USA’s worries about its nuclear reactors similar to Fukushima’s

U.S. nuclear plants similar to Fukushima spark concerns By Matt Smith, CNN
February 17, 2012   — As the United States prepares to build its first new nuclear power reactors in three decades, concerns about an early generation of plants have resurfaced since last year’s disaster in Japan.
The Vermont Yankee nuclear power plant — the subject of a battle between state authorities and the Nuclear Regulatory Commission over its continued operation — uses one of 23 U.S. reactors built with a General Electric-designed containment housing known as the Mark I.
It’s the same design that was used at Japan’s Fukushima Daiichi nuclear power plant, where three reactors melted down after the station was struck by the tsunami that followed Japan’s historic earthquake in March 2011. The disaster resulted in the widespread release of radioactive contamination that forced more than 100,000 people from their homes…..
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 the vents were a “Band-Aid fix” for the design that failed “not once, not twice, but three times” at Fukushima Daiichi.
“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.
Half of U.S. reactors are more than 30 years old…..    http://edition.cnn.com/2012/02/17/us/us-nuclear-reactor-concerns/?hpt=us_c1
