This affects all of us who border the Pacific... and beyond.

Tepco?
Fukushima operator may have to dump contaminated water into Pacific: As Japan marks the third anniversary of the earthquake, tsunami and nuclear disaster, Tepco is struggling to find a solution for hundreds of thousands of tonnes of contaminated water  
What gives you the right to poison our oceans with radioactivity?  (Ignore our 'work' on the Bikini Islands.) Is this the best idea you can come up with for the continuous leaks and the huge quantity of radioactive water?  Tepco, the company that has gangsters taking over contracts and hiring homeless people to work clean up?  Why should we trust you when you tell us it is safe to do this?

We must never forget Fukushima and the lessons it has taught us.  At least we can see some changing attitudes about nuclear power.

Come swim in the Pacific and get a tan without leaving the water!

New highly radioactive leak at Japan's Fukushima plant
TOKYO (Reuters) - The operator of Japan's Fukushima nuclear plant said on Thursday that 100 metric tons of highly contaminated water had leaked out of a tank, the worst incident since last August, when a series of radioactive water leaks sparked international alarm. 
Tokyo Electric Power Co told reporters the latest leak was unlikely to have reached the ocean. But news of the leak at the site, devastated by a 2011 earthquake and tsunami, further undercut public trust in a utility rocked by a string of mishaps and disclosure issues.

More Fukushima'd than ever....

Fukushima

Fukushima radiation levels underestimated by five times - TEPCO
TEPCO has revised the readings on the radioactivity levels at the Fukushima No. 1 nuclear plant well to 5 million becquerels of strontium per liter – both a record, and nearly five times higher than the original reading of 900,000 becquerels per liter. 
Strontium-90 is a radioactive isotope of strontium produced by nuclear fission with a half-life of 28.8 years. The legal standard for strontium emissions is 30 becquerels per liter. Exposure to strontium-90 can cause bone cancer, cancer of nearby tissues, and leukemia.

Nightmares from Japan

Keeping track of the events. Even by those who have left Japan.

Radioactive water could be soon reaching the sea.

Tsunami debris is beginning to reach the US west coast, but it's highly unlikely it is radioactive.  In fact, it is not a large island of debris but very spread out.  Fukushima's disaster began well after the tsunami.

Check fish with Geiger counters?

You can get your scientists to try and solve the problem.

Or you can indulge in fearmongering.

Only 18 times higher...

The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 millisieverts an hour. 
However, the company said the equipment used to make that recording could only read measurements of up to 100 millisieverts. 
The new recording, using a more sensitive device, showed a level of 1,800 millisieverts an hour. 
The new reading will have direct implications for radiation doses received by workers who spent several days trying to stop the leak last week, the BBC's Rupert Wingfield-Hayes reports from Tokyo. 
In addition, Tepco says it has discovered a leak on another pipe emitting radiation levels of 230 millisieverts an hour. 
The plant has seen a series of water leaks and power failures.

Corporations do not act in the public interest...

They act in their own interests.

Two Workers Were Assigned To Check 1,000 Tanks At Leaking Fukushima
TOKYO (AP) — Japan’s nuclear regulator on Wednesday upgraded the rating of a leak of radiation-contaminated water from a tank at its tsunami-wrecked nuclear plant to a “serious incident” on an international scale, and it castigated the plant operator for failing to catch the problem earlier. 
The Nuclear Regulation Authority’s latest criticism of Tokyo Electric Power Co. came a day after the operator of the Fukushima Dai-ichi nuclear plant acknowledged that the 300-ton (300,000-liter, 80,000-gallon) leak probably began nearly a month and a half before it was discovered Aug. 19. 
In a meeting with agency officials and experts Tuesday night, TEPCO said radioactivity near the leaky tank and exposure levels among patrolling staff started to increase in early July. There is no sign that anyone tried to find the source of that radioactivity before the leak was discovered. 
On Wednesday, regulatory officials said TEPCO has repeatedly ignored their instructions to improve their patrolling procedures to reduce the risk of overlooking leakages. They said TEPCO lacked expertise and also underestimated potential impact of the leak because underground water is shallower around the tank than the company initially told regulators. 
“Their instructions, written or verbal, have never been observed,” Toyoshi Fuketa, a regulatory commissioner, said at the agency’s weekly meeting Wednesday.

Worse to worser to horrific

At Fukushima, we have six top-floor pools all loaded with fuel that eventually will have to be removed, the most important being Reactor 4, although Reactor 3 is in pretty bad shape too. Spent fuel pools were never intended for long-term storage, they were only to assist short-term movement of fuel. Using them as a long-term storage pool is a huge mistake that has become an 'acceptable' practice and repeated at every reactor site worldwide. 
We have three 100-ton melted fuel blobs underground, but where exactly they are located, no one knows. Whatever 'barriers' TEPCO has put in place so far have failed. Efforts to decontaminate radioactive water have failed. Robots have failed. Camera equipment and temperature gauges...failed. Decontamination of surrounding cities has failed. 
We have endless releases into the Pacific Ocean that will be ongoing for not only our lifetimes, but our children’s' lifetimes. We have 40 million people living in the Tokyo area nearby. We have continued releases from the underground corium that reminds us it is there occasionally with steam events and huge increases in radiation levels. Across the Pacific, we have at least two peer-reviewed scientific studies so far that have already provided evidence of increased mortality in North America, and thyroid problems in infants on the west coast states from our initial exposures.
 We have increasing contamination of the food chain, through bioaccumulation and biomagnification. And a newly stated concern is the proximity of melted fuel in relation to the Tokyo aquifer that extends under the plant. If and when the corium reaches the Tokyo aquifer, serious and expedient discussions will have to take place about evacuating 40 million people from the greater metropolitan area. As impossible as this sounds, you cannot live in an area which does not have access to safe water.
The operation to begin removing fuel from such a severely damaged pool has never been attempted before. The rods are unwieldy and very heavy, each one weighing two-thirds of a ton. But it has to be done, unless there is some way to encase the entire building in concrete with the pool as it is. I don't know of anyone discussing that option, but it would seem much 'safer' than what they are about to attempt...but not without its own set of risks.
 And all this collateral damage will continue for decades, if not centuries, even if things stay exactly the way they are now. But that is unlikely, as bad things happen like natural disasters and deterioration with time...earthquakes, subsidence, and corrosion, to name a few. Every day that goes by, the statistical risk increases for this apocalyptic scenario. No one can say or know how this will play out, except that millions of people will probably die even if things stay exactly as they are, and billions could die if things get any worse.

Update 8/21: Definition of anomaly: We have no idea how bad it is.
Fukushima warning: danger level at nuclear plant jumps to 'serious' Japan's nuclear agency dramatically raises status after saying a day earlier that radioactive water leak was only an 'anomaly'
Update 8/23: Finally pleading for international help:
TEPCO, operator of the crippled Fukushima nuclear plant, admits it needs overseas help to contain the radioactive fallout, after 18 months of trying to control it internally. It comes after the latest leak at the facility was deemed a “serious incident. 
"Many other countries outside of Japan have experienced decommissioning reactors, so we hope we can consult them more and utilize their experience,” TEPCO’s vice president, Zengo Aizawa, said at a news conference on Wednesday night. 

"In that sense, we need support, not only from the Japanese government but from the international community to do this job." 

The call comes after one of the 1,060 temporary tanks used to store highly contaminated water sprang a leak on Wednesday, discharging as much as 300 tons of radioactive liquid containing large amounts of cesium. Further tests revealed excessive radiation levels elsewhere in the facility. 

Japan’s Nuclear Regulation Authority (NRA) rated the incident 3 on the International Nuclear and Radiological Event Scale, which spans from 1 to 7.
Update: Just a little more than 200,000 tons of radioactive water.... that's all....
TOKYO — The operator of Japan’s tsunami-hit nuclear power plant sounded the alarm on the gravity of the deepening crisis of containment at the coastal site on Friday, saying that there are more than 200,000 tons of radioactive water in makeshift tanks vulnerable to leaks, with no reliable way to check on them or anywhere to transfer the water. 
The latest disclosures add to a long list of recent accidents, leaks and breakdowns that have underscored grave vulnerabilities at the Fukushima Daiichi nuclear power plant site more than two years after a powerful earthquake and tsunami set off meltdowns at three reactors. 
They come two weeks after the prime minister, Shinzo Abe, promised that his government would take a more active role in the site’s cleanup, raising questions over how seriously he has taken that pledge. Mr. Abe’s government has continued to push for a restart of the country’s nuclear power program, and he heads to the Middle East on Saturday to promote Japanese exports to the region, including nuclear technology.

Worser and worser

Japan nuclear body says radioactive water at Fukushima an 'emergency'
(Reuters) - Highly radioactive water seeping into the ocean from Japan's crippled Fukushima nuclear plant is creating an "emergency" that the operator is struggling to contain, an official from the country's nuclear watchdog said on Monday. 
This contaminated groundwater has breached an underground barrier, is rising toward the surface and is exceeding legal limits of radioactive discharge, Shinji Kinjo, head of a Nuclear Regulatory Authority (NRA) task force, told Reuters. 
Countermeasures planned by Tokyo Electric Power Co are only a temporary solution, he said.
Tepco's "sense of crisis is weak," Kinjo said. "This is why you can't just leave it up to Tepco alone" to grapple with the ongoing disaster. 
"Right now, we have an emergency," he said. 
Tepco has been widely castigated for its failure to prepare for the massive 2011 tsunami and earthquake that devastated its Fukushima plant and lambasted for its inept response to the reactor meltdowns. It has also been accused of covering up shortcomings. 
It was not immediately clear how much of a threat the contaminated groundwater could pose. In the early weeks of the disaster, the Japanese government allowed Tepco to dump tens of thousands of metric tons of contaminated water into the Pacific in an emergency move. 
The toxic water release was however heavily criticized by neighboring countries as well as local fishermen and the utility has since promised it would not dump irradiated water without the consent of local townships.

What was that about how safe our nuclear power plants are?

Fukushima Meltdown Driving Increased Abnormalities Among US Infants
According to a new study (.pdf) published in the Open Journal of Pediatrics, children born in Alaska, California, Hawaii, Oregon and Washington between one week and 16 weeks after the meltdown began are 28 percent more likely to suffer from congenital hypothyroidism (CH) than were kids born in those states during the same period one year earlier. 
CH results from a build up of radioactive iodine in our thyroids and can result in stunted growth, lowered intelligence, deafness, and neurological abnormalities—though can be treated if detected early. 
Because their small bodies are more vulnerable and their cells grow faster than adults', infants serve as the proverbial 'canary in the coal mine' for injurious environmental effects. 
"With the embryo and fetus, there can never be a 'safe' dose of radiation," writes nukefree.org founder Harvey Wasserman. "NO dose of radiation is too small to have a human impact." 
According to researchers from the Radiation and Public Health Project who performed the study, “Fukushima fallout appeared to affect all areas of the US, and was especially large in some, mostly in the western part of the nation.” They add that CH can provide an early measure to "assess any potential changes in US fetal and infant health status after Fukushima because official data was available relatively promptly."

The whole world is Fukushima'd.....

Fukishima nuclear disaster update.

Fukushima Medical Care Provider: Hospital president says people will be healthier after radiation exposure from triple meltdowns — “There is no argument allowed”

Post-Fukushima, Japan’s irradiated fish worry B.C. experts
The numbers show that far from dissipating with time, as government officials and scientists in Canada and elsewhere claimed they would, levels of radiation from Fukushima have stayed stubbornly high in fish. In June 2012, the average contaminated fish catch had 65 becquerels of cesium per kilo. That’s much higher than the average of five Bq/kg found in the days after the accident back in March 2011, before cesium from Fukushima had spread widely through the region’s food chain. In some species, radiation levels are actually higher this year than last.
