What's the most at-risk U.S. nuclear power plant?

Could it happen here? That's the question on everyone's mind as we watch the nuclear emergency unfold at Japan's Fukushima Dai-ichi nuclear plant. As it turns out, the U.S. government has long been asking the same question.
The Nuclear Regulatory Commission recently provided MSNBC with an updated list of the American plants most at risk of core damage (which can lead to meltdowns and radiation release) in the event of an earthquake. What parts of the country are most at risk? You may be surprised.
Most people would assume California plants, built around the turbulent San Andreas fault line, might be in the most dangerous position. Actually, the most at-risk plant isn't even on the West Coast - it's on the Indian Point Energy Center Hudson River.

Indian Point, located in Buchanan, N.Y., has the highest risk of core damage in the event of an earthquake, according to NRC estimates reported by MSNBC. At a 1 in 10,000 chance of core breach, that's right on the verge of what the NRC calls "immediate concern regarding adequate protection."
The East Coast comes off much worse than other parts of the country. The second plant on the list is Pilgrim 1 in Massachusetts. Number three is in Pennsylvania. The only West Coast plant is Diablo Canyon in California at number nine.
What explains it?
The government's list considered how close the plants were to major fault lines and how well they were designed to handle an earthquake. Back in the 1960s and 70s, when most of the plants were built, the government knew about earthquake risks on the West Coast. Those plants were designed to withstand them. But new surveying technology has revealed fault lines in the central and eastern states where plants were not designed for the serious stresses of a large quake.
That's turned the risks upside down. California plants now seem relatively safer, according to the government estimates provided to MSNBC, and East Coast plants, once deemed at low risk, have jumped to the top of the list.
It is important to note the list refers to core damage, not a meltdown. But as the University of Georgia's Cham Dallas, director of the Institute for Health Management and mass Destruction Defense, explains, "core damage can lead to water loss which can lead to a meltdown."
Testifying before House panel Wednesday, Energy Secretary Steven Chu said, "The American people should have full confidence that the United States has rigorous safety regulations in place to ensure that our nuclear power is generated safely and responsibly. Information is still coming in about the events unfolding in Japa, but the administration is committed to learning from Japan's experience as we work to continue to strengthen America's nuclear industry. Safety remains at the forefront of our effort to responsibly develop America's energy resources, and we will continue to incorporate the best practices and lessons learned in that process."

However, the magnitude 9 earthquake caused a very large tsunami, which did not dissipate much energy over the short distance to the Fukushima site.
I think when determining potential damages to USA nuclear sites, this has to be kept in mind. Many of our nuclear sites have a fairly probable potential for a stronger earthquake than that experienced at the Fukushima, and hopefully none are subject to tsunami damage. It is very difficult to separate the risks, but it's a worthy attempt nonetheless, assuming someone can be found who is both qualified and has no ax that gets ground in the process. That is probably more difficult than surviving the Japan tragedy.
A lot has been blamed on the tsunami knocking out the emergency generators that are necessary to keep the reactors cool following the earthquake damage. However, I saw a post by a nuclear consultant, who claimed that USA emergency generators often fail power-up tests. Somewhere between minor unreliabilities to actually breaking up rendering the generators permanently useless. In one test, three generators actually broke after inspectors demanded a test because the power plant operators were too lazy. I've been involved with such generators at non-nuclear facilities ..... you can't depend on them without regular tests.
But I too, have opinions ...... and I think that if we are not smart enough to keep nuclear power plants out of tsunami zones, we are probably not smart enough to have the things in the first place. Does coal do us any better? I don't know ..... all the coal slag and airborne particulates can't be doing us any good. I guess we wait for the day that we grow enough morals and ethics to objectively study such things.
Perhaps more troubling, Indian Point is a sitting duck a mere 25 miles from the worst terror attack ever to take place on American soil. Entergy has an excellent and effective public relations campaign; pumping vast amounts of money to placate both politicians and populace. Even environmental organizations like nearby Historic Hudson Valley have accepted hundreds of thousands in Entergy donations. Look at the agony in Japan - their largest cosmopolitan city on the brink of poisoning. Look at the parallels right here in our region. Would it not be better to take our heads out of the sand and quickly decommission this obsolete and hellacious threat in an orderly way? The sacrifice would be small in comparison to the potential consequences. Murphy's law, if it can it will.
NRC here takes wait and see approach, hope its not wait and see an earthquake and wave
I'm thinking maybe it is.
Of course it could happen!

sad the senate is at the edge of safety, but lack the balls to demand the NRC temporarily shutdown the ocean, high risk zone plants
