Would it have been different if PIPCo handled things?

The interesting thing, I thought, was that foreign experts were brought in to help, and their judgment was that the situation is a lost cause and the best that can be done is to try to stymie the flow of underground water from seeping into the ocean, but that there really wasn't any good way to do that, so um, don't eat the seafood.

I don't understand why the Japanese get their panties in a bunch when a nuclear powered aircraft carrier docks at a US naval base but is ignorant about Fukushima...

Ok, I'm confused. I read an article last night before I went to bed that said they were thinking about breaking TEPCO apart and spinning off the division responsible for the cleanup. If anything, that sounds like a punishment, but I admit that my interpretation abilities may have sucked at the time I read that...

I normally wallow in bad news or really any kind of negativity like an over heated pig in shiatty mud but this mess has gotten too bad. I'm just going to into denial about it.

and they lived happily ever after

Don't worry, everything up until now will be but a footnote should this operation go wrong:
http://www.reuters.com/article/2013/08/14/us-japan-fukushima-insight -i dUSBRE97D00M20130814
"(Reuters) - The operator of Japan's crippled Fukushima nuclear plant is preparing to remove 400 tons of highly irradiated spent fuel from a damaged reactor building, a dangerous operation that has never been attempted before on this scale."

And here's the fun part:

""There is a risk of an <b>inadvertent criticality</b> if the bundles are distorted and get too close to each other," Gundersen said."

From that article:  "Spent fuel rods also contain plutonium, one of the most toxic substances in the universe, that gets formed during the later stages of a reactor core's operation."

I think that deserves a citation.

DrGunsforHands:
"....Gundersen said."

Oh, Gundersen.  He's a well known anti-nuke flake.

As long as there's a sufficient boron content in the water, there can be no criticality.  Period.  It just can't happen.  Boronating the water is easy, and in fact, they might have already done it (I'm not up on what spent fuel pool water typically is like, or if they boronated the water at Fukushima.).

Removing spent fuel is no more dangerous than unspent fuel.  The assemblies look and handle the same, just spent ones are more radioactive.

If anything, clearing out unit 4's fuel pool should be pretty easy (most of the fuel there is old anyway).  It's getting the corium out from units 1, 2 and 3 that'll be more interesting, especially if any of those units had lower vessel head failures (they're pretty sure 1 and 2 didn't, they've not said anything about 3 and from the stuff I've heard reported, I'm guessing they DID fail the vessel in unit 3).  Even still, it's just Three mile Island's cleanup on a somewhat larger scale - they're going to flood the area, then jackhammer out the stuff.

What these scare mongers never tell you is that the danger drops literally every  second.  The heat output is dropping off, the radiation levels are dropping off, etc.  As far as trying to 'shut down' the reactors - they've been shut ever since the earthquake - they are not 'out of control' or anything like that.  They're just lumps of corium sitting either in the reactor vessels or the containment (as i suspect unit 3's core is).  Solid lumps of stuff that's just giving off a decent (but always decreasing) amount of heat, and shedding some cesium in the process.  The configuration basically precludes any additional criticality.  None of the indicators of an ongoing reaction (i.e., iodine, short-lived gasses, etc) are there.

That's one way of putting it. Still, I agree with your analysis provided TEPCO isn't lying through their teeth about what is really happening there.

Maybe they should just drop a hydrogen bomb on it from orbit. Only way to be sure.
