Lifetime prediction of polymers in nuclear power plants 2022
| 2023:960 | Anna Bondeson, Henrik Toss, Mohit Pushp And David Kiefer
This report summarizes the results from the SAMPO project, which has been ongoing for four years. The purpose of the project was to establish relevant acceptance criteria for the components' lifespan and to improve material handling through methods such as online monitoring of materials.

\u003Cp\u003EWithin SAMPO safety criteria and improved aging management research for polymer components exposed to thermal radiation environments was the focus. SAMPO was a collaborative project in cooperation with VTT in Finland and RISE, conducted in close collaboration with the nuclear power industry. Polymer researchers worked together with experts in sensor technology and sensitive analytical techniques to enhance the understanding of how plastic and rubber materials degrade during long-term use in nuclear power plants.\u003C/p\u003E

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.
