...BWRs...
...There are 35 operating BWRs located at 24 sites in the United States...
...They are designated Models BWR 2 thru 6...
...They are housed in Mark I thru III Reactor Containment Buildings...
...There are two Model 2s, 6 Model 3s, 19 Model 4s, 4 Model 5s and 4 Model 6s...
...The 2 Model 2s have 5 reactor coolant recirculation pumps, all others have only 2...
...The 4 Model 6s have spent fuel pools located outside the reactor containment building, all others have spent fuel pools located in the reactor containment building...
...There are 23 Mark I (torus) reactor containment buildings housing Model 2s, 3s and 4s.
...There are 8 Mark II (suppression pool-vertical standpipe) reactor containment buildings housing Model 4s and 5s.
...There are 4 Mark III (horizontal vent) reactor containment buildings housing all 4 of the Model 6s.
...The Mark I and Mark II reactor containment building drywells, torus/suppression pools are nitrogen inerted. The Mark IIIs are not.
...The oldest operating BWR is Oyster Creek (BWR 2, Mark I, 650 MW, 1969).
...The newest operating BWR is Limerick 2 (BWR 4, Mark II, 1191 MW, 1989).
...The first commercial power BWR was Dresden 1 (210 MW, 1960 - 1978).
...If you like, I will email you the first chapter of my book "American Nuclear Power Plants" which contains the information listed above. The information originally came from the 2008 American Nuclear Society World List of Nuclear Power Plants.
