#Fukushima I Nuke Plant: Reactor 2 Double Door Will Be Opened on June 19 Night, JST

The double door will be opened from 8PM on June 19 till 4AM on June 20, JST, according to TEPCO's press release on June 19 (in Japanese).

TEPCO has been running the air filtering system in the Reactor 2 reactor building in order to lower the radioactive materials in the air inside the building since June 11. The company is hoping to reduce the amount of radiation to one-tenths before they open the double door to the reactor building.

The Reactor 2 reactor building shell is relatively intact, causing the very high humidity and temperature, hindering any work by carbon-based workers inside. By opening the double door, they hope to drive out the moisture and humidity enough so that they can send in the workers.

Well, the amount of radiation doesn't seem to have dropped at all, as you can see in the chart below (by TEPCO, as a handout at the press conference on June 19), but they are going to open the double door anyway. It was the same story for the Reactor 1; the air filtering system didn't lower the radioactive materials in the air, but they opened the double door anyway, claiming the level got lower.


All for the show, except it exposed the workers to unnecessary radiation when they were sent in to install the air filtering system.

If TEPCO knows it is a futile effort to install air filtering system before opening the double door, why does the company do it? It's for the public consumption, to show that TEPCO is doing everything they can to ensure the lower radiation level for the workers and for the community (which has all but evaporated). And to keep the regulatory agency, NISA, happy.

And why do they open the double door at night? As I said when they opened the double door to the Reactor 1 reactor building, this one is for the maximum effect of letting the inside "hot" air out as much as possible, using the air temperature difference between inside and outside. The relatively intact building shell may hinder the air exchange though. We'll see.

I'll look forward to seeing the gamma-ray photos of the reactor.

#Radioactive Tea in France: Shizuoka Governor Tells France Tea Is Safe, "No Problem"

Besides, the tea leaves may not be from Shizuoka anyway, says his government.

The Oxford PhD (in comparative economic history) governor of Shizuoka strikes again, responding to the news that the French authorities confiscated the radioactive tea from Shizuoka Prefecture at the Charles De Gaulle Airport in Paris for the high radioactive cesium count (1038 becquerels per kilogram), more than twice the safety limit for the EU. (I'm rather surprised that it's that high in the EU.)

From Asahi Shinbun (10:43PM JST 6/18/2011):

「静岡」の茶から基準を超える放射性物質が検出されたとのフランス政府の発表を受け、静岡県の川勝平太知事はコメントを発表し、「仮に製茶の数値が 1千ベクレルだとしても飲用茶にすれば10ベクレル程度になる。飲んでもまったく問題ないと考える」と県の独自調査の結果を示して安全性を強調。その上で 「情報を確認し、早急に輸出ルートを調査する」とした。

Governor Heita Kawakatsu of Shizuoka Prefecture issued a comment in response to the French government's announcement that the radioactive materials have been detected in Shizuoka tea in excess of the safety limit, and said "Even if the final blend tea measured 1,000 becquerels/kilogram, when you brew it the number will go down to about 10 becquerels. I don't think there's any problem at all if you drink the tea." He emphasized the safety of Shizuoka tea showing the survey done by the prefecture. He added that his government "will verify the French information, and investigate the export route."

 茶の輸出手続きを担当する同県経済産業部によると、フランスで検査対象となった茶の最終加工地が「静岡」だった可能性はあるものの、県内では他県産や海外産の茶葉を加工して出荷する場合もあり、茶葉自体がどこで生産されたものかはまだ分からないという。

The Economy and Industry Division of the Shizuoka prefectural government, who is in charge of export control of the teas from Shizuoka, said it was possible that the tea tested in France was final-blended in Shizuoka, but that didn't mean the tea leaves themselves were grown and harvested in Shizuoka. The division said the tea leaves from other prefectures and even from overseas are processed in Shizuoka and then shipped.

I don't have a PhD so I defer to the expert judgment of the governor, who must know more than we the mere non-PhD mortals do.

#Fukushima I Nuke Plant: Kurion's System Was Stopped At the Very First "Skid"

According to TEPCO's handout for the press for June 18, TEPCO stopped the entire water processing system manually when the surface radiation at the "skid" for removing oil and technetium exceeded 4 millisievert/hour, the limit set for replacing the zeolite cylinders (which TEPCO calls "vessel") inside the skid.

That "skid" contains 4 cylinders filled with SMZ (surfactant modified zeolite) to absorb oil and technetium. (The system diagram by TEPCO is provided below, with English labels added by me.)

The cause for the high radiation at the oil-technetium skid wasn't given in the handout, but in the press conference TEPCO listed the following as potential cause:

  • The radiation measurement device picked up the radiation from the pipe that transports highly contaminated water to the system; or

  • The water contained extremely radioactive sludge; or

  • The water contained too much seawater for the system to handle.

By the way, the skids were welded and fabricated by a company in Delta County, Colorado, called Industrial Systems, Inc.. According to the Delta County Independent's article on June 18, 2011, ISI has tripled the number of workers - welders, fabricators, machinists - to 75 to work 24/7 on the project, which for them now includes internal components for filter assemblies in addition to the skids.

#Fukushima I Nuke Plant: Contaminated Water Treatment System May Not Re-Start for Another Week, as Trench Water Rises

More on the news that TEPCO halted the system due to higher than expected radiation level in the cesium absorption subsystem by Kurion:

The radiation limit of 4 millisieverts/hour was reached in 5 hours, instead of one month as anticipated.

New information from Jiji News Japanese (12:47PM JST 6/18/2011):

  • The radiation level on the cesium absorption towers (cylinders) reached the limit [4 millisievert/hour] in 5 hours.

  • The limit was supposed to be reached in a month.

  • There is a possibility that the contaminated water contained the sludge with extremely high level of radioactive materials.

  • TEPCO hopes to investigate the cause and re-start the operation within a week.

TEPCO had better hurry. The water levels in the trenches leading from the Reactors 2 and 3 are rising again, even as the Ministry of Economy, Trade and Industry (METI) has stopped disclosing the information on water levels.

TEPCO discloses the water levels in the daily press conference handouts, and these are the numbers for the trench water levels measured from the top of the grating of the trench pit:

Reactor 2 trench pit:

6/17: 292 millimeters from the top of the grating
6/16: 337 millimeters
6/15: 321 millimeters
6/14: 304 millimeters
:
6/1: 332 millimeters
5/1: 840 millimeters

Reactor 3 trench pit:

6/17: 159 millimeters
6/16: 178 millimeters
6/15: 165 millimeters
6/14: 155 millimeters
:
6/1: 265 millimeters
5/1: 900 millimeters

The Reactor 2 pit water is about 30 centimeters from the top of the pit, the Reactor 3 pit water about 15 centimeters from the top of the pit.

#Fukushima I Nuke Plant: TEPCO Stopped Water Treatment System

The water treatment system for the highly contaminated water at Fukushima I Nuclear Power Plant has been stopped by TEPCO in the early morning of June 18. The system had been on the full "hot" run since 8PM on June 17.

The full run was halted in less than 6 hours due to high radiation level on the cesium absorption towers by Kurion.

The water treatment system is supposed to treat 1,200 tonnes of highly contaminated water every day, or 50 tonnes per hour.

From Yomiuri Shinbun (12:07PM JST 6/18/2011):

 東京電力は18日、福島第一原子力発電所の高濃度汚染水処理システムを同日午前0時54分に停止させたと発表した。

TEPCO announced on June 18 that it stopped the water treatment system for the highly contaminated water at Fukushima I Nuclear Power Plant at 12:54AM on June 18.

 東電は、装置などの故障ではなく、セシウム吸着装置の放射線量が想定より早く基準値に達したためと説明している。処理システムで浄化した水を原子炉に戻す循環注水冷却の同日中の実施は微妙な状況になった。

The stoppage was not due to system malfunction, TEPCO explained. The company stopped the system when the radiation level of the cesium absorption subsystem [by Kurion] had reached the set limit earlier than expected. TEPCO had planned to start the cooling water circulation system whereby the treated water is injected back into the Reactor Pressure Vessels on June 18, but it is not clear whether it will start as scheduled.

 セシウム吸着装置は集中廃棄物処理施設の中に設置されている。交換式の吸着剤が入った容器が6本1組で4列配置され、線量が毎時4ミリ・シーベル トに達すると吸着剤を交換することになっている。東電によると、システムは17日午後8時に本格稼働したが、遠隔操作中の作業員が、セシウム吸着装置の容 器表面の線量計の値が4・7ミリ・シーベルトになっていることに気づいた。

The cesium absorption subsystem is set up inside the Central Waste Processing Facility. There are 4 rows of 6 cylinders that contain cesium absorption material [zeolite], and when the radiation level reaches 4 millisieverts/hour the cylinders are to be replaced. According to TEPCO, the system started the full run at 8PM on June 17, but the worker who was remote-operating the system noticed that the radiation measurement device on the surface of the cesium absorption cylinders was 4.7 millisieverts/hour.

#Fukushima I Nuke Plant: 2 TEPCO Workers Who Exceeded 600 Millisievert Radiation WERE Wearing Masks, No KI Available Until Too Late

Remember the news on June 3 about 2 TEPCO employees working at Fukushima I Nuclear Power Plant exceeding 600 millisieverts in radiation exposure, with extremely high internal radiation?

At that time, the blame was placed on the workers for not taking the potassium iodide pills as scheduled and not wearing masks - what disregard for safety!

When the management blames workers, the management is hiding something bigger and more serious, I've been told.

No newspaper or TV station pursued the news after June 3, until TEPCO announced the result of its investigation of the incident on June 17.

As I had suspected, it had nothing to do with the workers' errors.

They wore dust masks as instructed, and even those they had to take off to eat food, and there was a gap between the mask and the eyeglasses for one of the workers that cannot be closed due to the design. As to potassium iodide pills, they didn't take them initially because there was none where they were (the central control room for the Reactors 3 and 4), when they mattered most (March 11 and 12 and 13).

They were working, eating, sleeping in the central control room for the Reactors 3 and 4 until 4PM on March 13, with dust masks and no potassium iodide.

Here's some information about the incident from the 25-page report attached to the TEPCO's press release on June 17 (available in Japanese only):

1. The 2 workers worked mostly in the central control room for the Reactors 3 and 4.

2. About masks:

  • On March 12, long before the Reactor 1 building blew off (3:36PM), the radiation level started to go up as indicated by the exhaust pipe monitoring at the central control room, around 5:04AM.

  • The manager in charge of the shift at that time instructed the workers to wear dust masks inside the control room, and charcoal masks when going outside.

  • The 2 workers followed the instruction and were wearing dust masks. Dust masks cannot filter out radioactive iodine, and charcoal filters may have become less effective as they were used for extended period of time until the fresh supply could be delivered.

  • At that time, there were 15 charcoal masks, 50 pairs of charcoal filters, and 300 masks [without filters attached?面体] for the Reactors 3 and 4 workers.

  • One of the workers wore eyeglasses, and that left a gap between the full-face mask and the face. There is no way to seal the gap, according to TEPCO.

    [It is extremely hard for me to believe there is no mask for people wearing eyeglasses.]

  • The 2 workers had to eat and sleep in the central control room until 4:00PM on March 13. While eating emergency food in the central control room, they had to take off the masks. The door to the central control room got warped by the impact of the Reactor 1 bldg explosion, and didn't properly close.

  • When the Reactor 1 building blew up on March 12, there were workers outside working without any mask.

3. About potassium iodide pills:

  • TEPCO had 30,000 pills stored in the building off the Reactor 1 (where the plant headquarters are; many workers still live there) prior to the accident. They were not stocked at the central control rooms.

  • The company instructed on March 13 [AFTER the Reactor 1 building blew up on March 12] that the workers less than 40 years of age take potassium iodide pills. For the workers 40 years of age and above, the pills would be given if they requested.

  • The 2 workers couldn't start on the pills until they moved to the building where they could get potassium iodide until 4:00PM on March 13.

This is borderline criminal, particularly about potassium iodide. From the detailed reports that TEPCO suddenly disclosed in mid May, the company knew from the beginning of the accident (evening of March 11) that the reactors may have been breached; they were measuring a very high air radiation at the plant on March 11, which they correctly attributed to a breached Reactor Pressure Vessel. They also knew the venting of the Reactor 1, which was scheduled on March 12, would release a large amount of radioactive materials in the air. And they waited until March 13 to instruct workers to take potassium iodide?

And the company had a gall to blame its own workers at first. Now that it has turned out that the company was to blame, the incident is due to the unfortunate confusion in the early days of the accident.

#Fukushima I Nuke Plant: Full "Hot" Run Starts at Contaminated Water Treatment System

After changing the "rupture disks" for the Kurion's part of the system and blaming the workers for closing the valve by mistake, TEPCO has started the full run, using "hot" water that they have in abundance (over 110,000 tonnes of it) at Fukushima I Nuclear Power Plant.

It must mean they were really running out of space to store the highly contaminated water, and have decided to run the full system made up of 4 different components by 4 different vendors (Kurion, Areva, Toshiba, Hitachi) with what looks to me like a very short test run. Or is this normal time-frame for a test run of the system like this? I'm no expert so I don't know for sure.

From TEPCO's handout for the press on June 17 (in Japanese only):

  • Kurion's system tested: from 3:45AM to 2PM, June 14 (10 hours and 15 minutes)

  • Areva's system tested: from 1:10PM to 8:35PM, June 15 (7 hours and 25 minutes)

  • Kurion+Areva tested: from 10:40PM, June 15 to 12:20AM, June 16 (1 hour 40 minutes)

  • Entire system tested: from 12:20AM to 7:20PM, June 16 when the system stopped (19 hours)

  • Entire system test resumed: from 1:00PM to ??? (NHK says the full run started in the evening, so 6 hours? making the total system test run of 25 hours)

If the "hot" water ever leaks like the low contamination water did (to the tune of 6 tonnes), I hope TEPCO and the participating companies have a plan ready to fix the leak.

Other potential Murphy moments would include:

  • Heavy rain

  • Seawater (neither Kurion's nor Areva's system has dealt with contaminated seawater)

  • Super "hot" radioactive sludge from the process, estimated to be 2,000 tonnes (no one knows what to do with them)

Even the cesium absorption towers (cylinders) need storage space after the run every day. TEPCO will need to replace one a day.

NHK World (6/17/2011):

A system to decontaminate highly radioactive water has gone into service at the Fukushima Daiichi nuclear plant.

The system is considered key to dealing with the build-up of contaminated water that is hampering work to bring the reactors under control.

Tokyo Electric Power Company, or TEPCO, activated the system on Friday evening after conducting final test-runs.

The utility earlier found water leaking from one of the system's 4 components -- a US-made cesium absorption device -- forcing the test-runs to be called off on Thursday.

TEPCO later determined that a mistakenly closed valve in the pipes had clogged the water, which then damaged a safety valve in one of the absorption units and caused the leak. The broken valve has been replaced.

Highly radioactive water is building up in reactor facilities at a rate of 500 tons per day. TEPCO hopes to cool the reactors by decontaminating the runoff and re-circulating the water.

Stable operations of the decontaminators will now be important, as the system has suffered glitches both before and during the test-runs.

#Fukushima I Nuke Plant: Kurion's System Leak Was Due to High Pressure in One of Cesium Absorption Towers

Accordingly, the safety valve, called the "rupture disk", ruptured as designed to release the pressure and let the water flow out, according to Asahi Shinbun (in Japanese; 12:01PM JST 6/17/2011).

Why did the pressure go up in that particular set of towers (most upstream of the 4 sets)? Because a valve was closed shut downstream. TEPCO hinted it may have been a human error, that a worker closed that downstream valve by mistake.

The total amount of water leaked was more than 6,000 liters [or 6 tonnes].

TEPCO will replace the ruptured "rupture disk" as well as the same disks for the other three sets of towers, and hopes to start the full run by midnight on June 17.

I was told by a former TEPCO nuclear plant engineer that something else is likely involved when the company wants to blame workers for a malfunction or an accident. We'll see if that's the case here.

The contaminated water situation must be getting really bad for TEPCO to hurry on with the full run that will process the highly contaminated water heavily mixed with seawater.

On the side note, Yomiuri Shinbun reports that the CEO of Areva, Anne Lauvergeon, will not be reappointed at the end of June, in the decision made by the office of the President of France, despite the urging by the company's executive board. Areva is 90% owned by the French government, and the CEO is rumored to have had disagreements with President Nicolas Sarkozy. The new CEO is going to be Luc Oursel, current COO of the company in charge of international marketing and projects. Oursel's name was missing in the letter by the company's executive board urging the reappointment of Anne Lauvergeon, as Reuters reports.

#Radiation in Japan: Testing of Vegetables Only 0.1%, Government Discourages "Unauthorized" Health Checks in Affected Areas

Japan must be the least suited country in the world to deal with an emergency situation, because it doesn't recognize it is an emergency.

Thanks to the net, though, people are speaking up even in Japan and spreading information. Here are two such examples, tweets in Japanese from Japan. They could be what their government and its apologists call "baseless rumors", but I doubt it although 'm not giving any guarantee that they aren't.

(Then again, as one of my Twitter followers reminded me, "Radiation is rumor; safety is religion; ignorance is strength.")

First, a tweet from @tatsuofujii 藤井 辰雄. He says he became a farmer in Inawashiro, Fukushima Prefecture three years ago. He evacuated after the Fukushima I Nuke Plant accident, and says as a responsible producer he wouldn't grow and sell vegetables if there is even a slight possibility that his vegetables may harm children and women capable of becoming pregnant.

His June 14 tweet:

日が経つにつれて危機意識が薄れてる。野菜にこだわって生 産してきた福島の農家として警告します。未だに農産物は出荷量に対し99.9%以上未検査。1市町村1圃場だけのサンプル検査です。自治体が出す安全宣言 などは現時点で非常にいい加減な検査手法により出されています。

I sense that people are getting less vigilant as days go by. But I warn you, as a farmer who has taken much pride in growing the best vegetables possible, that more than 99.9% of the agricultural produce shipped are not tested, even today. The test for radioactive materials is done by sampling in one farm plot per city/town/village. The "safety declaration" by municipalities are being issued, based on this flimsy testing.

So that's how Shizuoka Prefecture may have tested their teas: one bag from one factory per one tea growing region. Unfortunately for the governor of Shizuoka, a Tokyo grocer did the independent testing, and he had to order the testing at all 100 factories in that one particular tea growing region.

Here's a tweet by a medical doctor, @KamiMasahiro 上 昌広. His Twitter profile says he is a doctor in internal medicine, and the site he lists on Twitter goes to the Tokyo University Institute of Medical Science, and he is a professor in the Division of Social Communication System.

His June 13 tweet:
 

飯舘村で一緒に健康相談した医師から。何考えているんだろう。 「本日、病院幹部(私もその一人)に文科省と厚労省の連名で通達が書面できました。原発被害を受けた地域への関係学会が認めない健康診断や調査は住民たちの負担を増やすので、許可を得てからやりなさいと」

Message from the doctor I worked with in Iitate-mura [in Fukushima Prefecture], when we gave medical advice to the villagers. I don't know what they [the government ministries] are thinking. "Today, our hospital received a written notice signed by both the Ministry of Education and Science and the Ministry of Health and Welfare. The notice says "The medical checkups and research of the residents in the areas affected by the nuke plant accident are allowed only if the permission to do so is given by the related scientific societies and associations; otherwise it would only increase the burden on the residents.""

#Fukushima I Nuke Plant: Leak Found, Water Treatment System Test Run Halted

TEPCO was running the test of the entire contaminated water treatment system since 12:20AM JST, June 16, but the test has been halted because of the leak found in one of the cesium absorption towers after 19 hours of running the test. The company was planning to run the test with the low contamination water for 30 to 40 hours before the full operation of the system with the high contamination water.

It looks to be part of the Kurion system which uses a series of towers filled with zeolite to absorb radioactive cesium.

Murphy's still alive and well at Fukushima.

From Asahi Shinbun (12:30AM JST 6/17/2011):

東京電力は16日、福島第一原子力発電所にたまり続ける高濃度の放射能汚染水を浄化処理する施設の試運転中に、一部の装置から汚染水が漏れ出したこ とを明らかにした。装置は自動停止した。水が漏れた場所を見つけて修理するのに少なくとも半日はかかりそうだという。17日に予定する浄化施設の本格稼働 が遅れる可能性が高まっている。

TEPCO disclosed on June 16 that there was a leak in one of the subsystems during the test run of the entire water treatment system that will treat high contamination water at Fukushima I Nuclear Power Plant. The system was shut down automatically. According to TEPCO, it may take at least half a day to identify the location of the leak and repair. It is increasingly likely that the full-scale operation of the water treatment system, which is scheduled to start on June 17, will be delayed.

 水漏れがあったのは、施設のうち、放射性セシウムを吸着させる円筒形の装置。午後7時20分に警報が鳴って装置が自動停止した。午後8時ごろ、作業員が 直径90センチ、高さ2・3メートルほどの装置を入れた金属製の箱に30センチほど水がたまっているのを確認したという。さらに箱の外にまで汚染水が漏れ だしていた。

The leak was found in one of the cylindrical equipment to absorb radioactive cesium. The alarm sounded off at 7:20PM JST [on June 16] and the system was shut down automatically. At 8:00PM, the workers went in and visually confirmed the leaked water 30 centimeter deep inside the metal box that houses the cylinder, 90 centimeter in diameter and 2.3 meter in height. The water had spilled outside the box, too.

 原因について東電は「詳しくは調査しないと分からない」としている。

TEPCO said the detailed investigation was needed to figure out what had caused the leak.

#Anti-Nuke Animation "Uncle Genpachi & Tama" Series

The series was made before the Fukushima I Nuke Plant accident, in Japanese. Now the creator has made the entire series (5 videos) in English.

Tama is the name of Uncle Genpachi's cat, who stands up and starts to speak in anger on hearing misinformation about nuclear energy or nuclear power plant. It's quite funny and informative at the same time. Each video is no more than 3 minutes, but to the point.

#Radiation in Japan: Nosebleed, Diarrhea, Lack of Energy in Children in Koriyama City, Fukushima

Once a malicious "baseless rumor" on the net, now it is written up in a regional newspaper with readership in Tokyo and Kanto area.

Tokyo Shinbun (paper edition only, 6/16/2011) reports that many children in Koriyama City in Fukushima Prefecture, 50 kilometers from Fukushima I Nuclear Power Plant, are suffering inexplicable nosebleed, diarrhea, and lack of energy since the nuke plant accident.

(The photo of the page from this blog site, in Japanese.)

Quick translation of the article:

What's happening to children in Koriyama City in Fukushima right now? Nosebleed, diarrhea, lack of energy - "Effect of radiation unknown" says the doctor

Report by Ao Ideta, Tokyo Shinbun, June 16, 2011

On June 12, a non-profit organization called "The Bridge to Chernobyl" (チェルノブイリへのかけはし) held a free clinic in Koriyama City in Fukushima Prefecture, 50 kilometers [west] from Fukushima I Nuclear Power Plant.

Worried about the effect of radiation exposure, 50 families brought their children to see the doctor.

A 39-year-old mother of two told the doctor that her 6-year-old daughter had nosebleed everyday for 3 weeks in April. For 1 week, the daughter bled copiously from both nostrils. The mother said their doctor told her it was just a seasonal allergy from pollen. Her other child, 2-year-old son, had nosebleed from end of April to May.

The pediatrician from The Bridge to Chernobyl, Yurika Hashimoto, told the mother it was hard to determine whether the nosebleed was the result of radiation exposure, but they should have the blood test done for white blood cells. It was important to keep record, the doctor advised.

The family move out temporarily from Koriyama City to Saitama Prefecture after the March 11 earthquake, but came back to Koriyama at the end of March.

The mother said about 10% of pupils at the elementary school have left Koriyama. Each school in Koriyama decides whether to have the pupils drink local milk that the school provide, which tends to concentrate radioactive materials. In her daughter's school, it is up to the parents to decide. But the mother said she let the daughter drink milk with other children because the daughter didn't want to get excluded by other children for not drinking milk with them.

A 40-year-old father of a 4-month-old baby daughter was so worried that he never let the daughter go outside, even though she didn't exhibit any ill effect of radiation so far. He said, "I'm so worried. I don't know how to defend ourselves."

I [the reporter of the story] used the radiation monitoring device over the low bush near the place where this event was being held. It measured 2.33 microsieverts/hour. As I raised the device higher, the radiation level went down to 1 microsievert/hour. The highest air radiation measured in Koriyama City was 8.26 microsieverts/hour on March 15. Since middle of May, it has been about 1.3 microsievert/hour.

If you live one year in a place with 1.3 microsievert/hour radiation, the cumulative radiation will exceed 11 millisieverts. [And that's only the external exposure.]

A 40-year-old mother with a 6-year-old son was angry, and said "Doctors, researchers, they all say different things. I don't understand how the evacuation areas are determined. Take Iitate-mura, for example. They just let the villagers get exposed to high radiation for a month, and when the air radiation level got lower they told them to move out. We can't trust the national government, we can't trust Fukushima prefectural government." Her family just built a new house, and she was not sure how they could survive economically if they moved. If they moved, when would they be able to come back? What about cost of moving, or the psychological effect on her child? She just couldn't decide what to do.


6.11 No-Nukes Demonstration in Japan: Ground-Zero Report by "J" in Tokyo (Guest Post)

My friend's friend's friend "j" attended not just one but two demonstrations in Tokyo (one in Nerima-ku, and the other, bigger one in Shinjuku-ku) and sent her level-headed and frank observation (original in Japanese).

Several interesting bits of information that I've never seen elsewhere in the news:

  • The Social Democratic Party (former Japan Socialist Party) was there big-time, as if to try to hijack the grassroots movement;

  • Lack of anger toward the government agencies and organizations who have promoted nuclear energy;

  • Volunteer organizations collecting donations during the demonstrations in a manner that ordinary Japanese find hard to say no.

The first point is not surprising to me. It is like the neoconservative right claiming to be the leaders of the "tea party" movement in the US. But I've never read about their presence in the demonstration anywhere else.

The second one is not so surprising either. Trust in the government runs deep, not just in Japan but elsewhere. It is more likely that TEPCO has been obliged to do whatever the government has ordered them to do, including not disclosing the information, but the people's anger are being cleverly directed to the big bad greedy capitalist TEPCO.

The last one reminds me of a street musician group in Paris 10 years ago. They were playing wonderful music, but as we listened, a person with a donation box came and stand in front of the audience, stuck the donation box in front of my face and asked for money. I thought that was crass, not befitting the superb music they were playing.

Still, "j" seems to think it was a significant event, just to show to the rest of Japan and the world that there are people in Japan who are anti-nuclear across the different political and social spectrum.

The following is her personal observation on 6.11 No-Nuke demonstrations in Tokyo, Japan:

昨日の新宿、結構な人数が集まって(首都圏として考えると少ないと思うけど)それなりの盛り上がりをみせてました。午前中のゆるい「練馬アクション」でのモヤモヤを帳消しにはできました。

Yesterday [June 11]'s Shinjuku had a sizable crowd (though not that big considering how big Tokyo is) and a decent action, enough to dispel my vague dissatisfaction with the "Nerima Action" demonstration in the morning.

ただね、参加した私の感想としては、なんだかすごーーーく違和感があったの。それは朝の練馬のときからありました。

But things didn't feel quite right for me, and that feeling started from the Nerima demonstration in the morning.

今回の「6.11脱原発100万人アクション」に私が参加しようと思ったのは、民衆主導のデモだということ、“脱原発”を訴えることが趣旨だということ、の2点。

I decided to participate in the "6.11 No-Nukes One Million People Action" event for 2 reasons: One, it was a grassroots movement; and two, it was to appeal for no nuclear energy.

でもさ、のっかってるんですよ「社民党」が。ガッツリのっかってる。

But then, the Japanese Social Democratic Party was right there at the demonstrations, free-riding the grassroots movement.

私は、これまで個々で活動していた市民団体が一体となって、民衆の声として起こしたものだと思っていたので、これにはかなりゲンナリしました。

I thought this was the people's movement, the small individual citizens groups got together and joined forces. I was rather disgusted to see the Social Democrats there.

練馬でも社民党の旗が振られ、新宿でも同じ旗が振られ、あげく宣伝カーまできて、議員がマイクで一発ぶっちゃう始末。

The Party's flags were waved in the Nerima event, same in Shinjuku, then the Party's PR car came and some party Representative started to make a speech.

これだとさ、いち民衆として参加している私からすると、まるで社民党支持者にさせられているような気分になります。政党がかかわるなら最初から表明してほしかった。

For me, participating in the event as an ordinary citizen, it felt like I was forced to become a supporter of the Social Democratic Party. If a political party was going to be involved, I would have liked to know it from the beginning.

そもそも社民党って、民主党政権発足時に連立組んでたよね。民主党の原発推進マニフェストを受け入れていたってことでしょ。それを今になって「社民党はずっと反原発でした」みたいな顔でのっかってこないで欲しい。

The Social Democratic Party became a coalition partner when the Democratic Party of Japan first became the ruling party. That means these Social Democrats accepted the DPJ's manifest of promoting nuclear energy. Now they're trying to hijack the movement saying they have been anti-nuke all along? Give me a break.

これ1つとっても、この先、デモに参加するかどうか考えてしまう。

Makes me wonder whether I should participate in a no-nuke demonstration from now on.

それと、デモにつきもののシュプレヒコールですが、その内容にも一言いいたい。

I'm not happy with the slogans at the demos either.

今回の趣旨は「脱原発」のはず。

The whole point of the demonstration was to appeal for "no nuke".

東電の責任に関するものは今回は違う気がしましたよ。

Not about accusing TEPCO.

「清水出てこーーーい!」「福島原発をさっさと終息させろ!」(それは、現場ではやってますって)とかは、また別のデモなんじゃないの?って。「東電は全ての原発を停止・廃炉にせよ」「東電は情報を全て公開しろ」だったらOK。

"Shimzu [TEPCO's president], come out!!" or "Do something quick about Fukushima I Nuke PLant!" (they ARE doing something at Fukushima I) - that's another demonstration, isn't it? I'm OK with the statements like "TEPCO should stop all nuke plants and decommission them" and "TEPCO should disclose all information."

そもそも、東電の責任を訴えるのであれば、これまでクソの役にも立ってこなかった、原発関連法人の解体も訴えるべきだし、保安院出てこい!原発推進してきたヤツら出て来い!って、同列に言うべき。

If you're going to hold TEPCO responsible, you should also demand the dismantling of the government corporations for nuclear energy which haven't done sh-t [her word], and shout "NISA, come out! Everyone who's promoted nuke plant, come out!"

なにかこう、東電だけにもってこう的な違和感を感じてしまった。もちろん東電に責任があることは事実だけど、「だけじゃない」でしょ、っていうね。

It felt strange to me, holding only TEPCO responsible. Not that TEPCO is not responsible, but they are not alone, are they?

あとはさ、アルタ前広場ってのは良くなかったね。いや、良かったのか? あそこは広場と名がつくものの、実は狭~いので、多少のヒトが集まるとそれ以上のヒトが集まっているように見える「アルタ前広場効果」なるものがありますからねぇ。

And then, the choice of the Alta Plaza [for Shinjuku demonstration] wasn't good. Oh wait, was it good? It's called "plaza" but the place is actually very small. So, even the small number of people could look big. The "Alta Plaza Effect", so to speak.

東京にはコンコルド広場なみの広場が無いからなぁ。私としてはあれくらいが埋まらないと大規模デモとは呼べないけどね。

Tokyo doesn't have a big space like the Concord Plaza [Place de la Concorde, in Paris, France]. To me, a big demonstration is the one that would fill the Concord Plaza.

あとさ、募金回収が行われているのもちょっとした違和感。

Also, donation solicitation was pretty awkward.

今回のことは、有志が自発的に起こしたものなのに、横断幕や準備にお金がかかったのでぜひ募金を!と練馬でも新宿でも言われたんだよね。しかもヒトが箱持って回ってくるから、日本人としては断りづらいじゃない?(苦笑)でも、なんかそれってヘン。練馬では身元がハッキリしてたので10円募金(ケチ!)したけどさ、新宿のなんか、誰でどこの所属なのか分からんもん。だからスルーした。

The event, as far as I knew, was voluntary. But people came for money in Nerima and Shinjuku, saying it cost money to prepare for the demonstrations so please donate. They stuck a donation box in front of the participants. As a Japanese, it was difficult to say no, but I didn't like it. In Nerima, I donated 10 yen [12 cents] (I'm cheap) because they were what they said they were. But in Shinjuku, I couldn't tell who they were. So I ignored them.

署名もそうね。皆、自分の氏名と住所という大事な個人情報を記入するのに、どこの団体がやっているものなのか、とかあんまり気にしてない。「雰囲気」とか「ノリ」で署名するのって危ないよ。

Same with signature gathering. No one beside me seemed to care very much who they were signing for and gave away the personal information like name and address. It's not safe to give away your information in the excitement of the event, without much thinking.

...とまあ、日本のデモはまだまだ未熟だな~という感じでした。それでも、日本でも所属・思想は別として「脱原発」と思っている民衆が居るのだ、というアピールにはなったと思います。

Overall, my feeling was that Japanese people are inexperienced when it comes to demonstration. Still, I think it achieved the purpose of appealing [to the rest of Japan and the world] that there are people in Japan who are against nuclear power, regardless of the social status or political leaning.

これからは予め募金や寄付をつのって神宮球場とか横浜球場で、ちゃんと舞台作って、主催者をはっきりさせて入場料(500円でワンドリンク付きとか)とって、フェスみたいな感じで集まるのが良いのではないかと思う。

I think in the future it may be better to organize the event as some kind of a festival in a big venue like baseball stadiums, soliciting donations beforehand to plan for the event, and selling tickets (500 yen for admission and a drink, something like that) for people to participate.

Contaminated Water Treatment at #Fukushima I: Final Test Run of the Entire System Started


TEPCO finished the testing of Areva's decontamination system (no word yet as to how successful it was) and started the test run of the entire system (oil/strontium removal - cesium removal (Kurion) - decontamination (Areva) - desalination) at 12:20AM JST, June 16.

The test is scheduled to run for 30 to 40 hours before the full run starts with the high contamination water sometime on June 17.

I still don't quite get it. Why did TEPCO (or the Japanese government) need both Kurion's and Areva's systems? They both treat the same radioactive materials - strontium and cesium. It looks like a political arrangement to me, as the US couldn't just let France's Areva take the credit for cleaning up the contaminated water at a nuke plant with the wrecked GE reactors.

NHK World English: (6/16/2011):

The operator of the damaged Fukushima nuclear power plant has begun testing a complex system to decontaminate highly radioactive wastewater.

Tokyo Electric Power Company, or TEPCO, began the test run early on Thursday ahead of full-fledged operation on Friday.

More than 110,000 tons of the toxic wastewater has accumulated at the plant after months of using water to cool overheating nuclear fuel. The water is hampering work to bring the facility under control.

TEPCO is struggling to find storage space for the water, which is accumulating at a rate of 500 tons daily.

The treatment system combines 4 devices, including those made by French and US makers.
The French-made device uses a special chemical agent to treat the contaminated water. The US-made device is designed to remove radioactive cesium. Tuesday's testing showed it reduced cesium by one-3,000th.

TEPCO plans to reduce the level of radioactive substances to one-10,000th before moving decontaminated water to temporary tanks.

Technical problems delayed the test by 4 days.

#Fukushima I Nuke Plant Reactor 3: Video of Inside the Reactor Bldg (6/9/2011)

Workers from TEPCO and its affiliate companies entered the Reactor 3 reactor building on June 9 to measure radiation levels. (They also took the gamma ray photos, as you can see in my post.)

TEPCO released the video of the work on June 15, and here it is, courtesy of Mainichi Shinbun. (You can download your own at TEPCO's site, here.) According to the caption of the video, it was shot by a Toshiba employee. For their 30-minute effort, they received between 5.88 to 7.98 millisieverts external radiation, twice of what had been planned.

You get to see the contaminated water in the basement, toward the end.

#Fukushima I Nuke Plant: Test Run of Areva's System Starts

TEPCO started the test run of Areva's decontamination system at Fukushima I Nuclear Power Plant using the "low" contamination water at 1:10PM JST on June 15, according to the information to the press for June 15 (in Japanese only; no foreign reporters attend TEPCO's pressers).

No word or information as to whether the test run has completed yet.

After the successful test run of the Areva system, TEPCO will start the test run of both Kurion and Areva's systems together on June 16. The company hopes to start processing the "high" contamination water right after the successful test run of both systems.

TEPCO is running out of storage space for the high contamination water at the plant. There is only 2,200 tons capacity left for the high contamination water at the plant before the water has nowhere else to go, according to Yomiuri Shinbun (link is in Japanese).

Incidentally, the same information sheet from TEPCO says one worker at the plant was caught smoking a cigarette at the dock. At least he wasn't carrying a bucket of uranium like those at Tokai Nuclear Power Plant in 1999.

What's interesting to me is the measurement of this worker's radiation, which was low. But the internal radiation exposure (0.24 millisievert) is almost twice as much as the external exposure (0.13 millisievert).

Of course it is quite possible (even likely) that the external exposure number is not very trustworthy because of the deliberate under-counting which was almost the norm at any nuclear power plant in Japan for the maintenance work.

#Radioactive Tea: Shizuoka Governor Accuses NHK of Spreading "Baseless Rumor"

Again, in "Newspeak" in post-Fukushima Japan, "baseless rumor" means "radioactivity".

(Other "newspeak" examples: "Safe" means "dangerous and/or radioactive and to be avoided", and "no immediate health concern" means "there's long-term health concern".)

But this Oxford PhD governor of Shizuoka is hilarious. In his mind, the report in the newspaper and TV that some of Shizuoka's teas have been found with radioactive cesium exceeding the national safety limit is an unconscionable lie. He accuses the press for saying all Shizuoka's teas are radioactive, when none of them said anything remotely resembling that.

The governor must be suffering a hysteria episode of a different kind.

From Yomiuri Shinbun (8:58AM JST 6/15/2011):

 製茶から国の暫定規制値を超える放射性セシウムが検出された問題で、静岡県の川勝知事は14日の記者会見で、「報道が風評被害をあおっている」とNHKを名指しで厳しく批判した。

Concerning the detection of radioactive cesium exceeding the national provisional level from the "seicha" (final blend tea) in Shizuoka, Governor Kawakatsu held a press conference on June 14 and harshly criticized NHK for creating the "baseless rumor" [on Shizuoka's tea].

 川勝知事は「風評被害の最たるものは、一部のここにいる人たちです。9日の9時台の全国ニュースは、『静岡県で暫定規制値を上回るものが出た』。なんというふらちなことだ。一局所を全体であるかのごとく報道する、本当に道義的に問われるべきだ」と激しい口調で批判した。

Governor Kawakatsu breathlessly accused the press, "The culprits for the baseless rumor are right here [he means the press]. On June 9, on the 9 o'clock national news [on NHK], they reported 'some tea in Shizuoka exceeded the provisional safety limit for radioactive materials.' What nonsense! They report as if the teas in entire Shizuoka Prefecture are radioactive. It is truly unconscionable."

 さらに、「公器であることをわきまえなさい。1面トップや、NHKを見た人が、見出しと報道で、静岡茶は全部やられたと思っています。一部をもって、全体にした反省をしていただきたい。責任重大ですよ、君たち」と批判を続けた。

He continued, "Be responsible as the public media. People who read the newspaper headlines or watched NHK News now think all Shizuoka teas are radioactive. I demand that you apologize for having exaggerated. You will be held responsible, do you understand?"

 NHK名古屋放送局広報部は、取材に対し、「報道した内容は事実です。知事の発言についてコメントすることはありません」と話した。

NHK's Nagoya Station said "We reported the facts and we stand by our report. We have no comments on the governor's remarks."

Ex-CIA Director James Woosley Is With One of the VCs Backing Kurion

Kurion, whose cesium absorbing zeolite towers are getting ready for the full-scale operation at Fukushima I Nuclear Power Plant, has two VCs (venture capital firms) investing in it: Firelake Capital in Palo Alto, California and Lux Capital in New York.

Searching information on Kurion's vitrification method, I found this article instead.

From Greentech Media (4/26/2011):

James Woolsey, the former CIA director and venture partner with VantagePoint Venture Capital, has joined Lux Capital along with Richard Foster, a McKinsey alum and prolific author.

Woolsey is one of the regular speakers on the greentech circuits -- and one of the more interesting ones. He was one of the first to hammer home the lesson that green technology and national security are intertwined. Woolsey will concentrate on energy and Foster on life sciences.

...Ideally, Woolsey and Foster can help the firm create tighter links between its companies and established industries.

Considering one of the largest target customers of Kurion is the US government, having Woosley won't hurt.

#Fukushima I Nuke Plant: Kurion's System Test Run Result

TEPCO did the test run of Kurion's cesium absorption system on June 14, using the "low" contamination water.

The samples after the test was taken at the end of the cesium absorption process, bypassing the decontamination system by Areva (which will be tested on June 15, also using the low contamination water).

According to the number, the amount of cesium in the water was reduced to about 1/3000.

Kurion's system consists of series of towers filled with zeolite. (Tell me again, what's the expertise of Kurion other than putting zeolite in towers?)

TEPCO's press conference handout on June 14 (English labels added by me):

#Radiation in Japan: Cesium from Milk in Niigata Prefecture

(UPDATE) From TEPCO's Kashiwazaki-Kariwa Nuke Plant website (in Japanese only), I've learned that they test radiations in soil, water, food, etc. once every quarter in the area within 5 kilometers from the plant. The latest measurement data on the website is from 2009.

---------------------------------------------------

It is a minute amount, but at least TEPCO's Matsumoto, who announced the news of the detection, didn't say "there is no effect on health" like its regulatory agency in the government or the government's cabinet secretary.

The milk samples were taken on May 12.

Niigata Prefecture is on the Japan Sea side. Kashiwazaki City, where radioactive cesium was detected from the milk, has Kashiwazaki-Kariwa Nuclear Power Plant, but TEPCO says cesium was from Fukushima I Nuke Plant.

Well, the prevailing wind has switched, and now the plume from Fukushima I is often going inland, and sometimes all the way across to the Japan Sea. It is no surprise that radioactive cesium has been detected in Niigata. There is no escaping the radioactive particles.

(Picture shows the Nagatori railroad station. Nagatori is one of the two locations where cesium was detected from milk.)

From Mainichi Shinbun Japanese (9:10PM JST 6/14/2011):

東京電力は14日、新潟県柏崎市内で採取した牛乳から微量の放射性セシウムを検出したと発表した。検出量は原乳1リットルあたり最大0.046ベク レルで、内閣府原子力安全委員会の指針が定める摂取制限の約4000分の1の値という。柏崎刈羽原発からは放射性物質の漏えいはなく、東電は福島第1原発 から飛散したものとみている。

TEPCO announced on June 14 that a minute amount of radioactive cesium was detected in the raw milk produced in Kashiwazaki City in Niigata Prefecture. The amount was maximum 0.046 becquerel/liter, about 1/4000 of the limit set by the Nuclear Safety Commission. There has been no radioactive materials leak from Kashiwazaki-Kariwa Nuclear Power Plant, and TEPCO believes cesium came airborne from Fukushima I Nuclear Power Plant.

 5月12日に柏崎市長鳥と同市北条の2カ所で採取した牛乳を測定したところ、セシウム134が1リットル当たり0~0.025ベクレル、セシウム 137が同0.021~0.025ベクレル検出された。東電は柏崎刈羽原発の周辺自治体との安全協定に基づき、定期的に放射性物質の調査を実施している。

The milk samples taken in Nagatori and Kitajo districts of Kashiwazaki City on May 12 were tested. Cesium-134 was detected at 0 to 0.025 becquerel/liter, and cesium-137 was detected at 0.021 to 0.025 becquerel/liter. TEPCO conducts regular surveys of radioactive materials in the area around Kashiwazaki-Kariwa Nuclear Power Plant, according to the agreement with the local municipalities.

 東電の松本純一原子力・立地本部長代理は「改めて事故の大きさを認識している。他の農作物や福島県内でも測定を検討したい」としている。

TEPCO's Junichi Matsumoto said, "We again recognize the enormity of this accident. We will consider testing the other agricultural crops [in Niigata?] and testing [the milk?] in Fukushima Prefecture."
