| Description | The structure of modern nuclear graphites has been characterised using advanced microscopy techniques. Current work is still on-going into the effects of irradiation and temperature on these structures. The work on these Gen IV graphites has also led to new experiments using high resolution X-ray tomography and image correlation techniques to examine graphite properties in small test specimens. |
| Exploitation Route | UK has now rejoined GIF (Generation IV International Forum). The Oxford CI (Marrow) is the UK representative to GIF in the graphite working group on the VHTR system. The UK experience on graphite, including that gained in this project, will be used to contribute to the GIF programme. |
