Tepco puts on a fresh brew

From Kaye in Kobe.

paul, have you heard of anything about this??? we don’T know anything… here, no media cover the story on this…. we need info…..

The Tokyo Electric Power Company (TEPCO) says radioactive steam has suddenly begun emanating from previously exploded nuclear reactor building #3 at the Fukuishima disaster site in Japan. TEPCO says they do not know why this is happening and cannot go into the building to see what’s happening due to damage and lethal radiation levels in that building. Experts say this could be the beginning of a “spent fuel pool criticality (meltdown)” involving up to 89 TONS of nuclear fuel burning up into the atmosphere and heading to North America. Steam photo, full details and suggested methods to protect yourself appear below.

On December 28, 2013, the Tokyo Electric Power Company (TEPCO) admitted steam was seen billowing out of reactor building #3, saying the steam appeared to be coming from what’s left of the fifth floor of the mostly-destroyed building. It is widely known that persons cannot get inside Reactor Building #3 because it is severely damaged and highly radioactive, so TEPCO cannot state for certain what is happening in that building or why. TEPCO admits they do not know why this steam is being generated, but matter-of-factly revealed today (December 28) the steam was first spotted on December 19 for a short period of time, then again on December 24 and again on December 25.

Nuclear energy experts have told TRN that the ONLY way this could be happening is if radioactive material previously ejected from the reactor explosion in March, 2011 has mixed together with other materials and has begun its own self-sustaining reaction(s), also known as a “criticality.” Put simply, another “meltdown” may be taking place.

There are basically two possibilities if another meltdown is in progress:

1) Pellets of radioactive fuel, ejected when the reactor exploded, have mixed together and “mini” meltdowns are taking place with those small clumps of pellets. This would not be a horrific problem and may be manageable, OR;

2) Pellets of radioactive fuel, ejected when the reactor exploded, went into the spent fuel pool located above the reactor and have begun melting down so seriously they are boiling off the water in the spent fuel pool.

Since steam is visible, experts tell TRN that Scenario #2 above is is the most likely scenario and if so, it would be an absolute nightmare — WORSE than the original Fukushima disaster! The Spent Fuel Pool was situated on the fourth floor above Reactor #3, and if this is the source of the steam, the situation could escalate rapidly out of control.

My answer to Kaye in Kobe is this:

So steam is not unexpected when hot corium meets water.

Remember the arguments over using seawater in the Fuk reactors in the early days? It wasnt just about wrecking the reactors. Adding water would increase fission rate. And it did.

Ask your friendly local GE sales person. After all, in March 2011 GE stated that it would “stand by its customers”. That’s the people of Japan and the world. Anyone heard from em lately

I would suspect its corium and water , which is why I think they built the place there – as some sick emergency cooling to minimise the size of the spreading fuel lava. Have passed it on to a nuclear engineering fellow Kaye.

I believe they did not choose that site for no reason. Its implied in the Ergen report that certain situations minimise the size of the molten core. At various costs to the environment of course.

THOUGHTS ON NUCLEAR PLUMBING

keeping the corium as small as possible is their idea of “all A OK, here”. “I’m not worried about Fukushima”: Lake Barrett.

Too bad about the steam and environmental poisoning of land sea air and life. Have a banana.

The hydrology of Fukushima has long been known and was probably in my opinion chosen as a source of emergency coolant should the arse drop out of the reactors as predicted by the GE 3 who lost their jobs in t
he 70s.

Steam? ” Oh goodie, time for coffee” Lake Barrett. (not really but he is “not worried”.

Pity noone knows where is the molten cores are.

For 60 years they told us they knew everything. And those who disagreed were communists.

phuck em. Cold shut down. Remember that? Measure the places where the fuel was not and say “hunky dory” or whatever that is in nuke speak.

Water tables, to these idiots, are the core cooling systems of last result. Which is why Lake Barrett is “Not concerned about Fukushima” Typical nuclear crap.
from their point of view keeping the nuclear lava cool is a good thing. Pity about the steam but.

corium behaviour in differing materials:

1. Size of Molten Sphere in Various Soils 1
To illustrate the magnitude of the decay heat release from a 3,200Mwt
core in terms of the heat capacity of several common materials, the
size of a molten sphere containing one-hour-aged fission products was
calculated using dry sand and limestone as the heat absorbing material.
The model for this calculation assumed that the molten material in the
sphere was all at the melting temperature – 3,133 degrees F for dry sand and
4,4600 degrees F for limestone – and had the same density as the surrounding
material so that no settling or floating of the sphere would occur.
Conduction heat transfer from the sphere was included on the basis of
infinite medium surrounding the molten sphere. Fig. 1 shows the sphere
radius as a function of the time after shutdown for dry sand and limestone
as heat sink materials; the sphere radius for the adiabatic – i.e.
no conduction – condition is also shown for dry sand. These results
indicate that molten spheres of approx 60 ft diameter for limestone and
approx 90 ft diameter for dry sand would be required to absorb and dissipate
the decay heat from a 3,200 Mwt core. Also the growth of a molten sphere
would continue for a approx 20,000 hours under these conditions.”

From the mad nuker view the wetter the better, except that water is a neutron moderator. More water, more fission, more heat, more need for cooling, more nuke lava. The nuclear devil’s balance they do not talk about because they have not got a technical fix. Apart from feeding it to the fish. And People. And insects etc. The biosphere, it was a nice place once.

Then Groves took the apple Szilard offered him.

And said it was perfectly safe and there was no fallout in Japan.

Some people will believe anything.

As you can tell this is all getting so bloody blatant, I’m sick of it. But then, I’m down here in the Bolt Holt. It’ll get here.

Sooner or later.

Unless Barry’s idea of the little plastic bags is correct. Which it isnt. And he knew it when it told that town hall full of school kids.

Didnt you Barry.

I reckon they deliberately placed the joint where it was so that they could in emergency divert the ground water to the reactor basements to aid cooling.

Prove me wrong Barry Brooks. Smart arse.
