Nuclear plants

On its territory is installed the seaside Flamanville Nuclear Power Plant, established there in the 1980s, with two PWR reactors of 1300 MWe each, which were put into operation in 1986 and 1987.

Flamanville has been selected for the installation of the first French EPR reactor, which will be Flamanville's third reactor, near the two existing ones. Whether or not Flamanville 3, EPR, actually becomes operational is political, as many prominent politicians are opposed to it.

There are also plans for later fourth reactor.
