Technical Excellence in Nuclear Process Engineering

Process Solutions (Nuclear) Ltd provides specialist process engineering consultancy to the UK nuclear industry, with particular expertise in decommissioning and radioactive waste management.

With over 25 years of direct experience in nuclear process engineering, we deliver effective, technically robust solutions across some of the UK's most challenging decommissioning programmes. Our approach combines deep technical knowledge with practical delivery experience, ensuring solutions that meet both regulatory requirements and operational realities.

We have successfully delivered design solutions across the full lifecycle, from feasibility and concept design through to detail design, installation, and commissioning. Our expertise spans both client-side technical leadership roles and direct design management positions, providing us with comprehensive insight into successful project delivery.

Working collaboratively with site operators, regulators, and the supply chain, we develop solutions that are endorsed by regulatory bodies and proven through rigorous testing and validation programmes.
