[quote:Anonymous Coward 1295673:MV8xNTM3MTQ2XzI5Njc0Mjc4XzdFN0Y1RkMw] U.S. nuclear plants similar to Fukushima spark concerns http://www.cnn.com/2012/02/17/us/us-nuclear-reactor-concerns/index.html [snip] Arnie Gundersen, a former nuclear engineer and a leading critic of the Vermont Yankee plant, says the Japanese accident shows the Mark I containment system can't prevent a release of radioactivity in a meltdown. In an October hearing before the NRC's Petition Review Board, he said [b]the vents were a "Band-Aid fix" for the design that failed "not once, not twice, but three times" at Fukushima Daiichi.[/b] "True wisdom means knowing when to modify something and knowing when to stop," said Gundersen, who leads a state commission set up to monitor the Vermont Yankee plant. ~ CNN is citing Arnie. They don't go into it, but what he is talking about is the test done 40 years ago on the vessel that showed that the containment cap bolts would stretch at pressures over 100psi, allowing containment gases to escape. This is what allowed the hydrogen gas to escape containment and build up inside the reactor buildings at Fuku, thereby causing the explosions. Tepco said it was a failure to vent in time that caused the hydrogen build up. ~ bug [/quote]
