Blackout hits Fukushima nuclear plant's Nos. 1, 2 units
[…]
Also Wednesday, TEPCO revealed a plan to leave a door linking the reactor and turbine buildings of the No. 1 unit open to reduce humidity in the reactor buildings later this month and help improve work efficiency within them.
Since radioactive materials within the reactor building could leak to the outside through the opened door, the Nuclear and Industrial Safety Agency, the government’s nuclear safety agency, has instructed the utility to report the expected effects of the move on the environment by June 15.

4000mSv/hr radiation in unit 1 reported last Saturday
Is this to be exposed to environment through the 'opened door'?

@radioguy the real threat of a reactor gone bad is beyond the scary scenarios trotted out about terrorist attacks. It still blows my mind that Indian Point is still in operation so close to NYC being an ancient BWR with a full SFP. Yet a bottle of shampoo over 3 oz is a threat to public safety.

Have to go get some work done. Hope to have the MOX shipment info on the website tonight.

I loved this from the Mainichi inspection article bleow: "It was also pointed out that the government's system for predicting radioactive substance doses, known as SPEEDI, was not effectively used."

I don't know, it depends on what their use was right? When the public knows you have the system, and you release nothing, you're implying all is safe. Lies of omission are the TEPCO strong suit.

I stumbled on this in a search: Interesting concept, just English and French so far, but its aim is to collect disaster stories in different languages on one page. p.diim.jp

@jt your article nisa give tepco a week to tell them how much of the 4000msv radiation is escaping from the open door!!!

@elainekirk That'll be interesting.
by radioguy 6/8/2011 3:11:02 PM

@elainekirk Yes, and there has been no status update on that 4000msv leak since.

@radioguy @jt have you seen the propping up of #4sfp doc
by elainekirk 6/8/2011 3:17:13 PM

@elainekirk no, I haven't
by jt 6/8/2011 3:17:56 PM

@trh someone posted the total MOX import to Japan and where it went, sometime in the last 24 hours. I can't find it but I pop in and out of this site constantly. There was a long discussion about the MOX situation, and someone posted total shipments from France.

First container vessel departure since quake. www3.nhk.or.jp After all the great info Majj gave us on cargo ships and ballast water..this really got my attention.

@elainekirk radiation doesnt leaking... 4Sv is radiation dose per hour but it cant leak, radiation can leak only with particles like water, steam, dust, etc, and then the density of radioactive concentration is measured with bequrel or curies

So some reactor/s are melted at Daini, too?
TEPCO mulls release of decontaminated water
The Tokyo Electric Power Company is studying a plan to decontaminate seawater pooled at the Fukushima Daini nuclear power plant and discharge it into the sea.

TEPCO says about 3,000 cubic meters of radioactive seawater has been stagnant in the basement of the plant's reactor and turbine buildings since being hit by a tsunami following the March 11th earthquake.

The utility says the temperature in all 4 of the plant's reactors has fallen below 100 degrees Celsius, but cites the risk that stagnant seawater will corrode equipment.

TEPCO is considering a plan to decontaminate the water so that it meets national safety standards and then release it into the Pacific Ocean.

The utility says the concentration of radioactive cesium in the water is 30 times the permissible limit, but that it contains no other radioactive materials exceeding the safety limits.
In April, TEPCO drew strong criticism for discharging contaminated water with levels of radioactive iodine-131 about 100 times the limit from the Fukushima Daiichi nuclear plant.

The utility will decide whether to discharge water from the Daini plant after consulting with local municipalities, people in the fishing industry, and the Fisheries Agency.

The Nuclear and Industrial Safety Agency says that a full examination of the plan is necessary even if radioactivity is below the safety limit.

It added that the concerns of local municipalities and people in the fishing industry must be taken into account.

The Fisheries Agency says it cannot now authorize a discharge of seawater even if the level of contamination is under the limit.

The chief of a fishing cooperatives' association in Fukushima Prefecture expressed shock and bewilderment at the utility's plan.

@xxx This is the 4Sv/hr #1 from last Saturday: Steam, high radiation detected at No.1 reactor
The operator of the damaged Fukushima Daiichi nuclear plant says steam was observed coming out of the floor of the No.1 reactor building, and extremely high radiation was detected in the vicinity.  Tokyo Electric Power Company inspected the inside of the No.1 reactor building on Friday with a remote-controlled robot.  TEPCO said it found that steam was rising from a crevice in the floor, and that extremely high radiation of 3,000 to 4,000 millisieverts per hour was measured around the area. The radiation is believed to be the highest detected in the air at the plant.  TEPCO says the steam is likely coming from water at a temperature of 50 degrees Celsius that has accumulated in the basement of the reactor building.  The company sees no major impact from the radiation so far on ongoing work, as it has been detected only within a limited section of the building.  The No.1 reactor is believed to have suffered a meltdown after the March 11th earthquake and tsunami.  It is believed to have created holes in the pressure vessel and damaged the containment vessel, causing highly contaminated water to leak out and accumulate in the basement.  Under the utility's plan to bring the plant under control, a circulatory cooling system is to be installed to decontaminate radioactive water and use it as coolant.

Fukushima Revelations: A health disaster in progress. 4,956 workers contaminated by radioactive particles and only about 10% of workers who were monitored for contamination. translate.google.com
by Bobby1 6/8/2011 3:31:19 PM

@estacion I'm sure the Daini water came from the tsunami, and not groundwater. Tepco always tells the truth... Hmm wait a minute, I thought that the tsunami didn't affect Daini because it was on higher ground.
by Bobby1 6/8/2011 3:38:24 PM

@Bobby1 in your Google translation "TEPCO said that there were only 3 control apparatus for whole body in the Fukushima Daiichi Nuclear Power Station,
but due to high levels of radiation were unable to use these devices." !!!!
by jt 6/8/2011 3:40:54 PM

@jt That is incredibly negligent and criminal.
by Bobby1 6/8/2011 3:43:23 PM

@Bobby1 It sure is.
by jt 6/8/2011 3:44:03 PM

More from that document: "Nobuaki also gave important information: 1193 has been found that workers had higher internal radioactive contamination in excess of 10,000 cpm, corresponds 100 uS / hour 100x24x364 = 873 mSv / per year! - If the value of internal contamination is greater than 6,000 cpm decontamination is considered as "vital." Failing to respect these values in the case of mega Fukusima nuclear disaster, the Japanese government "with the advice of the experts" of the IAEA (International Atomic Energy Agency) simply raised the March 21, 2011 the threshold of internal irradiation 6000 cpm to 100,000 cpm!"
by Bobby1 6/8/2011 3:48:19 PM

But, are any TEPCO report about DAINI reactor melted?
Water on basement have cobalt, too.

What a joke.

Ministry failed to publish some radiation data
The Japanese government says it failed to publish some radiation data from the nuclear accident at the Fukushima Daiichi plant.

The science and technology ministry says it did not release radiation monitoring data from March 16th through April 4th and radiation measurements for soil on March 16th and 17th. The data was taken by the Fukushima prefectural government outside a 20-kilometer radius of the plant.

The ministry apologized for not disclosing the data.
It says it thought the Fukushima government had already released it.
The data was collected as a reference for deciding on evacuation measures and restrictions on food and water consumption. The ministry says the unpublished information does not affect the steps that are now in place.

The ministry says it will publish the data on its website.

back... at my office will be back and forth
by Dean 6/8/2011 4:09:51 PM

@estacion There is no meltdown at Fukushima Daiini, that we know of. Why do you ask? Because of a trace of cobalt in contaminated waters?
by Pedro Jesus 6/8/2011 4:11:39 PM

@dean hi
by elainekirk 6/8/2011 4:12:13 PM

Yes, for cobalt and 30 times limit of cesium in it.
by estacion 6/8/2011 4:13:42 PM

@estacion bit worrying when tepco admit to a hole , goodness fuku was under control until the pesky unit blew up.
mmm they will be struggling to cry tsunami damage for that hole because it looks to be caused by movement as in ....quake?
by elainekirk 6/8/2011 4:17:45 PM

@estacion Where did you get that information from? Not from the article you linked. On that article it says that TEPCO measured the contaminants as being below the legal limit for disposal at sea.
by Pedro Jesus 6/8/2011 4:18:18 PM

@Pedro Jesus, down bit more.
by estacion 6/8/2011 4:21:15 PM

well, i wonder. tepco states that their miracle filters remove 99,99% of the radiation, why don't they just use the filters in Daini and bang the cesium is gone. cleaner than the seawater itself.
by Edano 6/8/2011 4:23:03 PM

@Pedro Jesus. Down a bit more in this page.
@Edano. But they would not have any cesium in it.
by estacion 6/8/2011 4:25:25 PM

@Edano It's not TEPCO. It's AREVA, the French company who is providing them, who claims that.
by Pedro Jesus 6/8/2011 4:25:45 PM

@Pedro Jesus all the same mafia liars.
by Edano 6/8/2011 4:29:35 PM

@Edano Yup.
by Pedro Jesus 6/8/2011 4:30:52 PM

The million dollar question is why they have cesium in basement waters at DAINI if no melt have ocurred?

*melts
by estacion 6/8/2011 4:34:27 PM

@estacion okay, they had a LOCA event (loss of cooling) and they injected seawater and they prepared venting, so i guess they had fuel cladding molten. maybe a beginning meltdown.
