Japan Times, Sept 19, 2014: Tainted water problems still plague Fukushima, despite some positive signs — More than three years since [3/11] the Fukushima No. 1 power plant is still bleeding tons of toxic radioactive water into the Pacific Ocean… [It’s] developed into a wider problem that is stoking public concern… [Tepco] is still trying to find a way to deal with the plant’s utility trenches, which are filled with highly contaminated water. The trenches, which run beneath the plant, were built to house cables and pipes… installed to bring in seawater for cooling purposes… Leaving the tainted water in the trenches is risky. For instance, if another major quake hits and damages the trenches, the toxic water will escape and contaminate the groundwater. Tepco said the trenches… can’t be drained until the leaks from the buildings are plugged… Continue reading »

Officials at the plant noticed late in the afternoon that the emergency cooling system was not working, but Yoshida wasn’t informed until late that night and the reactors had already started melting down. Yoshida: “I’m very regretful about this, we failed to establish a system to receive warnings from employees on time.” Continue reading »
- Plutonium detected underground near Fukushima reactor — Test results not revealed publicly for almost a year after sampling date — Officials plan to pump up groundwater from same well it was found in and dump it into Pacific Ocean (PHOTO) (ENENews, Aug 13, 2014):
Kyodo News, Aug 11, 2014: Plan filed to build toxic water dumping facility at Fukushima plant [...] TEPCO plans to conduct performance tests next week [...] using water it will start pumping up on a trial basis Tuesday [...] Radioactive substances [...] have been detected in some water samples from the wells. TEPCO says it aims to clean the water to a level that would do no harm to the environment, but tritium will remain untreated as no water treatment facility at the plant is capable of removing the substance.
South China Morning Post, Aug 13, 2014: Tepco began pumping up groundwater from beneath the Fukushima plant [and it] intends to test the radioactivity of the water and examine whether levels can be reduced. [...] fishermen are expected to voice opposition. The government is likely to step in to provide additional subsidies to help sway the fishermen. Continue reading »
… and PLUTONIUM is the deadliest substance on the planet.
And just to give new readers an idea what we are still facing at Fukushima:
Fukushima reactor No. 4 “SFP contains something on the order of 400.000 kg of hot plutonium”.
“They say that one microgram of plutonium could theoretically kill a person.”
“There are billion micrograms in a kilogram and there are 400.000 hot kilograms in this pool.”
Do the math.
If those fuel rods are catching fire while TEPCO is trying to remove them … it’s ALL OVER.

- New report estimates 278 trillion Bq of plutonium released from Fukushima reactors — Over 200 times higher than amount reported by Tepco — “Highly radiotoxic when incorporated into human body” as it decays (ENENews, Aug 5, 2014):
Evaluation of the Fukushima Accident Source Term through the fast running code RASCAL 4.2 (pdf), ENEA Bologna Research Centre, May 23, 2014: This Report presents the results of the application of the fast-running US-NRC direct code RASCAL 4.2 to the estimation of the Fukushima Source Term. [...] it is plausible that the ventings that TEPCO announced during the accident as being conducted from the wetwell were, as a matter of fact and because of the degraded conditions of the plants, conducted actually from the drywell. […] wetwell properties imply releases which can be several oder of magnitudes lower than those from the drywell […] it can clearly be seen that the most probable path is the combination of Drywell+Direct option […] the true venting path, i.e. from Drywell instead of from Wetwell, is an extremely important issue. […] in several instances when TEPCO tried to operate venting, in order to release pressure outside the building through the stack, it proved impossible […] there are many indications that probably the radioactive material escaped from the drywell; this may have occurred without TEPCO’s immediate knowledge and because of several factors; for example: structural damages to the pipings connecting drywell to torus room (vent piping bellows), due either to the earthquake, and/or to the too violent pressure and temperature increase in the D/W; leakages through the top head manhole, the top head flange, the piping penetrations, the electrical wiring penetrations, the personal airlocks, the S/C manholes, the machine hatches, etc. [...] The value of 1%/h was chosen by ENEA because of the possible highly damaged conditions of the Fukushima NPPs due to the BDB [Beyond Design Basis] earthquake.

- Fukushima Is An Extinction Level Event: 17.91 Billion Lethal Doses (By Ingestion) Chasing Each And Every One Of Us On The Planet … And That’s Just From The Amount Of Cesium-137 (Veterans Today, April 19, 2013):
That’s 17.91 Billion Lethal Doses (by Ingestion) chasing the 7.3 Billion of us on the Planet now and there are 1,946 known radioactive killer isotopic poisons in this list.
Three hundred and fifty years from now (from 2013) is about 14 generations, or the year 2363. Worse still, after 350 years of increased lethality, the Radiotoxicity Level does not decline, it just levels off. We, and all our kind, will simply be dead and gone – finished. Truly, the affair at Fukushima is an Extinction Level Event.

- Three Years later, Japan Finally Tells The Truth: More Fuel Melted At Fukushima (ZeroHedge, Aug 6, 2014):
After years of obfuscation and, simply put, lies; TEPCO has admitted in a new report that more nuclear fuel had melted at the Fukushima nuclear reactor than previously stated. While this is dreadful news, it gets worse, as the report further confirms that despite Abe’s promises and TEPCO’s state-funded efforts to build ice-walls, it may miss an important deadline binding it to clean radioactive water stored inside the Fukushima nuclear plant. Bloomberg reports officials commenting “we are doing everything we can do,” but it appears, that is not enough as tens of thousands of tons of toxic water are expected to remain at the site by the imposed deadline.
As NHK reports, the meltdown was far more significant that originally publicly stated… Continue reading »
- 6.8 quake strikes off Fukushima coast, no abnormalities at nuclear plant (RT, July 11, 2014):
A 6.8 magnitude earthquake hit off the coast of Japan, with its epicenter located some 129 kilometers from the city of Namie in Fukishima prefecture, US Geological Survey reported.
The quake was centered at a depth of about 10km, according to the Japan Meteorological Agency (JMA).
Tsunami advisories were issued for Fukushima prefecture, as well as for nearby Iwate and Miyagi prefectures, but were lifted two hours later.
The quake triggered a small tsunami of up to 20 cm at Ishinomaki in Miyagi prefecture, and other locations in northeast Japan. No major damage was reported.
There were no reports of abnormalities at Fukushima-1 nuclear plant following the quake, TEPCO reported.
And since when is TEPCO trustworthy?
Would they tell us if reactor No.4 SFP has collapsed?

- U.S. firm hired to scrub Fukushima No. 1 water (Japan Times/Bloomberg, June 12, 2014):
Tokyo Electric Power Co. will use a truck-mounted filtration system to extract strontium from water stored at the damaged Fukushima No. 1 power plant as the utility struggles to overcome technical problems with its existing water-processing facility.
Tepco has signed a contract with Kurion Inc. to remove strontium from more than 340,000 metric tons of radioactive water stored at the wrecked plant using the mobile filtration system, the U.S.-based firm said in a statement Monday.
The system will be used to improve site safety while testing of the ALPS processing facility continues. ALPS is designed to remove strontium and 61 other isotopes from cooling and other water tainted by contact with the plant’s melted fuel rods. Strontium has been linked to bone cancer.

- Fukushima worker files historic lawsuit over radiation exposure (RT, May 8, 2014):
A worker at the Fukushima No. 1 nuclear plant has filed the first lawsuit from an employee against plant operator TEPCO due to high levels of radiation he was exposed to during the initial days of the plant’s 2011 disaster.
“I wish [the utility] had informed us of possible risks in advance,” Japanese newspaper Asahi Shimbun cites the 48-year-old man as saying at a news conference in Tokyo on Wednesday. “I want [operator Tokyo Electric Power Company] to create safer conditions for workers because the decommissioning of the reactors will not finish anytime soon.”
The claimant says he was unnecessarily exposed to excessively high levels of radiation due to negligence on the part of TEPCO. He is seeking 11 million yen ($110,000) in compensation from TEPCO. The lawsuit was filed Wednesday in Fukushima District Court.
“After carefully examining the contents of the demand and his arguments, we will sincerely respond to the claim,” TEPCO said in a statement Wednesday.

The pumped out water is later expected to be dumped into the Pacific Ocean.
- Only a third of nuclear reactors may be restarted (Japan Times, April 2, 2014):
Three years after the Fukushima disaster prompted the closure of all of Japan’s nuclear reactors, Prime Minister Shinzo Abe is moving to revive atomic power as a core part of the nation’s energy mix, but many of those idled reactors will never come back online.
Fewer than one-third, and at most about two-thirds, of the reactors will pass today’s more stringent safety checks and clear the other seismological, economic, logistical and political hurdles needed to restart, a Reuters analysis shows..
Hokkaido Electric Power Co., facing a third year of financial losses, is seeking a capital infusion from a state-owned lender, which would make it the second utility after Tokyo Electric Power Co., whose Fukushima No. 1 plant suffered three core meltdowns, to get a government bailout since the March 2011 disaster started.

Contaminated water at the battered Fukushima plant has taken precedence over everything else. As the larger cleanup effort continues and storage space for the water is rapidly running out, scientists suggest dumping it into the Pacific Ocean.
The plant’s chief, Akira Ono, has testified to the seriousness of the situation during a Monday visit by international media, saying that “the most pressing issue for us is the contaminated water, rather than decommissioning. Unless we resolve the problem, fear of the community continues and the evacuees cannot return home,” the AP cited him as saying.

- Japanese Prime Minister Had to Fly In to Fukushima In the Middle of the Night to Get the Scoop from Low-Level Nuclear Workers … Because Tepco Wouldn’t Tell Him the Truth (Washington’s Blog, Feb 28, 2014):
Tepco Wouldn’t Even Tell the Truth to the Japanese Leader
In this 27-second video, Amy Goodman summarizes her interview with Japanese Prime Minister Naoto Kan:
We just came from Tokyo. We broadcast for three days from Japan. And we’re going to play the interview I did with the former prime minister, the one in charge at the time [of the Fukushima disaster], Naoto Kan. He said it was extremely difficult to get a straight answer from TEPCO, the Tokyo Electric Power Company, that ran the plants, and he had to fly in. He figured the only place he could get a straight, nonpolitical answer—he flew in the middle of the night to the plant to talk to the workers to figure out whether he had to evacuate 50 million people in Tokyo.
This is not the first time Tepco has been less than honest: Continue reading »

Japanese themselves are highly divided on the issue [...] shutting down the Fukushima Daiichi nuclear plant will go on for a long time. TEPCO predicts it could last 30 or 40 years. Others say that estimate is blindly optimistic.
- Tepco mis-analyzed 167 samples since 311/ Correct readings can be over 10 times much as wrong ones (Fukushima Diary, Feb 16, 2014):
Following up this article.. [Wrong analysis for 2.5 years] Tepco “All the radiation analysts were outsourced staff. No Tepco employee in Lab.” [URL]
The wrongly analyzed samples are up to 167, Tepco announced in their press conference of 2/14/2014.
They were stating all the nuclides might have been underestimated including Strontium-90, but they re-stated actually it was only all β nuclide to have been underestimated.
Among 20,866 samples to detect all β nuclide from 311 to October of 2013, 0.8% of the samples were analyzed in the wrong manner.
However, they commented the correct reading may be over 10 times much as originally announced data.
For example, last July they measured 5,000,000,000 Bq/m3 of Strontium-90 from the groundwater taken in the seaside of reactor2. (cf, 5,000,000,000 Bq/m3 of Strontium-90 measured from groundwater last July / Tepco not announced for half a year [URL 2]
From this sample, they also measured 900,000,000 Bq/m3 of all β nuclide. The correct reading can be over 9,000,000,000 Bq/m3 with 166 other samples.
As the eyes of the world have been focused on the Unit 4’s removal of spent fuel,

Follow Fairewinds Energy’s Arnie Gundersen as he shows you the 35-ton refueling bridge that fell in the Unit 3 spent fuel pool during the Unit 3 detonation explosion. Do the math. The bottom line here is that TEPCO has just acknowledged that at least 50-tons of rubble has fallen on top of and into the spent fuel pool in Unit 3. What does this 50-ton pile of debris mean to the Unit 3 spent fuel pool and its cleanup?
