Our Achievements


EPC fluides package for the experimental reactor Jules Horowitz, CEA Cadarache (France).


Our teams of experts in the nuclear sector have were tasked with the EPC Fluids package for the Jules Horowitz Nuclear Research Reactor (RJH). This work includes the secondary, tertiary and emergency cooling systems as well as the production and distribution of utilities.

This project involves our specific know-how in the nuclear market: piping, boilermaking, mechanics, EIA, radiological protection, and handling equipment.

We have designed, studied and produced packages of fluids in compliance with nuclear safety rules comprising 46 cooling and utility systems, 20 km of piping, 4,000 valves, 1,300 items of equipment (pumps, exchangers, filters, tanks, etc.), 250 tonnes of supports, etc.

Our teams have been mobilized to 25,000 hours of engineering, 520,000 hours of assembly and relations with 100 suppliers and subcontractors.

The Jules Horowitz (RJH) research reactor project, led by the CEA's Nuclear Energy Department, responds to an essential scientific and technological challenge: testing the behavior of materials and fuels under irradiation, in support of current nuclear reactors and future. 

This reactor is a unique experimental irradiation tool in Europe available to the nuclear industry, research organizations, as well as nuclear safety authorities and their technical support.
