Abstract Scope |
The fundamental research directed at the interaction of radiation, the environment (liquid or gaseous) and material at relevant temperatures to study the response of structural alloys for future fission and fusion reactors is ambitious and very challenging. Analytical electron microscopy (AEM) characterisation of non-irradiated and irradiated structural nuclear alloys in relevant environments can provide unique opportunities to assess the nanoscale defects, radiation-induced segregation via high spatial resolution STEM-EDX analyses, and environmental interactions using in situ stages, including studies of post-irradiation annealing/recovery of irradiation damage. A combined AEM-in situ platform provides opportunities to explore nanoscale reactions at temperatures up to 1000°C in gaseous environments. The new RadIAEM facility, which is part of the UK National Nuclear User Facilities and based in the Materials Research Facility at Culham, will provide the ability for both fission and fusion researchers to conduct in situ gas-metal reaction studies focused on existing and new materials. |
