#Fukushima I Nuke Plant: Full of Untrained, Migrant Workers, TEPCO Says Subcontractors ... - 0 views

  • Tokyo Shinbun is a regional newspaper covering Kanto region of Japan. It has been reporting on the Fukushima accident and resultant radiation contamination in a more honest and comprehensive manner than any national newspaper. (Their only shortcoming is that their links don't seem to last for more than a week.)Their best coverage on the subject, though, is not available digitally but only in the printed version of the newspaper. But no worry, as there is always someone who transcribes the article and post it on the net for anyone to see.
  • In the 2nd half of the January 27 article, Tokyo Shinbun details what kind of workers are currently working at Fukushima I Nuclear Power Plant: migrant workers young (in their 20's) and not so young (in their 60's), untrained, $100 a day. Some of them cannot even read and write.
  • Right now, 70% of workers at the plant are migrant contract workers from all over Japan. Most of them have never worked at nuke plants before. The pay is 8000 yen to 13,000 yen [US$104 to $170] per day. Most of them are either in their 20s who are finding it difficult to land on any job, or in their 60s who have "graduated" from the previous jobs."

  • Low wages
  • The relationship between the cause of Mr. Osumi's death and radiation exposure is unknown. However, it is still the radiation exposure that is most worrisome for the workers who work at Fukushima I Nuke Plant to wind down the accident. The radiation exposure limit was lowered back to the normal "maximum 50 millisieverts per year" and "100 millisieverts in 5 years" on December 16 last year. It was done on the declaration of "the end of the accident" by Prime Minister Noda that day.
  • The radiation exposure limit was raised to 250 millisieverts per year right after the accident, as a special measure. The Ministry of Health and Labor argued that the number was based on the international standard for a severe accident which was 500 millisieverts. But the real purpose was to increase the number of hours that can be put in by the workers and to increase the number of workers to promptly wind down the accident.
  • However, as the prime minister wanted to appeal "the end of the accident", the limit was lowered back to the normal limit.
  • According to TEPCO, the radiation exposure levels of workers exceeded [annualized?] 250 millisieverts in some cases right after the accident, but since April it has been within 100 millisieverts.
  • However, the workers voice concerns over the safety management. One of the subcontract workers told the newspaper:
  • He also says the safety management cannot be fully enforced by TEPCO alone, and demands the national government to step in. "They need to come up with the management system that include the subcontract workers. Unless they secure the [safe] work environment and work conditions, they cannot deal with the restoration work that may continue for a long while."
  • From Tokyo Shinbun (1/27/2012):(The first half of the article is asbout Mr. Osumi, the first worker to die in May last year after the plant "recovery" work started. About him and his Thai wife, please read my post from July 11, 2011.)
  • Then the workers start working at the site. But there are not enough radiation control personnel who measure radiation levels in the high-radiation locations, and warn and instruct the workers. There are too many workers because the nature of the work is to wind down the accident. There are workers who take off their masks or who smoke even in the dangerous [high radiation] locations. I'm worried for their internal radiation exposures."
  • In the rest area where the workers eat lunch and smoke, the radiation level is 12 microsieverts/hour. "Among workers, we don't talk about radiation levels. There's no point."
  • The worker divulged to us, "For now, they've managed to get workers from all over Japan. But there won't be enough workers by summer, all bosses at the employment agencies say so." Local construction companies also admit [to the scarcity of workers by summer.]
  • "Local contractors who have been involved in the work at Fukushima I Nuclear Power Plant do not work there any more. It's dangerous, and there are jobs other than at the nuke plant, such as construction of temporary housing. The professional migrant workers who hop from one nuclear plant to another all over Japan avoid Fukushima I Nuke Plant. The pay is not particularly good, so what is the point of getting high radiation to the max allowed and losing the opportunity to work in other nuclear plants? So, it's mostly amateurs who work at the plant right now. Sooner or later, the supply of workers will dry up."
  • As to the working conditions and wage levels of the subcontract workers, TEPCO's PR person explains, "We believe the subcontracting companies are providing appropriate guidance." As to securing the workers, he emphasizes that "there is no problem at this point in sourcing enough workers. We will secure necessary workers depending on how the work progresses."
  • However, Katsuyasu Iida, Director General of Tokyo Occupational Safety and Health Center who have been dealing with the health problems of nuclear workers, points out, "Workers are made to work in a dangerous environment. The wage levels are going down, and there are cases of non-payment. It is getting harder to secure the workers."
  • As to the safety management, he said, "Before you start working at a nuclear power plant, you have to go through the "training before entering radiation control area". But in reality the training is ceremonial. The assumptions in the textbook do not match the real job site in an emergency situation. There were some who could not read, but someone else filled in the test for them at the end of the training."
  • Memo from the desk [at Tokyo Shinbun]: Workers at Fukushima I Nuke Plant are risking their lives. Some are doing it for 8000 yen per day. A councilman who also happens to work for TEPCO earns more than 10 million yen [US$130,000] per year. Executives who "descended from heaven" to cushy jobs in the "nuclear energy village" are alive and well. To move away from nuclear power generation is not just about energy issues. It is to question whether we will continue to ignore such "absurdity".
  • Well said. Everybody in the nuclear industry in Japan knew that the industry depended (still does) on migrant workers who were (still are) hired on the cheap thorough layer after layer of subcontracting companies. Thanks to the Fukushima I Nuclear Plant accident, now the general public know that. But there are plenty of those who are still comfortable with the nuclear power generated by the nuclear power plants maintained at the expense of such workers and see nothing wrong with it.

Hokkaido Governor Allows the Re-Start of Tomari Nuke Plant Reactor 3 [16Aug11] - 0 views

Idaho Samizdat: Nuke Notes: Associated Press Nukes the NRC on Reactor Safety [20Jun11] - 0 views

  • On June 20 the Associated Press published the results of a year long investigative report on safety at nuclear reactors in the U.S. It is a major effort by an experienced journalist and will receive wide attention. Coming on the heels of the Fukushima crisis on Japan, the first of two article contains some strong allegations. AP's investigative reporter Jeff Donn writes that the Nuclear Regulatory Commission has watered down safety regulations in order to keep older reactors like Oyster Creek open beyond 40 years.
  • The article, with its spectacular allegations, was swiftly picked up by the mainstream media including USA Today along with video and a picture of an example of reactor corrosion. In a piece titled "Nuke regulator, industry compromise safety to keep reactors running," Donn wrote . . . "Federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening those standards, or simply failing to enforce them, an investigation by The Associated Press has found. Time after time, officials at the U.S. Nuclear Regulatory Commission have decided that original regulations were too strict, arguing that safety margins could be eased without peril, according to records and interviews. The result? Rising fears that these accommodations by the NRC are significantly undermining safety - and inching the reactors closer to an accident that could harm the public and jeopardize the future of nuclear power in the United States."

  • Is all this true? Or is it contrary to what many nuclear professionals know to be the case with regulation of the nation's 104 reactors? I turned to John Bickel, who's impeccable credentials include several decades of nuclear engineering experience backed by advanced degrees in the field
  • Bickel has 36 years experience in the US and International nuclear engineering profession, specializing in reliability and risk assessment. He has a Masters Degree and PhD in nuclear engineering from Rensselaer Polytechnic Institute. ~ John Bickel, left, attending a meeting of the OECD Nuclear Energy Agency in Paris, where he chairs the special working group on Defense in Depth of Electrical Systems (DIDELSYS) ~ I asked Bickel what he thought of the AP article. Here are some highlights of what he said in a series of email exchanges. Bickel agreed to let me post his personal email comments here. Also, he agreed to let me post his contact information at the end of this blog post so that AP, or anyone else in the media, could contact him for confirmation. Here’s what he said. "I had hoped for more insight from a prestigious organization such as AP. Their article entitled: “US nuke regulators weaken safety rules” is pretty sloppy and indicative of the fact AP failed to research much of what they have written about."

Fuel Assembly Covers Found Cracked and Discolored in SFP of Tsuruga Nuke Plant Reactor ... - 0 views

  • Reactor 1 of Tsuruga Nuclear Power Plant in Tsuruga City, Fukui Prefecture, operated by Japan Atomic Power Company, is the very first light-water reactor (by GE) built in Japan, and the 7th oldest commercial reactor in the world (as of January 2012).
  • (Fukushima I Nuke Plant's Reactor 1 is the second oldest, after Tsuruga's Reactor 1.) Reactor 2 of Tsuruga Nuclear Power Plant (pressurized-water reactor by Mitsubishi Heavy Industries) may be sitting on top of an active fault. Both reactors have been stopped due to scheduled maintenance.
  • Japan Atomic Power Company announced on August 17 that they found cracks and discoloration in 9 metal covers that cover fuel assemblies in Reactor 1 at Tsuruga Nuclear Power Plant (Tsuruga City, Fukui Prefecture) which has been stopped [for maintenance]
  • ...3 more annotations...
  • The metal covers are in the Spent Fuel Pool, and the cracks were found at the welded parts.
  • The [cracks and discoloration] are all minor, and there is no effect on the environment, according to the operator.
  • I think what Yomiuri is talking about ("metal covers") is a channel box that houses fuel assemblies. For Onagawa Nuke Plant's channel boxes, apparently damaged by the March 11, 2011 earthquake, read my post from July this year.

Post-Nuke Reconstruction Plan for Fukushima Prefecture: World-Class Radiation Medicine,... - 0 views

  • When the governor of Fukushima started to say "post-nuke", I thought "OK, he must have found a new way to benefit from the close ties with the national government, other than nuke, or in addition to nuke."According to Yomiuri Shinbun, the latest and final version of the Kan administration's plan for recovery and reconstruction after the March 11 earthquake/tsunami for Fukushima Prefecture will include a host of government research institutions going to Fukushima, with the related industries - heavy electric, utilities, pharmaceutical, etc. - tagging along.
  • Dr. Shunichi "100 millisieverts are no problem" Yamashita is already in Fukushima, salivating at the unique, world-first opportunity to study the long-term effect of radiation on children. Also, Fukushima University and the Japan Atomic Energy Agency, of Monju fame, have signed an agreement to cooperate in research and development of the world-class decontamination technology, among others. (Links are in Japanese.)That the government research institutions rushing to Fukushima makes me wonder if the whole plan is one gigantic experiment using the land, water, air, people, animals, crops, forests and mountains in Fukushima to develop world-class technologies in radiation medicine and decontamination, and renewable energy that the government and the industries can later capitalize on.
  • Yomiuri Shinbun (3:03AM JST 7/27/2011)
  • ...4 more annotations...
  • The final version of the recovery and reconstruction plan that the government was to submit by the end of this month was revealed on July 26.
  • The plan will include the research and development centers for health care and renewable energy in Fukushima Prefecture, which suffers damages from the nuclear plant accident. The government will support the recovery by sending the government research institutions to Fukushima. For residents who cannot rebuild their homes easily, the government will provide the "disaster public housing". The government will set up the headquarters for recovery and reconstruction on July 29, and formally decide on the plan.
  • In the final version of the plan, it is clearly stated that "the national government will be responsible" in recovery and reconstruction from a nuclear disaster. As to the decontamination of the soil and the disposal of disaster debris, the plan says [the government] will "take necessary measures". It also mentions the creation of facilities for the "world-class pharmaceutical and medical equipment research and development" and the "world-class renewable energy research" in Fukushima Prefecture, which are to attract the related industries. For the residents who have lost their homes, the government will provide the "disaster public housing", which will be sold later to those who want to purchase the homes under the scheme.So here's one answer to the question posed by a resident in the youtube video below that captured the confrontation between the Fukushima residents and the national government officials over evacuation:
  • "People in Fukushima have a right to avoid the radiation and live a healthy life, too. Don't you think so?"Well, the government needs them inside Fukushima for all these grand projects. Besides, the government doesn't care about that right for anyone outside Fukushima either.

#Fukushima I Nuke Plant: Water Entombment Is Back on the Table [01Sept11] - 0 views

  • Remember the time when the TEPCO/government complex pretended that it would fill the Containment Vessels of Reactors 1, 2 and 3 with water to cool the Reactor Pressure Vessels inside? It was late April, TEPCO started to pour an enormous amount of water in the RPV of Reactor 1 to fill the Vessel (as the water would leak into the CV). The operation was dubbed "water entombment".
  • We know how it quickly ended. TEPCO finally managed to actually measure the water level inside the CV and RPV of Reactor 1, and found that there was hardly any water in either of them - i.e. both the CV and the RPV of Reactor 1 were broken, kaput. Of 10,000 tonnes of water that TEPCO poured into the CV of Reactor 1, 3,000 tonnes were discovered in the basement.
  • But now, the water entombment is back in discussion in conjunction with decommissioning the reactors at Fukushima I Nuclear Power Plant, according to Mainichi Shinbun (8/31/2011).
  • ...3 more annotations...
  • According to Mainichi, the plan submitted by TEPCO to a special committee of the Nuclear Safety Commission calls for the following steps: Clean up highly radioactive debris inside the reactor buildings;Identify and repair the damage to the Containment Vessels and the reactor buildings;Fill the Containment Vessels with water;Open the top lid of the Reactor Pressure Vessels and remove the melted fuel.
  • The NSC committee will consider the plan, and the government will decide on the final plan by January 2012. My questions: Step No.1: How? By whom? Step No.2: How? By whom? Step No.3: What's the point again? Step No.4: What melted fuel?
  • And no one knows, or rather, no one cares or wants to know, where exactly these melted blobs of fuel rods, control rods, instruments, metals, etc., are right now. TEPCO and the government will proceed as if they remain at the bottom of the Containment Vessel of each Reactor, if not still within the RPV. Inside the reactor buildings there are at least several spots as identified by TEPCO where the radiation levels are measured in sieverts/hour. Who is going to do the cleanup work, not to mention repairing the CVs and the building (I suppose they are thinking about the concrete foundations)?

#Fukushima I Nuke Plant: 450 Tonnes of Groundwater Per Day Seeping into Reactor/Turbine... - 0 views

  • Since the end of June when the contaminated water treatment system started the operation, total 50,000 tonnes of groundwater have seeped into the reactor buildings and turbine buildings at Fukushima I Nuke Plant. Now, the total amount of contaminated water (highly contaminated water plus not-so-highly contaminated, treated water) at the plant has grown from 127,000 tonnes at the end of June to 175,000 tonnes as of October 18, according to Asahi Shinbun.Does TEPCO have any plan to stop the flow of groundwater into the reactor buildings and turbine buildings, which just adds to the amount of highly contaminated water to be treated and stored? TEPCO is fast running out of storage space, even with cutting down more trees to make room for the storage tanks.Other than spraying the low-contamination, treated water on the premise, the answer is no. No plan, as TEPCO is running out of money that it is willing to spend on Fukushima I Nuke Plant.From Asahi Shinbun (10/19/2011):
  • It has been discovered that the contaminated water has increased by 40% in 4 months inside the reactor buildings and turbine buildings at Fukushima I Nuclear Power Plant, with the inflow of ground water of about 50,000 tonnes. The flow still continues. TEPCO may run out of storage space for the treated, still-contaminated, water. There is also a possibility of the highly contaminated water overflowing from the buildings if a problem at the water treatment facility and a heavy rain coincide.
  • According to the calculation done by Asahi Shinbun based on the data published by TEPCO, about 450 tonnes of ground water per day have been flowing into the buildings of Reactors 1 through 4 since the end of June when the contaminated water treatment facility started the operation. It is considered that there are damages in the walls of the buildings.
  • ...7 more annotations...
  • The amount of groundwater into the buildings fluctuates with the rainfall. At the end of September when it rained heavily because of a typhoon, the amount of ground water doubled, and about 7,700 tonnes of water seeped into the buildings in that week.
  • The groundwater would mix with the contaminated water in the basement of the buildings, and this highly contaminated water is being sent to the water treatment facility. After the density of radioactive materials in the water is lowered and salt removed, the treated water is being used for cooling the reactors.
  • When the circulatory water injection and cooling system started in late June, there were 127,000 tonnes of contaminated water (highly contaminated water plus the treated water with low contamination). However, as the result of the groundwater inflow, there are now 175,000 tonnes of contaminated water, a 40% increase, as of October 18. None of the water could be released outside the plant.
  • Concentrated, highly saline waste water after the desalination process is stored in the special tanks. As more water is processed, more tanks are needed. TEPCO is installing 20,000 tonnes storage tanks every month. To secure the space for the tanks the company has been cutting down the trees in the plant compound. There is a system to evaporate water to reduce the amount of waste water, but it is not currently used.
  • The water level in the turbine buildings where the highly contaminated water after the reactor cooling accumulates is 1 meter below the level at which there is a danger of overflowing. It is not the level that would cause immediate overflow after a heavy rain. However, if the heavy rain is coupled with a trouble at the water treatment system that hampers the water circulation, the water level could rise very rapidly.
  • The treatment capacity of the water treatment facility is 1,400 tonnes per day. TEPCO emphasizes that the facility is running smoothly and the circulatory water injection system is stable. However, if the current situation continues where groundwater keeps coming into the buildings that needs to be treated, the water treatment facility will be taxed with excess load, which may cause a problem.
  • It is difficult to stop the inflow of groundwater completely, and TEPCO is not planning any countermeasure construction. Regarding the continued inflow of groundwater into the buildings, TEPCO's Junichi Matsumoto says, "We have to come up with a more compact water treatment system in which we can circulate water without using the basements of the buildings. Otherwise we would be stuck in a situation where we have to treat the groundwater coming into the basements." However, there is no prospect of fundamentally solving the problem.And there will be no such prospect, as TEPCO is now proven to be very good at looking the other way. Over 10 sieverts/hour ultra-hot spot? Not a problem, we will just cordon off the area. What is causing 10 sieverts/hour radiation? Why it's not our problem. How much over 10 sieverts/hour? We don't know because we don't measure such things. High hydrogen concentration in the pipe? Not a problem, we will just blow nitrogen gas. What is causing the high hydrogen concentration? It's not our problem. A worker died after 1 week of work at the plant. Why? It's not our problem, it's the subcontractor's problem...

#Fukushima I Nuke Plant Reactor 1 Balloon Survey of 5th Floor Was Unsuccessful |[08Aug12] - 0 views

  • According to TEPCO's press release on 8/8/2012, the balloon couldn't pop out onto the operating floor (5th floor) because it was stopped by a cable on the 4th floor. The balloon did take photographs of the 4th floor. The purpose of the survey (not fulfilled by this project) was to see what the 5th floor was like, in order to prepare for the future removal of fuel assemblies from the Spent Fuel Pool. (See my post from July 23, 2012.)
  • 5 TEPCO employees and 14 affiliate company workers did the work, for about 35 minutes, receiving maximum 1.54 millisievert for the shortened work.
  • Purpose The investigation was conducted to understand the current condition of Unit 1 operating floor (5th floor) and provide inputs to the consideration of fuel removal from the spent fuel pool.

#Radiation in Japan Spreads: Wheat, Rapeseeds in Fukushima, Rice Hay Outside Fukushima ... - 0 views

  • Fukushima Prefecture announced on July 25 that radioactive cesium exceeding the provisional limit was detected from the wheat harvested at a farm in Hirono-machi [23 kilometers south of Fukushima I Nuke Plant] in Fukushima Prefecture. The prefectural government says the wheat hasn't been sold in the market. It is the first time that radioactive cesium exceeding the limit has been detected in wheat.
  • According to the prefectural government, 630 becquerels/kg of radioactive cesium was found in a sample taken on July 19. The prefectural government has asked the farm to withhold shipment on a voluntary basis. Fukushima Prefecture ranks No. 25th in wheat production in Japan, with 651 tonnes produced last year.
  • Also, 720 becquerels/kg of radioactive cesium has been detected in the rapeseeds harvested by a farm in Tamura City [41 kilometers west of Fukushima I Nuke Plant] in Fukushima. The rapeseeds haven't been shipped, and the prefectural government has asked the farm to withhold shipment on a voluntary basis.
  • ...4 more annotations...
  • Don't overly count on the statement that these crops haven't yet been sold in the market. That's as far as the farmer has told the government, or as far as the government can tell, which may not be much.
  • Also, for those who are wondering: When the government asks a farmer to withhold shipment "on a voluntary basis", it means that technically the farmer is free to ship but the government expects the farmer not to ship, and the farmer will not get compensated for not shipping because it is done on a "voluntary basis" - i.e. on his own judgment, technically. The government thus saves money. It is a code word used by the government that means "You are not supposed to ship, but we won't pay you for your potential loss."Also from Asahi (4:49AM JST 7/26/2011):
  • Ibaraki Prefecture announced on July 25 that 64,000 becquerels/kg of cesium was detected from the rice hay collected at a farm in Takahagi City [83 kilometers south of Fukushima I Nuke Plant] in Ibaraki Prefecture. If reconstituted, the level of radioactive cesium in the hay would be 14,500 becquerels/kg, more than 48 times the national safety limit [for the feed] of 300 becquerels/kg. No cow has been shipped from this farm.
  • So now in Ibaraki. The US government's decision to evacuate its citizens outside 80 kilometers radius from Fukushima I Nuke Plant, which has been criticized by some in the US media as "overreaction", has turned out to be the very prudent thing to do; maybe that wasn't even far enough, considering Takahagi City is outside that zone.

#Fukushima I Nuke Plant Worker: No Steam Gushing From Cracks, But There Are Many 10-Plu... - 0 views

  • The anonymous Fukushima I Nuke Plant worker whom I featured before several times tweets on the information, yet to be substantiated, related by an independent journalist Kota Kinoshita on his blog on August 15. Mr. Kinoshita related the information only because he had heard the similar information from his government source. What is that information? That there is steam gushing out of cracks on the ground, and that there are 6 locations that exceed 10 sieverts/hr radiation. 1. About "steam gushing out from cracks on the ground": In Mr. Kinoshita's blog:
  • It was early August, around 9PM. A worker at Fukushima I Nuke Plant sent an email to his local contact, saying "Steam gushing out of cracks on the ground. The area is foggy with steam, and the workers evacuated temporarily. Some kind of reaction may be occurring underground. Watch out for radiation level depending on the wind direction".
  • From the information source within the government, "I've heard about the steam coming out from the ground, and I am concerned". Fukushima worker's tweet:
  • ...5 more annotations...
  • I think that is true. But those are the locations that have been measured. I think there are many more.Mr. Kinoshita's blog has this bit of "rumor" from his worker at the plant:
  • As I have said before, I have never seen, or heard about, such steam.It's possible that he doesn't know but someone else may know. 2. About locations that exceed 10 sieverts/hr: In Mr. Kinoshita's blog:
  • The same worker] also told [his contact] that there are 6 locations that exceed 10,000 millisievert/hr [10 sieverts/hr], unlike what TEPCO has announced. Fukushima worker's tweet:
  • There are several cracks on the ground near the Containment Vessel, and the steam is coming out from them, not on a regular basis but sporadically. Wait, does that mean the floor of the reactor building is cracked? He doesn't say which reactor. And Fukushima worker has another tweet that says:
  • In the reactor buildings of Reactors 1, 2 and 3, there are many spots that measure even higher [than 10 sieverts/hr] and we can't go near them.So much for the plant being stable. But so far, the information is unsubstantiated (i.e. not admitted, or denied, by officials at TEPCO or the government). Speaking of the government, it will allow the residents in Okuma-machi and Futaba-machi, where the plant is located, to temporarily return to their homes later this month now that the plant is stable.

#Fukushima I Nuke Plant: TEPCO Ready to Drive Carbon-Based Workers Even Harder [11Sep11] - 0 views

  • TEPCO announced on September 9 that 6 workers entered the reactor building of Reactor 3 at Fukushima I Nuclear Power Plant, and installed a water gauge to measure the amount of contaminated water in the basement. According to the company, the radiation exposure of the 6 workers was between 0.33 to 5.26 millisieverts. The measurement using the water gauge is set to start on or after September 12.
  • ... TEPCO also disclosed the plan to start removing the debris from the upper floors of Reactors 3 and 4. The work will start in Reactor 3 on September 10, and it will start in Reactor 4 within this month. Upper floors of Reactors 3 and 4 are littered with damaged ceiling panels and exterior wall panels, and it is hoped that the spread of radioactive materials will be suppressed by removing the debris.
  • Removing the debris will stir up the radioactive materials instead of suppressing them, won't it? Not to mention exposing the workers to an inadvertent 10-plus sieverts/hour super hot spot, as it happened near the exhaust stack between Reactors 1 and 2?From the tweets by the worker at Fukushima I Nuke Plant, it is evident that TEPCO is fast running out of money (to spend on the accident, apparently not on its retiring executives) and carbon-based workers to do further work. The worker also tweeted a week or so ago that the construction people were active, already clearing debris in Reactor 4.
  • ...2 more annotations...
  • The construction companies (Kajima, Taisei are at Fukushima, I think) are the worst offenders in Japan traditionally when it comes to exploiting the temporary, contract workers. Apparently, according to the tweets by the worker mentioned above, there are workers hired by them who know little about radiation danger at Fukushima I Nuke Plant where a 10-sieverts/hr extreme hot spot can be just around the corner.Perhaps I shouldn't say "TEPCO" in the title. It is not really TEPCO who is ready and willing to expose workers to high radiation by driving them to clean up the place. TEPCO asks its main subcontractors (in this case, large construction companies) to figure out a way to complete the task of clearing the debris and tells them the budget. The subcontractors tell their subcontractors , who then tell their subcontractors....(up to 6th or 7th degree removed from TEPCO) to figure out a way, and finally some fresh warm bodies are brought in and put to work. They may or may not know the risk. The task is simple, just removing the debris from the floors with full protection gear and face mask, climbing up and down the stairs as the elevators are broken. All they need is physical strength.
  • (By the way, he also says the flashing bright light in TEPCO's livecam at night is from the construction people. Not that you have to believe him necessarily, but just for your information.)By putting in many layers of subcontracting, everyone can deny that they are willingly and actively putting workers at risk.Ah the country is broken (and broke), and mountains and rivers are not the same any more, but the subcontracting and "dango" (collusion) are hard to die in Japan.

Photographs of 60,000-Strong Anti-Nuke Demonstration in Tokyo [20Sep11] - 0 views

  • Looking at this aerial photographs taken by Mainichi Shinbun (one of the better ones in terms of even coverage on nuke issues in Japan; another is Tokyo Shinbun), it sure looks more than 60,000 to me. People who actually participated in the event seemed to have the same impression as mine (on this blog comment sections, and on twitter), that it was far bigger than official number by the police (30,000).Mainichi quotes the organizers' number of 60,000 people, and also quotes the number by the police (30,000):
  • Meanwhile, photos from Germany's Spiegel and France's Le Monde, who used the photos from AP and other agencies. Spiegel puts the number at 60,000:
  • and Yomiuri, who says "more than 30,000 people gathered" (exactly the police official estimate):
  • ...3 more annotations...
  • Asahi, slightly better perspective but not much, but the article does quite the organizers' number, 60,000 people:
  • and the US paper Forbes, without photo, says "tens of thousands of people marched", but the article title declares "Thousands march against nuclear power in Tokyo". Thousands??Many participants in Japan are indignant that their demonstration was called a "parade", as if this was some festival attraction. Well, give the media time to learn. To me, it's amazing that the MSMs like Yomiuri and Asahi covered the event at all, and even had photographs. Asahi and Mainichi sent in their own photographers for the event. (Yomiuri's looks like Jiji Tsushin's photo.) I would take it as a sign that the anti-nuke movement may be crossing the threshold in Japan in terms of the number of people, and the MSMs cannot simply ignore anymore.
  • Calling it a "parade" and using the lowest official estimate by the police as the number of participants is a classic way to belittle a movement.

CPS must die [24Oct07} - 0 views

  • Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
  • Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
  • Consider, South Texas Project Plants 1&2, which send us almost 40 percent of our power, were supposed to cost $974 million. The final cost on that pair ended up at $5.5 billion. If the planned STP expansion follows the same inflationary trajectory, the price tag would wind up over $30 billion. Applications for the Matagorda County plants were first filed with the Atomic Energy Commission in 1974. Building began two years later. However, in 1983 there was still no plant, and Austin, a minority partner in the project, sued Houston Power & Lighting for mismanagement in an attempt to get out of the deal. (Though they tried to sell their share several years ago, the city of Austin remains a 16-percent partner, though they have chosen not to commit to current expansion plans).

  • CPS didn’t just pull nukes out of a hat when it went looking for energy options. CEO Milton Lee may be intellectually lazy, but he’s not stupid. Seeking to fulfill the cheap power mandate in San Antonio and beyond (CPS territory covers 1,566 square miles, reaching past Bexar County into Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties), staff laid natural gas, coal, renewables and conservation, and nuclear side-by-side and proclaimed nukes triumphant. Coal is cheap upfront, but it’s helplessly foul; natural gas, approaching the price of whiskey, is out; and green solutions just aren’t ready, we’re told. The 42-member Nuclear Expansion Analysis Team, or NEAT, proclaimed “nuclear is the lowest overall risk considering possible costs and risks associated with it as compared to the alternatives.” Hear those crickets chirping?
  • NEAT members would hold more than a half-dozen closed-door meetings before the San Antonio City Council got a private briefing in September. When the CPS board assembled October 1 to vote the NRG partnership up or down, CPS executives had already joined the application pending with the U.S. Nuclear Regulatory Commission. A Supplemental Participation Agreement allowed NRG to move quickly in hopes of cashing in on federal incentives while giving San Antonio time to gather its thoughts. That proved not too difficult. Staff spoke of “overwhelming support” from the Citizen’s Advisory Board and easy relations with City staff. “So far, we haven’t seen any fatal flaws in our analysis,” said Mike Kotera, executive vice president of energy development for CPS. With boardmember and Mayor Phil Hardberger still in China inspecting things presumably Chinese, the vote was reset for October 29.
  • No one at the meeting asked about cost, though the board did request a month-by-month analysis of the fiasco that has been the South Texas Project 1&2 to be delivered at Monday’s meeting. When asked privately about cost, several CPS officers said they did not know what the plants would run, and the figure — if it were known — would not be public since it is the subject of contract negotiations. “We don’t know yet,” said Bob McCullough, director of CPS’s corporate communications. “We are not making the commitment to build the plant. We’re not sure at this point we really understand what it’s going to cost.” The $206 million outlay the board will consider on Monday is not to build the pair of 1,300-megawatt, Westinghouse Advanced Boiling Water Reactors. It is also not a contract to purchase power, McCullough said. It is merely to hold a place in line for that power.
  • It’s likely that we would come on a recurring basis back to the board to keep them apprised of where we are and also the decision of whether or not we think it makes sense for us to go forward,” said Larry Blaylock, director of CPS’s Nuclear Oversight & Development. So, at what point will the total cost of the new plants become transparent to taxpayers? CPS doesn’t have that answer. “At this point, it looks like in order to meet our load growth, nuclear looks like our lowest-risk choice and we think it’s worth spending some money to make sure we hold that place in line,” said Mark Werner, director of Energy Market Operations.
  • Another $10 million request for “other new nuclear project opportunities” will also come to the board Monday. That request summons to mind a March meeting between CPS officials and Exelon Energy reps, followed by a Spurs playoff game. Chicago-based Exelon, currently being sued in Illinois for allegedly releasing millions of gallons of radioactive wastewater beneath an Illinois plant, has its own nuclear ambitions for Texas. South Texas Project The White House champions nuclear, and strong tax breaks and subsidies await those early applicants. Whether CPS qualifies for those millions remains to be seen. We can only hope.
  • CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
  • After Unit 1 came online in 1988, it had to be shut down after water-pump shaft seared off in May, showering debris “all over the place,” according to Nucleonics Week. The next month two breakers failed during a test of backup power, leading to an explosion that sheared off a steam-generator pump and shot the shaft into the station yard. After the second unit went online the next year, there were a series of fires and failures leading to a half-million-dollar federal fine in 1993 against Houston Power. Then the plant went offline for 14 months. Not the glorious launch the partnership had hoped for. Today, CPS officials still do not know how much STP has cost the city, though they insist overall it has been a boon worth billions. “It’s not a cut-and-dried analysis. We’re doing what we can to try to put that in terms that someone could share and that’s a chore,” said spokesman McCollough. CPS has appealed numerous Open Records requests by the Current to the state Attorney General. The utility argues that despite being owned by the City they are not required to reveal, for instance, how much it may cost to build a plant or even how much pollution a plant generates, since the electricity market is a competitive field.
  • How do we usher in this new utopia of decentralized power? First, we have to kill CPS and bury it — or the model it is run on, anyway. What we resurrect in its place must have sustainability as its cornerstone, meaning that the efficiency standards the City and the utility have been reaching for must be rapidly eclipsed. Not only are new plants not the solution, they actively misdirect needed dollars away from the answer. Whether we commit $500 million to build a new-fangled “clean-coal” power plant or choose to feed multiple billions into a nuclear quagmire, we’re eliminating the most plausible option we have: rapid decentralization.
  • A 2003 study at the Massachusetts Institute of Technology estimates the cost of nuclear power to exceed that of both coal and natural gas. A U.S. Energy Information Administration report last year found that will still be the case when and if new plants come online in the next decade. If ratepayers don’t pay going in with nuclear, they can bet on paying on the way out, when virtually the entire power plant must be disposed of as costly radioactive waste. The federal government’s inability to develop a repository for the tens of thousands of tons of nuclear waste means reactors across the country are storing spent fuel in onsite holding ponds. It is unclear if the waste’s lethality and tens of thousands of years of radioactivity were factored into NEAT’s glowing analysis.
  • The federal dump choice, Nevada’s Yucca Mountain, is expected to cost taxpayers more than $60 billion. If it opens, Yucca will be full by the time STP 3&4 are finished, requiring another federal dump and another trainload of greenbacks. Just the cost of Yucca’s fence would set you back. Add the price of replacing a chain-link fence around, let’s say, a 100-acre waste site. Now figure you’re gonna do that every 50 years for 10,000 years or more. Security guards cost extra. That is not to say that the city should skip back to the coal mine. Thankfully, we don’t need nukes or coal, according to the American Council for an Energy-Efficient Economy, a D.C.-based non-profit that champions energy efficiency. A collection of reports released this year argue that a combination of ramped-up efficiency programs, construction of numerous “combined heat and power” facilities, and installation of on-site renewable energy resources would allow the state to avoid building new power plants. Texas could save $73 billion in electric generation costs by spending $50 billion between now and 2023 on such programs, according to the research group. The group also claims the efficiency revolution would even be good for the economy, creating 38,300 jobs. If ACEEE is even mostly right, plans to start siphoning millions into a nuclear reservoir look none too inspired.
  • To jump tracks will take a major conversion experience inside CPS and City Hall, a turning from the traditional model of towering plants, reels of transmission line, and jillions of dependent consumers. CPS must “decentralize” itself, as cities as close as Austin and as far away as Seattle are doing. It’s not only economically responsible and environmentally sound, but it is the best way to protect our communities entering what is sure to be a harrowing century. Greening CPS CPS is grudgingly going greener. In 2004, a team of consultants, including Wisconsin-based KEMA Inc., hired to review CPS operations pegged the utility as a “a company in transition.” Executives interviewed didn’t understand efficiency as a business model. Even some managers tapped to implement conservation programs said such programs were about “appearing” concerned, according to KEMA’s findings.
  • While the review exposed some philosophical shortcomings, it also revealed for the first time how efficiency could transform San Antonio. It was technically possible, for instance, for CPS to cut electricity demand by 1,935 megawatts in 10 years through efficiency alone. While that would be accompanied with significant economic strain, a less-stressful scenario could still cut 1,220 megawatts in that period — eliminating 36 percent of 2014’s projected energy use. CPS’s current plans call for investing $96 million to achieve a 225-megawatt reduction by 2016. The utility plans to spend more than four times that much by 2012 upgrading pollution controls at the coal-fired J.T. Deely power plant.
  • In hopes of avoiding the construction of Spruce 2 (now being built, a marvel of cleanliness, we are assured), Citizen Oversight Committee members asked KEMA if it were possible to eliminate 500 megawatts from future demand through energy efficiency alone. KEMA reported back that, yes, indeed it was possible, but would represent an “extreme” operation and may have “unintended consequences.” Such an effort would require $620 million and include covering 90 percent of the cost of efficiency products for customers. But an interesting thing happens under such a model — the savings don’t end in 2012. They stretch on into the future. The 504 megawatts that never had to be generated in 2012 end up saving 62 new megawatts of generation in 2013 and another 53 megawatts in 2014. With a few tweaks on the efficiency model, not only can we avoid new plants, but a metaphorical flip of the switch can turn the entire city into one great big decentralized power generator.
  • Even without good financial data, the Citizen’s Advisory Board has gone along with the plan for expansion. The board would be “pennywise and pound foolish” not to, since the city is already tied to STP 1&2, said at-large member Jeannie O’Sullivan. “Yes, in the past the board of CPS had been a little bit not as for taking on a [greater] percentage of nuclear power. I don’t know what their reasons were, I think probably they didn’t have a dialogue with a lot of different people,” O’Sullivan said.
  • For this, having a City-owned utility offers an amazing opportunity and gives us the flexibility to make most of the needed changes without state or federal backing. “Really, when you start looking, there is a lot more you can do at the local level,” said Neil Elliott of the ACEEE, “because you control building codes. You control zoning. You can control siting. You can make stuff happen at the local level that the state really doesn’t have that much control of.” One of the most empowering options for homeowners is homemade energy provided by a technology like solar. While CPS has expanded into the solar incentives field this year, making it only the second utility in the state to offer rebates on solar water heaters and rooftop panels, the incentives for those programs are limited. Likewise, the $400,000 CPS is investing at the Pearl Brewery in a joint solar “project” is nice as a white tiger at a truck stop, but what is truly needed is to heavily subsidize solar across the city to help kickstart a viable solar industry in the state. The tools of energy generation, as well as the efficient use of that energy, must be spread among the home and business owners.
  • Joel Serface, with bulb-polished pate and heavy gaze, refers to himself as a “product of the oil shock” who first discovered renewables at Texas Tech’s summer “geek camp.” The possibilities stayed with him through his days as a venture capitalist in Silicon Valley and eventually led him to Austin to head the nation’s first clean-energy incubation center. Serface made his pitch at a recent Solar San Antonio breakfast by contrasting Texas with those sun-worshipping Californians. Energy prices, he says, are “going up. They’re not going down again.” That fact makes alternative energies like solar, just starting to crack the 10-cent-per-killowatt barrier, financially viable. “The question we have to solve as an economy is, ‘Do we want to be a leader in that, or do we want to allow other countries [to outpace us] and buy this back from them?’” he asked.
  • To remain an energy leader, Texas must rapidly exploit solar. Already, we are fourth down the list when it comes not only to solar generation, but also patents issued and federal research awards. Not surprisingly, California is kicking silicon dust in our face.

Ministry of Education's Quick Learning Curve on Kashiwa's Radioactive Dirt [23Oct11] - 0 views

  • First it was "it cannot be from Fukushima I Nuke Plant" when the radiation measured was 57.5 microsieverts/hour.Then it was "it may be from Fukushima I Nuke Plant, and it may not be" when the density turned out to be 276,000 becquerels/kg of radioactive cesium. But since the density was very high, the suspicion was voiced all around (including me) that someone secretly dumped the radioactive sludge or dirt, possibly from cleaning out his yard, onto that location.The Ministry's current position: "It is highly likely that radioactive cesium is from Fukushima I Nuke Plant, and radioactive cesium has been condensed at that particular location because the storm drain nearby was broken."So radioactive cesium from Fukushima I Nuke Plant has been naturally concentrated by elements, 200 kilometers away from the plant, to the density level on par with those found in Fukushima. The Kashiwa City's dirt contains almost as much radioactive cesium in the dirt in the location in Watari District (link is in Japanese) in Fukushima City where 300,000 becquerels/kg of radioactive cesium was found (also near the drain).
  • Points from the Ministry's announcement on October 23, 2011 "Result of the investigation of Kashiwa City's location with high air radiation" (my translation, not the Ministry's):On receiving the result of the soil analysis on October 22 where maximum 276,000 becquerels/kg of radioactive cesium was detected, the Ministry sent two officials, along with three experts from Japan Atomic Energy Agency on October 23 to Kashiwa City to consult with the local officials in charge of radiation countermeasures.The Ministry's survey of the location included measuring air radiation levels at the location and nearby, and investigating the surroundings to figure out what caused the high radiation level.Survey result:Maximum 2.0 microsieverts/hour 1 meter off the groundMaximum 4.5 microsieverts/hour 50 centimeter off the groundMaximum 15 microsieverts/hour on the ground
  • Typical air radiation levels in the surrounding area at 1 meter off the ground was 0.3 microsievert/hour.A 50-centimeter wide breach was found in the side drain (30-centimeter deep) next to the location with the high air radiation. This breach was close to the spot where cesium-134 (half life 2 years) was detected. We therefore presume that the rainwater containing radioactive cesium that came from the Fukushima I Nuclear Power Plant accident flowed in from the breach in the side drain, and radioactive cesium was condensed and accumulated in the soil at that particular location.Asahi Shinbun (10/23/2011) has the picture of the broken side drain.

Armenian Public Radio: Metsamor Nuke Plant Can Withstand M10 Earthquake [26Oct11] - 0 views

  • The Turkey earthquake, which registered M3 at the plant in Armenia, is nothing, according to the Public Radio of Armenia. However, There's a rumor that radioactive materials have leaked in the surrounding area. (Actually, it is reported by the Iranian state Japanese radio broadcast on October 25, quoting the Turkish newspaper Zaman which supposedly quotes the Turkish government source.)Armenia's Metsamor Nuclear Power Plant is often called "the most dangerous nuke plant in the world", as it is one of the few nuke plants in the world without primary containment structures, and is in the earthquake-prone region without ready access to water as reactor coolant in case of plant damage by the earthquake.
  • From Public Radio of Armenia (10/24/2011):The earthquake in Turkey has not caused and could not have caused any harm to the Armenian Nuclear Power Plant (ANPP), since it is designed to resist an earthquake measuring 9-10 on the Richter scale, the Armenian Ministry of Emergency Situations said in a statement.The epicenter of the earthquake was located about 160 km away from the ANPP, the quake measured 3-5 on the territory of Armenia.It did not cause any damage to any settlement or building on the territory of the Republic of Armenia, the Ministry said.ANPP Director General Gagik Markosyan says the quake measured 2-3 at the plant, adding that the ANPP had been stopped for planned reconstruction works from September 11.

#Fukushima I Nuke Plant: 220 Tonnes, not 45, of Strontium-Contaminated Water? [07Dec11] - 0 views

  • If you look at the photos released so far by TEPCO (see my posts here and here) while being told only 45 tonnes of treated water leaked from the evaporative condensation apparatus (desalination) at Fukushima I Nuclear Power Plant and that only 150 liters (about 40 gallons) of it leaked into the ocean, and wonder "45 tonnes? 150 liters? The numbers look too low", you may be right.The amount of water leaked from the apparatus may be 220 tonnes, not 45 tonnes as widely reported. In this case, one of the first reports by Asahi Shinbun (print/digital print version) may have gotten it right. 45 tonnes just inside the building that houses this apparatus.
  • Let's do some recalculations. 150 liters of the treated water that have leaked into the ocean, according to TEPCO, had 26,000,000,000 becquerels (26 billion becquerels) of radioactive materials (cesium, strontium, etc.). If 750 liters leaked instead (using the ratio of 220 tonnes to 45 tonnes), 130 billion becquerels. If one tonne (1000 liters) leaked, about 173 billion becquerels.The first news of an event in this nuclear disaster has often proven to be right, just like the March 12 announcement by the Nuclear and Industrial Safety Agency that there may have been a core meltdown at Fukushima. (That spokesman was replaced the next day of course.)Anyway, here's Asahi Shinbun's report at 10:47PM on December 4, 2011 (print/digital print version):

#Fukushima I Nuke Plant Reactor 3: Videos of Packbots Cleaning the Guide Rail and Findi... - 0 views

  • First, the video of Packbots' cleaning operation on November 18 of the guide rails to the Containment Vessel hatch in Reactor 3 reactor building 1st floor. As one Packbot wipes the rail and holds the towel up in the air, you see the water is dripping. The droplets look clear, and not sludge-like.
  • By the way, it is false information that the video was taken by a human worker on the scene. No way even TEPCO would knowingly send a carbon-based worker to videotape in 1.3 sievert/hr (as of November 14) environment. (Human workers entering and finding high-radiation spots is another matter.) One Packbot did the cleaning, while the other videotaped the effort by its colleague. Both were remotely operated by carbon-based colleagues from the PCs.And here's the video where Packbots went back the next day (November 19) to the guide rails to inspect the cleaning job and measure the radiation again. We know that they found out their cleaning operation didn't reduce the radiation levels along the rails; the levels went up (see yesterday's post). The guide rails, despite the cleaning operation, look wet:

#Fukushima I Nuke Plant: Workers Knew About the Extremely High Radiation Around Exhaust... - 0 views

  • There may not be any work planned in the area there, BECAUSE RADIATION IS TOO HIGH. There may be no work planned there, but the workers have to go near it to enter the Reactor 1 building. The radiation is so high that the workers, with all their full protection gear and equipment and construction materials they carry, have been running past the area in order to minimize radiation exposure.So it's been known.More information from his tweets:
  • (Someone asked if it's true that TEPCO does not have the survey meter that can measure more than 10 sievert/hr radiation.) I think that's correct. We do have the instrument to measure the radiation of the nuclear fuel rods, but I wonder what happened to that. Broke?(Referring to the area where over 10 sievert/hr radiation has been detected,) the radiation level around the exhaust stacks has been too high to even go near, ever since the accident started. Not just the area around the stack for Reactors 1 and 2, but also the stack for Reactors 3 and 4.
  • Debris are removed by shielded heavy equipment or remote-controlled equipment. That (10+ sievert/hr) spot was found during such operation.
  • ...5 more annotations...
  • We have to run when we go by the stack to enter Reactor 1. That's hard work. My legs hurt already from climbing up and down the stairs in the reactor building. Now I appreciate elevators!
  • All the elevators inside the reactor buildings at Fukushima I Nuke Plant are broken.
  • As to the worker who measured the radiation with the survey meter attached to a stick, Hiroaki Koide of Kyoto University says he must have spent only 1 or 2 seconds near the stack to get 4 millisieverts radiation.Let's see. 2.78 millisieverts for one second, if the radiation was 10 sieverts/hr.
  • Koide thinks the radiation level is impossibly high to be coming from inside the duct or stack. He suspects there is a piece or two of the spent fuel blown out of the Spent Fuel Pool when Reactor 1 and Reactor 3 had hydrogen explosions.He also says the protection suits that workers wear do nothing to protect them from gamma rays, unless they wear lead vests, but even then only marginally.
  • (For more of his comment, there's a transcript of the radio program that he appeared in, in Japanese.)
