The region hosts two important Nuclear power plants. At Flamanville there is the Flamanville Nuclear Power Plant. The other is the COGEMA La Hague site. It is a large nuclear waste reprocessing and storage complex operated by Areva NC. The nuclear power industry provides many jobs in the region. The roads used for transport of nuclear waste have been blocked many times in the past by environmental action group Greenpeace. Local environmental groups have voiced concerns about the radioactivity levels of the cooling water of both these nuclear sites. These are being flushed into the bay of Vauville. However, the radioactivity is much lower than the natural background levels and does not pose any hazard.
