Lead containment and emergency cooling system modelling activities, producing high‑fidelity thermal‑hydraulic analyses
Demonstrate the effectiveness of containment and safety systems under fault conditions and normal operation
Work closely with system designers to influence design, control strategies and system performance
Contribute analysis outputs that form key inputs to the safety case and support safety case authorship
Model key plant scenarios including: Normal operation and grid‑response
Operational transients such as shutdown and restart
Faulted conditions where passive safety systems are essential to protect the core
Apply rigorous quality‑management processes, including verification, validation and uncertainty quantification
Develop automated analysis workflows, including Python‑based routes on high‑performance Linux computing platforms
Support code benchmarking against experimental data and collaborate with in‑house test teams developing multi‑megawatt test rigs
Work flexibly across multidisciplinary teams, shaping analysis requirements and communicating results clearly
Provide technical leadership to small teams and support capability development within the function

Strong experience in fluids and thermal analysis, applying structured and methodological approaches
Good understanding of fluid dynamics, thermal processes and system behaviour
Experience producing analysis reports and contributing to analysis sections of safety cases
Familiarity with industry‑standard thermal‑hydraulic tools (e.g. RELAP, Flomaster, GOTHIC, VIPRE, CTF)
Experience developing analysis methods, models and tools, ideally with Python
Understanding of software development processes and analysis QA requirements
Experience with verification, validation, benchmarking and uncertainty quantification
Familiarity with thermal‑hydraulic test rig design and supporting experimental campaigns
Knowledge of fluids/process/power‑generation plant in safety‑critical sectors (nuclear/defence/oil & gas/aerospace)
Understanding of PWR behaviour, fault scenarios, reactor design substantiation and safety case principles (training can be provided)
Knowledge of E3S regulations and principles including ALARP and BAT
Proven ability to deliver analysis tasks to time, cost and quality
Strong communication skills, able to clearly articulate complex analysis
Experience technically leading teams and collaborating effectively across organisational boundaries
Degree in Engineering, Physics, Mathematics, Computer Science or related discipline; Chartered status (or equivalent) is preferred
