About
Dr. Gareth Frank Stephens is a Postdoctoral Research Associate at Bangor University's School of Computer Science and Engineering, affiliated with the Nuclear Futures Institute. His research focuses on nuclear materials science, particularly the corrosion mechanisms of zirconium alloys in nuclear reactors, with an emphasis on lithium's role in material stability. He holds a PhD in Materials Physics from Aberystwyth University (2019) and completed his doctoral research at Bangor University, funded by Jacobs (now Amentum) and the Nuclear Energy Futures Centre for Doctoral Training (EPSRC).
Education:
- MPhys Masters in Materials Physics, Aberystwyth University (2014–2019)
- PhD in Nuclear Materials Science, Bangor University (2024)
Dr. Stephens investigates cladding materials for nuclear reactors, focusing on lithium accommodation in zirconium-based alloys and its impact on corrosion. His work combines experimental validation and computational modeling to understand defect chemistry and material behavior under extreme conditions. Key areas include nuclear fuel performance, high-temperature reactors, and space systems.
Publications: His recent work includes studies on lithium stabilization in ZrO₂, kernel fuels for high-temperature reactors, and corrosion mechanisms in nuclear materials.
Engagement & Projects: He actively participates in initiatives like the MUZIC-3 international collaboration on zirconium corrosion and the Nuclear Energy Futures CDT. He contributes to public outreach, such as the 'Girls In STEM Day' to inspire school students in science and engineering.
Labs/Teams: Part of the Nuclear Futures Institute at Bangor University, collaborating with industry partners like Amentum and academic institutions globally.
