Cable condition monitoring methods for nuclear power plants

| 2024:1016 | Konsta Sipilä
To monitor cable ageing accordingly, suitable condition monitoring methods are required. This report lists potential condition monitoring methods to be applied to NPP cables and assesses their strengths and weaknesses. The results can be used when suitable condition monitoring methods are chosen for NPP trials.

Low- and medium voltage cables are used in nuclear power plants (NPPs) as part of instrumentation and electrical equipment to supply electricity or signal transfer. Typical estimates are that a single NPP contains such cables at approximately 1000-2000 km. Cables are subjected to ageing due to different environmental stressors like temperature, radiation and moisture.

    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.

    Cable Condition Monitoring Experiences at Nuclear Power Plants

    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.
