The Fukushima-1 Reactor at Daiichi is a General Electric BWR-3 design with Mark I containment. It turns out that the Boiling Water Reactor at Oyster Creek, New Jersey, is an almost identical design: BWR-2 with Mark 1 containment. Oyster Creek is the oldest operating commercial nuclear reactor in the US today.
Here's a very, very pretty picture of Oyster Creek.
The above is from a University of New Mexico archive of fascinating drawings of nuclear power plants from around the world, which will make almost any nuclear engineer drool. You can get the full pdf of Oyster Creek here.
In particular (I think you need the full pdf to see the detail), note the location of #14 (the spent fuel pool), #6 (safety valve -- this is probably what they used to burp the reactor), and #27 (the recirculation pump, which is what's keeping the water circulating and core cool right now).
Fukushima-1: 460 MWe, initial criticality in October 1970.
Oyster Creek: 619 MWe (it's been uprated a few times), began operation on December 23, 1969.
