Having ignored the increasing heat indicated, Tepco cancelled measuring radiation level of reactor2
Posted by Mochizuki on January 8th, 2013 · No Comments
Having 2 thermometers indicate rapidly increasing temperature, Tepco labelled them as “broken” for unidentified reason. [Link]
However, on 1/8/2013, Tepco cancelled the measurement of radiation level in reactor2 according to their press release.

Tepco plans to discharge contaminated water into the environment, “Getting permission of related departments”
Posted by Mochizuki on January 6th, 2013 · No Comments
In the first press conference of Tepco on 1/4/2013, Tepco implied they are to discharge contaminated water to the environment.
In this conference, Tepco commented they can finally start talking about the permission from the departments in charge once they manage to change the contaminated water into clean contaminated water by operating the multiple nuclide purifying system “ALPS”.
In this conference, Tepco commented they can finally start talking about the permission from the departments in charge once they manage to change the contaminated water into clean contaminated water by operating the multiple nuclide purifying system “ALPS”.
This facility called ALPS is supposed to be the ultimate water purifying facility but they have been failing in getting it in operation [Link 1], and it was not known why it was supposed to solve the contaminated water problem.
(ALPS ; A new water purifying facility of Toshiba, which is supposed to filter 62 sorts of nuclides including strontium.
They expected to start the facility by this September, but because of the orders and reorganization of NISA and NRA, they can not start Alps yet. It’s not even known when they can start it.)
Tepco’s comment made it clear that the operation of ALPS justifies Tepco to discharge the contaminated water into the environment.
At this moment, the contaminated water tank is 96% full. Tepco decided to stock the contaminated water in 2 of the 4 holes dug in the ground covered with leakage isolation sheet, which were to stock the clean contaminated water purified by ALPS if it was in operation. (*1)
One of the independent administrative corporations in Yokohama, National Research Institute of Fisheries Science,Fisheries Research Agency started analyzing otolith 30 fish caught from offshore Miyagi and Fukushima after August, 2012 so that they can identify if the fish took radioactive material just after 311 or they are constantly taking it from the mud of sea ground etc. (*2)
However, if Tepco discharges contaminated water again, it is anticipated that the sea contamination would be even worse than now.

[Express] “Tepco, the thermometer of reactor2 was disordered”
Posted by Mochizuki on January 4th, 2013 · 1 Comment
Introducing important tweets as [Express] for simultaneous updates.
Two of the thermometers of RPV in reactor2 are showing the rapid increase of temperature. As to this issue, Tepco asserted it’s the disorder of thermometer again. [Link]
<Translate>
Idogawa town mayor of Futaba machi had the town staff inquire Tepco about the increase of temperature on 1/4/2013. Tepco commented they don’t use the issued thermometer of the bottom of RPV for observation. Probably it’s the symptom before getting disordered. ・・・
It was only Idogawa town mayor of Futaba machi to have asked Tepco about it.
<End>
Having said that, Tepco stated the issued thermometers are used for observation, the dependability is “middle” in their own report published this September. [Link]
In Tepco’s first press conference of 2013, none of the press asked about the issue. [Link]
<Translate>
About the increase of temperature in reactor2, disaster management division of the government commented, “We are not in charge of Fukushima accident. We don’t even have a reason to inquire Tepco.

[Column] What is happening in reactor2 and what can be caused ?
Posted by Mochizuki on January 3rd, 2013 · 1 Comment
A thermometer of RPV in reactor2 keeps indicating the increasing temperature.
Tepco used assert the thermometer was disordered every time they saw it indicate increasing temperature.
However this time, another thermometer located on the top of RPV is showing rapidly increasing temperature too. [Link]
What is going on and why ?
Tepco used assert the thermometer was disordered every time they saw it indicate increasing temperature.
However this time, another thermometer located on the top of RPV is showing rapidly increasing temperature too. [Link]
What is going on and why ?
1. Tepco has been decreasing the volume of water to inject
In the beginning of September, Tepco started having the problem with controlling the volume of injecting water and it still hasn’t been fixed. [Link 1 2]
↓ The chart of the water volume to inject.
As a result, the reactor water level has been decreasing since this September.
↓ The chart of the reactor water level.
2. Possibility of the reaction of fractured fuel
You can not tell how much Xe-135 is being produced in reactor2. [Link] Also, other thermometers are not showing the spike of temperature, so it doesn’t look like the entire reactor is having recriticality.
However, Fukushima Diary is suggesting the hypothesis that pieces of fractured fuel are in individual stages scattered around PCV. (cf, [Column] 3 facts to support the hypothesis that fractured nuclear fuel is in individual stages of nuclear reaction [Link])
There is a possibility that one of the small pieces of fractured fuel started the fission reaction due to the lack of coolant water near the issued thermometer or it shifted to near the thermometer.
(cf, [Disorder ?] Radiation level spiked up to 35.23 Sv/h in suppression chamber of reactor2 as the indicated heat went up [Link])

3. Tepco cannot increase the volume of water to inject due to the lack of contaminated water storage
However, Tepco is facing the serious problem of the plant, which is the shortage of contaminated water storage. A part of the injected water comes to the tank. Increasing the volume of water to inject means further increase of contaminated water.
According to the tweets of actual Fukushima worker Happy11311, the contaminated water storage is being the urgent problem. Tepco built a new water purifying facility of Toshiba called Alps, which is supposed to filter 62 sorts of nuclides including strontium.
They expected to start the facility by this September, but because of the orders and reorganization of NISA and NRA, they can not start Alps yet. It’s not even known when they can start it.
They also expected to reduce the storage capacity because of the new water purifying facility, so they did not prepared new tanks in case they can’t start Alps.
Now a few hundreds of tones of groundwater flows into the building on the daily basis but they still can’t even finish the bypass construction nor impervious wall. [Link]

4. What would Tepco do ?
Tepco is having the holiday at the moment. They will have the first press conference on 1/4/2013.
They may be asked about the issued thermometer. From their past behavior, Tepco is likely to take down the parameters of the thermometers so we can not keep track of by asserting the thermometers are disordered whether it’s true or not.

5. The best consequence and the worst consequence
If it’s simply and coincidentally that two thermometers got disordered at once, that would be the best consequence. However, if not, Tepco would need to inject further coolant water to potentially lead to the discharge of contaminated water into the sea.

Fukushima Diary reported the unidentified increase of temperature in Reactor2 on 12/30/2012. (cf, [Disorder ?] A thermometer of reactor2 RPV indicating the rapid increase of heat, it reached 152.1℃ on 12/30/2012 [Link])
In this reactor2, another thermometer is indicating the increase of temperature. It’s located on the top of RPV.
According to Tepco, the dependability as “Middle”, which can be used for observation.

[Disorder?] Radiation level of PCV spikes when reactor water level decreases in reactor1
Posted by Mochizuki on January 1st, 2013 · 1 Comment
According to Tepco’s plant parameter, the radiation level of D/W in reactor1 spikes upwhen the water level in reactor decreases, which has been in the decreasing trend since late August.
Only Japanese data of Tepco notes the radiation meter is out of order.
The radiation level is indicated in Sv/h.

[Column] 5 most meaningful events of 2012 related to Fukushima accident
Posted by Mochizuki on December 31st, 2012 · 7 Comments
1. M7 hit Japan on 1/1/2012
At 14:34 1/1/2012 (JST), M7 hit Japan. [Link] It was scale 3 ~4 in Fukushima. 3 hours later, Tepco confirmed the water level of the skimmer surge tank of SFP4 decreased 5 times faster than before. [Link]
Also, the fall-out amount from 1/2 9:00 to 1/4 9:00 went over the total of the entire November. 2011. [Link]
Fortunately this time, Tsunami didn’t hit Fukushima plant but the plant is still vulnerable for Tsunami.

(cf, [Column] 4 reasons why we must be worried about reactor4 “other than earthquake” [Link])
2. Finding of Black substance
In February, citizen’s volunteer group and local official found the extremely radioactive material accumulated on the street in Minamisoma. It was called “black substance”.
It was not seen in Chernobyl, which is unique for Fukushima.

As it became Spring, it was mass generated [Link] and started coming down to Tokyo. [Link] Now it’s known to be cyanobacteria, but nobody has measured how much plutonium is accumulated in it. [Link]
It also produces pollen.

(cf, [Column] 3 reasons why I don’t go back to Tokyo [Link])
3. Social movement
People protested against the nuclear policy of Japanese government.[Link]
Setouchi Jakucho, Sakamoto Ryuichi, a lot of big names joined the protests but most of the media such as NHK avoided covering the movement. [Link]
From June to July, it had a peak, 100,000 ~ 200,000 people joined the protest held every Friday. [Link]
Opposing the restart of Ohi nuclear plant on 7/1/2012, protestors gathered from Sapporo to Osaka.
The Ex prime minister Noda had a meeting with the organizer.
However, Japanese government pushed their nuclear policy ignoring all the protests.

4. Nature published the report about mutated butterfly around Fukushima
On 8/9/2012, scientific reports of Nature published the report titled “The biological impacts of the Fukushima nuclear accident on the pale grass blue butterfly” to be the first to acknowledge biological mutation due to Fukushima accident. [Link]
Also, 10% of aphid in Fukushima were found deformed where it’s normally less than 1%. [Link]
Apart from insects, deformed plants and albino creatures have been seen frequently all around in Japan.

5. Tepco was sued by US Navy sailors exposed to radiation
On 12/21/2012, the complaint against Tepco was submitted to U.S. Southern District Court of California. The plaintiffs are 8 sailors of US Navy. They were involved in disaster relief operations on the USS Ronald Reagan nuclear-powered aircraft carrier. [Link] The sailors each sought $10 million in damages, $30 million in punitive damages and a judgment requiring the creation of a $100 million fund to pay for their medical monitoring and treatments.
This is the first case of Tepco being sued out of Japan. Fukushima is the marine version of Chernobyl, the entire area surrounding Pacific ocean can be the victims.
It could be the trigger of series of international lawsuits against Tepco. [Link]
Fukushima Diary was referred to on the complaints. [Link]
