We are Rolls‑Royce SMR and we’re doing something that’s never been done before. We’re revolutionising an industry. That’s a once‑in‑a‑career opportunity for those excited by such a challenge. This is more than just a job; this is a legacy.
The Performance & Analysis team is the centre of excellence within Rolls‑Royce SMR for the engineering analysis used to substantiate the performance and safety of the power station.
Multiple opportunities are available across thermal hydraulic plant performance and safety analysis, including reactor plant transient and fault analysis, core sub-channel analysis and containment analysis. The team provides the technical evidence needed to support design decisions, safety case development and regulatory compliance across the SMR programme.
As a Containment Fault Studies Analyst, you will model the thermal-hydraulic behaviour of containment systems and their associated emergency cooling systems.
You will develop engineering models and analyses that demonstrate the effectiveness of containment and safety systems during faulted conditions, using the results to support design optimisation and the substantiation of nuclear safety claims. Analysis outputs form a key part of the safety case and contribute directly to the verification and validation of the SMR design.
You will work closely with design engineers, safety specialists, performance analysts and test teams, helping to define analysis requirements and communicate results across a wide range of technical disciplines.
