FACTBOX-Key facts on Areva's EPR nuclear reactor

Dec 9 (Reuters) - France's Areva CEPFi.PA has staked its export growth on the EPR reactor and is hoping it will beat American rival Westinghouse to become the standard-bearer for a new generation of plants.

But delays in building nuclear reactors, cost overruns and design concerns could undermine plans by the world’s largest nuclear reactor builder to grab a leading share of the global atomic energy renaissance.

Here are Key facts on the EPR:

* A third-generation reactor designed by Areva and German industrial group Siemens SIEGn.DE, it can resist the impact of an airliner, according to its manufacturers.

* The water-pressurised reactor has a capacity of 1,650 megawatts (MW), around 150 MW more than the most recent reactor model built in Chooz (northeastern France) and Civaux (southwestern France).

* It has a technical life span of 60 years and is designed to use 17 percent less uranium to produce the same quantity of electricity as previous models.

* Maintenance operations on the reactor will be shorter because of better access to equipment.

* The reactor was initially called European Pressurized Reactor. The name was changed two years ago to Evolutionary Power Reactor, to give it a more international dimension, but is now simply called EPR.

* The first examples of are currently under construction in Finland, in the French northern nuclear site of Flamanville and in southern China.

* An EPR costs around 5-6 billion euros.

* Areva currently hopes to export its EPR to Britain, the United States, India, Italy, and the United Arab Emirates.
