The BWR concept was developed slightly later than the PWR concept. Development of the BWR started in the early 1950s, and was a collaboration between General Electric (GE) and several US national laboratories. Research into nuclear power in the US was led by the three military services. The Navy, seeing the possibility of turning submarines into full-time underwat… WebEnglish: Rough sketch of a typical Boiling water reactor (BWR) Mark I Concrete Containment with Steel Torus including downcomers, as used in the BWR/1, BWR/2, BWR/3 and some BWR/4 model reactors. * DW = Drywell * WW = Wetwell * SFP = Spent Fuel Pool * RPV = Reactor Pressure Vessel * SCSW = Secondary Concrete Shield Wall concrete coverage per yardWebThe BWR Mark I has a primary containment system comprising a free-standing bulb-shaped drywell of 30 mm steel backed by a reinforced concrete shell, and connected to a torus-shaped wetwell beneath it containing the suppression pool (with 3000 m 3 of water in units 2-5).
