Megan Jones

• PhD Student - University of Oxford

• Project Title: Enabling 3D atomic-scale imaging of hydrogen in zirconium alloy fuel claddings

Megan Jones completed a MEng in Materials Science at the University of Oxford. In 2018, she started her PhD at the Department of Materials, University of Oxford under the supervision of Dr Daniel Haley and Prof. Michael Moody.

Megan’s PhD project aims to use Atom Probe Tomography (APT) to analyse hydrogen distributions in Zircaloy-4. With deuterium tracing, APT can be used to image deuterium, providing direct experimental evidence on hydrogen phenomena such as hydrogen trapping at precipitates. This project focuses on improving current deuterium charging protocols and data analysis techniques to investigate the effect of damage levels on hydrogen pick up in Zircaloy-4, using cold worked samples.

Next Steps: Following completion of her PhD, Megan has taken a role at the National Nuclear Laboratory. Her new role will build on the nuclear materials expertise developed during her PhD studies, and she remains engaged with the MIDAS community.
