Cable condition monitoring methods for nuclear power plants
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.

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.
