Better build a bunker, Chicoms are building two new breeder reactors which produce plutonium

China Is Building Two Secret Nuclear Reactors. Scientists Are Worried:

 

Why would China be stockpiling plutonium behind closed doors? “China is presently engaged in a large nuclear weapons build-up that U.S. intelligence officials publicly estimate will result in at least a doubling (or more) of the size of Beijing’s nuclear arsenal,” the experts explain, and accumulating plutonium gives them even more of these critical resources.

Bet You Didn't Know Japan Has 44 Tons Of Plutonium

I didn't either.

Story here:

Japan now has 9 tons of plutonium stockpiled at several locations in Japan and another 35 tons stored in France and the U.K. The material is enough to create 5,000 nuclear bombs. The country also has 1.2 tons of enriched uranium. ...

It also has plans to open a new fast-breeder plutonium reactor in Rokkasho in October. The reactor would be able to produce 8 tons of plutonium a year, or enough for 1,000 Nagasaki-sized weapons.

Is the Plutonium Story Being Sensationalized?

To read the online papers, like ABC News (here), you'd think the detection of plutonium around the Fukushima reactors indicates a meltdown is suddenly underway, as if nothing has been happening since the quake and tsunami struck on March 11, 17 days ago, and radiation subsequently began to pour out of the facilities.

Yet the reports from Japan are not wholly satisfactory, evidenced by speculation about a direct correlation between the problems at reactor 3 (where plutonium is an ingredient in Mixed OXide fuel) and what has been found in the soil.

Kyodo News likens the amounts detected in the soil to amounts routinely found during the era of atmospheric testing of nuclear weapons before the Test Ban Treaty (here):

[T]he levels confirmed from soil samples taken at the plant on March 21 and 22 were almost the same as those from the fallout detected in Japan following past nuclear tests by the United States and Russia, said the utility known as TEPCO.

And NHK World has perhaps a slightly different angle (here):

[T]he level detected is the same as that found in other parts of Japan and does not pose a threat to human health. ...

The Nuclear and Industrial Safety Agency says the detected level is the same as that found in the environment and not health-threatening for workers who conducted the sampling, nor residents in surrounding areas.

The question is whether the plutonium traces found are the normal residue from the era of atmospheric testing, are otherwise normal traces unrelated to that time, or are related to a problem at reactor 3.

Additional testing is said to be underway.

Meanwhile, if it bleeds, it leads.

Japan Admits Radiation at Fukushima is Deadly: 4,000 mSv Per Hour

Ten times worse than a previous report, and over 7.5 times the normal lifetime average total exposure of 483 millisieverts, and all in one hour.

The UK Daily Mail has all the details and photos, here, but most pointedly, this:

The boss of the company behind the devastated Japanese nuclear reactor today broke down in tears - as his country finally acknowledged the radiation spewing from the over-heating reactors and fuel rods was enough to kill some citizens. ...

Unlike the other reactors which use uranium, Reactor 3 uses a mixture of uranium and plutonium. Plutonium, best known as an ingredient in nuclear weapons, is particularly dangerous if released into the environment. In the worst case scenario, exposed fuel will melt, triggering a chemical explosion that will send radioactive dust hundreds of yards into the air. Chinook helicopters flying at less than 300 feet dropped four loads of water over the wrecked building in the hope that some water would seep into the dried-out pool and cool the fuel. However, footage suggested much of the 2,000 gallons of water missed its target. Later, six fire engines and a water cannon tried to spray the building with 9,000 gallons of water from high pressure hoses. However, radiation levels within the plant rose from 3,700 millisieverts to 4,000 millisieverts an hour immediately afterwards. People exposed to such doses will suffer radiation sickness and many will die.


We've been lied to all week while the media in America have been full of apologists for the nuclear industry, soft-peddling the seriousness of this situation.

Once in a Lifetime Emergency Dose of Radiation Emitted Hourly at Fukushima Reactor 3

The New York Times reports here about the high levels of radiation thrown off of reactor no. 3 at Fukushima I, the only plant reported to be using plutonium fuel:

Hidehiko Nishiyama, deputy director-general of the Nuclear and Industrial Safety Agency, said . . .

. . . that radiation of about 250 millisievert an hour had been detected 100 feet above the plant. In the United States the limit for police officers, firefighters and other emergency workers engaged in life-saving activity as a once-in-a-lifetime exposure is equal to being exposed to 250 millisieverts for a full hour. The radiation figures provided by the Japanese Self-Defense Force may provide an indication of why a helicopter turned back on Wednesday from an attempt to dump cold water on a storage pool at the plant.

Reports of much lower measurements at the gate to the whole complex may be meaningful in the context of relative measures of safety at various distances, but the reality is that these damaged reactors pose a deadly threat to human life and health.

Fukushima Reactor No. 2 Update: Did the Fire Engine Run Out of Fuel?

The UK Daily Mail has these details, reported here:

There were reports that a fire engine pumping water in to the Number Two reactor failed shortly before last night's explosion -- which would have led to an increase in temperature inside the reactor and could have caused the blast. ...


The latest explosion last night is feared to have cracked the main protective barrier around reactor number two at the plant.

The International Atomic Agency said radioactive material is leaking 'directly' into the air from the stricken plant at a rate of 400 millisieverts per hour.  Anyone exposed to over 100 millisieverts a year risks cancer.

Engineers are using sea water to cool overheating nuclear fuel rods.

That is a sign of the desperation of the situation because the corrosive salt water will put the reactors permanently out of action. It is the first time in 57 years that sea water has been used to cool a reactor.

Although the plant’s three working reactors shut down automatically when the magnitude nine earthquake struck on Friday, the cooling systems which keep the radioactive uranium and plutonium fuel rods cool have been hit by a series of failures. ...

'It is too dangerous to go outside and even if they did they would not be able to be transported to a safe place because we have no fuel for our vehicles,' [the mayor of Fukushima City] said.
