Costain cements position as key partner in the nuclear supply chain

6 November 2023

  • New contract to deliver support across eight nuclear power stations
  • Two-year contract worth £15m/yr with option to extend

Costain has won a two-year contract to deliver a project controls managed service across EDF’s eight UK nuclear power stations. The contract will see more than 150 specialists provide expert advice and support across the portfolio. 

As part of this new contract, which is worth £15m a year and has the option to be extended, Costain will continue to develop and grow EDF’s core project controls capabilities, and provide specialist support to improve project performance and deliver cost efficiencies. 

Within the highly regulated, safety-critical civil nuclear sector, Costain is managing over 400 projects in EDF’s programme, regulated by the Office for Nuclear Regulation. We are supporting EDF to maintain and improve operational station availability, maximise station output and safeguard supply.  The work also includes supporting EDF on its transition from generation to defueling of the Advanced Gas Reactors. 

Costain has been working with EDF since 2017 when it was first awarded the Project Controls Framework to support the safe operation and decommissioning of the UK’s existing nuclear power stations.  

Bob Anstey, defence and nuclear sector director at Costain, commented,  

“We’re delighted to continue our successful relationship with EDF. We’re reducing plant risks within this highly regulated environment by providing well over a hundred specialists to support the management of complex and interdependent programmes and projects. This, in turn, supports Nuclear Plant Life Extension and we’re proud to be playing our part in the ongoing operation of the UK’s nuclear power generation.”
