2008 under CEA to provide a vehicle for international assistance. Its purpose is to help to set up structures and systems to enable the establishment of civil nuclear programs in countries wanting to develop them and will draw on all of the country's expertise in this. It is guided by a steering committee comprising representatives of all the ministries involved (Energy, Foreign affairs, Industry, Research, etc) as well as representatives of other major French nuclear institutions including the CEA itself and Institute for Radiological Protection & Nuclear Safety (IRSN). Its work will be confined to countries with which France has signed a nuclear cooperation agreement, among the 40 countries which have sought assistance from France. It will function on a fee for service basis
 
Economic factors
France's nuclear power program cost some FF 400 billion in 1993 currency*, excluding interest during construction. Half of this was self-financed by EdF, 8% (FF 32 billion) was invested by the state but discounted in 1981, and 42% (FF 168 billion) was financed by commercial loans. In 1988 medium and long-term debt amounted to FF 233 billion, or 1.8 times EdF's sales revenue. However, by the end of 1998 EdF had reduced this to FF 122 billion, about two thirds of sales revenue (FF 185 billion) and less than three times annual cash flow. Net interest charges had dropped to FF 7.7 billion (4.16% of sales) by 1998.
* 6.56 FF = EUR 1 (Jan 1999)
In 2006 EdF sales revenue was EUR 58.9 billion and debt had fallen to EUR 14.9 billion - 25% of this.  EdF early in 2009 estimated that its reactors provided power at EUR 4.6 cents/kWh and the energy regulator CRE put the figure at 4.1 c/kWh.  The weighted average of regulated  tariffs is EUR 4.3 c/kWh.  Power from the new EPR units is expected to cost about EUR 5.5 to 6.0 c/kWh.
From being a net electricity importer through most of the 1970s, France has become the world's largest net electricity exporter, with electricity being the fourth largest export. (Next door is Italy, without any operating nuclear power plants. It is Europe's largest importer of electricity, most coming ultimately from France.) The UK has also become a major customer for French electricity.
France's nuclear reactors comprise 90% of EdF's capacity and hence are used in load-following mode and are even sometimes closed over weekends, so their capacity factor is low by world standards, at 77.3%. However, availability is almost 84% and increasing.
Reactor engineering and new build
The first eight power reactors were gas-cooled, as championed by the Atomic Energy Authority (CEA), but EdF then chose pressurised water reactor (PWR) types, supported by new enrichment capacity.
All French units are now PWRs of three standard types designed by Framatome - now Areva NP (the first two derived from US Westinghouse types): 900 MWe (34), 1300 MWe (20) and 1450 MWe N4 type (4). This is a higher degree of standardisation than anywhere else in the world. (There have been two fast reactor - Phenix which ran for over 30 years, and Super Phenix, which was commissioned but then closed for political reasons.)
