TH27 Effects of Long-Term Operation on Electrical Cable Aging, Condition Monitoring, And Performance Reliability

As nuclear plants approach the 40 to 60 year period of extended operation and some consider the option of a subsequent license renewal (SLR) period beyond 60 years, reliability, performance, and condition monitoring of existing electrical cabling are a focus of attention by industry and regulators. Cable aging management programs adopted for license renewal rely on operating experience, inspections, testing and condition monitoring for reasonable assurance of safe operations. This session will provide the status of current regulatory approaches, known aging effects, and research activities by government and industry organizations. Attendees will receive the latest available information regarding technical and regulatory considerations surrounding cable aging, environmental qualifications (EQ), and reliability during a SLR period of operation.
