Here's how I turned two summer placements into a full‑time career in mechanical engineering in nuclear.
Hi, I'm Ryley, a Mechanical Engineer at AtkinsRéalis. I've worked in the nuclear industry, focusing on decommissioning, for three and a half years after completing an MEng in Mechanical Engineering at the University of Leeds. Before joining permanently, I completed two eight-week summer placements with AtkinsRéalis, where I became fascinated by the challenges of decommissioning and driven to engineer a better future.
Starting my career in nuclear engineering
Starting as a graduate mechanical engineer was exciting but daunting. From day one, I was surrounded by experienced people who were generous with their time and knowledge. I was trusted with real project work early on – from design reviews and calculations to technical documentation – which helped me build confidence quickly.
Regular feedback, structured training, and support for chartership have guided my growth. At the same time, the organization's focus on wellbeing and flexibility keeps me motivated to do my best work. I've always felt part of a culture that values curiosity, collaboration, and innovation – where asking questions is encouraged, and every voice is heard.
Graduate projects that make an impact in the UK nuclear industry
I'm currently helping design a uranium ore processing plant that converts natural uranium ore into uranium hexafluoride for making nuclear fuel rods. My focus is on mechanical handling – designing systems that move and store materials safely and efficiently throughout the facility's life. It's a complex challenge that demands precision engineering, strict safety standards, and close collaboration across disciplines.
What excites me most is knowing the work contributes directly to clean energy and a more sustainable future. Nuclear energy often gets misunderstood, but it's a critical part of achieving net zero, and being part of that journey feels meaningful.
Mechanical engineering in nuclear – what I've learnt
My work spans the full project lifecycle – from concept design through to commissioning – developing high-integrity systems for handling, transport, and processing materials. Each design must meet demanding safety and regulatory standards, whether for new nuclear facilities or decommissioning legacy ones.
The variety surprised me most. Nuclear engineering isn't narrow or repetitive; it's diverse, fast-moving, and deeply collaborative. One day I might be designing remote-handling equipment, the next developing decontamination or waste-packaging strategies. Each project offers new challenges and the chance to work with experts from across mechanical, civil, and electrical disciplines.
That exposure has given me a broad understanding of how everything fits together, and the satisfaction of seeing how mechanical design underpins the safe, efficient operation of an entire facility.
Why I'm excited about the future of nuclear engineering
I'm driven by solving complex problems and seeing designs come to life. AtkinsRéalis has helped me develop that passion – giving me early responsibility, technical depth, and mentorship that's building my path toward leadership.
The combination of purpose and opportunity is what keeps me motivated. Every day, I know my work contributes to something bigger: managing nuclear legacies safely and shaping the next generation of clean-energy solutions.
Working here has shown me that engineering isn't just about technical skill – it's about teamwork, trust, and having the confidence to make a difference.
Advice for graduates considering a career in nuclear engineering
If you're thinking about starting your career in nuclear, say yes to every learning opportunity. The industry needs curious, adaptable engineers ready to shape the future of clean energy – whether through decommissioning, design, or even nuclear fusion.
