Actually, we might all have been wrong, and Dan the "least wrong" (I won't say "correct" Dan since you didn't mention any of this <grin>). Mountainboy, is there a nuclear power plant in Oak Ridge? For some reason, I can't find a definitive answer to that.
I don't know why it didn't register before, but we're all thinking of a commercial, nuclear power plant like Three Mile Island. So, we're all concentrating on "nucular plant" but forget the other part. The name "Oak Ridge" includes a lot of different stuff. There's Oak Ridge National Laboratory, there are WWII era uranium enrichment facillities (the "K-25 Building"), and the current Y-12 National Security Complex. I'm sure there are other facillities there. Y-12 is a nuclear weapons production facility.
So, Mountainboy, depending on what you're actually referring to, the risk is going to vary. I doubt any terrorist wants to attack Oak Ridge National Lab because they just do research and they don't have any fissionable materials there. Y-12 on the other hands, must be full of weapons-grade plutonium and highly enriched uranium.
OBG was mentioning how the nuclear security teams always kick butt at competitions, which I found surprising. I usually only hear stories like
this or
this or
this about their security. Besides, the Dept of Energy, or the private security firms that DOE hires, don't seem like the kinds of jobs that the really good high speed, low drag types would want to join. Where's the glamour? Actually, that DOE "red team" in the Time article sounds like a cool job.
