Job Description

Applications are invited for a fixed term, full time Research Officer working in the Nuclear Futures Institute within the School of Computer Science and Engineering at Bangor University.
The Research Officer will carry out research relating to neutronics and core design for molten salt reactors. Duties will include safety analysis of the graphite-free fluoride-salt high temperature reactor (FHR) system (WP3) being investigated in this project. This includes salt-freezing prevention, decay heat removal analysis and assessment of online refuelling strategy. And experimental design for refuelling-related safety including heat transfer modelling, flow analysis, and stringer drop simulation.
Candidates should be educated to PhD in reactor physics, (or be close to the completion) or possess equivalent experience relevant to the role, and have previous experience simulating nuclear systems with multi-physics modelling methods.
The successful candidate will be expected to commence as soon as possible and the role is available until 31st May 2028.
This role will be located on campus at Bangor. Through our Dynamic Working framework, there will also be the option to spend some time working remotely (although remaining in the UK) to support work life balance, which will be discussed further with candidates at interview.
Applications will also be considered to carry out this role on a part-time or job share basis.
Applications will only be accepted via our on-line recruitment website, jobs.bangor.ac.uk. However, in cases of access issues due to disability, paper application forms are available by telephoning 01248 383865.
Closing date for applications: 22 October 2025
Informal enquiries can be made by contacting: Prof Simon Middleburgh Co-Director of the Nuclear Futures Institute - s.middleburgh@bangor.ac.uk
Committed To Equal Opportunities
Overview
Bangor University, located in Bangor, North Wales, is a respected public university known for its strong academic reputation, stunning natural surroundings, and supportive student environment. Established in 1884, the university offers a wide range of undergraduate and postgraduate programs across disciplines such as science, arts, business, education, health, and environmental studies.
Work will primarily be undertaken in the Nuclear Futures Institute which is located in the School of Computer Science and Engineering in Bangor University's Dean Street building. Additionally, the role will involve a significant collaboration with Bangor's School of Ocean Sciences and members of the Centre for Environmental Biotechnology.
The Nuclear Futures Institute was established over five years ago to develop a capability in nuclear science, engineering and related skills at the university. Now the institute has around 40 researchers conducting work that touches almost all parts of the fuel cycle for nuclear fission and fusion energy.
The Project
Bangor University will lead the safety and experimental validation aspects of the graphite-free Fluoride-salt-cooled High-temperature Reactor (FHR) concept. The research will focus on evaluating key safety challenges, including primary salt freezing, decay heat removal, and online refuelling integrity. Using a combination of 1D system modelling, CFD simulations, and structural analysis, the team will assess the system's behaviour under accidental and transient conditions, such as loss of flow or fuel assembly drop events.
In parallel, the team will develop scaled experimental concepts to investigate thermal-hydraulic phenomena unique to this reactor design, including standpipe heat transfer and flow redistribution during refuelling. These experimental setups will be designed using dimensionless analysis to ensure representative behaviour at reduced scale and cost. The work will provide essential validation for computational models and support the development of a robust safety case for future deployment of AGR-like FHR systems.
Purpose of the Job
This post-doctoral Research Officer position associated with the Enabling Pin-type Graphite-Free Salt-Cooled Reactor Designs project is part of an established team (including Prof Shwageraus at the University of Cambridge) working in the area of nuclear engineering.
