    Brief

    Sellafield Ltd is conducting a second phase of preliminary market engagement to gather supplier feedback on the manufacture and assembly of Miscellaneous Beta Gamma Waste (MBGW) Boxes. This follows an initial market engagement in January 2026 that confirmed strong market interest and identified capable suppliers. The company is seeking input on supplier capacity, mobilisation timelines, and commercial terms to finalise its procurement strategy. The preferred approach is for a single supplier to handle full assembly of the boxes to Sellafield's specifications. The requirement includes manufacturing, assembling, testing, and delivering MBGW Boxes, with anticipated demand of 11 to 33 units per year. This is a market engagement exercise only and not a formal call for competition.
