Japan dumps thousands of tons of radioactive water into sea

Tokyo (CNN) -- Japan began dumping thousands of tons of radioactive water into the Pacific Ocean on Monday, an emergency move officials said was needed to curtail a worse leak from the crippled Fukushima Daiichi nuclear power plant.

In all, about 11,500 tons of radioactive water that has collected at the nuclear facility will be dumped into the sea, officials said Monday, as workers also try to deal with a crack that has been a conduit for contamination.

The radiation levels were highest in the water that was being drained from reactor No. 6, the officials said.

These are the latest but hardly the only challenges facing workers at the embattled power plant and its six reactors, which have been in constant crisis since last month's ruinous earthquake and tsunami.

Officials with Tokyo Electric Power Company, which runs the plant, proposed the release of excess water that has pooled in and around the Nos. 5 and 6 reactors into the sea. But most of the dumped water -- 10,000 tons -- will come from the plant's central waste treatment facility, which will then be used to store highly radioactive water from the No. 2 unit, an official with the power company said.

The water in reactors Nos. 5 and 6 is coming from a subdrain and wasn't inside the building itself, officials said. Tests suggest that groundwater is the source of the contamination in these two units, but they are not certain.

Japanese Chief Cabinet Secretary Yukio Edano called the dumping "unavoidable." The liquid was most likely contaminated in the process of trying to cool nuclear fuel rods.


The scope of the dump was staggering.

"For an idea about how much is 11,500 tons, one metric ton is 1,000 kilograms or about 2,200 pounds, which is close to an English ton. Water is about 8.5 pounds per gallon, so one ton is about 260 gallons," said Gary Was, a professor of nuclear engineering at the University of Michigan. "So 11,500 tons is about 3 million gallons. A spent fuel pool holds around 300,000 gallons. So this amount of water is equivalent to the volume of roughly 10 (spent fuel pools)."

It could take 50 hours to dump all the water, Tokyo Electric said.

The dumping of so much radioactive water into the ocean conjures fears of mutated sea life and contamination of the human food chain, but one expert said the radiation will be quickly diluted, minimizing risk.

"What we have to watch is how these materials accumulate in food products and then could be consumed by people," something that can be monitored, said John Till, president of Risk Assessment Corp.

"The ocean is so vast that this material would dilute very rapidly and I wouldn't see any lasting effects at all," he said.

The build-up of water could cause problems around the nuclear facility, which is 240 kilometers (150 miles) north of Tokyo, Edano said Monday.

Authorities have made a priority of dealing with water from the No. 2 unit, some of which has been gushing into the sea through a crack in a concrete shaft.

"The radioactivity level is very high near the No. 2 reactor, and we know this. We have to stop the leak as early as possible to prevent this from going into the sea," Edano said. "The radioactivity level is much less in the water from the Nos. 3 and 4 units."

Nuclear and Industrial Safety Agency officials said Monday night that the hope is that pumping out the No. 2 reactor turbine plant will lower the water level enough that contaminated liquid won't be able to reach the sea.

"I am not able to say for certain whether or not this will be the last discharge, but we certainly would like to avoid releasing any such water into the sea as much as possible," agency spokesman Hidehiko Nishiyama said.

Officials were still awaiting test results to confirm the water pouring into the ocean is leaking from the highly radioactive No. 2 reactor.

"We don't know clearly, but we feel it is somehow leaking from Unit 2," Nishiyama said. Even if the water is confirmed to have come from the reactor, neither Tokyo Electric nor government officials know how it is making its way from the reactor to the leaking pit, he said.

Once the water is pumped out of the waste treatment reservoir, the agency believes it can safely transfer the water from the basement of the No. 2 turbine plant to the reservoir without further leaks, he said.

Though Japanese officials say the water being discharged is less radioactive than the water now leaking into the sea, its top concentration of radioactive iodine-131 is 20 becquerels per cubic centimeter, or 200,000 becquerels per kilogram. That's 10 times the level of radioactivity permitted in food. But since it's being dumped into the Pacific, it will be quickly diluted, according to Dr. James Cox, a radiation oncologist at Houston's MD Anderson Cancer Center and a CNN consultant.

Reactors No. 1 and No. 3, which have lower levels of water, need to be drained as well. Tokyo Electric's plan is to pump that water to other storage tanks, including some that still need to be set up.

Attempts to fill the 20-centimeter (8-inch) crack outside the No. 2 reactor's turbine building -- on Saturday by pouring in concrete, then Sunday by using a chemical compound mixed with sawdust and newspaper -- were not successful.

    • what i want to know is this now considered worse than chernobyl not the potential to but actually .the next thing i want to know and i mean right down the middle not one extreme or the other is it time to break out iodide pills and bottled water in the us .because the questions that regular people have is things like if my kids walk in the rain to the bus stop or swim in thier inground pool next month on the east coast of the united states will they eventually get cancer .i am a little less than a laymen on this topic (somewhat well read ) and parents where ilive are asking me this stuff and every thing in me wants to say no because most of the research i've read says there has been worse exposures than this and we are all still here(that is a very general statement).but with conflicting info it's very hard and frankly i am tired of worrying about it.not that anyone has the answers and in some ways just venting . .and to all of japan my prayers.i posted almost the exact same post to arch druid but thought it was worth posting agian

    • "As officials mull other ways to cut off the leak at its source, workers will install a silt fence along a damaged sea wall surrounding the plant, Nishiyama said. The aim of this screening, usually used to halt erosion at construction sites, is to prohibit the spread of radioactive particles into the sea."

      It seems to me this will not be enough. Concrete would be better or dredge up sand and then pump the water out and filter it. The filters need to at least be reverse osmosis which is a selective membrane.

      "To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely."

      Thank you Russia for helping.

    • "Workers also have injected a dye tracer into the water to allow them to track the dispersal of such particles, the spokesman added."

      This is very good news indeed. it makes me believe that someone is on the job that truly cares. The normal response of the nuclear industry is to cover up everything. Radioactivity is a tracer in itself but an invisible one and the monitors do not seem to be enough. The dye should really help. Thank you to whoever initiated this. It's been on my mind for several days but I never posted it.

    • To Hell with all of Them!!! Just blowing smoke up people's asses... They know they are Doomed.... So let Them Die... It was their Bad Decision.... Don't kill my future and my grandchildren's for you idiotic ideas.... Let that island and it's sad inventors stay there and deal with the trauma of their creation!!!!

      Yup.... I posted this last night. I did my best to avoid this news and even told friends how upset I was, and was trying to forget about this Terrible news.... So I went to hang out at Ziggy Stranges Music Lounge... Doing so took alot of the edge off, but I was posting music with tears running down my face... Because every song I posted made me think more of the current events in Japan. I was not escaping the news, I was actually amplifying it, I was getting more angry by the minute. For these "Scientists" to be talking about how worried we should NOT be, it took me back to last April. How the news media sat there and said there was a Busted Well and oil was leaking in the Gulf of Mexico. They never did step up to just how much was leaking and did their best to show there was nothing to worry about.... I think it was Wolf Blitzer that I was watching this weekend, he stated that over 260 Million Gallons of oil may have leaked into the Gulf.

      I get very frustrated with our news media. When I said "To Hell with all of Them!!!" I was speaking of the "Scientists" not about the people of Japan. My wish would be that they find a way to a mainland, sooner than Later. I am posting this to say:

      "I Apologize to all of you especially the 5 that gave the Thumbs Down on this comment." I meant to demean None of you.

      I will use better judgment with all future comments.

      "Peace"

      Japan will not be scapegoated for this i assure you.
      Perhaps the silver lining is that we will all learn more about the science and history of nuclear energy.

    • Well I am sure glad that this was all under control and that there was no meltdown or anything like that.
      Now that it can just be flushed into the ocean it won't be Japans problem anymore. That sure takes care of it .

      "What a total Crock of Shit!!!!" I am sorry folks but I am furiously pissed off with this news!!!!" If the water was of little damage and would "Dilute" than why the Hell could they have not tubed the water to a local lake or reservoir???? They always wanted to say what a great idea and just how fluent and safe these reactors were.... "REALLY????" Built right off the ocean shore? Are you kidding me??? How safe could that be to begin with!!!??? It would seem that they would have built it on higher ground with run off ponds if needed... Man I tell ya' I need to go listen to some music, I have not been this angry in a long time....

      Please excuse my rant....

      Not to save their island but to save the rest of the world from a much bigger meltdown.
      I agree that this is horrible!
      But we have been dealing with nuclear waste for 66 years now and this is a tiny amount compared to what has been released in the past.
      Testing of hydrogen bombs in Nevada, Utah and the South Pacific during the 1960s released radiation into the atmosphere and oceans and soil equivelant to 20,000 bombs dropped on Hiroshima.
      I am not trying to be a nuclear apologist. This is sickening!
      I'm merely attempting to point out that the planet, fauna and flora seem to get over it within a decade with little or no sign of long-term genetic mutations according to scientists.
      Just look at Japan after WWII. Or Chernobyl 25 years after its meltdown. Most of the deaths immediately followed the initial explosions. Life soon began to thrive and our lifespans continue to increase.
      There is an enormous amount of hysteria and misinformation surrounding this subject.
      Natural radon gas seeping into our basements poses a greater health risk to us than what's going on in Japan.

      We joined ashrams, did yoga, discovered Christ, became Pagans, snorted coke, smoked bongs, danced disco, ate organic, protested endlessly and wrote computer code on acid.
      But how many of us have even planted a tree or spent some time/money to save a rainforest?
      My hippy friends in Mendocino, CA are mostly on SSI now. I don't understand. I thought the countercultural dream was to become self-reliant and change the world for the better..

      PART TWO...

      As officials mull other ways to cut off the leak at its source, workers will install a silt fence along a damaged sea wall surrounding the plant, Nishiyama said. The aim of this screening, usually used to halt erosion at construction sites, is to prohibit the spread of radioactive particles into the sea.

      Workers also have injected a dye tracer into the water to allow them to track the dispersal of such particles, the spokesman added.

      Addressing the issue quickly is critical because officials believe it is a source of alarmingly high radiation levels in seawater near the plant, as well as in nearby groundwater.

      Complicating the situation is the fact that, in some cases, authorities don't even know how much radiation is getting out.

      After some high-profile errors, little new information on water, ground and air radiation has been released since Thursday. One reason is that the dosimeters being used don't go above 1,000 millisieverts per hour, said Junichi Matsumoto, an executive with Tokyo Electric.

      Authorities know the water in the cracked concrete shaft is emitting at least that much radiation -- which equates, at a minimum, to more than 330 times the dose an average resident of an industrialized country naturally receives in a year.

      Plugging the external leak is job one, in order to prevent the outflow of radiation into the Pacific. But it may not be the most difficult, or important, task ahead.

      Authorities still have to figure out how the tainted water got into the concrete shaft in the first place. The water had to come from somewhere, potentially traveling across melted-down nuclear fuel in the reactor's core before somehow reaching the outside.

      "We were assuming and hoping (that water) would stay in the containment vessel as vapor after being cooled," Nishiyama, the nuclear safety official, said Sunday. "However, it may have flowed into the building, and then the trench."

      Determining why and how that happened -- and what to do about it -- may be "exceptionally challenging," said physicist James Acton, with the Washington-based Carnegie Endowment think tank. Officials may have to inspect a complex array of pipes inside the dangerous radioactive environment inside the containment buildings.

      The state of the Nos. 5 and 6 units is another new problem. Water in their turbine buildings' basements threatens the power supply for the system used to cool nuclear material in these units' spent fuel pools, Edano said. This makes it imperative to pump out that water, which will end up into the sea like that from around the Nos. 3 and 4 units.

      "Though those reactors are stable at the moment, the growing water level in the turbine houses may disturb their stability," he said.

      The effort to keep the Nos. 1, 2 and 3 reactor cores and spent fuel pools cool took a step forward Sunday, when the electricity source powering those three units' cooling systems was switched from a temporary diesel generator to a more permanent, external power supply, according to the International Atomic Energy Agency's website.

      Authorities hope this step, as well as preventing damage to the Nos. 5 and 6 units' power supply, will help to minimize the prospect of any more radiation that might contaminate tap water or food.

      Farmers have pushed for lower standards on radiation in food, calling them unnecessarily stringent. On Monday, Edano said these limits would not change, even as he outlined a process in which sales restrictions on certain crops, in certain areas, would be lifted if they test safe three times in a row.

      In the long run, utility and government officials want to make sure the nuclear fuel, and the potentially cancerous materials it can release, never poses a threat again.

      One option being considered, a Tokyo Electric spokesman said Monday, is to wrap some or all of the reactors' containment buildings in massive amounts of sheeting. But for now, the aim is to make sure that the nuclear fuel rods do not overheat -- and release more radiation into the air, water and ground.

      "Finally, we (need to) establish a long-term policy to cool the reactors," said Nishiyama, while acknowledging that much work needs to be done in the meantime.
