** Role

Title:

** Reactor 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.

We are now recruiting for a Reactor Fault Studies Analyst to join our Performance & Analysis team, the centre of excellence for engineering analysis used to substantiate the performance and safety of the SMR power station.###
** About the Role
** As a performance analyst, you will model fluid and thermal systems that extract power from the nuclear core and ensure safe operation of the reactor. This will involve producing models and analyses that demonstrate reactor operation and working closely with system designers to optimise the design of the plant and its safety systems to maximise safety, performance, and value for money.

Analysis outputs form a key input to the safety case and support the overall substantiation of the power station design. Performance analysts have a key role in supporting the development of and authoring analysis sections of the safety case.

The team uses a wide variety of tools and software to analyse key scenarios for the plant, including:
* Normal operations, when the reactor must produce power and respond to changes in demand from the grid
* Operating transients such as shutting down the reactor and then restarting it for refuelling
* Reactor faults, where passive safety systems are key to protecting the core and ensuring the integrity of the containment.

Due to the safety-critical nature of the modelling we undertake, excellent quality-management processes and code verification, validation and uncertainty quantification are essential. The development of robust and automated analysis routes around the analysis codes, primarily developed using Python on our Linux-based high-performance computing resources, is an important aspect of this.

The performance team collaborates closely with our in-house test capability team, who are building large-scale multi-megawatt test rigs to represent key aspects of the plant to support the validation of the performance analysis tools. There are opportunities within the team to work on benchmarking of our codes against test data and support the development of the test rig designs and associated test campaigns.

As performance analysis supports the development and substantiation of many aspects of the power station design, effective communication and collaboration with teams across a wide range of engineering and non-engineering disciplines is essential.

All performance engineers are responsible for planning their own work to ensure that objectives are met, quality processes are followed, and delivery is on schedule. Depending…
