Senior Thermal Containment Fault Analyst

Advanced Nuclear / SMR Programme
\n Location: Derby / Manchester / Warrington | Hybrid Working Available
\n Salary: £50,000 - £66,500 + Bonus & Excellent Benefits

Morson are supporting a pioneering advanced engineering organisation as they continue to expand their specialist Performance & Analysis capability, contributing to one of the UK's most exciting low-carbon energy programmes.

This is a rare opportunity to play a key role in containment analysis and fault studies, working at the forefront of reactor safety, modelling, and performance within a highly regulated and safety-critical environment.

Working within the specialist Performance & Analysis function, you will take a senior role in the development and application of thermal-hydraulic models used to assess containment behaviour and safety system performance under fault conditions.

You will technically lead small teams, delivering complex analysis that supports plant design optimisation, safety case development, and regulatory substantiation. This role involves close collaboration with multidisciplinary teams across design, safety, and testing to ensure robust, validated, and high-quality analytical outputs.
