The progress in terms of civil engineering at the end of 2011 is 88%, and that of electromechanical assemblies is 21%.
EDF has opted for EPR technology to prepare for the future of electricity generation from a nuclear source.
Environmental, technical and economic objectives. With regard to current units, the EPR project's principal objectives are to reduce the volume of radioactive waste and emissions; in the area of radiation protection, to halve the collective annual dose compared with the current average level for units in operation in France; to achieve an availability of 91% through design principles from German reactors which allow generation during maintenance operations; and to achieve, from the design stage, a technical operating life of 60 years.

Flamanville 3 project: the first marketable generation target is set for 2016, with estimated construction costs of around 6 billion Euros(2008). Flamanville 3 is the first nuclear power plant to be built in France for 15 years. Its target construction time is 100 months.
A reservoir measuring 450 km2.
A high-voltage, 138 Km long transmission line to Thailand
The Nam Theun 2 dam in Laos has been commissioned in May 2010. Hydropower is the main form of renewable energy generated by EDF. This project, a major commitment for the Group in Southeast Asia, mobilized over 9,000 employees at its height, of which more than 80% were Laotian.
EDF has fully exercised its role as architect and lead contractor, from design and supplier selection through to building and operating the facility. The Nam Theun 2 power plant is located on a tributary of the Mekong River and represents a major contribution to the development of Laos, as well as a source of energy for the northeastern quarter of Thailand. Indeed, this region will be the main beneficiary of the electricity generated by the plant’s six turbines.
1,5 million homes supplied with electricity
A 19 Km long gas line to supply the power plant
The construction of the two Taishan EPR reactors in southern China entered a new phase on Wednesday 12 September. Less than a year after the dome of reactor 1 was installed, the dome has now been installed on reactor building 2. A big step forward for a unique site.
Owner and future operator of the TNPJVC site - 30% of which is owned by EDF and 70% by its Chinese partner - the electricity company CGNPC, successfully installed the dome on the unit 2 reactor building. As was the case for installation of the unit 1 dome in October 2011, this large-scale operation called for one of the most powerful cranes in the world. This milestone marks the conclusion of the main civil engineering operations for the reactor building in which almost 2,000 people have been involved over 2 years. Now completed by its dome, the reactor building will be home to the heavy-duty components of the nuclear steam supply system (steam generators, vessel, pressuriser, etc.). The structure will be sealed by welding the whole dome, which will then be covered in 7,000 tonnes of concrete to increase its strength.
Taishan really is the site of sites. Two third-generation 1,750 MW reactors, for which AREVA is supplying the nuclear island, are being constructed simultaneously on a site measuring more than 800 hectares, on which the installation of six EPRs is planned: a world first! A tunnel 4 kilometres long was constructed to bring in water containing fewer sediments. A dam 250 metres wide and 55 metres high will be devoted exclusively to supplying the plant with fresh water. Currently, 10,000 engineers, technicians and other employees work in constant rotation seven days a week. Amongst them, some fifty EDF employees have been posted to TNPJVC to be a part of this incredible industrial adventure. Most of them are based on the site. They take care of design, construction, start-up test preparation and operation, as well as filling the support roles necessary for operation of the subsidiary. And let's not forget the four construction monitoring specialists who are based near to the plants where the main components of the two units are assembled.
