"There is a place for nuclear newbuild in the world, but less than before," Kocher said at a Le Monde seminar.

She said that in Europe and the U.S. there were few economies of scale in nuclear newbuild because so few new reactors are being built.

Engie has a 40 percent stake in the NuGen consortium to build three Westinghouse nuclear reactors in Cumbria, Britain. Toshiba has 60 percent in that consortium.

It is also part of a consortium to build a nuclear plant in Turkey.
