Qualification of polymer materials for nuclear power applications

| 2024:1050 | Anna Bondeson
This study aimed to investigate how the Nordic power plants work with qualification of polymeric materials. The results can be used as a benchmark and base for improvements.

\u003Cp\u003EPolymer materials and products such as sealings, pipes, insulation, and cables are everywhere in a nuclear power plant. But, information on important technical specifications, such as exact material composition, is still hard to obtain. This study aimed to investigate how the Nordic power plants work with the issue of qualification of polymeric materials. The survey shows that there is no common qualification process, but that the processes most often follow the processes of the technical area (electrical, mechanical or construction) that the polymeric components are considered to belong to.\u003C/p\u003E

    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.
