Senior Containment Fault Studies Analyst
About the Role
As a Senior Containment Fault Studies Analyst, you will lead thermal-hydraulic modelling of reactor containment and associated emergency cooling systems. You will deliver high-fidelity analyses that demonstrate system performance across a wide range of operating and fault conditions, supporting the effectiveness of safety systems, optimising plant design, and contributing to key elements of the nuclear safety case.
You will work closely with system designers, safety case engineers, and experimental teams to ensure models are robust, validated, and aligned with safety and performance requirements. The role also involves contributing to the development of analysis methods, verification and validation processes, and continuous improvement of modelling tools and approaches.
Senior analysts are responsible for planning and delivering technical work, leading small teams, and supporting capability development across the wider engineering function.
Key Responsibilities
- Lead containment and emergency cooling system modelling activities
- Deliver high-quality thermal-hydraulic analyses to demonstrate system performance
- Analyse plant scenarios including:
- Normal operation and grid response
- Operational transients (e.g. shutdown and restart)
- Fault conditions involving passive safety systems
- Support and contribute to nuclear safety case development and authorship
- Work with system designers to influence plant design, control strategies, and system performance
- Apply rigorous verification, validation, and uncertainty quantification (VVUQ) processes
- Develop and maintain automated analysis workflows using Python on Linux-based HPC systems
- Support benchmarking of analysis tools against experimental data
- Collaborate with test teams supporting large-scale experimental programmes
- Communicate analysis results clearly across multidisciplinary teams
- Provide technical leadership and mentor engineers within the team
Key Skills & Experience
- Strong background in fluid dynamics and thermal analysis
- Experience applying structured and methodical engineering analysis approaches
- Familiarity with thermal-hydraulic tools such as RELAP, FLOMASTER, GOTHIC, VIPRE, or CTF
- Experience developing models, methods, and analysis tools (Python desirable)
- Experience in verification, validation, benchmarking, and uncertainty quantification
- Ability to produce clear technical reports and contribute to safety case documentation
- Understanding of safety-critical systems within sectors such as nuclear, defence, oil & gas, or aerospace
- Knowledge of reactor behaviour, fault scenarios, and safety case principles (training can be provided)
- Awareness of regulatory principles such as ALARP and BAT
- Proven ability to deliver technical work to time, cost, and quality
- Strong communication and collaboration skills
- Experience leading or mentoring engineers
Qualifications
- Degree in Engineering, Physics, Mathematics, Computer Science, or a related discipline
- Chartered Engineer status (or working towards) is desirable
Location & Working Pattern
- Hybrid working
- Primary locations include Derby, Manchester, or Warrington
Benefits
- Performance-related bonus
- Flexible benefits allowance
- Pension scheme
- Annual leave plus public holidays (with option to buy/sell)
- Private medical insurance
- Life assurance
- Home office support
