The EFINOR group has signed major contract for the Hinkley Point C EPR

In October 2017, EFINOR signed the contract for the design, manufacturing and installation of the 2 main control rooms, the simulator and the six adjacent rooms of the 2 units at the Hinkley Point C EPR, at Bridgwater in Somerset for EDF Energy Nuclear New Build (NNB).

This New Engineering Contract valued at £ 20 million has been awarded to the consortium EFINOR & CLEMESSY, the EFINOR group will take the lead of the contract which will covers 4 years of design studies, 4 years of manufacturing and 5 years of on-site erection and will create job opportunities in France and the UK. EFINOR is in charge of the design, installation, testing and commissioning works for the steel structures and layout. CLEMESSY is in charge of the design, installation, testing and commissioning works for the electricity / monitoring & control package. This project allows CLEMESSY Nucléaire to gain a foothold in the nuclear market in England and to launch the development of the subsidiary CLEMESSY UK.
As a global project provider EFINOR’s extensive supply chain and subcontractors will be used to deliver this project. EFINOR Limited will be a key player in delivering the project with office strategically positioned in Bristol, close to the Hinkley Point C site and NNB offices.
Thanks to an extensive experience and knowledge of mechanical and seismic studies, project management and manufacturing for the Nuclear Industry, the consortium between EFINOR and CLEMESSY has already designed, manufactured and installed the Main Control Room on the Flamanville 3 EPR. EFINOR was a key supplier on Taishan EPRs Main Control Room. These major nuclear projects won by EFINOR and CLEMESSY bilingual and multicultural work teams have strengthened their skills and knowledge which are key-values on the HPC project.

About EFINOR EFINOR group is a combination of 3 business units: Engineering – Manufacturing – and Support, all involved in metal working from design to manufacturing and installation. This organization enables the group to provide global end to end services. Our know-how is relying on the consistency of our teams inside EFINOR and also on the proximity of our workshops and design offices all over France and in the UK. 30% of EFINOR turnover comes from the nuclear industry. EFINOR is a key subcontractor of EDF Energy, NNB, AREVA, BYLOR (JV between Bouygues and Lang O’Rourke) and other major nuclear contractors, EFINOR has manufactured the liners for the ITER site (new build project of the world's largest tokamak, a magnetic fusion device that has been designed to prove the feasibility of fusion at a large-scale and carbon-free source of energy based on the same principle that powers our Sun and stars*) and has collaborated with EDF for the creation of the multiple-elements mechanical plug OBTOPLUS® (EDF patent, EDF trade mark). It is aimed to seal pipelines or to bypass fluid in order to perform pressure tests without any structure alteration. OBTOPLUS® resists against high pressure through 40 bars (580 Psi).
▪ With 600+ collaborators, the EFINOR Group’s turnover, in 2016, was 52 million euros.
Fabrice LEPOTIER, founder and president of the EFINOR Group « I appreciate that good relationship between France and the UK goes really well, thanks to the confidence brought by our customer, NNB, on our capacity to perform such a major project, regarding our previous expertise on the French and Chinese EPR projects. I also wanted to thank all my teams for the quality of their work and the efforts they gave during these 4 years of business relationships ».
Within the Energy division of the Eiffage Group, CLEMESSY designs, improves, installs and maintains systems and equipment in the fields of electrical and mechanical engineering, in numerous sectors of activity: industry, energy, tertiary and transport infrastructure.
Its wealth of experience, combined with a constant search for innovation, has allowed it to develop expertise geared to many industrial processes.
CLEMESSY boasts over 40 years’ experience in the nuclear field and is involved in the entire fuel cycle. Its commitment to continuous positions today makes the company a reference partner offering know-how and expertise which meet the requirements and challenges of the nuclear industry.
▪ With a workforce of 5,000 employees, Clemessy achieved a turnover of 665 million euros in 2016.
« It has been a pleasure working with EFINOR/CLEMESSY on the tender phase. NNB appreciates the support the consortium is providing in addressing the erection challenges of this project while capitalizing the OPEX from FA3 and Taishan EPRs. The Consortium is a good example of the collaboration NNB is seeking to establish with the HPC suppliers. »
