Resistance to amorphisation in Ca1-xLa2x/3TiO3 perovskites - a bulk ion-irradiation study

| Description | Huddersfield's role in this multi-institution, collaborative project was to carry out in-situ ion irradiation in a transmission electron microscope of specimens synthesised by other partners. The purpose of this was to simulate the effects of neutron irradiation in nuclear reactors. Of particular interest were changes, in the different perovskites, in the atomic structure - in particular, we successfully determined the the doses and temperatures at which amorphisation (the complete loss of crystalline structure) occurred. However, due to challenges in the synthesis of the intended variety of single-phase perovskites, we were not able to acquire as large a data-set as originally intended. |

| Description | 5th International 5th Workshop On TEM With In Situ Irradiation |
| Form Of Engagement Activity | Participation in an activity, workshop or similar |
| Part Of Official Scheme? | No |
| Geographic Reach | International |
| Primary Audience | Professional Practitioners |
| Results and Impact | The event was the three-day 5th Workshop On TEM With In Situ Irradiation, known as WOTWISI-5. It was attended by scientists from nine countries, including the USA, Japan, China, Australia and Finland. They are specialists in a technique that allows the minute observation of radiation damage in a wide range of materials whilst the irradiation is being induced with ion and/or electron beams. The nuclear industry is a key sector for this research. Previous gatherings have taken place in Japan, France and the USA and the inaugural WOTWISI was in 2010, in Salford, where it was launched by Professor Stephen Donnelly and Dr Jonathan Hinks as part of the EPSRC-funded project "Worldwide network of in-situ TEM/ion accelerator facilities ( EP/F012853/1). |

| Results and Impact | Joint ICTP-IAEA Workshop on Radiation Effects in Nuclear Waste Forms and their Consequences for Storage and Disposal (12 - 16 September 2016) PURPOSE The Workshop aims to gain awareness on the most recent findings of research into radiation effects in nuclear waste forms and their role for waste storage and disposal. It aims to contribute to the transfer of specific knowledge to Member States towards their capacity building efforts and competence in nuclear waste immobilisation and disposal. FOCUS The workshop will focus mainly on experts on radiation effects in materials to explore the potential of both experimental and theoretical/computational approaches aiming to understand the consequences of irradiation of materials under extreme conditions, particularly focusing on long-term irradiation conditions envisaged for nuclear waste forms containing long lived fission products and actinides. |
