France's nuclear construction programme has changed significantly in recent years. After the setup of units having outputs of 900 and 1 300 MW with three or four units per plant, the current programme is reduced to one unit of 1 400 MW every four years until the year 2 000 and even beyond, depending on the life of the plants presently in service. The present article focuses on the Chooz B plant: - overall project, - reactor building, -coolants, - turbine building (and its structural steelwork)
