TEPCO says 100 tons of tainted water leaked at Fukushima

A new leak of 100 tons of highly radioactive water has been discovered at Fukushima, the plant's operator said Thursday, after it revealed only one of nine thermometers in a crippled reactor was still working.

The toxic water is no longer escaping from a storage tank on the site, said a spokesman for Tokyo Electric Power Co (TEPCO), adding it was likely contained, but the news is a further blow to the company's already-battered reputation for safety.

"As there is no drainage way near the leak, which is in any case far from the ocean, it is unlikely that the water has made its way into the sea," he said.

The tank, one of hundreds at the site that are used to store water contaminated during the process of cooling broken reactors, sits around 700 meters from the shore.

The water it contains is highly radioactive, with a beta radiation reading "at 230 million becquerel per liter," he said.

That contamination level compares with government limits of 100 becquerels per kilogram in food and 10 becquerels per liter in drinking water. A becquerel is a unit of radioactivity.

Beta radiation, including from cancer-causing strontium-90, is potentially very harmful to humans and can cause damage to DNA. But it is relatively easy to guard against and cannot penetrate a thin sheet of aluminium.

"We are now in the process of recovering the leaked water and the earth it has contaminated," the spokesman added.

The tank holds water filtered to remove cesium but which still contains strontium, a substance that accumulates in bones and can cause cancer if consumed.

About half of the beta radiation from the latest leak is thought to be strontium-90, TEPCO said, meaning its concentration level is nearly four million times the legal limit of 30 becquerels per liter.

Still no one in jail, no fines, posts record profits and these boobs are still in charge... doesn't compute :(

Fast track the opening of the other plants. We really, really promise it won't happen again.

“As there is no drainage way near the leak, which is in any case far from the ocean, it is unlikely that the water has made its way into the sea,” he said.

100 tons of water is about 100,000 liters, which is a rather large amount to have simply vanished. Do they really have no idea where it went? Is it trapped in catchment facilities, or was it absorbed by the earth? If the latter, it will eventually reach the ocean; that, or it will merge with aquifers. Don't know which is worse.

100,000 liters isn't that big of a volume - it's less than a 5x5x5m cube.

100 tons here, 100 tons there....but in reality, what is to be done. It's so easy to criticize but much harder to actually do something. They may could be more open but the problem is much more complex than the cynical poster is what to acknowledge.

555 might not be large?, but you have to remember it is highly toxic, and if they can loose that amount of toxic water with no idea where it went...well it's no wonder they are unable to compensate their victims as the probably have lost that 101010 stack of claims

after it revealed only one of nine thermometers in a crippled reactor was still working.

There's no connection between the leaked water and the thermometers. The No2 reactor had just two working thermometers to measure the temperature inside the reactor containment vessel. The thermometer at the bottom was connected to 220 volts instead of 100 volts and burnt it out.

TEPCO will try to replace it but its difficult because the radiation inside the No2 reactor building is very high severely limiting worker time inside. A new thermometer will have to be fitted inside a pipe. If the final thermometer fails, TEPCO will have no idea of the temperature inside the containment vessel which has the melted fuel sitting on its bottom, and probably already burnt into the concrete base by 60 cms and will soon escape from that.

Its not good to go from 9 original thermometers down to 1.

Time for a new approach with the water. TEPCO should pump it out and load it onto sea tankers to go to a new location for cleaning and removing the radiation. This should be carried out by a new company,

In addition, the gov't needs to form a new agency for dealing with the nuclear disaster site, the decontamination and the construction of the storage depot for nuclear waste.

Its in the interests of the country to remove TEPCO which should also be banned from operating any nuclear plant again, and in fact, the company should be sold off to recoup some of the ¥10 trillion of public money it has received to date.

Oh, really? So, where do you suppose it went? Water runs downhill, just the same as the shit TEPCO keeps spouting!

Here we go again! No thanks stupid Tepco!!

And for $50 which Japanese politician stood up in front of the IOC and said "it is all under control"?

I suppose the big question is for how long can this go on? Sooner or later the national government is going to have to either man up and take control away from TEPCO, or admit defeat and allow the grown-ups to come in and manage the cleanup (the IAEA).

I wish I knew how to give this 100 thumbs up.

Hongo - you forgot option 3: Pretend everything is OK and declare inconvenient news such as this a state secret. Keep taking the brown envelopes and getting the other generators back online. Profits beat morality every time in this neck of the woods.

How Abe can tell the IOC everything is under control is beyond me. What a liar. And TEPCO needs to be sold off with some higher ups going to jail. But, I suppose they'll just keep being rewarded.

The accident with the water tank happened because of negligence and incompetence. The accident with the No2 reactor thermometer happened because of negligence and incompetence.

Do we really want this to be the company removing the thousands of spent fuel assemblies from the pools and trying to retrieve the melted fuel from inside the reactors?

Well, who knows if it just contaminates the groundwater in Fukushima. I noticed they dont check for SR90 btw http://atmc.jp/water/

According to NHK, (who if anything would seek to minimize the safety concern involved) the levels of radiation in that 200,000 lbs. of water leaked into the surrounding area averaged 8 MILLION times higher than the levels the government currently considers acceptable to dump into the sea. So to say it's a bit of a problem...is a bit of an understatement, don'cha think?!

But by all means, let's push on with "fast-tracking" other nuclear power plants back into commission, right? After all, which is really more important~the present and future safety of the nation, or the personal political reputation of its smugly overconfident prime minister?

Does anybody believe that it was "only" 100 tons? TEPCO has no cred left, unless you're a politician. The government seems to believe any BS that TEPCO says.

their belief of free and safe energy they need to feed their egocentric lifestyle.

OK, we understand you don't like Japan. But how does this post rate as anything other than a rant?

It feels like every month there is a report of a new leak. In searching TEPCO+water+leaks, I was overwhelmed by the sheer number of leaks that have already occurred at Daiichi and posted links to a few and was thinking that if TEPCO can build a freeze wall why not a 5 meter thick cement wall to keep the contaminates from leaking into the sea. Mind you the so called decontamination process f the "tainted water" only removes cesium while leaving the other harmful contaminates in the water.

In reading a past article on JT I learned froom a poster that Daiichi was built on top of a water table that ultimately feeds into the Tokyo water supply.

TEPCO says up to 500 tons of groundwater flowing into Fukushima nuclear plantNational Sep. 21, 2011

This was documented by foreign sources within the first two weeks of the disaster. It has taken TEPCO over six months to release the info? There is a large water table under the dai-ichi plant and the earth cracked in the quake and subsequent explosions. The thing is, if the water can get in it can also get out! Oh, and did I mention that water table feeds into Tokyo's water supply? TEPCO and the J-Gov sure as heck won't mention it

Why the heck did people thumb down my comment about the volume of water? 100 tons = approx 100,000 L = 4.6 m3. That's smaller than a 5x5x5m cube.

It's just a fact, folks.

OK, just one question: Why would anyone get away with call this a "leak"? That infers water getting out without you knowing. Simply, they chose to release it or they chose to ignore it. Both are criminal actions. What doe it take to put someone in jail?

Good to know that they are handling things, some bows from the management and everything will be okay, don't worry about the glowing sushi in the sea.

Wait I just read some crazy stuff, I need corroboration or something. Did anybody know abut this

According to whistleblowers in the U.S. non-proliferation agency, highly reactive uranium from dismantled U.S. warheads stored in the Fukushima spent-fuel pools readily ignited after the quake knocked out the water pumps. A transport casket of elongated shape resembling a missile was sky-hooked out of a pool by helicopter soon after the tsunami, but the remainder of the weapons-grade stock was too heavy to remove. The series of detonations prevented repair crews from accessing controls of the reactor cores, which eventually melted through the containment chambers and into the subsurface soil.

When the quake and tsunami hit on March 11, only three reactors out of a total six at Fukushima were scheduled to produce electricity yet in actuality five were operational. Since then plant workers disclosed that the supposedly empty Reactor 4 had been refitted with a new steel shroud in secret by GE and that it was fully loaded with new fuel rods. The two extra reactors were running clandestine operations, the likeliest purpose being the enrichment of uranium prior to extraction. By no coincidence, Hitachi Electric and Honeywell are partners in developing a laser-plasma system to extract highly pure plutonium and uranium

It's amazing how an incompetent company like TEPCO who could't even look after the nuclear reactors in the first place are deemed competent enough to make it safe. Looks like the level of corruption between TEPCO and the ruling classes is as deep as the government debt.
