Fukushima Update: Fukushima Radiation Release Double Previous Estimates



Japanese officials today doubled their previous estimate as to how much radiation has escaped from the plant in recent months. The Japanese government also said that an extension of the exclusion zone around the plant will likely be enlarged. Currently, nearly 90,000 residents have been forced to evacuate in the exclusion zone.
The organization, The Nuclear and Industrial Safety Agency has said that they believe the radiation released has been estimated at about 770 thousand (770000) terabecquerels just during the week after the March 11th quake and tsunami damaged the plant.
Earlier estimates noted the radiation released to be about 370 thousand terabecquerels.

Wait just a second...

The Nuclear and Industrial Safety Agency (NISA) on June 6 revised the level of radioactivity of materials emitted from the crisis hit Fukushima No. 1 Nuclear Power Plant from 370,000 terabecquerels to 850,000 terabecquerels.

(from 10,000,000 curies to 22,972,972.97 curies)

In addition to the revised estimates, agency officials stated that they believe that reactors 1 and 2 melted faster than TEPCO had previously stated.
Concerns about workers at the plant and their work conditions have risen in recent weeks, with multiple incidents of exhaustion, heat exhaustion and dehydration.
Out of concern for workers and the overall welfare and safety of Japan, a band of retirees, many over 70 years old have volunteered to take over work duties at the plant.


Japanese Green Tea Banned
In other news related to the nuclear disaster, the Japanese government has banned the shipment and sale of green tea that has been growing in several prefectures near the Fukushima Daiichi nuclear plant. This was after testing on samples of tea leaves came up high in cesium, a radioactive element released from the plant, and higher than the legally allowed level. Green tea in prefectures banned include Ibaraki, Chiba, Tochigi and Kanagawa.


Radioactive Rubble
Japan’s Environment Ministry has announced plans to allow the incineration of rubble and possible burying of rubble underground, that may be high in radiation. The plans are designed to speed up the removal and disposal of debris associated with the disaster.
Government officials estimate that there will be over 23 million tons of debris that needs to be removed from coastal areas that were decimated by the disaster, in order to facilitate any rebuilding that will take place.
For those of us who have actually been in drywells the floor is concrete. The core temps are perhaps misleading as they are actual inlet and outlet variations, reflective of core temps.

Richard Lahey, who was head of safety research for boiling water reactors at General Electric when the company installed the units at the Japan plant, says the radioactive core in the Unit 2 reactor appears to have melted through the bottom of its containment vessel and on a concrete floor.

“The indications we have, from the reactor to radiation readings and the materials they are seeing, suggest that the core has melted through the bottom of the pressure vessel in unit two, and at least some of it is down on the floor of the drywell,” Lahey told the paper.
Lahey did add there was no danger of a Chernobyl-style catastrophe.

IAEA report 3/21: Unit 2

Coolant within Unit 2 is covering about half of the fuel rods in the reactor, and Japanese authorities believe the core has been damaged. Following an explosion on 15 March, Japanese officials expressed concerns that the reactor's containment may not be fully intact. As of 19 March, 11:30 UTC, officials could no longer confirm seeing white smoke coming from the building. Smoke had been observed emerging from the reactor earlier. White smoke/vapour was observed again from 9:22 UTC on 21 March and diminished to nearly invisible by 22:11 UTC the same day. During the time of smoke emission, an increase in radiation dose rates was reported at 9:30 UTC 21 March. TEPCO then ordered an evacuation of plant personnel, though workers returned as of 00:00 UTC 22 March

Did yall see the story about the 270 older Japanese that are volunteering to work the front line at Fukushima to protect the younger employees from radiation and certain death? Amazing story.

http://www.reuters.com/article/2011/06/06/us-japan-fukushima-retireees-idUSTRE7551BO20110606

(Reuters) - At age 72, Yasuteru Yamada believes he has a few more good years ahead.

But not so many that the retired engineer is worried about the consequences of working on the hazardous front line cleaning up the crippled Fukushima nuclear power plant.

"I will be dead before cancer gets me," said Yamada, who has organized an unlikely band of more than 270 retirees and older workers eager to work for nothing but the sense of service at the site of the world's worst nuclear disaster since Chernobyl.

Yamada, who spent 28 years at Sumitomo Metal Industries, says the Fukushima clean-up job is too sprawling, too complex and too important to be left to Tokyo Electric Power, the Fukushima plant's embattled utility operator.

Instead, he wants to see the Japanese government take over at Fukushima with his group of graying volunteers with expertise in civil engineering and construction stepping in on an unpaid basis, "like the Red Cross."

Japanese government officials were initially cool to the unsolicited proposal. Goshi Hosono, an aide to Prime Minister Naoto Kan, dismissed Yamada's volunteers as a "suicide corps."

But in a late May meeting at Tokyo Electric's headquarters, Hosono seemed more receptive to the suggestion amid mounting concern about the health risks for younger workers already at Fukushima.

Three unidentified workers collapsed at Fukushima from apparent heat stroke over the weekend. Meanwhile, at least two plant workers have exceeded the government's limit for radiation exposure by a wide margin, putting them at a higher risk of cancer and other disease.

"The problem is that the first wave of workers came for the money. And they didn't - they couldn't - object to the conditions," said Yamada, who has been running his project from a tiny office above a beauty shop a short walk from Tokyo Electric's headquarters.

"Because we don't expect a fee we can speak to (Tokyo Electric) as equals," he said, adding that his team would press the utility to uphold the highest safety standards.

Tokyo Electric aims to bring three reactors at Fukushima that experienced a meltdown to a stable shutdown by January. After that, experts see a project of a decade or more to remove the uranium and plutonium fuel and secure the site.

Kazuhiko Ishida, a 63-year-old construction worker in Shiga prefecture, has volunteered to join Yamada's team. As a young worker, he helped build the Fukushima No. 1 reactor's outer shell and says he had "complicated feelings" watching it blown apart by a hydrogen explosion after the March 11 earthquake and tsunami as its reactor melted down.

"I told my wife I wanted to go," he said. "She told me to do what I had to do."

Yamada met on Monday with Trade Minister Banri Kaieda, whose ministry oversees Japan's nuclear safety agency. Kaieda seemed receptive to the proposal of a volunteer corps, he said.

"Depending on the situation, there might be a need for a suicide mission. But that is the last resort," Yamada said. "I myself would volunteer for that, but everyone must make up their own mind."

Could we get that in rads?
 
HHK announced today that TEPCO will finally start cleaning up the cooling water, instead of dumping it hot, radioactively 'hot', and oily into the sea. Once they get set up to do it, that is...
 
It's Official: "Nuclear Fuel Has Melted Through Base of Fukushima Plant" ... “The Findings of the Report, Which has Been Given to the International Atomic Energy Agency ... Described a 'Melt-Through' as Being 'Far Worse than a Core Meltdown' and 'The Worst Possibility In a Nuclear Accident'"

The Telegraph reports today:

The nuclear fuel in three of the reactors at the Fukushima Dai-Ichi nuclear plant has melted through the base of the pressure vessels and is pooling in the outer containment vessels, according to a report by the Japanese government.

The findings of the report, which has been given to the International Atomic Energy Agency, were revealed by the Yomiuri newspaper, which described a "melt-through" as being "far worse than a core meltdown" and "the worst possibility in a nuclear accident."

***

The pressure vessel of the No. 1 reactor is now believed to have suffered damage just five hours after the March 11 earthquake and tsunami, contrary to an estimation released by Tepco, which estimated the failure at 15 hours later.

Melt-downs of the fuel in the No. 2 and No. 3 reactors followed over the following days with the molten fuel collecting at the bottom of the pressure vessels before burning through and into the external steel containment vessels.

***

"The recovery effort at the plant is likely to be more difficult as they will not be able to use their previous plan to contain the fuel," Yoshiaki Oka, a professor of nuclear science at Tokyo's Waseda University told The Daily Telegraph.

"So it may take longer and be more difficult, but it is something they have to do.

Alexander Higgins picks up on other parts of the Telegraph article underplaying the severity of the crisis, noting:

These are very different things. I don't think the Telegraph understands the difference.

^^^^^Very True. The only concern is... the molten pool on the floor... Intense radiation is know to have a severe effect on reinforced concrete deterioration of the rebar over time, etc... Where's our resident NUKE specialist "THESTATE"? He could probably elaborate on this in detail.

Good point but I was thinking today that if they were saying no meltdown when there was, and no breach of the containment when there was, shouldn't one also assume that when they aren't saying anything about the whole mess being busy nuking its way through the foundation that maybe it already has?

At the rate it is being contained it could also be safe to assume that it will continue until so much material has been blasted away at the atomic level that reactor site will assume the shape of a big sink hole that fills with sea water and emits a green glow down in the bottom.


The trouble with the nuclear industry is those that are in charge can't handle the truth.

We obviously have a lot to learn about this kind of disaster. And unfortunately, it looks like we're learning it. If I were in Japan right now, I do believe I'd feel a lot like a guinea pig.

It seems advocates of nuclear power cannot either. It is amazing the comments that I continue to read on MSM sites continuing to spout false propaganda despite the truth has already been released. Makes me wonder are these people just political idiots posting or do they do so out of fear of their income stream being threatened which is derived from the industry.

So where's all this radiation going? This thing has been billowing tons of radioactive material for months now. Where is it going?
 
Got some sushi last saturday from a japanese restaurant. They were selling T-shirts to donate money to japan. They also proudly said that some items on their menu are still imported from japan.

Once I got home, I scanned the entire order with a radiation detector sensitive to beta as well as gamma. No issues with anything except the scallops. Every item with scallops in it was pulling .3-.5 rads.
 
HHK says the new system designed to eliminate radiation from the cooling water ain't working. It could soon lead to added radiation releases into the sea.

Japan is surrounded by coolant Ocean/Seas... as for the radionuclides, our resident nuke expert member could elaborate on the dissipation of such radionuclides in the pacific ocean, currents, half life stats, etc.
