Summary of the contracting process

The procurement process for the project titled "C24612 - Early Legacy Boxes - Liner and AFP" was overseen by Sellafield Limited, a nuclear organisation based in Warrington, United Kingdom. The process involved the award of a contract to manufacture specific components designed for the storage and disposal of Intermediate Level Waste (ILW) at Sellafield's Box Encapsulation Plant (BEP) in Cumbria. This procurement, now at the Award stage, concluded with Bendalls Engineering Ltd as the supplier on 19th September 2025. The procurement was executed under a restricted procedure focusing on the "goods" category, specifically within the manufacturing solutions sector. The tender required a pre-defined quality to price ratio, with emphasis on mature manufacturing methods, and achieved the award criteria of 80% for quality and 20% for price.

This tender represents significant opportunities for businesses specialising in the manufacture of nuclear waste containment systems and related fabricated products. The requirement for delivering up to 60 liner and AFP assemblies in the coming years indicates a longer-term engagement, providing stability and potential growth for manufacturers. Companies that can demonstrate expertise in mature manufacturing methods and maintain high standards of quality while meeting cost benchmarks are well-positioned to benefit. The contractual terms allow for subcontracting, thus broadening the scope for collaborative growth between SMEs and larger manufacturing entities.
