ALTEN UK is seeking an experienced Fuel Handling Engineer to support the design and development of next-generation fuel handling systems for major nuclear programmes. This is a unique opportunity to contribute to cutting-edge technologies that will shape the future of safe, efficient, and modern reactor operations.

In this role, you will work across the full engineering lifecycle — from early optioneering and requirements capture through to detailed mechanical design, structural assessments, and technical documentation. You will collaborate closely with analysts, design engineers, and project stakeholders to deliver robust, high-integrity fuel handling solutions.

Your work will involve mechanical systems such as Fuel Transfer Channels, Uppenders, Spent Fuel Pools, Dry Cask Storage systems, Fuel Racks, and both in-core and ex-core mechanical components, as well as associated access platforms, cranes, rails, clamps, actuators, and handling mechanisms.

• Lead and support the design of complex fuel handling systems> from concept through to detailed design.
• Define and develop early-stage mechanical concepts, evaluating alternatives through optioneering and trade studies.
• Perform structural calculations, functional assessments, and engineering justification activities.
• Create and review 3D CAD models, assemblies, and technical drawings.
• Develop detailed technical reports, design justifications, and engineering documentation.
• Engage with internal teams and stakeholders to ensure alignment on requirements, interfaces, and design direction.
• Support design activities related to:
• Fuel Transfer Channels
• Uppenders
• Spent Fuel Pools
• Dry Cask Storage systems
• Fuel Racks
• In-core and ex-core components
• Access platforms and lifting/handling mechanisms

• 8+ years in mechanical design, ideally with Nuclear background.
• Strong experience with structural assessments, CAD modelling and concept development.
• Hands‑on involvement with moving mechanical assemblies or fuel handling‑style equipment.
• Familiarity with technical report writing, requirement capture and stakeholder collaboration.

• Experience with nuclear fuel handling or reactor auxiliary systems.
• Background in safety‑critical or highly regulated industries.
• Understanding of optioneering processes, trade studies, or design decision frameworks.
• Exposure to structural qualification, seismic assessments, or heavy lifting systems.

• 8+ years of experience in mechanical design, ideally within the nuclear sector.
• Strong background in mechanical calculations and functional assessment.
• Experience designing or analysing moving mechanical assemblies (e.g., cranes, actuators, clamps, rails, casks).
• Proficient in CAD modelling and creation of engineering drawings.
• Experience with requirements capture, concept development, and technical report writing.
• Familiarity with fuel handling‑related equipment such as Fuel Transfer Channels, Fuel Racks, Uppenders, or spent fuel systems.
• Ability to work collaboratively with analysts, design engineers, and project stakeholders.
