Nuclear Core Systems Performance Engineer- Submarines

An exciting opportunity has arisen for Nuclear Systems Performance Engineers to join Rolls-Royce Team in Derby. Rolls-Royce Submarines are the UK thought leader for nuclear thermal hydraulics; we employ cutting edge analytical methods today, are championing the development of next generation methods for the future with academia, and have unique experimental testing capabilities. The core thermal hydraulics team works to assess the performance and safety of the reactor core, by ensuring adequate heat transfer throughout its operational life; here analysis is undertaken to develop and optimise core designs, substantiate their thermal performance, and to support manufacturing campaigns.

Our Submarines business is responsible for the design, manufacture, supply and through-life support of nuclear propulsion-related products and systems in support of the Royal Navy's submarine fleet. Join us and we will provide an environment where you can be yourself. An inclusive, digital-first culture that invests in you, gives you a platform for continuous learning, and access to an incredible breadth and depth of opportunities to grow your career.

Teams within plant performance undertake a wide range of thermal hydraulic analyses ranging from detailed predictions of heat transfer in individual components using 3D computational fluid dynamics so that their operational life can be accurately assessed, to 1D systems code models of an entire plant to predict overall performance and ensure its safe operation. This gives rise to a wide range of exciting and interesting workstreams involving fluid dynamics and heat transfer with important real world applications.

We offer excellent development opportunities, a competitive salary, and exceptional benefits. These include bonus, employee support assistance and employee discounts. Your needs are as unique as you are. Hybrid working is a way in which our people can balance their time between the office, home, or another remote location. It is a locally managed and flexed informal discretionary arrangement. As a minimum we are all expected to attend the workplace for collaboration and other specific reasons, on average three days per week.

What you will be doing:

• You will be involved in all aspects of thermal hydraulic analyses of our products, with opportunities to rotate through the wide variety of our different methods and their applications.
• Developing and implementing thermal hydraulic models of various levels of fidelity.
• Undertaking verification and validation activities of thermal hydraulic models, in some cases interacting with the Experimental Engineering Team who undertake testing using onsite rigs.
• Developing production analysis methods, including automation, data assimilation and uncertainty quantification.
• Conducting technical analysis of the core, plant, and specific components in support of safety cases.
• Supporting design and manufacture through bespoke thermal hydraulic assessments of our existing and future products.
• Connecting with other centres of thermal hydraulic knowledge and skills such as our industry partner, civil nuclear and academia.

Who we are looking for:

At Rolls-Royce we embrace agility, are bold, pursue collaboration and seek simplicity in everything we do. These principles form our values and behaviours and are an essential component of our assessment process and are fundamental qualities that we seek for all roles. Thermal hydraulic engineering opportunities are available at all levels from those expecting to graduate in the near-future to experienced senior engineers, with the specifics of each role tailored to the successful candidate. We are looking for candidates with:

• Experience in thermal hydraulics, fluid dynamics and heat transfer.
• A strong academic background with a relevant degree (undergraduate, masters, or PhD) in engineering, physics or a scientific subject.
• An analytical mindset, critical thinking and attention to detail.
• The ability to communicate effectively with any audience, quickly establishing credibility and buy-in.
• A willingness to learn from others and collaborate to achieve wider goals.

We are an equal opportunities employer. We are committed to developing a diverse workforce and an inclusive working environment. We believe that people from different backgrounds and cultures give us different perspectives. And the more perspectives we have, the more successful we will be. By building a culture of respect and appreciation, we give everyone who works here the opportunity to realise their full potential.

To work for the Rolls-Royce Submarines business an individual has to hold a Security Check clearance. Rolls-Royce will support the application for Security Clearance if you do not currently already have this in place. Due to the nature of work the business conducts and the protection of certain assets we can only progress applications from individuals who are a UK national or, in MoD approved cases, a dual national.
