Gareth Stephens

Dr. Gareth Stephens is a Postdoctoral Research Associate at Bangor University's Nuclear Futures Institute, supported by Amentum. He earned a Master's in Materials Physics from Aberystwyth University (2019) and completed his PhD (2024) through the Nuclear Energy Futures Centre for Doctoral Training (EPSRC-funded), with industry collaboration from Jacobs/Amentum.

His research focuses on zirconium alloy cladding corrosion in nuclear reactor environments, particularly under lithiated water conditions, investigating oxidation mechanics and material degradation to improve reactor fuel performance and safety. This work combines computational simulations with experimental validation.

Gareth is affiliated with the

• Nuclear Futures Institute at Bangor University
• Nuclear Energy Futures Centre for Doctoral Training

and was supervised by Prof. Simon Middleburgh during his PhD.
