Remaining Useful Life Estimation of Electric Cables in Nuclear Power Plants

摘要

Electric cables help form the backbone of instrumentation and control (I&C) systems in nuclear power plants by providing power to electrical equipment and transmission paths for instrumentation signals used to perform safety functions and control plant operation. Operating experience in the existing fleet of nuclear reactors has shown that the number of cable failures increases with plant age resulting in plant transients, shutdowns, and in some cases, the loss of safety functions. As a result, cable condition monitoring and remaining useful life (RUL) estimation have become increasingly important in recent years, especially as many plants begin operation beyond their original licensing periods.
