EDF (France)
EDF are launching a substantial industrial programme : to operate the nuclear power plants beyond 40 years and increase the power capacity of the reactors with enhanced safety and in line with the regulatory framework.
Within this context, Clemessy, as part of a consortium of companies, won the contract for the General Electrical Installations (GEI) for several power plants, the work on which is scheduled to last until 2020.

AREVA NP (France)
Within the framework of the renewal of the steam generators for the 900mW reactors, the engineering, removal and refitting of the General Electrical Installations and Site Electrical Installations. AREVA awarded CLEMESSY with a first contract, concluded in 2005 for the refurbishment of  8 reactors over a period of 8 years and they have recently renewed their faith in us by awarding a second contract for a further 8 reactors over a 7-year period.

EDF (France)
Supply contract for 40 speed regulation boards controlling the emergency diesel generator sets for the 1300 and 1400 MW units.
Within the framework of this project, Clemessy handles the job of monitoring the remanufacturing of parts which are identical to the original ones, in line with the obligations regarding Quality and Safety imposed by EDF for this type of equipment.

EDF (France)
Engineering and bringing into compliance the hydrogen tightness circuit for the P’4 and N4 a.c. generators. This operation is aimed at protecting the facilities with regard to the risk of an explosion linked to hydrogen.

EDF (France)
Within the framework of a consortium of companies, carrying out the Flamanville 3 EPR site’s Electrical Surveillance Installations: the site’s video surveillance, access control and security equipment.

EDF UTO (France)
Requalification in workshop of the pilot a.c. generators for the CP0 / CP1 unit of the French nuclear power plants.
22 rotors have to be requalified over a period of 4 years.
These a.c. generators coupled to the turbo generator set provide the emergency power supply for the turbine’s safety and regulation systems.

EDF (France)
Since 1985, within the framework of a consortium of companies, Clemessy have been handling the implementation of the instrumentation and the maintenance of the 1300 and 1400 MW power plants.
