Virginia US Earthquake - Nuclear Plant

[tsutsuji]

Among the points raised by the Group of Concerned Scientists and Engineers Calling for the Closure of the Kashiwazaki-Kariwa Nuclear Power Plant after the 2007 earthquake at Kashiwazaki-Kariwa, one question was whether "the force applied exceeded the elasticity limit of the materials of equipment" ( http://cnic.jp/english/topics/safety/earthquake/kkscientist21aug07.html ). Even if there is no apparent damage, if the elasticity limit has been exceeded, the metal might have become more brittle and would not resist a future earthquake as well as fresh new metal coming right down from the furnace. I guess similar questions could be asked, or rather, I hope, have already been asked and given a satisfying answer, concerning the Virginia earthquake.

That sounds like 99% enriched weapons-grade-baloneyum to me.
