both the intensity and frequency of localized heavy rainfalls in Korea, slope failures are frequently occurring throughout the country. Subsequently, the possibility of a slope failure at NPP has become a major concern for the nuclear power industry. KHNP (Korea Hydro & Nuclear Power Co., Ltd.) has been regularly carrying out inspections of the slopes at NPP sites. However, because most of the inspections have been performed by naked eye, inspectors cannot figure out small or invisible deformation. A new slope monitoring system, termed K-SLOPE system (KHNP SLOPE Maintenance & Management System), is developed for more systematic and quantitative measurement of slope behavior by installing a series of monitoring devices.
