Summary of the contracting process

The procurement process managed by Nuclear Waste Services involved a tender titled "Sellafield Calder Primary Circuit," focused on radioactive waste treatment services. This contract, designated under CPV code 90521000, pertained to managing waste from the Calder Hall Blower Houses and was executed through a selective procurement method, specifically a call-off from a framework agreement. The procurement, located in North West, United Kingdom, effectively transitioned from award phase to contract commencement on 31st July 2026. The total contract value stands at £1,775,908.20, with the contractual engagements stretching until 2nd October 2031. The process, classified as a service contract, culminated with an award to Augean South Limited, following the tender period's conclusion on 23rd January 2026.

This contract represents a significant opportunity for businesses specializing in waste management and radioactive waste treatment to engage with Nuclear Waste Services. Firms operating within the environmental services sector, particularly those familiar with handling and treating hazardous waste, could find this contract to be a lucrative growth opportunity. Large enterprises or well-established organisations equipped with the necessary expertise and operational capacity to manage significant waste treatments would be well-positioned to compete effectively in this industry segment, even as SMEs and VCSEs are not seen as suitable in this instance.
