Are you sure it is a nuclear power plant? Looks more like a coal powered one, because of the large coal field little north of the plant. Those cooling towers are very normal for watercooling at any powerplant.
Sorry dear, you are here in Charleroi! There isn't any nuclear site there... Tihange is the Nuclear centrale of HUY, near Liege...
