Fukushima unit 2 liquification of uranium core. never seen before in history of nuclear power

Unit 2 we now know completely liquified. We’ve never seen this before in the history of nuclear power. A 100% liquification of a uranium core.

[TXnMA]

Liquifaction (if it did occur) was only a transient phenomenon -- probably within a day of the initial accident.

Criticality (if it did occur) has long since been quenched by "dilution" of the corium with things like melted concrete, etc.

The largest source of heating was decay of short half-life fission products -- and they are long-since decayed.

BOTTOM LINE: the worst-case occurred, it passed, we survived it, and now temperatures are down below the boiling point of water.

Learning to read is highly recommended...

And that’s a bad thing, right?

Not if it comes with a free Frogurt.

Unless the Frogurt is also completely liquified!

There will be no remediation possible; resulting in radiological contamination of underground water-ways (interacting ocean and fresh-water aquifers) within this entire region, for hundreds-of-thousands of years.

Would you say it's time to crack open your neighbor's skull and feast on the goo inside?

Maybe in your overwrought sensitivity, you ought to phone up Screen Gems and have them scrub all those McHale’s Navy episodes.

Boron will "poison" the reaction and quench it so that the core will stop melting itself. Properly designed Boron catch pans will contain an entire melted core until it solidifies, and will keep it immobile and stable.

That bit of information would have come in very handy ending Hanoi Jane's career about thirty years ago...

I don’t believe that any bona-fide nuke operators or objective physics jocks are laughing here, but they’re not running around in circles, yelling “Repent, the end is near!” either.

I, for one, welcome our new ant overlords.

Anybody smart enough to know what the ramifications are?

This is something new for us humans. Unchartered territory. Been following this from the beginning and originally I was middle of the road concerning nuclear power. Saw the positives and the negatives. Unfortunately, now think the negatives far outweigh the positives. Primarily because of the stupidity and corruption of the people charged with handling and preventing these accidents. Mankind does not have enough integrity to properly operate and manage these early nuclear designs. And to think Obama wants Iran to have nuclear power plants. Yeah. Great idea.

At any rate, back to the ramifications. Go to the thread linked above at ex-skf. Read those comments. Some were mine. Also read the comments on the Enenews thead. Some were good. I never ever commented there.

Personally have no intellectual respect for Kaku at all. He bought into that global warming is gonna kill us idiocy, hook, line and sinker. Now what was interesting with his comment, is that #2 apparently experienced 100 % meltdown. Do not know his specific source. Sounds like it might be a news feed or email list that is only for the well connected. No public info backing up his claim yet. Prior to that, Tepco had stated around 50-60 % meltdown of unit #2. Could go into the implications of a 100 % liquification with respect to #2, but quite frankly, if what I suspect happen, actually happened, you may not want to know. The truth will come out in time, until then, be a prepper.

Nobody doesn't like Molten Boron!

Fingers crossed!

Now you are asking all posters to actually read the linked article and absorb it? Jeeze the traditions of this website are daily being done away with and we are going to hell-ina-handbasket.

I suppose the next thing will be that we have to stay on topic?

Before long, we are going to have to have Onyx, Humblegunner and Laz certify every post before it uploads to the thread?

” Boron will “poison” the reaction and quench it...”

20 Mule Team Borax to the rescue!

I don’t know if this is “bad enough” though.

With respect to Tokyo and most of Japan, there is a mysterious black soot or dirt appearing in cities near Fukushima and Tokyo. We suspect right now its origin is from the steam fissures around the Fukushima plant. You only occasionally see the steam when its concentration is thick enough. Normally it is too thin to be seen. It contains very fine particles from the soil, Fukushima material disintegrating and corium. It is traveling and depositing all over Japan and soon the West coast US. Its is highly radioactive with numerous hot particles. Japaneses citizens are breathing that into their lungs, right now. Basically they have created an extra fine corium debri field all over Japan. And this is just the beginning of the crisis.

Please note - The above is all IMHO. So take all this with a grain of salt or a tincture of iodide.

[justa-hairyape]

The RPV’s are immaterial at this point in time. 3 core meltdowns. 3 RPV’s that no longer serve any function, except that they are caps to giant blow holes. The information we actually need, is not attainable or is classified. IE - The locations of the corium masses.

May just have to move back Oklahoma ....

[TXnMA]

How about iodized (sea) salt..."

(BTW, I hope you are not deluding yourself into thinking the "corium" or any of the radioactive materials at DaiIchi are still in a liquid or vapor state...)

[Mr. Jeeves]

think it means it’s no longer in the corium ‘blob’ state but capable of traveling into the earth’s mantle in a stream-like state; which is much worse than any previous worst case scenario.

So vacationing to the Earth's mantle is no longer the safe family weekend getaway it used to be? :)

In all seriousness, it's time to retire the current generation of plants and move forward with thorium reactor technology. It really should have been done decades ago.
