Role Title: Senior Engineer - Containment Analysis
We are Rolls‑Royce SMR, working on an unprecedented opportunity to revolutionise the nuclear industry. The Performance & Analysis team is the centre of excellence for engineering analysis that substantiates performance and safety of SMR power stations. Containment analysis plays a critical role in understanding system behaviour during transients, operational scenarios and faulted conditions, supporting the safety case and informing key design decisions.
About the Role
As a Senior Containment Fault Studies Analyst you will lead thermal‑hydraulic modelling of the containment and emergency cooling systems, producing analyses that demonstrate system performance across a wide range of operating and fault scenarios. Your work will be central to demonstrating the effectiveness of safety systems, optimising plant design and substantiating key elements of the safety case.
Key Responsibilities
* 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, and 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
Key Skills Required
* 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 (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
Qualifications
* Degree in Engineering, Physics, Mathematics, Computer Science or related discipline
* Chartered status (or equivalent) is preferred
