I found an interesting report on nuclear plants' ability to withstand an aerial attack. Very informative, brought up points that I hadn't considered or read about before.
http://www.gsenet.org/library/11gsn/2001/gs010919.php I am referring to the second article on the page.
The first one is a rather touching reflection on the WTC destruction.
very eye opening article about the vulnerability of nuclear reactors. they mention that even though the reactor core may withstand a hit by an airplane, if control facilities are damaged a meltdown could ensue. and the holding ponds with spent rods would make quite a "dirty bomb"
thanks for the post
