I wonder if the Russian planes circling Japan were investigating the recent reappearance of i-131 suggesting recriticality : www.youtube.com

but they are all in cold shutdown.
by Edano 9/10/2011 1:34:13 AM

I thought 90% in shut down, what ones are left?

Fukushima disaster: it's not over yet . Six months after the multiple meltdowns at the Fukushima Daiichi nuclear plant, the streets have been cleared but the psychological damage remains
......Each day for most of the past six months, there has been a steady drip, drip, drip of worrying news: cesium found in the breast milk of seven mothers; strontium discovered inside the city limits; 45% of children in one survey testing positive for thyroid exposure. There are reports of suicides by desperate farmers and lonely evacuees, contaminated beef smuggled on to the market, and warnings that this autumn's rice crop may have to be abandoned..... www.guardian.co.uk

@Edano, lilly, the radioactivity in the sludge increased from nothing to 2,300 Bq/cubic meter within two weeks. This long time leaves many possibilites. If the sewage had been contaminated right after the test prior to the one with the high result, the amounts of iodine would have been roughly twice as great.

I saw something remarkable in the radionuclide table lilly posted www.meti.go.jp . I would have anticipated that unit 3 with the mox fuel and the big explosion is the front runner for pu releases. Alas, according to the table, unit 2 released most.
by Peter 9/10/2011 2:04:33 AM

@Peter What the heck? The plutonium is higher for a couple of types in #2 but everything else is lower in 2 than 3. Um....
by lillymunster 9/10/2011 2:13:13 AM

plutonium is a decay product from uranium.

Another batch of TEPCO deaths that didn't get much attention. 4 guys fell off scaffolding on a tower at one of their thermal power plants Suspended state in a thermal power plant smokestacks, four people slipped Tokai, Ibaraki
2011.3.12 12:49
　TEPCO's thermal power plant in Tokai-mura, Naka-Hitachi, Ibaraki Prefecture, state and suspended parts of the chimney during the nine, five were rescued by helicopter, four of them died and fell off. Ibaraki police and 12 were clear. Earthquake death toll was 12 people in the province.

　According to police, Mr. Kazunori Kaneshiro four workers (43), Mr. Takaya Motoshige (20), Mr. Takahiro Island Morning (40), Yu Orita (29) = both Hiroshima.

　Nine, an earthquake occurs during installation of the scaffolding at the top of the chimney 220 m high point. Although five people were rescued by helicopters, such as disaster prevention in Ibaraki, four of the remaining suspended by ropes or safety is likely to have fallen to such a fall.

@Edano , still one would expect more release from the mox fuel at the percentage loaded.
by Peter 9/10/2011 2:35:24 AM

@Peter i wouldn't say so, uranium is not detected (in the list), so the isotopes in the fuel/corium do not seem to leave the rods, only the fission products.
by Edano 9/10/2011 2:39:04 AM

Finally! They are going to remove the debris from the top of 3. We will get some answers about what happened to the reactor well!

　TEPCO 10, began working at the top of the building rubble removal in Fukushima Daiichi nuclear power plant No. 3. Unit 3, because of the explosion damaged the outer wall and the ceiling of the building, which add up debris. Removed until around next summer, leading to eject fuel in the building.

　Exposed workers (exposure) to avoid, remove, use a heavy demolition work on a remote-operated. Around the reactor building "U" shaped platform (30 meters high and 8 meters wide, 150 m total length) making, heavy equipment put on it. The total amount of debris that sees approximately 3500 cubic meters. Debris removed to measure the surface dose, and storing sorted by the size of the dose.

　From around mid-September at No. 4 and advance the removal of the rubble of the building. The relatively low doses of the work area space, a large heavy demolition work on the person riding. To retire with a shatterproof material on sprinkler spray heights. To cover floats on the surface of the spent fuel pool at Unit 4, so come down to protect the wreckage in the pool. (N. I)

Ob_Li translated this for us. I saw the Japanese version video on twitter and thought it sounded interesting. Glad she decided to translate this one. Check out the theory on unit 1

The original website : news.tbs.co.jp

Nuclear energy specialists team analyzed Fukushima Daiichi Nuclear
Power Plant data and put together their opinions. It said "Although
tsunami caused the power plants blackout, it wouldn't have caused
severe crisis like meltdown if it had been handled properly."
The massive tsunami attacked Fukushima Daiichi Nuclear Power Plant. #1
reactor completely lost the AC source. In the crisis like that, the
isolation condenser, aka IC, which enables to cool off steam
throughout the coolant inside of the tank and changes it into water,
then put the water back into the reactor had to be utilized.
The specialist team of Professor Narabayashi of Hokkaido University
and nuclear power plant product maker OB of 34 members started
analyzing the publicized data provided by the government and TEPCO on
their own terms and found out about the trouble of #1 reactor IC.
"Tsunami caused control console board shut down and that generated
wrong signal. Because of this incident, the function conked out." "It
took more than 2 hours to realize the consol board shut down and
restart it. During this event the reactor core got damaged and melt
down started."
The specialist team assume that initial mistake caused fatal damage,
as the Fukushima Daiichi Nuclear Power Pland Director Yoshida was
putting together the recovery plan without realizing IC shutdown.

"If only there had been a proper direction to fully utilize the IC
while complete AC course loss, TEPCO might have been able to avoid
reactor core meltdown. That's too bad." Reactor Engineering Professor
Narabayashi of Hokkaido University
The specialist team considers that the wrong crisis management caused
lethal accident of #1, #2 and #3 reactor. "There wouldn't have been
severe accident like meltdown and hydrogen explosion even without AC
source caused by tsunami, if TEPCO had handled the situation
properly."
TEPCO commented on this analysis and stated "No comment on this
hypothesis theory."

Another detail indicating that the U3 explosion was a PCV event is the massive spike in drywell radiation on the day of the explosion. www.houseoffoust.com
by Ian 9/10/2011 3:13:41 AM

As per my last comment ... www.houseoffoust.com
by Ian via Houseoffoust 9/10/2011 3:14:48 AM

@Edano, where can one find the raw data for containment & core radiation for U3? You pointed to this page www.tepco.co.jp for pressures, but I don't find how to climb up the find the csv data for other measures.
by Ian 9/10/2011 3:20:01 AM

@Ian smoke out of reactor well around that time was very black, clearly not steam. Someone said black smoke could indicate burning concrete?
by lillymunster 9/10/2011 3:23:30 AM

@Ian All of those CSVs still load in on my docs.google.com spreadsheet of them. Use the translated headers on the All Latest page to make sense of the rest, they draw their headers in from the original documents, mostly in Japanese.
by RadioGuy 9/10/2011 3:26:04 AM

which shows as gubberish and question marks
by RadioGuy 9/10/2011 3:26:33 AM

@RadioGuy, hay thanks! Why is it gibberish on top? Can't it be decoded?
by Ian 9/10/2011 3:52:50 AM

@lillymunster, at what time?
The only black smoke I'm aware of wrt U3 was Mar 20-23.
by Ian 9/10/2011 3:53:30 AM

Mar 21-23
by Ian 9/10/2011 3:53:49 AM

@Ian Isn't that the same time as the estimated burn out of the RPV?
by lillymunster 9/10/2011 3:57:53 AM

@RadioGuy, actually I don't see gibberish, the data headers look good. Do you have a feed on containment radiation and that goes back to March 11 or as close thereto?
by Ian 9/10/2011 3:59:22 AM

@lillymunster, yeah, I think Mar 21-23 is when a lot of co
rium was burning concrete. And yet radiation levels didn't increase much if at all then. But my point below was that the very high radiation in #3 drywell was at a peak on Mar 14, the day of the explosion. It then fell thereafter. This is consistent with the largest emissions into the PCV at that time, fitting with melt-through at that time and just before the blast and lessening thereafter.
by Ian 9/10/2011 4:04:38 AM

@Ian hmmm. IIRC containment pressure dropped around the 21st also.
by lillymunster 9/10/2011 4:06:25 AM

And the falling of drywell radiation after the explosion is consistent with an improved ability of built-up of radiation to escape via blast-opened holes.
by Ian 9/10/2011 4:06:54 AM

@Ian I so hope we can get some overhead images as they clean off #3.
by lillymunster 9/10/2011 4:08:50 AM

Nite all - I must get some sleep.
by lillymunster 9/10/2011 4:08:58 AM

@lillymunster, drywell pressure was bottoming out around Mar 21 gyldengrisgaard.dk . Yes, I saw that report you posted. Will be interesting to see what's under the fallen crane! G'nite!
by Ian 9/10/2011 4:11:49 AM

@Ian I dropped the translated headers in at the top of the pages, and froze the the headers so it's easier to read.
by RadioGuy 9/10/2011 4:59:21 AM

@Ian That spreadsheet just calls all of the CSVs from the TEPCO site and propagates the spreadsheet with the data.
by RadioGuy 9/10/2011 5:00:36 AM

FYI, the code that does it is =importData("http://www.tepco.co.jp/nu/fukushima-np/f1/images/csv_level_pr_data_1u-j.csv") for instance.

Tree logs and sawdust used to grow mushrooms in Fukushima are exported all over Japan, as well as the mushrooms themselves. Not until mid-August did the farm ministry asked industry associations to stop sale of tree logs and products from Fukushima prefecture. Fukushima logs suspect in mushroom radiation contamination

BY SATOSHI OTANI STAFF WRITER

2011/09/08

FUKUSHIMA -- Food lovers often look forward to autumn and winter, when the savory zing of mushrooms is found in hearty soups and other tasty dishes.

But the fungi might be in short supply this year following the disaster at the Fukushima No. 1 nuclear power plant.

Mushrooms are thought to absorb radioactive substances like sponges absorb water. Bans have been imposed on the shipment of mushrooms from Fukushima Prefecture, one of nation's main mushroom production centers, because of the radiation leakage from the quake-stricken plant.

Tree logs, used as a medium to grow mushrooms, have emerged as possible culprits for radioactive contamination. The farm ministry and the prefectural government are busy trying to come up with response measures. more at: www.asahi.com

DPJ members criticize industry minister for gaffe over nuke disaster

TOKYO, Sept. 10, Kyodo

Members of the ruling Democratic Party of Japan on Saturday criticized industry minister Yoshio Hachiro for calling areas near the crippled Fukushima Daiichi nuclear power plant a ''ghost town'' following his visit Thursday to the region.

''It was inappropriate. Problems will arise from now on,'' former Deputy Chief Cabinet Secretary Tetsuro Fukuyama said on a television program.

Another senior DPJ official told reporters Hachiro should step down from the post of economy, trade and industry minister.
