| Abstract Scope |
Commercial fusion reactors will be one of the most extreme environments for materials, operating at high temperatures under stress while simultaneously exposed to 14 MeV neutrons, corrosive chemicals, and gaseous species. Ceramics will play an essential role in these systems, either as superconducting magnets driving the plasma, neutron shielding protecting the magnets, permeation barriers inhibiting the release of tritium, or structural materials supporting the breeder/coolants in the blanket. During service, these ceramics will undergo transmutations that may affect their structural and functional properties.
This presentation will cover R&D activities at UKAEA on advanced ceramics intended for fusion applications. Predictions of the transmutation elements and their quantities in these ceramics will be provided. In addition, details will be given on the various methods being employed to simulate transmutation effects in these advanced materials as well as the test techniques being developed to enable us to compare changes in their performance. |
