About this position

This PhD project at the University of Bristol focuses on understanding the effects of water chemistry on the operation and maintenance of new small modular reactor (SMR) coolant circuits. SMRs are an emerging class of pressurised water nuclear reactors designed for improved construction efficiency and cost-effectiveness. As these reactors are developed, it is crucial to understand how their materials respond to operational conditions, particularly regarding corrosion processes in the high-pressure, high-temperature water coolant loops.

The project will investigate how anticipated SMR water chemistry regimes affect reactor components, such as steam generators, and how subtle changes in water chemistry can significantly impact metal surfaces. Experimental work will use the University of Bristol's autoclave facilities to expose reactor materials to SMR-specific water conditions, followed by advanced microscopy analysis at the Interface Analysis Centre (IAC). The research will combine experimental and modelling approaches to elucidate how water chemistry influences reactor components, the movement of corrosion products, and strategies to optimise coolant circuit performance.

The student will be based in the IAC within the School of Physics, benefiting from access to state-of-the-art testing and characterisation facilities, and will be supported by Dr Tomas Martin, Dr Mariia Zimina, and the broader IAC team. The project is embedded in a vibrant research community with strong links to the nuclear industry through the South West Nuclear Hub. Funding is available for home students, covering living expenses at the UKRI rate, tuition fees, and training costs. A limited number of fully-funded places are available for outstanding international candidates, while others may need to secure additional funding.

Applicants should have a first degree in physics or a related subject (minimum UK upper second-class honours or equivalent), and meet English language requirements (Profile F). The application process requires a CV, personal statement, and transcripts, with applications submitted via the University of Bristol's online system. The deadline for applications is 19 January 2026. The School of Physics is committed to diversity and equality, encouraging applications from under-represented groups.
