RE: abc news on nukes-terror targets; containments magically grow
Norm,
And the anti-nuke folks have been able to publish about millions of pounds
of jet fuel on aircraft even though a 747-400 has a maximum take off weight
of 875,000 pounds. If you believe every thing you read, you're a fool. And
while I'm not a structural engineer, I'll bet real money that the thickness
of a containment building does vary from building to building, and even
within the same building (I'll bet they're thicker at the bottom).
Flame me in private,

Subject: abc news on nukes-terror targets; containments magically grow
NRC says they are ready, can't say how.
Radsafers, with friends like the NRC, you don't need UNPLUG Salem. ;-)
