Tepco “Suppression chamber of reactor2 is
more deteriorated than expected”
Posted by Mochizuki on October 10th, 2013 · No Comments
Still it’s not known what happened in reactor2 when 311 took place.
On 9/20 and 9/24/2013, Tepco attempted investigating the water level inside of suppression chamber by using the ultrasonic waves but they failed because the surface of suppression chamber was deteriorated worse than expected.
It is not even clear if reactor2 experienced any kind of an explosion. By investigating the water level inside of the part of reactor called suppression chamber, they could know if it has a hole or not.
The attempt was to run a remote controlling robot around suppression chamber. The robot was to detect the water level by using ultrasonic waves. It was developed by the Agency of Natural Resources and Energy. However, the robot couldn’t detect the reflected wave.
2 years and 7 months have passed but it can’t be known what actually happened in reactor2 yet.
Nearly half of 350 contaminated water tanks
can’t even last for 5 years
Posted by Mochizuki on October 10th, 2013 · No Comments
According to the report that Tepco submitted to Nuclear Regulation Authority, about half of the flange type tanks can’t last for 5 years.
Flange type tanks are easy to build. In order to catch up with the rapidly increasing contaminated water, Tepco is building this type of tanks instead of the welded tanks. However, these are more vulnerable to leak. Currently there are 350 flange type tanks in Fukushima nuclear plant area.
Normally flange type tanks last for 5 years. However, because some of them were provisionally built, they last shorter than 5 years.
In the map below, red represents the tanks that can last for 5 years. Blue represents the tanks that can’t last for 5 years.
Cesium-134/137 density jumped up 13 times much as one day before in Fukushima plant port
Posted by Mochizuki on October 10th, 2013 · No Comments
On 10/9/2013, Cs-134/137 density in seawater increased to be 13 times much as one day before in Fukushima plant port.
The sampling location is in front of reactor2 water intake. Cs-134/137 level jumped up both of inside and outside of the sea fence called “silt fence”.
Inside of the fence, it increased from 90,000 Bq/m3 to 1,200,000 Bq/m3 (Cs-134/137).
Outside of the fence, it increased from 106,000 Bq/m3 to 227,000 Bq/m3.
Tepco announced they assume it is due to the impervious wall construction in the coastal area of the plant, but they don’t plan to stop it.
[Column] ALPS and frozen water wall can be
the performance before discharging
contaminated water to the Pacific
Posted by Mochizuki on October 10th, 2013 · 6 Comments
A person inside of Japanese government said, “Everyone knows Japanese government will end up discharging the contaminated water to the sea.”
Said, “It’s just obvious. There’s no even meaning to put it into words.”
The press reported that an elite bureaucrat said the contaminated water must inevitably be discharged to the Pacific.
This was the reaction of the person to read the article.
According to the decommissioning plan of Tepco and the government, there is no backup plan in case the multiple nuclide removing system and the frozen water wall don’t work. They place them as the last hope.
However, the multiple nuclide removing system stopped only 22 hours after the restart of the test operation.
Also, they have been trying to “freeze” the water since 8/22/2013 but it doesn’t even reach 0℃. Nothing works.
In reality, all those “efforts” can be considered to be a “performance” to look like they are trying to do something.
The bureaucrats know how it will end up in common. Engineers must share the same view.
It’s not only the discharge of the retained water. The contaminated water keeps increasing by hundreds of tonnes everyday. Giving it up means they will keep discharging it for 40 years or 60 years until they finally decommission the plant (if they manage to invent some miracle technology someday somehow.).
This would destroy the Pacific. Not to mention, the fishery industry along the Pacific and all the industry related to the sea can be damaged. The only theory to deny this possibility is “but the sea is big, maybe big enough”, that’s it.
To “justify” themselves to discharge the contaminated water, they need to be able to say “we did our best, but we can’t help discharging it”. So to speak, it’s an excuse.
I don’t know how to vanish the contaminated water from the earth myself. We need to be prepared for the worst.
Tepco doesn’t analyze retained water in the
tank areas before tropical cyclone dilutes it
Posted by Mochizuki on October 9th, 2013 · No Comments
Typhoon DANAS has become a tropical cyclone but they forecast it will cause the heavy rain in Fukushima plant area from this Friday to Saturday.
Since mid September, Tepco has been having to discharge the water retained in the tank area dams to the plant area, where is directly connected to the Pacific.
They claim the contamination level of the discharged water was the same as rainwater. However, having the next rain come shortly, they announced they will not analyze the retained water in the dams before it is mixed with rainwater.
If they analyze high level of contamination before the next rain, it proves they are expecting the rainwater to dilute it so they can discharge, but because they don’t analyze it, we cannot know if it’s purely the natural rainwater.
10 million Bq of Cesium-134/137 are still
released from reactor1 ~ 3 every single hour
Posted by Mochizuki on October 8th, 2013 · 1 Comment
Although it’s been 2 years and a half, 10 million Bq of Cs-134/137 are still released from reactor1~3 every single hour this September, according to Tepco.
This is based on the dust sampling analysis of each reactor.
The releasing volume of reactor1 hasn’t been decreased since September of 2012. In reactor3, it hasn’t been decreased since November of 2012.

Tepco has been dismantling the tank since yesterday that experienced the 300m3 of leakage. The structural flaw may cause other tanks of the same type to leak commonly. Tepco is investigating the potential leaking points.
From their inspection, they found 2 holes around the bolt parts, which are 3mm × 11mm and 3mm × 22mm.
The flange parts were rusting inside and outside. The bottom parts of the tank were found severely deteriorated.
230,000,000 Bq/m3 of Tritium detected near
300m3 leakage tank / Something still leaking ?
Posted by Mochizuki on October 8th, 2013 · No Comments
Near the tank area that experienced 300m3 of leakage, radioactive water Tritium density is increasing in the groundwater.
The leakage is supposed to have stopped already. Tepco hasn’t made any explanation about this increase.
Tritium density in one of the borings reached 230,000,000 Bq/m3 on 10/8/2013, this is the highest reading since they started the measurement in this area.
It’s nearly 4 times higher than even the safety limit (60,000,000 Bq/m3).

Tepco released the photos of the broken parts of the damaged stack on 10/7/2013. The image quality is low for some reason, but we can clearly see the parts completely cut off.
According to Tepco, the stack has 5 parts broken, and they are all concentrated at 66m height from the ground. The reason is not verified.

Tepco mis-operated to stop coolant system of
Reactor1 and gas management systems
Posted by Mochizuki on October 7th, 2013 · 2 Comments
On 10/7/2013, the coolant water pump of reactor1 and gas management system for reactor1 and 2 were stopped by Tepco’s mis-operation.
In the power facilities patrol, an inspector turned off a common power panel mistakenly.
The back-up systems were turned on according to Tepco. About 3 hours later the power panel was restored but the coolant water pump and gas management systems are still relying on the back-up system.
Tepco states there was no specific manual about the patrol, and the inspectors were not trained enough to operate the facilities that were not ordinarily used in a nuclear power plant.

Cesium Found In Children’s Urine Shows Ongoing Widespread Problem In Japan
The acceptable amount of radioactive cesium in human urine is zero. The substances (cesium 134 and 137) does not exist in nature and cause damage to the human body. It was widely reported that a citizen group in the Tokyo region found cesium in children’s urine recently. While this is notable, it isn’t unique. Radioactive cesium has been found in the urine of children across a wide area of northern Japan since 2011. The levels do … Read entire article »
NRA Demands TEPCO Fix Problems, Send Staff From Other Plants To Fukushima
The NRA had nothing good to say to TEPCO president Hirose today. In a rather scathing rebuke of the company, Katsuhiko Ikeda of the NRA blamed TEPCO for making “rudimentary mistakes” and said management is deteriorating. The NRA told Hirose to submit a report within a week explaining how they will fix the situation. They told Hirose to bring staff from other … Read entire article »
TEPCO Gives $2 Million To Pro Nuclear Village While Evacuees Wait For Compensation
TEPCO payed out their portion of a $2 million payment to the village that sits near their planned new nuclear plant in Aomori prefecture. TEPCO had promised to cease such payments as part of their government restructuring. The Higashidori proposed nuclear plant is unlikely to be completed after the NRA raised concerns about an active fault running under the reactor site. … Read entire article »
TEPCO Has Excess Winter Capacity, Restarts Serve Only Business Interests
In this report to METI TEPCO admits that with all of their nuclear plants offline they have excess power generation capacity for the winter. This admission shows that the restart of Kashiwazaki Kariwa would be solely for TEPCO’s benefit and not due to any actual power demand in the region. This makes the push to restart Kashiwazaki Kariwa purely a political … Read entire article »
