Fukushima:
New International Report Shreds Japan's Carefully Constructed Fukushima Scenario
Needless to say, in the aftermath of the disaster, both TEPCO and the Japanese government were at pains to minimize the disaster’s consequences, hardly surprising given the country’s densely populated regions.
But now, an independent study has effectively demolished TEPCO and the Japanese government’s carefully constructed minimalist scenario. Mainichi news agency reported that France’s l’Institut de Radioprotection et de Surete Nucleaire (Institute for Radiological Protection and Nuclear Safety, or IRSN) has issued a recent report stating that the amount of radioactive cesium-137 that entered the Pacific after 11 March was probably nearly 30 times the amount stated by Tokyo Electric Power Co. in May.
Japan lawmaker drinks water from Fukushima plant
A Japanese lawmaker has drunk a glass of water taken from a radioactive puddle inside a reactor building at the stricken Fukushima nuclear plant in a bid to prove decontamination efforts are working.
Television footage showed a visibly nervous Yasuhiro Sonoda gulping down water that he said had been decontaminated after being scooped up from inside the plant.
“Just drinking (decontaminated water) doesn’t mean safety has been confirmed, I know that,” Sonoda told reporters. “Presenting data to the public is the best way.”
Webmaster's Commentary:
One would hope that this man had a will fully in place before he did this.

Radioactive Silver-110m detected at over 10,000 Bq/m² outside 30km evacuation zone (MAP)
Oct. 31 — “The Ministry of Education and Science announced on October 31 the ‘result’ of the survey they did in June. Much like announcing the result in July of the survey they did in March about radioactive fallout in Tohoku and Kanto, where radioactive iodine, cesium tellurium and silver were found in abundance in Tokyo,” reports EX-SKF.
See maps from the Ministry’s announcement on October 31 here: http://radioactivity.mext.go.jp/ja/distribution_map_around_FukushimaNPP/0002/5600_103120.pdf
The half life of Silver is about 250 days.
“Silver-110m probably came from melted control rods, and went all the way to Tokyo,” notes EX-SKF.

Mainichi has a report featuring radiochemical expert Michiaki Furukawa, professor emeritus at Nagoya University:
- He says that some reports about plutonium have been misleading.
- “When the disaster first happened, there were media reports saying ‘plutonium won’t make it far because it’s a large and heavy element,’ but no one who’s done serious research in environmental radioactivity would say such a thing.”
- “At the very least, plutonium-238 had to have come from the explosions (at the plant). The plutonium that had heated up inside the reactors turned into fine particles when it came in contact with water, and was dispersed with the water vapor released in the explosions.
Yet, Furukawa says, “Since the plutonium takes the form of particles — unlike the gaseous radioactive iodine — it probably didn’t fly 100 kilometers.”
Some previous reports, however, appear to refute Furakawa’s claim:
- Takashi: Plutonium evaporated and spread around as gas after Fukushima meltdowns
- "Very high concentrations" of hot particles in Pacific NW during April, May -- Includes plutonium and americium (AUDIO)
- Nuclear expert says Americium has been found in New England -- Element even heavier than Uranium (VIDEO)
- Neutron ray measured in Tokyo -- Uranium-235 found in Chiba -- Can't be detected by most geiger counters (PHOTO & VIDEO)
- Uranium-234 detected in Hawaii, Southern California, and Seattle
Also in the Mainichi article, Hiroshi Ishihara, who heads the Medical Treatment for the High Dose Exposure Research Group at the National Institute of Radiological Sciences (NIRS) in Chiba, speaks about plutonium:]
- He says that “inhaling 910 becquerels or more of plutonium-238 is believed to slightly raise the possibility of cancer.”
- He adds that this will equal a cumulative radiation exposure of 100 millisieverts in 50 years… just from the plutonium-238.
- “Even if one were to have inhaled plutonium soon after the explosions took place, it’s hard to think that the amount was enough to have any effects health-wise.”
Even the Nuclear Safety Commission of Japan disagrees, saying “We do not take the position that plutonium is safe in amounts up to 910 becquerels.”

Truth & Consequences: A guide to the triple melt-throughs at Fukushima (VIDEOS)
Oct. 30 — “Tepco announced they started building the impermeable wall (SOURCE: Sankei, MSN) on the sea side of reactor 1~4 on 10/28/2011. They say it takes 2 years to build,” according to Fukushima Diary.
In a recent press release TEPCO said, “On October 28, we started installation of the water proof wall at the sea side, in front of the existing shore protection, Units 1-4, in order to contain marine pollution by underground water.”
According to the 2006 film The Battle of Chernobyl, which appeared on the Discovery Channel, Soviet officials were extremely concerned — not only with contamination of the water supply — but that a massive explosion would occur when the melted nuclear fuel came into contact with water underneath the reactors.
This explosion “would have wiped out half of Europe,” an official interviewed for the film says — a fact governments around the world kept secret for decades. Minsk, 320 km away, would have been razed and Europe rendered uninhabitable. Tokyo, the world’s most populated city, is only 250 km from the Fukushima meltdowns.
Here is a 5-minute video of relevant clips from ‘The Battle of Chernobyl’:
The Japanese government made a video simulating what melted fuel burning through the containment looks like:

Tokyo U. Nuke Expert: “Possible that nuclear reaction is STILL taking place inside the reactor” -WSJ
TOKYO, Nov. 1 — According to Satoru Tanaka, a professor of nuclear engineering at Tokyo University, “It is possible that nuclear reaction is still taking place inside the reactor,” reports the Wall Street Journal.
The Journal article also includes statements by a Japan gov’t spokesman at NISA:
- Xenon-133 has a short half-life of five days, and Xenon-135 just nine hours, meaning that they were released only recently
- If Xenon was indeed found, “it would indicate that neutrons still exist inside the reactor, causing fissile reaction”
- But he stressed that this by no means suggests that the fuel is in a condition of criticality
Read More: Japan Says Xenon May Have Been Released at Plant
Nov. 1 — “Xenon was detected in the order of 10^-5 (ten to the power of minus 5) per cubic centimeter, says TEPCO’s Matsumoto in the press conference that is on-going right now in Japan,” reports EX-SKF, “It is significant enough to conclude it is not from March.”
“Matsumoto does think a localized, small-scale, and/or temporary nuclear fission may have occurred in Reactor 2,” the article continues.
Some possibilities put forth by TEPCO to explain the detection of xenon-133 and -135 include:
- “Neutrons that exist inside the reactor hitting uranium or plutonium”
- “Curium-244, -242, causing ‘spontaneous fission’”
Click for full-size TEPCO handout
The TEPCO spokesman said, “It would be difficult to deny that the same thing is not happening in Reactors 1 and 3,” according to EX-SKF.
Nov. 1 — EX-SKF is again kind enough to publish a translation, this time of an NHK report from 6:38 am this morning in Japan:
“Xenon has been detected in the Containment Vessel of Reactor 2 at Fukushima I Nuclear Power Plant. Xenon is created when there is nuclear fission.” [...]
“The analysis done on November 1 found xenon-133 and xenon-135, which are created when uranium-235 undergoes nuclear fission.”
“Xenon-133′s half life is 5 days. TEPCO says it could not rule out the possibility of nuclear chain reaction happening again, so the company poured water with boric acid into the reactor to suppress the nuclear chain reaction for one hour starting 3AM [on November 2].” [...]
“[TEPCO says that] if the nuclear chain reaction is happening, it is small-scale.”
“[NISA says that] it is hard to imagine the fuel is melting again. But the Agency says it will monitor the situation to see if xenon continues to be detected after pouring in the water with boric acid.”
EX-SKF also reminds us of the recent report of hydrogen gas concentration rising in Reactor No. 2.
Japan gov’t says 170 uSv/h at Tokyo supermarket from radium… AND BOTTLES (Again)
TOKYO, Nov. 1 — According to NHK, the Japan government says the extremely high radiation dose of 170 microsieverts per hour detected at a supermarket in the residential Tokyo neighborhood of Setagaya is “most likely” caused by radium 226.
Government scientists detected substances “related” to radium 226 at a depth of about 30 centimeters.
Sound familiar? Japan officials has similar things to say about the other extreme hotspot in Setagaya found several weeks ago. Reports at the time indicated that not everyone was convinced.
And maybe this revelation about the most recent hotspot will also ring a bell:
“The ministry says that they also found a bottle of chemical at the same site, about 40 centimeters below surface, and detected radiation of 40 microsieverts per hour nearby. The ministry plans to investigate the link between the bottle and the radiation,” reported NHK.
Contaminated bottles were also put forth as the culprit in the first Setagaya hotspot: Recent reports have linked the radiation to bottles of paint stored underneath the floor of a nearby home. (BBC, Bloomberg)
About the radium-filled bottles at the first hotspot, The Japan Times said, “It remains unclear whether the two radiation finds are linked.”
Hopefully, The Times won’t take too long before publishing their take on radium/bottle today’s news.
Headline: Cesium in pollen not viewed as health risk
Source: The Japan Times Online, By KAZUAKI NAGATA
Date: Nov. 1, 2011
Excerpts
“In June, the education and science ministry studied cedar leaves in the town of Kawamata, located about 45 km from the Fukushima No. 1 nuclear plant, and determined the cesium-134 and -137 levels ranged from 54,300 to 177,600 becquerels per kilogram.”
“The Forestry Agency used those results to estimate the radiation exposure from pollen grains. If the level of contamination was 177,600 becquerels per kilogram and the concentration of pollen grains — a gauge of pollen density that shows how many grains are floating in 1 cu. meter of air — was 2,207, the exposure would be equal to 0.000132 microsievert per hour.”
“On average, the concentration of pollen grains is 89 in the Kanto region, but the calculation used 2,207, the highest figure recorded in the region in the past eight years.”
“Hiroki Matsumoto, an official at the agency, said cedar pollen is so light it can fly hundreds of kilometers, meaning it can reach densely populated Tokyo and surrounding areas.”
“Weather conditions could bring pollen from Fukushima, he added.”

UPDATE: See also TEPCO: If nuclear chain reaction is happening, it is 'small-scale' -- NHK: Xenon created when there is nuclear fission of uranium-235
Nov. 1 — “Fission restarted at reactor 2,” reports Fukushima Diary.
Citing Jiji Press and NHK (Japanese-only) as sources, Mochizuki says, “Xenon133 and 135 are measured at reactor 2.”
This radioactive xenon is a daughter product of Uranium-235. Xe-133 has a half life of 5.2 days, while Xe-135 has a half life of 9 hours.
“It proves the nuclear fuel is fissioning at reactor 2 still,” concludes Mochizuki.
Also, Tepco has starting injecting boric acid into the reactor.
Here is the Babelfish Translation of the Jiji Press report from Nov. 2, 2 in machine reactor with possibility of boracic acid water fill = fission – Fukushima:
“Tokyo Electric Power Fukushima 1st nuclear accidents, the same company 2 day early dawn, 2 when the gas which from the containment vessel of the machine was picked on the 1st was analyzed, announced that there is a possibility the xenon 133 whose half-life is short and the same 135 being detected.”
“Assuming that the fission reaction of the melted fuel cannot be denied, 2nd 2:50 AM you used the chilled water fill line to the reactor from around, started the fill of the boracic acid water. 2 abnormal fluctuation because it is not, has managed for sense in the radiation dose of the monitoring post of temperature and pressure and around of the reactor of the machine.”
Here is the Babelfish Translation of the November 2 NHK report, When 2 the fission reaction reactor pouring water:
“When 2 from the Containment Vessel of the machine of the Tokyo Electric Power Fukushima first nuclear power plant, the fission reaction occurred, the xenon of the radioactive substance which is produced was detected, Tokyo Electric Power assuming that it cannot deny the possibility the fission reaction occurring filled the boracic acid water which holds down the fission reaction to the reactor.
“2 in the machine of the Fukushima first nuclear plant, last month it sucks out the vapor from midst of the Containment Vessel from 28th, having begun driving the device which removes the radioactive substance through the filter, measuring the type and density of radioactive substance near the exit of this device, it analyzes.
“As a result, with the analysis which does on the 1st, uranium 235 of the nuclear fuel fissioning, it means that xenon 133 of the radioactive substance which is produced and xenon 135 was detected.
“As for xenon 133 because the half-life when the quantity of the radioactive substance becomes half 5 days it is short, as for Tokyo Electric Power, assuming that again it cannot deny the possibility the fission reaction occurring, it filled the boracic acid water which holds down the fission reaction to the reactor 3 o’clock in the morning from before over 1 hours.
“According to Tokyo Electric Power, temperature and pressure of the reactor, as for big fluctuation because it is not, the fission reaction occurring, as for scale we have assumed in value of the monitoring post which measures the radiation dose around the site to that it is small.
“According to the atomic energy safety preservation institute of the economic industrial ministry, we have assumed that from the fact that density of the xenon which is detected is low, is not change in temperature and the like of the reactor, the fuel melts for the present again with is difficult to think, but whether or not after filling the boracic acid water, detection of xenon does not continue, we have assumed that circumstance is ascertained.”
JEC writes in with a link to an Asahi report (Translation via Babelfish), Fukushima first nuclear plant 2 possibility boracic acid water of machine and fission fill
“The Tokyo Electric Power Fukushima first nuclear plant 2 with the machine, the radioactive xenon whose half-life is short from the vapor inside the containment vessel was detected very small amount, from the fact that it is the possibility the fission reaction occurring, Tokyo Electric Power Company 2nd 2:50 AM around, began the fill of the boracic acid water which is the character which holds down fission.”
“As for fluctuation you call to the measurable quantity of the monitoring post which measures the radiation dose inside the nuclear site that it is not seen.”

TOKYO, Nov. 1 — EX-SKF on Setagaya, Tokyo’s High Radiation Supermarket: It’s Radium Again, Emitting 40 Millisieverts/Hr Radiation:
“According to the Ministry of Education and Science, a glass bottle was found 40 centimeters below the surface, which was emitting 40 millisievert/hour radiation. Radium-226 is suspected.”
“(How many more radium-226 bottles are there buried in Setagaya-ku?)”
Excerpts from EX-SKF’s translation of a Nov. 1 report from Yomiuri:
“At 40 centimeters below the ground surface, 40 millisieverts (or 40,000 microsievert) per hour radiation was measured, according to the Ministry. 40 millisievert is 40 times the annual radiation exposure limit for the general public.”
“According to the Ministry of Education, there was a glass bottle at 40 centimeter below the surface, and the radiation on the spot was 40 millisieverts/hour. The radiation on the ground surface there was 1 millisievert/hour. The work is proceeding very cautiously because the radiation level is extremely high. The bottle will be removed on November 2 or after.”
Screenshot of Google Translation for the Yomiuri article which mentions 40 millisieverts explicitly several times, converts that to 40,000 microsieverts, and says it is 40 times the 1 millisievert yearly ‘limit’:
Though NHK’s report on this matter says 40 microsieverts per hour, an English-language article from the Japan Times says, “The Setagaya Ward Office said the removal work could take as long as two weeks.” The Times’ makes no mention of a specific radiation dose measurement.
Nov. 2 — “There was a “100-Fold Increase in Krypton-85 from November 1,” reports EX-SKF.
From TEPCO’s Nov. 2 press materials:
Comparison of testing done on Nov. 1 and Nov. 2 in Reactor No. 2′s primary containment vessel
Krypton-85 went from .0036 Bq/cm³ (3.6 x 10-³) to 0.53 Bq/cm³ (5.3 x 10-¹).
That is an increase of over 14,000% in one day.
One might wonder why Krypton-85 was chosen as an isotope to test for, when its half life is over 10 years.
Kr-85 on Nov. 1 @ .0036 Bq/cm³
Kr-85 on Nov. 2 @ 0.53 Bq/cm³
This would seem to make it not the best indicator of recent criticality because it lasts much longer than, for example, xenon-133, xenon-135 and iodine-131.
However, according to a study published in the Journal of Environmental Radioactivity, “Krypton-85 is the best indicator for clandestine plutonium separations” when conducting wide-area atmospheric monitoring.
Also, EX-SKF writes, “According to wiki, ‘About three atoms of krypton-85 are produced for every 1000 fissions (i.e. it has a fission yield of 0.3%)’. It sure looks like a nuclear chain reaction happening, i.e. re-criticality, the possibility of which TEPCO’s Matsumoto has already admitted.”
Here is an excerpt Debito Arudou‘s latest piece for the Japan Times:
“Regardless, the awful truth is: ‘We Japanese don’t lie. We just don’t tell the truth.’”
“This is not sustainable. Post-Fukushima Japan must realize that public acceptance of lying got us into this radioactive mess in the first place.”
“For radiation has no media cycle. It lingers and poisons the land and food chain. Statistics may be obfuscated or suppressed as usual. But radiation’s half-life is longer than the typical attention span or sustainable degree of public outrage.”
“As the public — possibly worldwide — sickens over time, the truth will leak out.”
Nov. 2 — Unexpected bursts of fission “threaten to increase the amount of dangerous radioactive elements leaking from the complex and complicate cleanup efforts, raising startling questions about how much remains uncertain at the plant” in Fukushima, reports the New York Times.
“The three reactors — together with spent fuel rods stored at a fourth damaged reactor — have been leaking radioactive material since the initial disaster, and new episodes of fission would only increase their dangers.”
According to Hiroaki Koide, assistant professor at Kyoto University’s Research Reactor Institute, “Re-criticality would produce more harmful radioactive material, and because the reactors are damaged, there would be a danger of a leak.”
Nov. 2 — “Nuclear workers at the crippled Fukushima power plant raced to inject boric acid into the plant’s No. 2 reactor early Wednesday after telltale radioactive elements were detected there, and the plant’s owner admitted for the first time that fuel deep inside three stricken plants was probably continuing to experience bursts of fission,” reads the opening sentence of today’s New York Times report by Hiroko Tabuchi (Emphasis Added).
According to The Times, a Tepco spokesman said, “Detailed measurements had not yet been taken at two other severely damaged reactors on the Fukushima site, but acknowledged the possibility of episodes of fission there too.”
“Some nuclear experts have debated for months whether nuclear reactions might be continuing, either in the fuel inside the reactors, or in the spent fuel pools at the plant. They have pointed, for example, to the continued reports of short-lived iodine in the spent fuel pool at Reactor No. 3,” notes the article.
Here is a selection of reports from the last two months about the detection of isotopes that indicate a nuclear reaction has occurred:
- Recriticality? Iodine-131 detected in rice samples from late October
- Recriticality? Major Japan paper reports on detection of iodine-131 in Tokyo, Kawasaki
- "Recriticality may be happening continuously" -- Iodine-131 detected in Nagasaki, Miyagi (CHARTS)
- Krypton-85 and xenon-131m detected in samples from Reactor No. 2 -- Xenon-131m has half life of only 12 days
- I think there was a recriticality where melted fuel started a chain reaction again: UCSD researcher -- Largest amount of radioactive materials released since April
- "Fukushima in recriticality"? -- Iodine-131 detected in 4 locations: Tokyo, Iwate, Nagano, Niigata (CHARTS)
Nov. 2 — “Some of the fuel has escaped the vessel, experts believe, and is in spaces underneath, where there is no way to use control rods to interrupt the flow of neutrons,” reports the New York Times.
The Times reporters interviewed Hiroaki Koide, assistant professor at Kyoto University’s Research Reactor Institute:
- “Mr. Koide holds that the nuclear fuel at the three reactors probably melted through containments and into the ground, raising the possibility of contaminated groundwater.”
- “If much of the fuel was indeed in the ground early in the crisis, the “feed and bleed” strategy [...] would not have done anything to reduce danger from fuel already in the soil…”
According to the Times, “Tokyo Electric does not deny the possibility that the fuel may have burrowed into the ground, but its officials say that ‘most’ of the fuel likely remains within the reactor, albeit slumped at the bottom in a molten mass.”
The Times reported on another interview about the location of the fuel, this one with “a former nuclear engineer with three decades of experience at a major engineering firm… who has worked at all three nuclear power complexes operated by Tokyo Electric” who spoke on the condition of anonymity:
- “His main concern was that officials could not pinpoint the exact location of the nuclear fuel — which would greatly complicate the cleanup.”
- “He said that tiny fuel pellets could have been carried to different parts of the plant, like the spaces under the reactor during attempts to vent them in the early days. That would explain several cases of lethally high radiation readings found outside the reactor cores.”
- “If the fuel has been dispersed more widely, then we are far from any stable shutdown.”

Nov. 3, 8:30 pm ET (Emphasis Added) — A report published at 8:30 pm ET by the Japan Times calls on Tepco and the Japan gov’t to “find out true reactor conditions” at Fukushima.
Tepco announced Wednesday that, according to the Times, “There is the possibility that criticality, a sustained nuclear chain reaction, had occurred ‘temporarily’ and ‘locally’ in the No. 2 reactor.”
During it’s testing, Tepco has detected xenon-133 and -135, “Products of uranium or plutonium fission.”
The half life of xenon-135 is about 9 hours, therefore, “Criticality is very likely to have occurred just before the gases were analyzed,” reports the Times.
“Clearly the reactor has not yet been stabilized,” and, according to the Times, “The fact that Tepco cannot deny the possibility of criticality irrespective of its scale is a grave situation.”
And the article notes, “Conditions are similar in the Nos. 1, 2 and 3 reactors.”
Now is the time to get “serious” writes The Times:
- “Tepco should make serious efforts to accurately grasp the conditions of nuclear fuel inside the reactors.”
- “Tepco and the Nuclear and Industrial Safety Agency should take a serious view of the fact that radioactive xenon pointing to criticality was detected from the No. 2 reactor. What happened in it can happen in the Nos. 1 and 3 reactors.”
Nov. 3 — Regarding the detection of xenon, TEPCO has “played down the find, saying there was no evidence of a ‘criticality’ in the reactor,” reports the UK’s Channel 4 News, “Now there are concerns that the situation is worse than the authorities believed.”
According to the report, “Nuclear expert John Large* told Channel 4 News that any evidence of fission was a ‘concern’.”
“It shows there are still considerable problems. It’s concerning because it shows they are not in total control of the nuclear processes in the plant – and even a small amount of fission is a concern because it can become a large amount of fission,” said Large.
*Large was invited by the UK gov’t to join the Technical Advisory Panel working on assessing the implications of Fukushima for the country’s nuclear industry.
Nov. 3 — “South Korea’s Institute of Nuclear Safety says it has discovered a patch of pavement in Seoul is emitting radiation at levels 10 times higher than normal,” according to Voice of America News.
“The institute says the pavement is emitting radiation from cesium-137 at 10 times the normal background level,” said the report. [...]
Other Facts:
- Found on Wednesday
- Located in Seoul’s Wolgye-dong neighborhood.
- Researchers say they are not yet able to determine why a significantly higher level of radioactive cesium has turned up.
- INS says a more precise reading will be released in 3-5 days after further evaluation

Fukushima xenon from spontaneous decay, World Nuclear News*, November 3, 2011 at 10:30 am ET:
Excerpt
“Tepco said it considered the source of the xenon to be spontaneous fission on those grounds that it had injected boric acid to the reactor vessel to reduce the likelihood of chain fission reactions but was still able to detect xenon.”
*World Nuclear News “is supported administratively and with technical advice by the World Nuclear Association”; The WNA is “supporting a fast-globalizing nuclear industry”
Nov. 3 — TEPCO said on Thursday that the xenon-135 detected at Reactor No. 2 “was the result of the spontaneous nuclear fission of radioactive curium-242 and -244,” reports NHK.
“The amount of xenon-135 detected almost matched the amount that would have been produced if the radioactive curium in the fuel had undergone spontaneous fission.”

Nov. 3 — Radioactive materials have been detected in Tokyo Bay, NHK reported yesterday:
- “Waste water discharged into Tokyo Bay from a cement plant has been found to contain radioactive cesium at much higher levels than the government-set limit for disposal.”
- “It found radioactive cesium at levels of 1,103 becquerels per kilogram, and 1,054 becquerels per kilogram respectively.”
- “The levels are 14 to 15 times higher than the limit set by the country’s Nuclear Safety Commission.”

On a related note, Tokyo has started disposing of 500,000 tons of rubble from the disaster area, reports NHK:
- “Freight trains brought the rubble from Iwate Prefecture to a facility in Tokyo.”
- “Officials conducting random radiation checks on the rubble said a sample had a reading below the maximum allowable level set by Tokyo at 0.01 microsieverts per hour.”
- “The rubble will be disposed of on reclaimed land in Tokyo Bay after some of it is burned.”

- “Xenon was detected in the containment vessel of the plant’s No. 2 reactor, and the finding was confirmed by the semi-governmental Japan Atomic Energy Agency”
- “The finding suggests that nuclear fission is occurring in the reactor”
- “The government and TEPCO need to find out why the fission has occurred and take appropriate responses”
- “The possibility that it might reach criticality has surely caused anxiety to the public”
- “At least one expert says it would be no surprise if nuclear fission has been occurring since well before these latest findings”
- “The gas inside the containment vessels of the Fukushima plant’s No. 1 and 3 reactors has not yet been analyzed”
- “Officials should consider equipment that can detect neutrons, as they can be used as a direct indicator of whether criticality has occurred”
- “The discovery of xenon in the No. 2 reactor’s containment vessel suggests nuclear fission is occurring even though the temperature at the bottom of the pressure vessel is thought to be below 100 degrees Celsius — It raises questions as to whether such a reactor can be considered stable, even if it is under that temperature threshold”
- “The conditions and locations of melted fuel in the plant’s No. 1 to 3 reactors as well as the details of the damage to the reactors remain unclear”
Find out true reactor conditions
Tokyo Electric Power Co. announced Wednesday that there is the possibility that criticality, a sustained nuclear chain reaction, had occurred "temporarily" and "locally" in the No. 2 reactor of the stricken Fukushima No. 1 nuclear power plant. It detected radioactive xenon-133 and xenon-135, products of uranium or plutonium fission, in gases collected Tuesday from the reactor.
Because the half life of xenon-133 is 5.25 days and that of xeon-135 is 9.14 hours, criticality is very likely to have occurred just before the gases were analyzed.
Although more than seven months have passed since the start of the nuclear fiasco, clearly the reactor has not yet been stabilized. Tepco's plan to achieve "cold shutdown" of the Nos. 1, 2 and 3 reactors by the end of this year may face difficulty.

Nov. 3 — “A rare type of radioactive decay, not a renewed chain reaction, appears to have produced the radioactive xenon gas,” reports CNN.
According to the report, on Thursday Tepco said “it believed the gases were produced by ‘spontaneous fission’ of uranium, since the shorter-lived isotope persisted after the use of boric acid”.
Gary Was, a nuclear engineering professor at the University of Michigan, told CNN that ‘spontaneous’ fission occurs when an element like uranium splits on its own, though it’s an “improbable phenomenon”.
Professor Was noted that the detection of xenon happened less than a week after Japan began taking new gas samples from the reactors.
It is highly coincidental that so soon after the sampling began an “improbable phenomenon” like ‘spontaneous’ fission would occur.
Unfortunately, no report has mentioned the massive increase in Krypton-85 in the same location as the small rise in xenon. Krypton-85 is used to detect plutonium fission.

Or
2) “An explosive criticality which occurred 60 hours before the measurements”
“What these results confirm is that there is on-going fission occurring at the site,” concludes Busby.

How dangerous are the horror Fukushima really is?
Edmund Lengfelder
Tokyo – After an uncontrolled nuclear fission a few days ago, warns the German radiation expert Professor Edmund Lengfelder from further nuclear explosion in Fukushima.
“There is a spontaneous fission – because anything can happen, even if one says, it is not likely. But what is to be kept of statements about probabilities, we have on 11 Seen in March, “said the founder of the Society for Radiological Protection. [...]
In plain language: [xenon] can not originate from the meltdown of the March. In Fukushima, it comes back to uncontrolled meltdowns.
Therefore Lengfelder compares the horror with a nuclear bomb in the mini-scale attacks and the operator: “Tepco is even further than previously claimed, away to get things under control.”
*UPDATE* translated DPA article via BreadAndButter:
In view of reports of an uncontrolled nuclear fission reactor accident in Japan’s Fukushima Munich Radiation expert warns of Prof. Edmund Lengfelder of the possibility of a nuclear explosion.
It would be “a kind of mini-nuclear bomb in the scale,” said Lengfelder the dpa news agency. “The probability, however I can not estimate at all,” said radiation expert. Because nobody knows how much enriched uranium as coalesced into how the derelict nuclear power plant units. It had been found, the radioisotopes 133 and 135 of the xenon gas.
Because these are products of nuclear fission, which have only a half-life of about five days and nine hours, they could not come from the time of the accident in March , “There is there a spontaneous fission – can happen because everything, even if they say, it is not likely. But what is to be kept of statements about probabilities, we have on 11 March seen, Lengfelder said.
At that time had seriously damaged a strength in this unexpected earthquake and a tsunami and the nuclear power plant caused the meltdown. In a functioning reactor is maintained in the words of experts, the chain reaction by control rods under control. “But it is this control in a meltdown so no longer.”
Lengfelder had after the meltdown at Chernobyl 25 years ago the Society for Radiological Protection and the Munich-based Otto Hug Radiation Institute. He cared for people with thyroid cancer today in the former Soviet disaster area. The radiation expert also criticized the crisis management in Japan. “For me, it is also inhumane, that in such a wealthy country like Japan, people still live in the gyms. That there was not even on the Soviets “The evacuation after Chernobyl have worked much better.”

* “The Fukushima nuclear accident dispersed airborne dusts that are contaminated with radioactive particles. When inhaled or ingested, these particles can have negative effects on human health that are different from those caused by exposure to external or uniform radiation fields.”
* “A field sampling effort was undertaken to characterize the form and concentration of radionuclides in the air and in environmental media which can accumulate fallout. Samples included settled dusts, surface wipes, used filter masks, used air filters, dusty footwear, and surface soils.”

- “There were plans for new reactors at more than 30 different sites”
- “Today there are only five”
- “Even those planned reactors might disappear”

- “Cause of this decline is [...] simple economics”
- It’s “not renewed concerns about safety”
- “Or even that old red herring, waste disposal”
- “Other technologies, particularly natural gas, offer much cheaper power than nuclear both today and in the foreseeable future”
- “In reality, credit markets assign a significant risk premium to nuclear power, bringing its total levelized cost of electricity to 8.4 cents/kWh, nearly twice the cost of natural gas power”
- “Nuclear power is down, but not out”

The only mention of the word Fukushima is the title and opening sentence.
Four days after the 9.0 earthquake the author of this column wrote a piece titled, What happened at the Fukushima reactor? Here’s an excerpt:
“[A]n explosion on Saturday at 15:30 [...] destroyed the outer containment building (the drywall “fourth” layer). The explosion itself was not a serious risk” [...]
“What is the take-away?
“From the information we have, we can draw a conclusion anywhere between “the reactor is undamaged and being cooled” to “the reactor cladding and/or fuel has been partially damaged, but the damage is contained and the reactor is being cooled.”
“The question that should be asked now is whether the reactor has any future value as an electricity-producing asset.
“The widely-hyped possibility of some Chernobyl-like event is inconceivable without a new, catastrophic disaster.
“Coolant flow has been re-established and the public is in no danger.
“Given the magnitude of the precipitating event — a 9.0 earthquake — and the vast property damage it caused, the events at Fukushima are not a serious reason to re-evaluate our own nuclear policy in the United States.”
