Cable Condition Monitoring Experiences at Nuclear Power Plants

| 2025:1124 | Konsta Sipilä, Anna Bondeson
Nuclear power plant cables are subjected to ageing during their service life. Proper ageing management of cables is increasingly important as the plants age and lifetime extensions are considered.

A nuclear power plant can contain up to 2 000 km of cables necessary for signal or electricity transfer, which makes it important but also time and resource consuming to ensure their proper function throughout the lifetime of the plant.

The purpose of this study was to analyse current practices in cable condition management, to identify good practices and possible areas for improvement. The report lists a wide variety of condition monitoring methods and good practices, making it possible for the power plants to benchmark and improve in this important area.

    Silicone rubber in nuclear power plants: prediction of service lifetime in moist conditions

    Components made of silicone rubber are used in Swedish nuclear power plants. Elastic polymer sealants used in pipe transits and joints are examples of applications. It is known that silicone rubber does not resist LOCA. The question is how silicone rubber components behave at normal service conditions.

    Use, limitations and possibilities of Arrhenius based extrapolations for LTO studies of polymeric materials

    Long-term operation of nuclear power plants relies on reliable ageing management of polymeric materials used in safety‑relevant components such as cables, seals and gaskets. Predicting their long‑term performance is essential for safe operation and informed decisions on lifetime extension. This study examines the use of Arrhenius‑based extrapolations in accelerated ageing tests for polymeric materials.
