Fukushima Forever [21Sep13] - 0 views

  •  
    [...] Much more serious is the danger that the spent fuel rod pool at the top of the nuclear plant number four will collapse in a storm or an earthquake, or in a failed attempt to carefully remove each of the 1,535 rods and safely transport them to the common storage pool 50 meters away. Conditions in the unit 4 pool, 100 feet from the ground, are perilous, and if any two of the rods touch it could cause a nuclear reaction that would be uncontrollable. The radiation emitted from all these rods, if they are not continually cool and kept separate, would require the evacuation of surrounding areas including Tokyo. Because of the radiation at the site the 6,375 rods in the common storage pool could not be continuously cooled; they would fission and all of humanity will be threatened, for thousands of years.

  • book titled Chernobyl: Consequences of the Catastrophe for People and the Environment in a publication called the Annals of the New York Academy of Sciences. The roots of the decision remain murky. Within a few months after the first printing of the book, Ted Rockwell, a long time member of the Academy, started working to convince NYAS leaders that the decision to print was a grave error that was bad for science and posed a significant risk to the reputation of the Academy as a source of sound, peer-reviewed information. As part of his effort, he encouraged the current editor of Annals of the New York Academy of Sciences to appoint reviewers and to post the results of those reviews.

Fukushima: animation explains how fuel rod removal will happen - video [06Nov13] - 0 views

  •  
    A video animation by the operators of the Fukushima plant, the Tokyo Electric Company, shows how 1,534 damaged fuel rods will be removed from the site. A robotic crane will move the rods from a storage pool damaged by March 2011's earthquake and stored more securely in an on-site facility

95% disagree with "Beyond Nuclear". Let's make it 99% [23Oct11] - 0 views

  • 95% disagree with “Beyond Nuclear”. Let’s make it 99% by Rod Adams on October 14, 2011 in Antinuclear activist , Politics of Nuclear Energy , Unreliables , Wind energy Share0 One of the more powerful concepts that I studied in college was called “groupthink.” The curriculum developers in the history department at the US Naval Academy thought it was important for people in training to become leaders in the US Navy learn to seek counsel and advice from as broad a range of sources as possible. We were taught how to avoid the kind of bad decision making that can result by surrounding oneself with yes-men or fellow travelers. The case study I remember most was the ill fated Bay of Pigs invasion where virtually the entire Kennedy Administration cabinet thought that it would be a cakewalk . If Patricia Miller had bothered to do the fact-checking required by journalistic integrity she would have come across this video showing 30 feet of water above the fuel at Fukushima with all of the fuel bundles exactly where they’re supposed to be. Aside: Don’t we live in an amazing world? I just typed “Bay of Pigs groupthink” into my browser search box and instantly hit on exactly the link I needed to support the statement above.

Not everyone, however, has the benefit of early leadership lessons about the danger of believing that a small group of likeminded people can provide actionable advice. Some of the people who are most likely to be victims of groupthink are those who adamantly oppose the continued safe operation of emission-free nuclear power plants. The writers who exclusively quote members of that tiny community have also fallen into the groupthink trap.   On October 8, 2011, the Berkeley Patch, a New Jersey based journal that regularly posts negative stories about Oyster Creek, featured an article titled Petitioners to NRC: Shut Down All Fukushima-Like Nuclear Plants .

For example, the article uses the following example of how antinuclear activists are still trying to spread the myth that the used fuel pools at Fukushima caught fire. Oyster Creek – the oldest nuclear plant in the United States – has generated over 700 tons of high-level radioactive waste, Kevin Kamps of Beyond Nuclear said. “Granted that some of that has been moved into dry cast storage, but the pool remains full to its capacity,” Kamps said. “And this was a re-rack capacity. Much later in terms of quantity of high level radioactive waste than it was originally designed for.” This represents 125 million curies of radioactive cesium-137 and the NRC has reported that up to 100 percent of the hazardous material could be released from a pool fire, Kamps said. “I would like to point out that Fukushima Daiichi units one, two, three and four combined in terms of the inventory of high level radioactive waste in their storage pools does not match some of these reactors I mentioned in terms of how much waste is in these pools,” Kamps said. “So the risks are greater here for boil downs and the consequences of a radioactive fire in these pools.” Fortunately, the people who are not a part of the antinuclear community are finally beginning to recognize their own strength and to realize that they do not have to remain silent while the lies are being spread. Here is how a knowledgable commenter responded to the above segment of the article: If Patricia Miller had bothered to do the fact-checking required by journalistic integrity she would have come across this video showing 30 feet of water above the fuel at Fukushima with all of the fuel bundles exactly where they’re supposed to be.

  • NOTHING happend to the fuel in the pools at Fukushima. I would like to see some evidence other than the word of an activist who frightens kids for a living to support Gunter’s rant about peices of fuel being ejected miles away. From the looks of that video, the fuel didn’t move an inch. There is also a poll associated with the article. The poll discloses that it is completely unscientific, since it allows anyone to vote and is not based on randomly selected participants. However, I think that the results as of 0315 this morning are pretty amusing since the antinuclear opinion piece has been posted for nearly a week.
  • Perhaps this October 12, 2011 post titled Oyster Creek Response that was published on Clean Energy Insight has something to do with the way the results are shaping up with 1029 out of 1080 respondents (95.3%) saying that Oyster Creek should not stop operating. Here is one more example of how inbred the group of antinuclear activists has become. I am talking here about the people who are so adamantly opposed to using nuclear energy that they do not even want existing nuclear plants to keep on producing clean, emission free, low cost electricity. Michael Mariotte of NIRS makes the following extraordinary claim: Ninety-five percent of the people in the world know about Fukushima, Michael Mariotte of the Nuclear Information and Resource Service said.
  • “It took a really extraordinary event for 95 percent of the people in the world to know about it,” he said. “If they know about Fukushima, they know about Mark 1 reactors exploding in the air and releasing toxic radiation across the world and they know that’s not a good thing. Something has to be done to make sure that never happens again.” I could not let that one pass without a comment; I am quite sure that Mariotte has once again fallen victim to the fact that he surrounds himself with people who echo his own prejudices. Here is my response.
  • Marriotte makes an interesting statement by he claiming that “95% of the people in the world” know about Fukushima. That statement might be true about the people in the United States, where advertiser-supported television news programs covered the events with breathless hype for several months. I am pretty sure that you would have a difficult time finding anyone in China, central Africa, the Asian subcontinent, South America or the Middle East who can even pronounce Fukushima, much less know anything about GE Mark 1 containments. Most of them would not even know that they should be worried about radiation because they have never been taught to be afraid of something that they cannot smell, feel, taste, or hear especially when it occurs at levels that have no chance of making them sick within their expected lifetime. Mariotte, Gunter, Kamps, Katz and Bridenbaugh are all members of a vocal, but tiny group of people who have been carrying the water of the fossil fuel industry for decades by opposing nuclear energy, the only real competitor it has. They are victims of groupthink who believe that their neighbors in Takoma Park are representative of the whole world.
  • Just before making this comment, I voted in the unscientific poll associated with the article. 95% say that Oyster Creek should keep on powering New Jersey homes and businesses. They are not impressed by the Beyond Nuclear FUD; they like clean electricity.

204 new fuel rods turned out to be in the "spent" fuel pool at reactor 4.[29Oct11] - 0 views

  • Tepco has announced that there are 1,331 spent fuel rods in the pool of reactor 4. However, 10/14/2011, Nuclear and Industrial Safety Agency announced that the pool contained 204 units of new fuel rods as well. They assumed that once aftershock hits the pool and it’s damaged, the fuel rods get to 900 C, melting out of the zirconium cover in 2.3 hours later. As the zirconium alloy cover (Zircaloy) is destroyed, it emits hydrogen, which is likely to cause hydrogen explosion. The melted fuel rods are estimated to have reached 2,800 C and started to melt down some 7.7 hours later.
  • Currently Tepco is reinforcing the fuel pool, which is now exposed to outside because it lost the wall from the explosion. Today Hokkaido University stated that there is a possibility that another M9.0 hits north Japan again (soon? imminent?). They say they caught the same earthquake echo of 89.9MHz as what they caught before 311. According to their report, another M9.0 may hit from December to January, the epicenter may be from South Miyagi prefecture offshore to Ibaraki offshore, which is beside Fukushima plant.
  • Even apart from this report, it is rational to assume another major aftershock hits Fukushima plants anytime. Fukushima is still on the edge.

Obama's Gold - 94.6% Pure, Bomb Grade Plutonium [09Aug12] - 0 views

  •  President Obama asked Duke Power Corporation in the States to test run some plutonium fuel rods (MOX) in three of their reactors. The physicists said No; but, the head boss of Duke Power said “Yes.” Obama’s test run failed miserably.
  • As a result, the country very nearly lost the state of South Carolina. Those deadly  Plutonium cores were jerked out of those three big Duke Power reactors so fast it would make your head spin. Undaunted, unbowed and too ignorant to be afraid, the President of the United  States asked the President of a Japanese utility, the Tokyo Electric Power Company (TEPCO,) to run the “test” of the Plutonium fuel. Now, what are you going to do when the President of the US asks you for a favor? The test was slated immediately for the MOX fuel rods, of course. That is 21,000 lbs of 94.6% pure bomb grade Plutonium 239 (Pu 239) down blended and mixed with Uranium to form MOX 6% Pu 239 nuclear fuel rods.
  • Here’s what happened, perhaps as a result of President Obama’s political dabbling  in real life-or-death physics. This stuff gets real serious real fast.

  • Five hundred eighteen days into the continuous reactor meltdowns and global dispersion of reactor cores; it’s a direct choice for “Gruesome Death” made by the pro-nukers. The deed is done and cannot be reversed. MOX stands for Mixed Oxide Fuel. The very poisonous bomb grade Pu 239 is taken from Hydrogen Bombs and mixed with Uranium to form pellets for fuel rods for nuclear  reactors. The fuel rods are about five (5) meters or 16 ft long and as big around as a person’s thumb. Pu 239 is very hard for bomb makers to work with and tends to go off by itself, which makes for a really bad day. The manufacturing of Hydrogen Bombs is a very nasty business in any country. Putting extra Pu 239 in nuclear reactors to boil water for steam is insane. LETHAL DOSES How many Lethal Doses of radiation from radioactive particles are in our air just from Fukushima Daiichi’s trashed reactors? As of Jun 29, 2012 Dr. Paolo Scampa, a noted physicist stated: “… [about Fukushima reactors exploding]  … occasioning a prodigious explosion of radioactivity and radiotoxicity which over time, is several times the amount needed to kill by internal contamination the whole human race.” - Dr Paolo Scampa, PhD., Nuclear Physicist.

GE warns nuclear reactors could struggle in earthquake [03Oct11] - 2 views

  • A manufacturer of dozens of boiling water nuclear reactors in the country, including many on the East Coast, warned the Nuclear Regulatory Commission last year and reiterated last week that earthquakes could hinder its reactors from shutting down. GE Hitachi Nuclear Energy, which manufactured the boiling water reactors at Oyster Creek, Hope Creek and two plants in Pennsylvania, said that an earthquake could prevent rods that cool the reactor from being inserted. The rods cool the reactor down because they contain boron, which attracts neutrons. Without the rods, boron would be injected, a messier emergency solution.
  • "Earlier this week, they submitted the results of this evaluation they did and they found that friction that could result from an earthquake could impact the ability of control rods to insert all the way," said NRC spokesman Neil Sheehan Friday. "They serve a very important function and if there was a change of alignment in an earthquake and they could not insert all the way, it would be a problem." It’s not ideal to have a shutdown system fail at a moment of emergency, Sheehan said. "In a significant event like an earthquake, you would want to stop that from happening," Sheehan said, "because your safety systems could be challenged at the same time."
  • A spokesman for GE Hitachi Nuclear Energy said that when plants start up and shut down which amounts to about 1 percent of the time they run, added shaking from an earthquake could stop rods from easily sliding into the core. "There’s some friction," said spokesman Michael Tetuan. "They still insert, it’s just more friction than there would normally be." Last week’s NRC filing identified more than a dozen plants around the country that could be vulnerable, including Oyster Creek, Hope Creek and Limerick and Peach Bottom in Pennsylvania. Those plants were notified by GE Hitachi Nuclear Energy and recommended to participate in a surveillance program.

TEPCO Is Not Providing English Translation of Its Report to NISA on Emergency Cooling S... - 0 views

  • The Japanese government seems to be "instructing" TEPCO not to release certain information in English.TEPCO submitted the report to its regulatory agency Nuclear and Industrial Safety Agency (NISA) "on the measures to continue water injection into reactors of Units 1 to 3 at Fukushima Daiichi Nuclear Power Station" on August 3. It's in Japanese only, and it may or may not be translated into English.According to TEPCO:We have provided a Japanese press release version of the instruction document received from NISA. However, at this time we have reserved the right not to provide an English version due to potential misunderstandings that may arise from an inaccurate rendering of the original Japanese text. We may provide the English translation that NISA releases in our press releases. However, in principle we would advise you to visit the NISA website for timely and accurate information.(From TEPCO's English press release on August 3 explaining why they are releasing the information only in Japanese.)The 34-page Japanese report is here.
  • The report talks about the fuel inside the Reactor Pressure Vessels;It talks about the reactors as if they were sound;It states that zirconium will start to interact with water at a certain temperature (1,200 degrees Celsius).
  • Most likely, there is no fuel left inside the RPVs at Fukushima I Nuke Plant. Even if there is, it is not fuel any more but "corium" - fuel, control rods, instruments, whatever inside the RPV, melted together. TEPCO has already admitted that there are holes in the RPV, and holes in the Containment Vessels. There is no zirconium left because there is no cladding left.
  • ...3 more annotations...
  • nowhere in the report does the company say anything about melted fuel, broken reactors, water in the basements, or extremely high radiation at certain locations in the plant.But the report goes on to describe the elaborate backup pump system and power system as if what they are dealing with is normal (i.e. without cracks or holes at the bottom) reactors with intact fuel rods inside the RPVs with control rods safely deployed in a clean nuclear power plant, and all they need to worry is how they can continue the cooling; or as if the salt-encrusted molten mess of everything that was inside the RPV behaves just the same as normal fuel rods in a normal reactor.
  • Why was TEPCO asked by NISA to submit this report to begin with? So that the national government can begin the discussion with the local municipalities within the 20-kilometer radius evacuation zone for the return of the residents to their towns and villages. The discussion is to begin this month, and TEPCO's report will be used to reassure the residents that Fukushima I Nuke Plant is so stable now with the solid plans (to be approved by NISA, which no doubt will happen very soon) to cool the fuels in the reactors even in case of an emergency.
  • Remember the mayor of Naraha-machi, where Fukushima II Nuclear Power Plant is located? He wants TEPCO to restart the plant so that 5,000 jobs will return to the town. He also wanted to invite the government to build the final processing plant of spent nuclear fuels in his town. He would be the first one to highly approve of the report so that his town can continue to prosper with nuclear money.

  • Hydrogen accumulates in pipes at Fukushima’s No. 1 reactor, Asahi, September 24, 2011:
  • Hydrogen has accumulated to a level higher than previously thought in pipes connected to the No. 1 reactor containment vessel [...] The nitrogen injections are believed to have lowered the hydrogen concentration considerably, but some hydrogen, being lighter than nitrogen, may be accumulating near the top of the containment vessel without being driven out. [...] Nor could TEPCO measure how much hydrogen may have been generated in the containment vessel. [...] TEPCO said it is investigating the possibility that hydrogen has also accumulated in a similar manner at the plant’s No. 2 and No. 3 reactors. [...]
  • Where does TEPCO think the hydrogen is coming from?
  • ...1 more annotation...
  • TEPCO said most of the accumulated hydrogen was generated by a reaction under high temperatures between water vapor and the surface of nuclear fuel rods that were exposed after water was lost following the March 11 earthquake and tsunami. Even now, the damaged reactors may be generating small amounts of hydrogen as water decomposes through irradiation from the melted fuel rods.

  • TOKYO, Oct. 18 — Dr. Naoki Tsuji is testing the fingernails of Tokyo citizens checking for radioactive material, reports Mochizuki. The doctor published data that shows the detection of Uranium and Zirconium, which make up nuclear fuel rods. Cesium and Strontium were also measured. “He once tried the same test for Fukushima people but the result was terrifying,” Mochizuki writes, “Some of the materials went over the limit of the measurement, he said.” “Only tiny a part comes out to nail or urine,” he concludes, “We are becoming nuclear fuel rods.”

Worst Nuclear Disasters - Civilian [15Apr11] - 0 views

  • The top civilian nuclear disasters, ranked by International Nuclear and Radiological Event Scale. Worst Civilian Nuclear Disasters 1. Chernobyl, Soviet Union (now Ukraine) April 26, 1986 INES Rating: 7 (major impact on people and environment)
  • The worst nuclear disaster of all time resulted from a test of the reactor’s systems. A power surge while the safety systems were shut down resulted in the dreaded nuclear meltdown. Fuel elements ruptured and a violent explosion rocked the facility. Fuel rods meted and the graphite covering the reactor burned. Authorities reported that 56 have died as a direct result of the disaster—47 plant workers and nine children who died of thyroid disease. However, given the Soviet Union’s tendency to cover up unfavorable information, that number likely is low.  International Atomic Energy Agency reports estimate that the death toll may ultimately be as high as 4,000. The World Health Organization claims that it’s as high as 9,000. In addition to the deaths, 200,000 people had to be permanently relocated after the disaster. The area remains unsuitable for human habitation. 2. Fukushima, Japan March 11, 2011 INES Rating: 7 (major impact on people and environment) Following a 9.0 magnitude earthquake and tsunami, Japan’s Fukushima nuclear power facility suffered a series of ongoing equipment failures accompanied by the release of nuclear material into the air. The death toll for this currently is at two but is expected to rise and as of April 2011, the crisis still ongoing. A 12 mile evacuation area has been established around the plant.
  • 3. Kyshtym, Soviet Union Sept. 29, 1957 INES Rating: 6 (serious impact on people and environment) Poor construction is blamed for the September 1957 failure of this nuclear plant. Although there was no meltdown or nuclear explosion, a radioactive cloud escaped from the plant and spread for hundreds of miles. Soviet reports say that 10,000 people were evacuated, and 200 deaths were cause by cancer.
  • ...6 more annotations...
  • 4. Winscale Fire, Great Britain Oct. 10, 1957 INES Rating: 5 (accident with wider consequences) The uranium core of Britain’s first nuclear facility had been on fire for two days before maintenance workers noticed the rising temperatures. By that time, a radioactive cloud had already spread across the UK and Europe. Plant operators delayed further efforts in fighting the fire, fearing that pouring water on it would cause an explosion. Instead, they tried cooling fan and carbon dioxide. Finally, they applied water and on Oct. 12, the fire was out. British officials, worried about the political ramifications of this incident, suppressed information. One report, however, says that in the long run, as many as 240 may have died from accident related cancers. 5.
  • Three Mile Island, Pennsylvania, US March 28, 1979 INES Rating: 5 (accident with wider consequences) Failure of a pressure valve resulted in an overheating of the plant’s core and the release of 13 million curies of radioactive gases. A full meltdown was avoided when the plant’s designers and operators were able to stabilize the situation before contaminated water reached the fuel rods. A full investigation by the US Nuclear Regulatory Commission suggests that there were no deaths or injuries resulting from the incident.
  • 6. Golania, Brazil Sept, 1987 INES Rating: 5 (accident with wider consequences) Scavengers at an abandoned radiotherapy institute found a billiard ball sized capsule of radioactive cesium chloride, opened it and then sold it to a junkyard dealer. The deadly material was not identified for more than two year, during which time it had been handled by hundreds, including some who used the glittery blue material for face paint. Of the 130,000 tested, 250 were discovered to be contaminated and 20 required treatment for radiation sickness. Four died, including the two who originally found the capsule, the wife of the junkyard owner and a small girl who used the powder as face paint. 7. Lucens, Switzerland January 1, 1969 INES Rating: 5 (accident with wider consequences) When the coolant on a test reactor facility in a cave in Switzerland failed during startup, the system suffered a partial core meltdown and contaminated the cavern with radioactivity. The facility was sealed and later decontaminated. No known deaths or injuries.
  • 8. Chalk River, Canada INES Rating: 5 (accident with wider consequences) May 24, 1958 Inadequate cooling lead to a fuel rod fire, contaminating the plant and surrounding labs. 9. Tokaimura,Japan Sept. 30, 1999 INES Rating: 4 (accident with local consequences) The nuclear plant near Tokai had not been used for three years when a group of unqualified workers attempted to put more highly enriched uranium in a precipitation tank than was permitted. A critical reaction occurred and two of the workers eventually died of radiation exposure. Fifty six plant workers and 21 others also received high doses of radiation. Residents within a thousand feet of the plant were evacuated.
  • 10. National Reactor Testing Station, Idaho Falls, Idaho January 3, 1961 INES Rating: 4 (accident with local consequences) Improper withdrawal of a control rod led to a steam explosion and partial meltdown at this Army facility. Three operators were killed in what is the only known US nuclear facility accident with casualties. In addition to these, there have been a number of deadly medical radiotherapy accidents, many of which killed more people than the more commonly feared nuclear plant accidents: 17 fatalities – Instituto Oncologico Nacional of Panama, August 2000 -March 2001. patients receiving treatment for prostate cancer and cancer of the cervix receive lethal doses of radiation.[7][8] 13 fatalities – Radiotherapy accident in Costa Rica, 1996. 114 patients received an overdose of radiation from a Cobalt-60 source that was being used for radiotherapy.[9]

  • “I, along with many eminent scientists, are emphasizing the precarious situation of the fourth reactor that contains 1,535 nuclear fuel rods in the pool and is balanced on the second floor, outside of the reactor containment vessel. If the fuel rods spill onto the ground, disaster will ensue and force Tokyo and Yokohama to close, creating a gigantic evacuation zone. All scientists I have talked with say that if the structure collapses we will be in a situation well beyond where science has ever gone. The destiny of Japan will be changed and the disaster will certainly compromise the security of neighboring countries and the rest of the world in terms of health, migration and geopolitics. The Japanese government should immediately create an independent assessment team to determine the structural integrity of the spent fuel pool and its supporting structure. This is of the highest importance: the structure’s security is critical to the country’s future.” h/t Anonymous tip About Akio Matsumura Throughout his long career at the United Nations and other organizations he has brought together the unlikeliest of people: Arafat and Rabin, Chinese government officials and the Dalai Lama, and many more.

Impacts of the Fukushima Nuclear Power Plants on Marine Radioactivity - Environmental S... - 0 views

  • The impacts on the ocean of releases of radionuclides from the Fukushima Dai-ichi nuclear power plants remain unclear. However, information has been made public regarding the concentrations of radioactive isotopes of iodine and cesium in ocean water near the discharge point. These data allow us to draw some basic conclusions about the relative levels of radionuclides released which can be compared to prior ocean studies and be used to address dose consequences as discussed by Garnier-Laplace et al. in this journal.(1) The data show peak ocean discharges in early April, one month after the earthquake and a factor of 1000 decrease in the month following. Interestingly, the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments. By July, levels of 137Cs are still more than 10 000 times higher than levels measured in 2010 in the coastal waters off Japan. Although some radionuclides are significantly elevated, dose calculations suggest minimal impact on marine biota or humans due to direct exposure in surrounding ocean waters, though considerations for biological uptake and consumption of seafood are discussed and further study is warranted.
  • there was no large explosive release of core reactor material, so most of the isotopes reported to have spread thus far via atmospheric fallout are primarily the radioactive gases plus fission products such as cesium, which are volatilized at the high temperatures in the reactor core, or during explosions and fires. However, some nonvolatile activation products and fuel rod materials may have been released when the corrosive brines and acidic waters used to cool the reactors interacted with the ruptured fuel rods, carrying radioactive materials into the ground and ocean. The full magnitude of the release has not been well documented, nor is there data on many of the possible isotopes released, but we do have significant information on the concentration of several isotopes of Cs and I in the ocean near the release point which have been publically available since shortly after the accident started.
  • We present a comparison of selected data made publicly available from a Japanese company and agencies and compare these to prior published radionuclide concentrations in the oceans. The primary sources included TEPCO (Tokyo Electric Power Company), which reported data in regular press releases(3) and are compiled here (Supporting Information Table S1). These TEPCO data were obtained by initially sampling 500 mL surface ocean water from shore and direct counting on high-purity germanium gamma detectors for 15 min at laboratories at the Fukushima Dai-ni NPPs. They reported initially results for 131I (t1/2 = 8.02 days), 134Cs (t1/2 = 2.065 years) and 137Cs (t1/2 = 30.07 years). Data from MEXT (Ministry of Education, Culture, Sports, Science and Technology—Japan) were also released on a public Web site(4) and are based on similar direct counting methods. In general MEXT data were obtained by sampling 2000 mL seawater and direct counting on high-purity germanium gamma detectors for 1 h in a 2 L Marinelli beaker at laboratories in the Japan Atomic Energy Agency. The detection limit of 137Cs measurements are about 20 000 Bq m–3 for TEPCO data and 10 000 Bq m–3 for MEXT data, respectively. These measurements were conducted based on a guideline described by MEXT.(5) Both sources are considered reliable given the common activity ratios and prior studies and expertise evident by several Japanese groups involved in making these measurements. The purpose of these early monitoring activities was out of concern for immediate health effects, and thus were often reported relative to statutory limits adopted by Japanese authorities, and thus not in concentration units (reported as scaling factors above “normal”). Here we convert values from both sources to radionuclide activity units common to prior ocean studies of fallout in the ocean (Bq m–3) for ease of comparison to previously published data.

  • We focus on the most complete time-series records from the north and south discharge channels at the Dai-ichi NPPs, and two sites to the south that were not considered sources, namely the north Discharge channels at the Dai-ni NPPs about 10 km to the south and Iwasawa beach which is 16 km south of the Dai-ichi NPPs (Figure 1). The levels at the discharge point are exceedingly high, with a peak 137Cs 68 million Bq m–3 on April 6 (Figure 2). What are significant are not just the elevated concentrations, but the timing of peak release approximately one month after to the earthquake. This delayed release is presumably due to the complicated pattern of discharge of seawater and fresh water used to cool the reactors and spent fuel rods, interactions with groundwater, and intentional and unintentional releases of mixed radioactive material from the reactor facility.
  • the concentrations of Cs in sediments and biota near the NPPs may be quite large, and will continue to remain so for at least 30–100 years due to the longer half-life of 137Cs which is still detected in marine and lake sediments from 1960s fallout sources.
  • If the source at Fukushima had stopped abruptly and ocean mixing processes continued at the same rates, one would have expected that the 137Cs activities would have decreased an additional factor of 1000 from May to June but that was not observed. The break in slope in early May implies that a steady, albeit lower, source of 137Cs continues to discharge to the oceans at least through the end of July at this site. With reports of highly contaminated cooling waters at the NPPs and complete melt through of at least one of the reactors, this is not surprising. As we have no reason to expect a change in mixing rates of the ocean which would also impact this dilution rate, this change in slope of 137Cs in early May is clear evidence that the Dai-ichi NPPs remain a significant source of contamination to the coastal waters off Japan. There is currently no data that allow us to distinguish between several possible sources of continued releases, but these most likely include some combination of direct releases from the reactors or storage tanks, or indirect releases from groundwater beneath the reactors or coastal sediments, both of which are likely contaminated from the period of maximum releases
  • It is prudent to point out though what is meant by “significant” to both ocean waters and marine biota. With respect to prior concentrations in the waters off Japan, all of these values are elevated many orders of magnitude. 137Cs has been tracked quite extensively off Japan since the peak weapons testing fallout years in the early 1960s.(13) Levels in the region east of Japan have decreased from a few 10s of Bq m–3 in 1960 to 1.5 Bq m–3 on average in 2010 (Figure 2; second x-axis). The decrease in 137Cs over this 50 year record reflects both radioactive decay of 137Cs with a 30 year half-life and continued mixing in the global ocean of 137Cs to depth. These data are characteristic of other global water masses.(14) Typical ocean surface 137Cs activities range from <1 Bq m–3 in surface waters in the Southern Hemisphere, which are lower due to lower weapons testing inputs south of the equator, to >10–100 Bq m–3 in the Irish Sea, North Sea, Black Sea, and Baltic Seas, which are elevated due to local sources from the intentional discharges at the nuclear fuel reprocessing facilities at Sellafield in the UK and Cape de la Hague in France, as well as residual 137Cs from Chernobyl in the Baltic and Black Seas. Clearly then on this scale of significance, levels of 137Cs 30 km off Japan were some 3–4 orders of magnitude higher than existed prior to the NPP accidents at Fukushima.
  • Finally though, while the Dai-ichi NPP releases must be considered “significant” relative to prior sources off Japan, we should not assume that dose effects on humans or marine biota are necessarily harmful or even will be measurable. Garnier-Laplace et al.(1) report a dose reconstruction signal for the most impacted areas to wildlife on land and in the ocean. Like this study, they are relying on reported activities to calculate forest biota concentrations,

  • Translation of the Dec. 15, 2011 Nature Magazine article by former Prime Minister Yukio Hatoyama and legislator Tomoyuki Taira — both members of  by EX-SKF (Certain expressions may be off, as article was translated English to Japanese and then back to English) [Emphasis Added]: [Subheading:] Possibility of Nuclear Explosion We need to answer the question of what caused the series of explosions at Fukushima I Nuclear Power Plant. Initially, they were reported as hydrogen explosions [...] [T]his is not conclusive. Other possibilities exist, and they are nuclear explosions and gas explosions other than hydrogen gas. [...]
  • From two observed facts, we believe a nuclear explosion is more likely. First, several transuranic elements have been detected several tens of kilometers away from the plant. Second, the steel trusses in the upper part of the reactor building of Reactor 3 are twisted as if they had been melted.
  • According to the reports by the Ministry of Education and Science, curium-242 (242Cm) has been detected at a location 3 kilometers from the plant, and plutonium-238 (238Pu) has been detected at a location 45 kilometers from the plant. [...] 242Cm’s half life is short (about 163 days), and the deposition of 238Pu around the plant is far greater than normal, leading the Ministry of Education and Science to conclude these were emitted from Fukushima I Nuclear Power Plant. If that’s the case, pieces of broken spent nuclear fuel rods may have been scattered around the plant, and it is extremely dangerous.

  • These transuranic elements are not carried by the radioactive plume like much lighter cesium or iodine. Therefore, they must have been blown out by an extremely large force. [...] It is unlikely that a hydrogen explosion generated a high enough temperature that would melt steel
  • TEPCO initially announced that there was a white smoke from Reactor 3 explosion. However, the later investigation has revealed that the smoke was black, and a hydrogen explosion is not considered to generate such a black smoke. Our conclusion therefore is that it [explosion of Reactor 3] may have been a nuclear explosion.

Reactors 1 & 2 have HOLES up to 50 meters, clean up notes [9Dec11] - 0 views

  • expected to take more than 30 years to decommission crippled reactors at the Fukushima No. 1 Nuclear Power Plant, and workers tasked with the difficult mission would have to venture into "uncharted territory" filled with hundreds of metric tons of highly radioactive nuclear fuel,
  • After the expert committee of the Japan Atomic Energy Commission (JAEC) compiled a report on procedures to decommission the No. 1 to 4 reactors at the Fukushima No. 1 Nuclear Power Plant on Dec. 7, the actual work is expected to move into high gear after the turn of the year. As in the case of the 1979 Three Mile Island accident, the workers would try to remove melted nuclear fuel after shielding radiation with water, a technique called a "water tomb." But the work would have to be done in a "territory where humans have not stepped into before," said a senior official of Tokyo Electric Power Co. (TEPCO), the operator of the troubled Fukushima nuclear power station. The work is so difficult that it is expected to take more than 30 years to finish decommissioning the reactors.
  • Up to about 5,000 millisieverts per hour of radiation -- lethal levels -- have been detected in the reactor building of the No. 1 reactor.

  • The key part of the decommissioning work is to remove a total of 1,496 fuel rods from the No. 1 to 3 nuclear reactors and 3,108 fuel rods from nuclear fuel pools of the No. 1 to 4 reactors. The government and TEPCO are expected to start decommissioning the reactors early in the New Year after unveiling detailed plans around Dec. 16 that the nuclear plant has been brought under control by achieving a stable state called a ''cold shutdown.''
  • TEPCO said it would bring the nuclear plant under control by filling the reactors with water. But subsequent analysis of the accident suggested that the No. 1 and 2 reactors had holes of up to 50 square centimeters caused by hydrogen explosions and the like. In the work schedule announced in May, TEPCO said it had scrapped its plan to repair the containment vessels and suspended the work to fill them with water.
  • workers have been fighting an uphill battle to remove crumbled fuel. The reactors had been running without cooling water for a long time, and most of the fuel melted and apparently dropped into the containment vessel from the bottom of the pressure vessel at the No. 1 reactor
  • A single fuel rod contains about 170 kilograms of uranium, and a simple calculation suggests that about 254 tons of uranium in the reactors alone must be recovered. The distance between the upper lid and the bottom of a containment vessel is up to 35 meters. From that far away, the work has to be done to chop off and recover melted and crumbled fuel by using remote controlled cranes. Furthermore, the melted fuel is mixed with metal from fuel pellets and reactor parts.
  • "Because no one has seen the inside of the nuclear reactors, the timing of starting the work to recover nuclear fuel mentioned in the report is only a nonbinding target."
