Polymers in nuclear applications 2021

Most welcome to submit a presentation for the conference. All topics relating to polymers in nuclear applications are included. Results from ongoing R&D projects will be presented, and we would also like to invite nuclear power plants, suppliers, consultants and researchers to contribute with presentations.

Polymeric materials are used for many applications in nuclear power plants. They are quite complex, since their properties and aging mechanisms are highly dependent on their composition. The research in the SAMPO project is focused on safe long-term use of polymer components and improving their ageing management. This is done by studying ageing mechanisms of polymers, determining how to set acceptance criterion properly and providing robust tools for condition monitoring.

These topics become more relevant as the original planned lifetime of the plants is approaching and extension is considered. Safety criteria assessment and ageing management needs to be at sufficient level in order to prevent premature component breakdown and avoiding endangering the overall safety. The SAMPO project is financed by the Finnish Nuclear Waste Management Fund, the Swedish Radiation Safety Authority, VTT Technical Research Centre of Finland Ltd and the owners of the Swedish and Finnish nuclear power plants.

Submit a presentation by sending an e-mail to Monika Adsten at the latest by August 18. Describe your presentation and your affiliation shortly.

Price and registration

Registration will open in September. We are hoping for a hybrid event with an opportunity to meet face-to-face at Ringhals NPP in Sweden, but it will also be possible to participate virtually.
