@Edano The article you recommended states, human workers are unable to tunnel into the ground beneath the reactors to determine location and condition of the cores because of high radioactivity. Why not tunnel underground with robotics installed with cameras. Its done all the time in medicine to explore or perform surgeries.

@MaryW tepco ordered some special cameras from sweden so they may be going to do that

another major flaw in the design of a nuclear power facility is, allowing more than one reactor on a site. The reactors are situated too close to each other. So you risk the domino effect, as we seen with #3 and #4.

When the government investigated whether the extent to which penetration of radioactive cesium in soil within 100 km radius of Tokyo Electric Power Company Fukushima Daiichi nuclear power plant, it was found that did not check the warning area 20 km radius. Criticized by experts and additional research in the area warning this year. May inflate the cost of decontamination depending on the results.

　The survey of about one month from June the Ministry of Education, to assist in decontamination work carried out in cooperation with 94 institutions, such as Osaka and Tokyo. 5 cm of soil stripped away from the surface force of 100 kilometer radius 2200, published a map that contamination by examining the extent to which contains cesium.

　The ministry survey which may have a depth ranging cesium contamination. Determined to take a soil depth of 20 cm or 300 at about 100 km radius, the area is also wary 調Benakatta one place. The analysis of Osaka University, 90% off at the point of a mere warning area within 5 cm from the surface was 7 cm at the deepest.

TEPCO abandons Higishidori NPP plans:
TEPCO 30, decided to abandon the construction of Unit 1 nuclear power plant started construction in January Higashidori Higashidori village in Aomori Prefecture.

　To advance the Fukushima Daiichi nuclear accident compensation, they can not ensure adequate construction funds. Show the attitude of strict construction of new nuclear power stations the government's aborted plans emerged was the first concrete.

　Unit 1 BWR type of improvement (ABWR) and the output 5000 of the nation's largest 138 million kw. TEPCO aims to start construction began operation in March 2017 and suspended by the Fukushima Daiichi nuclear power plant accident, did not reveal the decision to resume or discontinuance. Expected to cancel the construction of Unit 2 nuclear power plant was scheduled to begin operation Higashidori after 20 years.

　Government for the construction of new nuclear plant has plans to allow in principle, Minister Noda in October, "some have willingly substantial construction. We determine in keeping beyond the local to each project's individual" thought and were disclosed.

High levels of cesium found in port soil at Fukushima Daiichi plant

TOKYO, Dec. 1, Kyodo

High levels of radioactive cesium have been detected in seabed soil at the port by the crippled Fukushima Daiichi nuclear power plant in Fukushima Prefecture, the plant operator said Thursday.

Soil samples taken at nine spots at the plant port in late November contained as many as 870,000 becquerels of cesium-137 per kilogram of soil and 730,000 becquerels of cesium-134 per kilogram of soil, according to Tokyo Electric Power Co.

The highest concentration of radioactive cesium was seen in an area just south of the water intakes for the Nos. 1 to 4 reactors at the plant.

The utility attributed the deposits to the leak of highly radioactive water into the sea in April following the nuclear disaster at the plant in the aftermath of the March earthquake and tsunami.

''The pollution will not spread because we have stopped leaks outside the port with plates made of lined steel pipes,'' Junichi Matsumoto, a TEPCO spokesperson, said.

Gov't sets radiation limit for school meals in 17 prefectures

TOKYO, Dec. 1, Kyodo

The Japanese government has instructed the education boards of 17 prefectures in eastern and northeastern Japan to set the upper limit on radioactive substance exposure for food and drink served in school meals at 40 becquerels per kilogram, officials said Thursday.

The directive on meals offered at elementary and junior high schools is the first issued by the central government since the Fukushima nuclear crisis was triggered by the March 11 earthquake and tsunami.

The threshold is one-fifth of the current provisional limit on radioactive cesium for items of general consumption -- 200 becquerels per kilogram for drinking water, milk and dairy products.

The maximum allowable amount for rice, vegetables, meat and fish is set at 500 becquerels per kilogram.

The officials of the Ministry of Education, Culture, Sports, Science and Technology said they newly set the criteria for school meals as the government plans to lower the upper limit of annual internal exposure to radioactive cesium through food and drink consumption to 1 millisievert from the current provisional threshold of 5 millisieverts.

The 17 prefectures include Fukushima, Iwate, Miyagi, Ibaraki, Tokyo, Niigata, Yamanashi, Nagano and Shizuoka.

The ministry has earmarked about 100 million yen in the third extra budget for the current fiscal year to cover part of the cost to purchase dosimeters to detect radiation amounts in meals at schools in the 17 prefectures, according to the officials.

Under the directive, municipal governments are requested to buy equipment that can detect radiation levels in food and drink below 40 becquerels and to stop serving items with radioactive substances that exceed the upper limit, the officials said.

now this is really criminal: noda advised tepco to make a false statement about the location of the corium, only that he can announce cold shutdown the next day. now the lifting of the evacuation zones will be done. this is mafia government. pfui teufel.

by Edano via Polpix.sueddeutsche 12/1/2011 11:22:20 AM

tepco and govj had a problem: with unknown status of corium, they could have never been able to announce a "cold shutdown", which is a prerequirement for lifting the evacuation zones. so they made an agreement and decided to invent a fantastic story about corium having eroded a tiny little bit into the concrete containment, but not over the steel barrier, and now it is stable. so by admitting a little bit damage to conctrete without fully breaking the containment they think they can cover up the entire truth and people will swallow it. problem solved. this is what i make of that story. they bought a bunch of "experts" and added some ridiculous details like "65cm" to make it sound realistic. how can they determine the depth without seeing it ? they are liars.

Fukushima seeks govt aid for rice inspections

Fukushima Prefecture has asked for government assistance to carry out emergency checks of rice for radioactive materials.

The prefecture's Vice Governor Yusaku Matsumoto visited Senior Agriculture Vice-Minister Nobutaka Tsutsui on Thursday to ask for the help.

Fukushima decided to check crops of 24,000, or more than one third, of its rice farmers a few days after rice recently harvested in the prefecture was found to be contaminated by radioactive cesium above the state limit.

The prefecture asked the government to lease devices to measure radiation, dispatch personnel to expedite inspections, and shoulder the cost of the checks.

Tsutsui said the government will do all it can to offer necessary support.

#Fukushima I Nuke Plant Reactor 1: TEPCO and NHK's Obfuscation on Corium in the Concrete : It has been discovered by TEPCO's analysis that the significant amount of Reactor 1's melted fuel pierced through the steel Reactor Pressure Vessel and dropped onto the Containment Vessel, then melted the concrete at the bottom of the CV. It is estimated that the melted fuel may have eaten into the concrete to maximum 65 centimeters deep.

Maximum 65 centimeters deep from the bottom of the concrete floor, right?

Well no. It's 65 centimeters from the bottom of the deep groove on the concrete floor.

And neither NHK nor TEPCO would bother to tell you how deep the groove is. ex-skf.blogspot.com

@Majj it is obviously a lie, pure fantasy.
by Edano 12/1/2011 11:47:33 AM

I grabbed a picture last night of unit 5's pedestal area and did some zoom in shots. I don't know if unit 1 has the same "pits" or grooves in the floor but it does have a sump on one side showing in the elevation drawing. I can get a measurement of the sump from unit 1's drawing. The picture of 5 shows pit on at least 1 side. There might be pit on the other side but the photo doesn't clearly show.
I can repost those pics if anyone wants them up again
by lillymunster 12/1/2011 12:23:45 PM

@Edano they claimed they used a Westinghouse reactor modeling program to come to this conclusion. Even with that they can't fully know because they don't know what pipes inside were broken especially in unit 1 where we know there were pipe breaks. They admit the entire core of unit 1 was ejected. Is there a way to get the total volume of melted material or at least a close estimate? We could use that to get some sort of ballpark estimate about the pit filling up and corium flowing laterally. If unit 1 only has the one sump pit I don't think it would be enough to prevent lateral corium flow.

As I read the bits of info that came out over the day and evening yesterday it seems like this is TEPCO's warm up for an admission at the end of December. Either their cold shutdown fantasy by claiming corium is inside "containment" still or to warm people up for worse news when they get cameras and start drilling.

I am confident they have corium outside containment in at least some of these situations due to the massive steam and radiation outside the buildings and outside containment.

@lillymunster i've made that calculation here, but i don't remember when.
by Edano 12/1/2011 12:28:30 PM

@lillymunster It is possible to calculate, with extreme precision, the volume of molten core in each reactor. It's simple geometry.
