Nuclear Disaster Unfolding In Fukushima Options

This getting worse every day

The timing of this disaster in Japan was a perfect distraction from the re-rommelization of North Africa.

One thing that i wondered about, was the way the water was dumped from helicopters on the reactors...

If the object was to "top up" the water in the cooling ponds, why did so much of that dumped water miss the building?
Poor piloting?
No.
Was it to cool the rods blasted from the building from the giant explosion?

(they sprayed wtc for a long time after 9/11, too)
Water cools nuclear reactions.

Why did Japan change the names of the reactors after the accident?

cpm, rems, radioactivity...

Not only is it invisible but the different methods of measuring it, make it difficult to understand something that one does not want to stand under.
They are now putting up new radiation detectors all along the west coast of N.A. Both Canada and US.

All the potassium iodide pills are withheld from the public, and have been stockpiled by government here in BC, and there was a run on health-food stores, for kelp concentrates.

Was it to cool the rods blasted from the building from the giant explosion?

To be honest, yeah this is a possibility at the No3. We cannot exclude it given how the building in detail looks like after the explosion from the photographs.

But the whole thing would become really dangerous not just locally only in a case the rods would start to burn, which can't happen even if they would not be cooled by water from above -if they're dispersed around - because the cooling by air would be then sufficient to prevent this to happen by wide margin - Oxide fuels can't start to burn (I mean only the Zirconium clading-Water reaction, which in larger assemblies would be maybe able to melt the fuel if it occurs, but not in a case of isolated fragments - and solid Zirconium alone can't catch fire itself under its boiling point of 4409! °C, Uranium and Plutonium oxides can't burn at all !) - if they wouldn't have a temperature of 900+ °C - nothing like that we see even remotely at the thermal images from the plant, where the maximum temperature seen was 128 °C at the top of the No 3 reactor primary containment -which is very expectable temperature at PWR given the inside pressures. The risk which this could pose - if the rods were ejected from the pool, which to be honest I think could be the case - is more like it could considerably hamper the efforts of the rescuers there, because making the suroundings having considerably higher dosage readings close to such fuel fragments, which I think - if it is the case - should first be meticulously gathered and put into shielded secure containers to considerably lower the overal possible dose (of gama and also because they could further release the gaseous radionuclides, posing internal contamination risk) at the compound and make the rescue efforts considerably less dangerous for the brave workers at the site.

I think the hysteria of utter nonsenses about the MOX fuel -the activists started with after they realized no new Chernobyl would happen at Fukushima- just show the pathetical desperateness of this fearmongering disinfo efforts. The Plutonium oxide has the boiling point way above 2000 °C so the possibility the Pu-239 and especially the even more immediately dangerous Pu-241 and Pu-238 would be released into the environment in significant amounts is extremely low and in fact it didn't much happened even in the Chernobyl, where the core experienced nuclear explosion, containing at the moment very considerable portion of Plutonium isotopes from the U-238 transmutation - however also in the oxidated form with very high melting (2400 °C) and boiling (2800 °C) points. -just to avoid confusion a metal Plutonium has the boiling point even higher (3228 °C - which hardly can occur even in the melting reactor core - without boiling it the volatility of Plutonium is close to zero and without melting it IS zero).

I hope this helps to cool down the fears.
