Meltdown and Melt through in March 2011, Industry Denial Until May/June 2011

If a nuclear authority wants to start a rumor mill so that the population can be accused of getting it wrong, lie and with hold information. Trouble with that is, that when the truth comes out, the population is shown to right and the alleged experts are shown up to be what they actually are.

In fact 3 reactors had experienced meltdown in March 2011.

Nuclear meltdown at Fukushima plant
One of the reactors at the crippled Fukushima Daiichi power plant did suffer a nuclear meltdown, Japanese officials admitted for the first time today, describing a pool of molten fuel at the bottom of the reactor’s containment vessel.

Engineers from the Tokyo Electric Power company (Tepco) entered the No.1 reactor at the end of last week for the first time and saw the top five feet or so of the core’s 13ft-long fuel rods had been exposed to the air and melted down.
Previously, Tepco believed that the core of the reactor was submerged in enough water to keep it stable and that only 55 per cent of the core had been damaged.
Now the company is worried that the molten pool of radioactive fuel may have burned a hole through the bottom of the containment vessel, causing water to leak.
“We will have to revise our plans,” said Junichi Matsumoto, a spokesman for Tepco. “We cannot deny the possibility that a hole in the pressure vessel caused water to leak”.
Tepco has not clarified what other barriers there are to stop radioactive fuel leaking if the steel containment vessel has been breached. Greenpeace said the situation could escalate rapidly if “the lava melts through the vessel”.

However, an initial plan to flood the entire reactor core with water to keep its temperature from rising has now been abandoned because it might exacerbate the leak. Tepco said there was enough water at the bottom of the vessel to keep both the puddle of melted fuel and the remaining fuel rods cool.
Meanwhile, Tepco said on Wednesday that it had sealed a leak of radioactive water from the No.3 reactor after water was reportedly discovered to be flowing into the ocean. A similar leak had discharged radioactive water into the sea in April from the No.2 reactor.
Greenpeace said significant amounts of radioactive material had been released into the sea and that samples of seaweed taken from as far as 40 miles of the Fukushima plant had been found to contain radiation well above legal limits. Of the 22 samples tested, ten were contaminated with five times the legal limit of iodine 131 and 20 times of caesium 137.
Seaweed is a huge part of the Japanese diet and the average household almost 7lbs a year. Greenpeace’s warning came as fishermen prepared to start the harvest of this season’s seaweed on May 20.
Inland from the plant, there has been a huge cull of the livestock left inside the 18-mile mandatory exclusion zone with thousands of cows, horses and pigs being destroyed and some 260,000 chickens from the town of Minamisoma alone. The Environment ministry has announced, however, that it will attempt to rescue the thousands of pets that were left behind when residents were ordered to evacuate. At least 5,800 dogs were owned by the residents of the zone, although it is unclear how many remain alive, two months after the earthquake struck.

If in doubt, ignore nuclear authority pronouncements, and just refer to Wikipedia: “In the hours and days that followed, Reactors 1, 2 and 3 experienced full meltdown.[9][10]”

While pro nuclear “Experts” held the field for months and months in the mass, and while the Japanese governments passed laws in an attempt to stop ordinary people discussing the issues in the public domain, World Nuclear in foreign lands was arrogantly dictating parroting what TEPCO and Japan’e “Ministry of Untruth” had already abandoned as unworkable lies weeks earlier.

3 nuclear reactors melted down after quake, Japan confirms
By the CNN Wire Staff
June 7, 2011 — Updated 0956 GMT (1756 HKT)

Tokyo (CNN) — Japan’s Fukushima Daiichi nuclear power plant experienced full meltdowns at three reactors in the wake of an earthquake and tsunami in March, the country’s Nuclear Emergency Response Headquarters said Monday.
The nuclear group’s new evaluation, released Monday, goes further than previous statements in describing the extent of the damage caused by an earthquake and tsunami on March 11.
The announcement will not change plans for how to stabilize the Fukushima Daiichi plant, the agency said.
Reactors 1, 2 and 3 experienced a full meltdown, it said.
The plant’s owner, Tokyo Electric Power Co., admitted last month that nuclear fuel rods in reactors 2 and 3 probably melted during the first week of the nuclear crisis.
It had already said fuel rods at the heart of reactor No. 1 melted almost completely in the first 16 hours after the disaster struck. The remnants of that core are now sitting in the bottom of the reactor pressure vessel at the heart of the unit and that vessel is now believed to be leaking.

A “major part” of the fuel rods in reactor No. 2 may have melted and fallen to the bottom of the pressure vessel 101 hours after the earthquake and tsunami that crippled the plant, Tokyo Electric said May 24.
The same thing happened within the first 60 hours at reactor No. 3, the company said, in what it called its worst-case scenario analysis, saying the fuel would be sitting at the bottom of the pressure vessel in each reactor building.
But Tokyo Electric at the same time released a second possible scenario for reactors 2 and 3, one that estimated a full meltdown did not occur. In that scenario, the company estimated the fuel rods may have broken but may not have completely melted.
Temperature data showed the two reactors had cooled substantially in the more than two months since the incident, Tokyo Electric said in May.
The earthquake and tsunami knocked out cooling systems at Fukushima Daiichi, causing the three operating reactors to overheat. That compounded a natural disaster by spewing radioactive material into the atmosphere.
Tokyo Electric avoided using the term “meltdown,” and says it was keeping the remnants of the core cool. But U.S. experts interviewed by CNN after the company’s announcement in May said that while it may have been containing the situation, the damage had already been done.
“On the basis of what they showed, if there’s not fuel left in the core, I don’t know what it is other than a complete meltdown,” said Gary Was, a University of Michigan nuclear engineering professor and CNN consultant. And given the damage reported at the other units, “It’s hard to imagine the scenarios can differ that much for those reactors.”

A massive hydrogen explosion — a symptom of the reactor’s overheating — blew the roof off the No. 1 unit the day after the earthquake, and another hydrogen blast ripped apart the No. 3 reactor building two days later. A suspected hydrogen detonation within the No. 2 reactor is believed to have damaged that unit on March 15. end quote.

‘Melt-through’ at Fukushima? / Govt report to IAEA suggests situation worse than meltdown
The Yomiuri Shimbun 8 June 2011

Nuclear fuel in three reactors at the Fukushima No. 1 nuclear plant has possibly melted through pressure vessels and accumulated at the bottom of outer containment vessels, according to a government report obtained Tuesday by The Yomiuri Shimbun.

A “melt-through”–when melted nuclear fuel leaks from the bottom of damaged reactor pressure vessels into containment vessels–is far worse than a core meltdown and is the worst possibility in a nuclear accident.

The possibility of the situation at the plant’s Nos. 1 to 3 reactors was raised in a report that is to be submitted to the International Atomic Energy Agency.

If the report is released as is, it would be the first official recognition that a melt-through has occurred.

It was revealed earlier that sections of the bottom of the pressure vessels where control rods go through have been damaged. Highly radioactive water from inside the pressure vessels was confirmed to have leaked out of the containment vessels, even outside the buildings that house the reactors.

The report also acknowledges problems with the vertical administrative structure concerning nuclear safety regulations. As a result, the report says, who was responsible for keeping people safe in the event of a nuclear accident was not clear.

The report proposes separating the Nuclear and Industrial Safety Agency from the Economy, Trade and Industry Ministry and making it an independent organization. The report also proposes drastic reform of the nation’s nuclear administration, including the Nuclear Safety Commission.

Vessel damaged 5 hours later

The pressure vessel of the No. 1 reactor at the Fukushima No. 1 nuclear power plant is believed to have been damaged five hours after the March 11 earthquake, according to an analysis by the Nuclear and Industrial Safety Agency.

The finding differs with a provisional analysis earlier released by plant operator Tokyo Electric Power Co., which stated the the pressure vessel was believed to have been damaged 15 hours after the March 11 Great East Japan Earthquake.

On Monday, NISA, a nuclear watchdog body run by the Economy, Trade and Industry Ministry, disclosed the results of a detailed analysis regarding damage at the Nos. 1 to 3 nuclear reactors at the Fukushima facility. NISA estimates that the No. 2 reactor’s pressure vessel was damaged 80 hours after the disaster. TEPCO’s analysis contends the No. 2 reactor’s pressure vessel was damaged 109 hours after the quake.

According to NISA’s analysis, the No.1 reactor’s core began suffering damage three hours after the earthquake.

The No. 1 reactor’s pressure vessel was damaged at 8 p.m. on March 11, five hours after the earthquake. The No. 2 reactor’s pressure vessel suffered damage at 10:50 p.m. on March 14, while the No. 3 reactor’s pressure vessel suffered damage at 10:10 p.m. on March 14. NISA data showed the pressure vessels at the Nos. 1 and 2 reactors were damaged earlier than TEPCO’s analysis showed.

On the other hand, the No. 3 reactor’s pressure vessel was found to have been damaged 13 hours later than TEPCO’s data showed.

NISA presumed the vessels failed when there was almost no water in the reactor cores of the Nos. 2 and 3 reactors.

A proper written record of the lies, untruths and technical errors told by World Nuclear Experts from March 2011 to the current would be pretty thick.

And so well might Westinghouse claim that “Fukushima was an error”. No, “Fukushima” as an informational icon merely confirms that World Nuclear cannot be trusted to tell the truth. Even as it claims a monopoly on the truth, it lies and conveys more false fact than fraudulent used car mechanic.

It has been this way since 1945. Nothing has changed in this regard.

In 1945 the US occupation force raided the laboratories of Japanese scientists who had performed radiological surveys of Hiroshima. They confiscated all the written data, all the soil samples, and took human body parts back to the USA.

These things were not returned to Japan until the 1970s.

In the interim both the USA and Japan both maintained that, apart from a declated weenie area of the northern suburbs, no fallout out was deposited in Hiroshima.

This is patent crap. Scientists confirm that cesium and strontium in soil under houses of Hiroshima rebuilt in 1945 has and can continue to be found. It is demonstrably from the 1945 bomb, not from later nuclear emitting events. Such later global fallout form with bombs or Chernobyl. Chernobyl fallout has been identified in Japan.

When you add it all up, you cannot trust the experts to tell the truth or even to fulfill the requirements of the law of any land.

    History paints a great picture of how the Japanese Gov’t and TEPCO LIED to the Japanese People about Fukushima…

    … and Shame on them forever for continuing to do so!
