The framework is expected to see contracts awarded to Costain over a minimum of three years and will see Costain lead and deliver an integrated programme for Urenco’s infrastructure investment activities.

Urenco’s Capenhurst site provides uranium enrichment services to produce fuel for civil nuclear power stations in the UK and around the world to generate low-carbon electricity.

The site is undergoing a series of complex work programmes to support the long-term resilience of the site, including establishing Europe’s first High Assay Low Enriched Uranium (HALEU) advanced fuels facility.

Costain will work closely with local supply chain partners and provide strategic direction, integration, assurance and governance of the works.

Sam White, managing director, natural resources at Costain, said: “Ensuring the supply of safe, low-carbon electricity is critical for creating a sustainable future.

“We’re bringing decades of experience in predictable, best-in-class delivery to help safeguard the UK’s energy security and support the transition to more sustainable energy generation.

“Costain has a strong presence in the North West and this award reinforces our commitment to improving the lives of local communities through the provision of new jobs, developing skills and driving prosperity.”
