This is GROSSLY off topic but i think you would be amused to find out that GE design was much more solid than it may looks like. Each Fukushima reactor building was build with a panel designed to fall down in case of earthquake. Aaaaaand Japanese welded them shut after they did exactly that after few minor earthquakes. So, when big one happened hydrogen gas accumulated and exploded.
Why they did that? Local population was unhappy when they saw holes in reactor buildings.
Definitely off-topic, but . . . That's incorrect. You seem to be referring to the building blowout panels, which are supposed to "blow out," of course, to relieve pressure inside the building. In the emergency, hydrogen built up inside the reactor buildings, but with insufficient pressure to release the panels. Here's a good explanation by the Japan CNIC (yes, they're an anti-nuke organization, but they know what they're talking about):
