Flamanville, nuclear plant (European pressurised water reactor model)

Missions

Working on behalf of the Contractor, setec  drew up the reinforcement drawings for the entire plant on the basis of guide drawings prepared
by EDF, adapting them to the Contractor’s methods and phasing. The drawings comply with Eurocodes and EDF’s specific requirements.

“The success of the Flamanville site is essential and will benefit the entire French nuclear industry as, throughout the world, this technology is now recognised to be an innovative, safe and competitive solution”.
Pierre Gadonneix, EDF CEO
The European pressurised water reactor model (EPR) is a third generation nuclear reactor with a 1,650 MW capacity. The first construction of this type of reactor began in Finland in 2005. The construction of the Flamanville EPR aims to extend the nuclear skills of EDF which plans to start up over
6,000 MW of additional electricity production capacity by 2012 in France.
Safety requirements led EDF to provide the following for the EPR: a double concrete containment vessel with a metal liner to ensure that the reactor building is fully sealed; a core catcher installed under the reactor vessel in case of a major accident; and an aircraft crash shell surrounding the nuclear
buildings to protect the plant from the impact of an airliner.
At its peak, over 2,000 people will be workingon the site. The works are scheduled to take 54 months and will concern 20 buildings
including: the reactor building which will be protected by a double prestressed
reinforced concrete shell; the fuel building where new and spent fuel will be stored; the machine room containing the turbine generator; and the pumping and discharge stations which cool the plant with seawater.

Challenges

The number, size and complexity of the works forming part of the Flamanville EPR led Setec tpi to use up to a maximum of 150 employees working in four international teams (France, Egypt, Morocco and Tunisia) to produce the 5,500 working drawings needed for the 20 buildings forming the Flamanville EPR within a four year period.
