DNWP0016 - WAGR Enabling Works and Strip-out - Sellafield - A2R JV
The contract covers enabling works, internal and external strip-out, waste management and decommissioning support at the Windscale Advanced Gas-cooled Reactor (WAGR) facility at Sellafield. The buyer is Altrad AtkinsRéalis Joint Venture (A2R JV), which supports high-hazard nuclear remediation and decommissioning programmes. The supplier will be expected to remove fixtures, equipment and non-structural elements; manage Low-Level Waste and Intermediate-Level Waste; undertake radiological, hazardous and operational surveys; plan asbestos work; provide decontamination, temporary works and scaffolding; procure equipment; support asset reinstatement and plant modifications; and respond rapidly to emergent safety-critical requirements. The estimated contract value is £20 million, although no contract duration or fixed delivery timeframe is stated. Work is centred on the WAGR complex at Sellafield in the United Kingdom, with the scope also allowing support to wider Windscale programmes and other emergent operational requirements. The critical requirement is the ability to work safely in Beta Gamma contamination facilities while managing radiological hazards and LLW/ILW in accordance with site requirements.

From the official notice
WAGR Overview and Site Information The Windscale Advanced Gas-cooled Reactor (WAGR), commissioned in 1962, was the prototype for the UK's second-generation Advanced Gas-cooled Reactor (AGR) fleet. The facility (Building B50), recognised by its distinctive spherical containment shell, was supported by the fuel assembly building (B52) and turbine hall (B55). Following reactor core dismantling and removal in 2012, the WAGR Complex entered Care and Maintenance (C&M). The facility is now progressing towards its final phase of decommissioning and demolition. Existing records confirm the presence of Low-Level Waste (LLW) and Intermediate-Level Waste (ILW), resulting in ongoing radiological and contamination hazards. All buildings within the WAGR area are owned by the Remediation operating unit, remain under active surveillance and maintenance, and are classified as Beta Gamma contamination facilities. Project Scope The scope comprises enabling, strip-out, waste management and decommissioning support activities across the WAGR facility, alongside support for wider Windscale decommissioning programmes and emergent operational requirements. Key activities include (see attachment) - Strip-out Works: Internal and external removal of fixtures, fittings, equipment and non-structural elements to facilitate future decommissioning and demolition activities. - Radiological Waste Management: Safe handling, removal and management of LLW and ILW in accordance with site requirements. - Asset Reins...
