This active procurement process falls under the services category, specifically focusing on decommissioning services related to the design, construction, and operation of waste treatment facilities for the Shaft and Wet Silo. The open tender method is being utilised, with a submission deadline set for 5 November 2021. This project has a total value of £15 million and the contract duration is approximately 1230 days. This tender presents a significant opportunity for businesses specialising in waste management, environmental services, and construction within the nuclear decommissioning sector. Companies equipped to design and build complex waste processing facilities, as well as those with experience in handling hazardous materials, will be particularly well-suited to compete. Engaging in this contract could facilitate growth and broaden the project portfolio for potential bidders in the growing field of nuclear decommissioning services. ## Notice The scope of the Shaft and Silo Decommissioning Project is to design, build and carry out the operation of the facilities for retrieval, treatment and packaging of the Shaft and Wet Silo waste contents. The finalised scheme design of the Process Cell includes a series of independent Plant items that provide the means to sort, segregate and size reduce the Wet Silo and Shaft solid waste and batch that waste into 200L drums ready for downstream assay and packaging for long-term safe storage. The Process Cell Plant also separates and collects the corresponding Liquid and Sludge Waste, and conditions it to produce a concentrated sludge waste stream that is metered into modified 200L drums pre-filled with cement powders. The Liquid Waste is further filtered, and the subsequent grey water is re-used within the Process Cell before being ultimately discharged to the downstream Effluent Treatment Plant. ### Lot Information Lot 1 The scope of the Shaft and Silo Decommissioning Project is to design, build and carry out the operation of the facilities for retrieval, treatment and packaging of the Shaft and Wet Silo waste contents.
