Radiation induced hardening by neutrons in nuclear structural materials has ramifications for safety, structural integrity and reliability. Handling neutron irradiated specimens requires specialist facilities and lengthy lead times (years). In developing the next generation of damage resistant/tolerant structures we are aiming to use ion irradiation in lieu of neutrons to speed up the analysis process and allow for easier handling, with no radioactivity. Small scale nano-indentation experiments are combined with multi-scale numerical and analytical modelling to establish frameworks for assessment, since ion irradiation affects an extremely shallow surface region. Our aim is to provide new insights into the derived results and to further the state of the art in this safety critical field.
