Clive Young Award for Distinguished Oral Presentations

Technetics recently delivered a technical presentation in Kobe, Japan as part of the PATRAM show. Florent Ledrappier of the maestral R&D lab represented Technetics during the “Numerical Simulation of HELICOFLEX® Metallic Gasket Aging Mechanism for Spent” presentation and was honored with the Clive Young Award for Distinguished Oral Presentations.

The PATRAM show is the International Symposium on the Packaging and Transportation of Radioactive Materials. This event, which brings together over 600 worldwide experts from government, industry, and research, consists of roughly 250 presentations centered on the design, manufacture and qualification of nuclear containers.

During the presentation, Ledrappier discussed the results of research focusing on the aging of HELICOFLEX® seals, work carried out in collaboration with CEA (French Alternative Energies and Atomic Energy Commission), GNS (German cask container manufacturer), CRIEPI (Central Research Institute of Electric Power Industry), and the Japanese Institute for Research on Energy and Environment. The study included a statistical analysis of nearly 450 measurements made on nearly 100 seals, some of which had spent more than 12 years in an oven at 200°C (392°F). This analysis made it possible to estimate the properties of the seals after more than 60 years of storage. The experimental results were then compared with numerical simulations carried out with techniques specifically developed for nuclear containers. In the end, the results highlighted the excellent performance of HELICOFLEX® seals for this application—and illustrated Technetics’ ability to use numerical simulation to help in the qualification of seals for containers.

The Clive Young Awards were established by the event’s organizing committee in the memory of Mr. Clive Young, a pioneer in radioactive material packaging and transport safety who also had a keen interest in ensuring younger professionals become enthusiastically involved in this vital field.
