Examination of two In-Service-Aged PVC Cables from a Nuclear Power Plant
A thorough examination of the cable materials and an accelerated ageing study showed that the cables differed in their composition, but that both had the potential to perform satisfactorily for another 20 years in service. The main ageing mechanism leading slowly to a stiffer material is loss of the DEPH plasticiser.

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.

Thresholds for radiation sensitivity of polymers in combined radiation-thermal environments
Available data for polymer degradation in combined radiation-thermal environments can be used to justify radiation threshold values below which radiation effects are of little consequence to useful material properties.
