From: King, Mark Sent: Friday, April 01, 2011 7:49 AM To: Telson, Ross Subject: FYI NRC Says US Plants Are Safe. China’s Xinhua (4/1, Regencia) reports that NRC spokeswoman Viktoria Mitlyng said “that the plants in Illinois, in other states, and the rest of the country are safe,” and have “stringent design requirements to begin with.” She added, “Each nuclear power plant has to be able to withstand natural disasters such as earthquakes, tornadoes, floods to the highest level that is historically known in that area, plus a certain margin.” So do the Japanese plants.., but since 2007 they have been shown to not have the necessary “certain margin”.., in one case (2007 earthquake event) it resulted in a 7- unit multi-year unit shutdown (with some plants experiencing g forces 5 times greater than predicted; 3 of the 7 units are still shutdown but luckily few direct safety issues came out of that event). And in this most recent case the “certain margin” was also vastly exceeded – plants were designed apparently for a 5.6 meter tsunami… but apparently had a 14.5 meter tsunami at the site. Only off by a factor of….- 2.6 ! Hopefully our “certain margins” for flooding / earthquakes, etc. … are better figured in the US. What do you think? It always concerned me that Japan and China were building nuclear units in some of the most earthquake (and resulting tsunami induced) prone areas of the world.
