Sellafield Ltd. anticipates the call for competition commencing in April 2026. Design support is a critical enabler to the Sellafield Ltd mission. Delivery of design engineering and safety case support services are essential to the Sellafield decommissioning mission covering new assets, asset care, retrievals, and remediation projects. It will support the intelligent customer function for the other delivery models and provide early-stage client support to conclude the most appropriate point to commence scope transfer (i.e. value transition point).

The scope established to support the Sellafield enterprise aligns to capability provision. At the primary level it aligns to: • Client support – IC design support and independent capabilities, including early front-end design and studies support (pre-value transition point) • Operational support – providing a design and safety case provision to operational nuclear facilities, often needed quickly and with integrated working and on plant access. Value is realised through responsiveness to plant scenarios, minimising equipment downtime and reducing the need for replacement systems with associated Capital Departmental Expenditure Limit(CDEL) expenditure. • Safety case and specialist nuclear capability – supplements existing internal capabilities and focuses on enabling access to specialist skills that otherwise wouldn’t be sustainable as part of full lifecycle delivery models.

Contract 1 – Design support to Plant-Facing Design Office (PFDO) civil, structural and architectural 2.
