Costain has been appointed to adopt the front-end engineering design for Urenco’s excessive assay low enriched uranium (HALEU) complicated fuels facility.
The brand new facility, to be constructed at Urenco’s Capenhurst website in Cheshire, will produce the specialist gasoline to give a boost to the improvement and deployment of the following technology of nuclear reactors.
HALEU is uranium that has been enriched to have between 5% and 20% of the fissile isotope, U-235. It’s had to gasoline the following technology of reactor designs, together with complicated modular reactors (AMRs) and small modular reactors (SMRs).
Costain is predicted to finish the FEED in 2027, informing Urenco’s plans for its new complicated gasoline enrichment applied sciences and manufacturing facility.

The fee follows Costain’s variety by means of Urenco previous this 12 months as programme supply spouse for Urenco Capenhurst infrastructure over the following 3 years.
Sam White, managing director, herbal assets at Costain, mentioned: “This extremely thrilling venture will identify the United Kingdom as the primary nation in Europe to release a high-tech complicated nuclear fuels programme, confirming its standing as an international chief within the civil nuclear power marketplace.
“Making sure the United Kingdom’s provide of complicated nuclear gasoline can be essential for powering the following technology of reactors, together with AMRs and SMRs. Those are nuclear applied sciences that can play crucial function as low-carbon resources of electrical energy to give a boost to a protected, resilient and decarbonised power device in the United Kingdom.
“Our knowledgeable engineers will paintings collaboratively with Urenco and the broader provide chain to design a state of the art gasoline facility. Constructability can be on the center of the designs to make this idea a fact.”
