UK1 - Pipeline Notice
Summary of the contracting process

Sellafield Limited intends to procure specialist safety case and assessment support for nuclear operations, programme delivery and safety case improvement initiatives. The service may cover safety case development and review, radiological safety, criticality assessment, human factors, human performance, dose and shielding assessment, and fire safety across nuclear and conventional environments. This is a professional services requirement, with the related classification describing design support services. The work is intended to support Sellafield’s operational and programme teams rather than the supply of physical goods or construction works. It is structured as a single planned requirement, with delivery associated with Sellafield’s nuclear operations and improvement programmes.

This procurement is at the planning stage: Sellafield Limited has announced an intention to buy, but has not issued an invitation to tender. The expected route is a call-off through the Crown Commercial Service RM6356 framework, with a framework agreement involved. The planned contract period is 1 October 2026 to 30 September 2030. Its estimated value is £33,000,000 excluding VAT, or £39,600,000 including VAT. The requirement is above the applicable threshold and is planned as one lot. The buyer has revised its wider Design Support Procurement strategy from ten individual mini-competitions to three tranche competitions with sub-lots; Safety Case is listed within Tranche Three. Future competition material and timelines are expected through Atamis.

When this requirement reaches the market, it is likely to suit specialist consultancies, engineering organisations and experienced nuclear-sector teams able to provide safety case and technical assessment capability across several disciplines. Relevant preparation should include demonstrable competence in nuclear safety case work, radiological protection, criticality, human factors and performance, dose and shielding, and fire safety covering both nuclear and conventional settings. Suppliers with the breadth to support nuclear operations, programmes and safety case improvement initiatives may be well placed, including businesses able to assemble multi-disciplinary teams or work through the framework route. The lot is identified as suitable for small and medium-sized enterprises, so capable SMEs may be able to participate directly or contribute specialist services within the planned competition structure.
