Thermofluids Engineer / Containment Fault Studies Analyst

Rolls-Royce SMR · Manchester, England, United Kingdom

FULL TIME

Job Description

Role Title:

Containment Fault Studies Analyst

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.

About the Team:

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.

About the Role:

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.

We’ll Need You To:

Develop and execute thermal-hydraulic containment analyses

Model containment performance and emergency cooling system behaviour

Assess plant operation during: Normal operating conditions Operational transients Reactor fault scenarios

Support the substantiation of containment and safety system performance

Produce technical reports and safety case contributions

Develop and maintain analysis methods, models and tools

Support code verification, validation and uncertainty quantification activities

Develop robust and automated analysis workflows using Python and associated tools

Support benchmarking of analytical methods against experimental data

Collaborate with multidisciplinary teams to define analysis requirements and communicate findings

Plan and deliver engineering work to agreed quality, schedule and governance requirements
