Why Nuclear?

There is a lot more than 110 metric tons of fuel rods onsite..

Probably an equal amount in the cool down pool.
Another 2 to 3x in dry storage.. (6 to 8X for most US facilities).

Not even close. But what percentage would really be carried aloft? A
mushroom cloud is only a small fraction of the material at the plast site.
Why do you think it would be a disproportionate amount of spent fuel in the
cloud?
I don't care what you believe.

All one needs to observe is a typical mushroom cloud that forms
after such an explosion.

Destruction of the reactors primary and secondary containment in
the first couple of milliseconds would be a given. Just how the
failure mode progresses after that is an unknown.. My guess, reactor
probably spits it guts(core) out into the plasma ball surrounding
what's left of the facility.

And your 'guess' is based on???

Concrete structures actually stand up pretty well to the blast effects
(review above ground tests and the two nucs used in WWII). To 'vaporize' a
two foot thick containment wall, you would have to get the tactical weapon
much closer that 1/4 mile. Or if you speculate use of a thermonuclear
device, then the question is why a nuc plant and not Manhatten. So
distruction of the primary containment is *not* 'a given'.

Side note:

We'll find out after the first terrorist Nuclear strike on such a
facility. After that, our questions will be answered and I suspect
that ALL Nuclear power plants will BE DECOMISSIONED shortly thereafter.
(I.E. The ability to prevent a re-occurance would NOT be feasible,
thus deemed as an unacceptable risk.)

Pure unsupported speculation. How close to the reactor are you speculating
this weapon? How does it get that close past security and radiation
detectors? The owner controlled area of most plants is several city blocks
in size. If a tactical nuc can only damage a couple of city blocks, then it
would have to get past security to be within a 'lethal' radius of the
reactor.

Doesn't matter. Non-nuclear missiles (or simply bombs) with dirty warheads
will do more damage, more easily, than blowing up power plants. So it
still comes back to protection of the spent fuel.

I'd have thought that a blown-up nuclear power plant was itself the ideal dirty
bomb.

And what is your background??
I don't see a purpose to your non-specific request.
It's much easier to have a rational argument with someone who can cite
facts. Since you either can't or won't, you've merely made a statement of
what you believe - and as you said, yourself, "I don't care what you
believe".

Spent fuel.. There is a lot of it laying about US installations. (20
to 30 years worth).

Doesn't answer the question, "What percentage would really be carried
aloft?" And of that carried aloft and spread over 'three or four states',
what would be the concentration on the ground and in the environment in that
land area? How does that concentration compare to background radiation
levels and dose? I suspect you have *not* done the math you claim you have.
Otherwise you wouldn't be making such outlandish claims of
death/destruction.
My previous posts only factored in the contents of the Reactor itself.
(Which will be operating at full power when the event occurs. )

What do you think the current operating power level has to do with anything?
Or do you just mention it to try and scare the masses into thinking its
somehow relavent. Considering plants operate at full power about 90% of the
time, it's hardly a stroke of genious to assume an attack would happen while
at power.

Do you think that is the plant's most vulnerable condition?

^^^^^^^^^^^^^^^^^^^ (1/4 of a mile)..
There dozens of ways to deliver a N-weapon right NEXT to the
containment.. (Especially, if they have smart(human) guidance system.
I don't think terrorists have a problem with that aspect.)

Really? Dozens? Name three.

A human with a device walking into a facility would be stopped at the
security entrance. This is more than 1/4 mile from the containment in most
plants. His device would set off several different alarms. Someone trying
to gain access via other than authorized access points faces a number of
formidable barriers. Attempting to breach such barriers is now instantly
considered a threat to the general public and deadly force is authorized to
stop anyone making such an attempt. (I wonder if the 'greenpeace' folks
that tried such things in the 70's and early 80's would try them today)

No ground-based vehicle can get that close either (despite your citation
below that is completely outdated). Guess that leaves airborne threats.
Well, maybe that's one. But 'dozens of ways'? Now you're just trying to
use scare tactics and fearmongering.
Yes, (see above.) Total destruction..

Manhattan, You kill a few hundred thousand, maybe 1/2 million.

or

Take out Nuclear plant when wind blowing towards food growing
and population centers.

Kill a smaller number outright.
Take out three or four states for the next 1000 years.
Create ten's of millions penniless of refugees..
Decrease their average lifespan by 5 to ~10 years.
(economic ruin/poverty is just as deadly as radiation.)
(assumes evac will be 100% successful & permanent)
Economic loss 3 to 5 times that of GDP.
(Equivalent to 24 to 40 million deaths.. @ 1M$ of GDP per person
lifetime.)
Cripple the country with huge re-occuring burden.

Unsupported claptrap. Even if a nuc plant were attacked, the likelyhood of
your scenario is more remote than even you could calculate. Even if as much
radioactivity went airborne as you claim, the affects on the land-use and
people you claim are unsubstantiated. Look at how 'uninhabitable' the area
around Chernobyl is today just 20 years later. Activity might be
*detectable* over the entire continent. But *detectable* and
*uninhabitable* are a far cry from each other.

Ten tactical nucs set off in the largest US population centers would have
worse effects and would be easier to carry out (not that it would be
'easy'). Yet you seem to be implying that ten nucs at nuclear plants is a
more credible threat. Despite the stronger security, you think a terrorist
would rather go after a hardened, secure target than the superbowl stadium
in front of live TV? or a presidential inaugaration?
Almost any approach path in excess of XX meters will do.
By sea, land or air. Anything method that avoids the front gate.

Most of those detectors aren't designed to detect N-weapons.
They sample the air stream for airborne radioactive particles.

Guess you've never had to enter a nuclear plant. Radioactive air samplers
are used for detecting the *release* of radioactive material, not *security*
of incoming personnel/equipment. Different things, different purposes,
different methodologies.
N-weapons aren't designed to deposit any significant materials into
the atmosphere until they go off.


(Two city blocks), 1056 ft @ 20 mph.== about 36 seconds of warning and
time to deploy counter measures without setting off the weapon.

Only if a vehicle could maintain 20 mph through whatever barriers may be
installed for the purpose of *not* allowing it. Do you think you're smarter
than the security experts that protect these facilities? You think you're
the first person to think of this? How large an ego do you have??
I won't go into details for obvious reasons..

Nor will I discuss the details of nuclear plant security in detail (I am not
privy to all the security details either). But your idea of plant security
is outdated and grossly oversimplified. Much of your scenario depends on
nuclear plant security being as lax as it was 30 years ago. It isn't. You
really think you're the only one that ever thought of these threats? Such
hubris.
Getting past security is a no-op.
Delivering weapon with 20ft of containment is a no-op.

Saying it doesn't make it true. It merely shows your ignorance and lack of
analytical thought.
A few years back(93), an escaped hospital patient drove a station
wagon through TMI-1's turbine building's alumium roll up door and
stopped inside. (Within ~200ft of reactor containment).

http://www.nrc.gov/reading-rm/doc-collections/gen-comm/info-notices/1993/in93094.html
http://www.dep.state.pa.us/newsletter/?varQueryType=PrintVersion&NewsletterID=217

It took them four hours to find the intruder in the basement of the
turbine building.

You really have a pretty low esteem of the whole nuclear security process to
think security remains unchanged after such an incident. The reason you
were able to find that incident in the NRC documents is because when that
event occurred the NRC required each licensee to review and update their
security plans. Several more updates have occurred since then and since
9/11. The NRC allows that incident to be public knowledge and not
classified because they no longer believe such a scenario is a danger. Do
you really think the NRC would publish a 'blueprint' of how to attack a
facility on their own web if that hadn't eliminated that threat ??? Notice
the date of the event and the date of the publication. The public document
was released only *after* corrective actions were taken to prevent a
recurrence.

You are ignorant of the security at nuclear sites, and assume it hasn't
changed in decades. That really is pretty stupid. But it suits your agenda
of fear-mongering, so you do it anyway.

You claim to have insider knowledge of nuclear weapons capabilities and
understandably are reticent to discuss them. Yet you think you are aware of
all security measures around nuclear plants, that such security is detailed
in the public record and that security measures remain unchanged after
incidents. Guess you don't see the irony in that.

Except that 'dirty' bombs are designed to spread contamination, while
nuclear plants are designed to contain it.

Why? because the tremendous investment requires huge concentrations of
power which the egos involved like to be on top of. The concentration of
power at a single point also concentrates the *money* that pays for it. As
the number of sources of power decline, the profits of those who are
incontrol of those sources increase.

The 'base line' consumption assumes that power from remote wind turbines
can not be brought in to an area where the wind is not blowing. You may
see a day where the wind dont blow, but nobody sees a day where it dont
blow in lots of other places.

As for wind being a threat to birds; they will figure it out. Those that
cant stay out of the way will be filtered out of the gene pool. Darwin
will solve that problem in a few years.

At the end of the day, the Almighty Dollar decides. The amortized cost of
new wind turbines is falling below $0.04/kwh, well below nukes. Dont ask
the givernment if nuclear power is a good idea, ask Wall Street.

Then too, while alcohol from corn looks like a scam, there are other crops
that are far more efficient with far lower costs of production and output
well in excess of 100 gallons/acre. Crunch the numbers; the average
midwest county is 25x25 miles. Even if only 50% of a county was in alcohol
production, that'd be 20 *million* gallons of alcohol/year.

And that's just one county. Never mind the meat production that comes from
feeding livestock the left over mash.

When the lights go out and people are burring up, Nuclear fission might be
the only alternative to fill the gap, it seems like Fusion is going to take
a much long time getting here or it might get here when Wallstreet can make
money off of it..

Wow. There's an Americocentric viewpoint. I'd say that all of them face

No, really that's the _only_ important consideration. As somebody else
pointed out, blowing up nuclear plants is rather pointless if you can just
target cities. How to safely store the spent fuel is the problem.
Why not ship the spent fuel to Antartica? Course, the Greenland ice cap
is closer, and if that all melts, we'll have more pressing problems.

But the problem of another American Nuke remains- that of a terrorist
attack, and the obvious inability of the administration to imagine what
means the Jihadim might come up with to accomplish that.

And just what home improvement center is selling home nuclear fission

It's whatever we discuss. You just said that "These other countries you
cite dont face nearly the risk of terrorism", when clearly they do.
Pakistan has faced far more terrorist bombing than the US.

In fact, the thread originated with a UK poster, so it can hardly be assumed
we're talking only about American plants. As I said - Americocentric.

There are any number of "reasonably" safe alternatives, but little political
will to deal with them. The big problem is that the half-life of the
problem elements is a great deal longer than the political-life of those
who have to deal with it. Whether we decide ever to build more nuclear
plants, the issue still has to be solved - the waste already exists.

You don't actually need fission - the solution to disposal of nuclear waste
is right there: just ship it out to homeowners in quantities sufficient to
boil water :) You can get heat and electricity from it.

The only people I read here, or see in the media that are freaked about
nukes are Americans. I'm not saying that the anti-American rhetoric in
Pakistan or wherever is undeserved, but there's good reason to think
that America is the richest target... with the most inept leadership to
prevent it.

Well then, why doesnt everyone in all countries ship the spent fuel to
Antarctica? Is there something else they plan to do with the place? If
it stays frozen in barrels of water, then it stays out of ecosystems;
and if it ever melts while there, we'll have LOTS of other problems.

Because it would require political will, which is always in short supply.
It's far easier for politicians to leave it for somebody else to deal with.

Technically, it would be darn hard to keep radiating waste from melting
water, so merely dropping it under the ice cap wouldn't keep it stationary.
Recent studies show there _is_ liquid (flowing) under the ice cap, so it
would likely just sink a few thousand feet and seep into that flow. Then
there's the security issue - much worse than the actual storage issue. I
expect most countries would prefer to keep their nuclear waste where they
can (they hope!) control access to it.
