France will build a second new-generation nuclear reactor, President Nicolas Sarkozy said Thursday, pledging a "new industrial revolution" in an era in which fossil fuels have grown too expensive. France - the country most reliant on nuclear power - has been constructing its first European Pressurized Reactor, or EPR, on the Normandy coast, and it is expected to go into service in 2012. EPR reactors are meant eventually to replace the aging reactors around the world whose designs date from decades ago. The Normandy site is one of only two EPRs in the world currently under construction; the other is in Finland. A decision about where to build a second French EPR will be made in 2009, Sarkozy said, adding that construction would start in 2011. "The era of inexpensive oil is over," Sarkozy said. "Nuclear power is more than ever an industry of the future, and an essential form of energy."
