Under Revised Quake Estimates, Dozens of Nuclear Reactors Face Problems

mdsolar (1045926) writes "Owners of at least two dozen nuclear reactors across the United States, including the operator of Indian Point 2, in Buchanan, N.Y., have told the Nuclear Regulatory Commission that they cannot show that their reactors would withstand the most severe earthquake that revised estimates say they might face, according to industry experts. As a result, the reactors' owners will be required to undertake extensive analyses of their structures and components. Those are generally sturdier than assumed in licensing documents, but owners of some plants may be forced to make physical changes, and are likely to spend about $5 million each just for the analysis."

Re:Must question the "revised" estimates

Arguably no estimate is adequate. Unexpected things happen, and our understanding and knowledge of the tectonic plate system is incomplete anyway. Given the risk we should be designing for safety in the most extreme event possible. Look at it this way: the fact that the estimates were revised up tells us that the original estimates were too optimistic, there is at least some chance that the new ones are too.

The cost is always going to be proportional to the risk. That's why no commercial insurance company will offer any nuclear facility insurance.
