Nuvia, Ovivo win contracts for Hinkley Point C

11 July 2017

EDF Energy has recently awarded two new contracts for work on the Hinkley Point C EPR project in Somerset, UK.

International nuclear engineering firm Nuvia has won a £20 million contract from EDF Energy to design and build the Nuclear Sampling System (NSS) for Hinkley Point C.

The NSS is used to determine the physical-chemical properties of liquid samples to ensure they comply with water quality requirements for the primary circuits and steam generators.

The system has four main functions: pre-conditioning of the liquid samples, online chemical analysis, offline sample collection within gloveboxes and laboratory analysis.

Nuvia is responsible for the scheme and detail design, procurement, manufacture, factory acceptance testing, installation and commissioning of the NSS.

Work started in June 2017 and will be delivered over a six-year period, the firm said.

The NSS contract is Nuvia’s third EPC contract for the Hinkley Point C project. It is also providing the Primary Circuit Boron Recycling (TEP) and the Secondary Effluent Treatment system (TEU) in partnership with Rolls-Royce.

Cooling water intake contract for Ovivo

EDF Energy has also awarded Essex-based Ovivo UK Limited a £27million contract to design and supply the cooling water intake screening system for Hinkley Point C. 

The system, which EDF Energy claims will be the largest cooling-water intake-screening system in the world, will process more than 191 cubic meters per second, for cooling the electricity generating steam-cycle and the EPR technology used at HPC.

“Once installed, the drum screens will be the largest screens of their type in the world, with a diameter of 27m by a width of 6.84m, approximately 30% larger than its closest rival,” EDF Energy said.

Ovivo’s scope of work includes the design, fabrication, delivery and technical support during the erection and commissioning of the system. The project will run for eight years and will be delivered mainly from the Colchester office of the SME, which employs nearly 100 staff in the UK.

Humphrey Cadoux-Hudson, EDF Energy’s Managing Director for New Nuclear Build, said the contract “represents another important step in engaging the UK supply chain."

In June, Cadoux-Hudson told the NIA’s Nuclear New Build Forum that EDF Energy was “on track” to award 64% of construction contracts to UK companies.
