Working at the forefront of advanced nuclear technology, you''ll play a key role in developing confidence in the analytical tools and methodologies that underpin reactor safety and performance.

The Role

As a Senior Analysis Code Validation Engineer, you''ll work within a specialist VVUQ team supporting the validation, verification and continuous improvement of thermal hydraulic analysis methods, models and software.

You''ll collaborate closely with reactor performance, methods development, testing and safety teams, ensuring analysis tools are robust, validated and fit for application within a safety-critical environment.

The role offers exposure across reactor systems analysis, core thermal hydraulics, containment analysis and advanced modelling techniques used throughout the design and licensing lifecycle.

Key Responsibilities

• Verification, Validation & Uncertainty Quantification (VVUQ) of thermal hydraulic analysis codes
• Development and validation of analysis models against experimental test data
• Benchmarking analytical predictions against large-scale thermal hydraulic test programmes
• Supporting the development of analysis methodologies and modelling approaches
• Quantification of modelling uncertainties using statistical and engineering judgement-based methods
• Sensitivity studies and assessment of model assumptions
• Development of Python-based analysis tools and automation
• Working within Linux and High-Performance Computing (HPC) environments
• Supporting reactor safety case substantiation and design validation activities
• Technical leadership of analysis and validation activities across multidisciplinary teams
