Leak Found In Fukushima Tank Holding Radioactive Water

The fallout from tsunami damage at Japan's Fukushima plant isn't over yet. New submitter OldJuke writes "Tokyo Electric power Co. said about 120 tons of the water are believed to have breached [a water storage tank's] inner linings, some of it possibly leaking into the soil. TEPCO is moving the water to a nearby tank at the Fukushima Dai-chi plant — a process that could take several days ...More than 270,000 tons of highly radioactive water is already stored in hundreds of gigantic tanks and another underground tank. They are visible even at the plant's entrance and built around the compound, taking up more than 80 percent of its storage capacity. TEPCO expects the amount to double over three years and plans to build hundreds of more tanks by mid-2015 to meet the demand."

It sounds nice but what tends to happen is it settle to floor, get picked up by pants and tiny creatures concentrating it again, the eaten by fewer bigger creatures concentrating it more, and finally poisioning us we we go to eat fish.

Yes if you had some way to spread it over a very very large area of sea it would be fine probably, but you'd likely need to move it out to deep water with container ships, and then you'd have to do something with the contaminated ships. I suppose you might just scuttle them. Anyway just dump it in the ocean sounds simple but doing right ( if there is a right way ) is risky and expensive.

You're talking about Hanford. Approximately one third of Hanford's waste storage tanks are known to have been or be leaking into the groundwater, having contaminated approximately 270 billion gallons or one billion cubic meters of aquifers. This contaminated groundwater is expected to reach the Columbia river in 7 to 45 years, and start contaminating everything along the river from Eastern Washington to Portland and the Pacific ocean shortly thereafter. The loss of real estate values along that river is a very real concern. Waterfront property is normally very valuable. Waterfront property on a radioactive river, less so.

Currently there is no practical plan to deal with this situation nor adequate budget to even stop it from getting worse. It is likely impossible to prevent this radioactive waste from reaching the Pacific. The Columbia river is quite a considerable river, 4th largest in the US by volume and the largest draining into the Pacific. Though Hanford is the most highly contaminated nuclear site in the US - containing approximately 2/3rds of all US high-level waste, it still retains an operating nuclear power generating station to this day. It uses a newer version of the type of reactor used at Fukushima, a General Electric Type 5 Boiling Water Reactor.

Over $30 billions (pdf) have been spent cleaning up Hanford already. 20 years into the initial 30 year plan only minor progress has been made. The vitrification plant, for example, is not expected to complete vitrification operations for another 34 years from now - and that may be optimistic, meaning we are further from the end now than when the work was begun. The estimate for the cost of the remaining cleanup is $112 billion and is, given the nature of such things, likely to be at least three times even that.

Although the so-far estimated cost of $145 billion is very high it is important to remember than Hanford was a critical part of the Manhattan Project, essential for developing the technology and materials that made the US the first nuclear weapon capable global power at a critical cusp of international relations. The cost of not doing that might have been much higher than cleaning up or living with this mess will be.

Cleaning up Fukushima will cost far more than cleaning up Hanford. Cleaning up Chernobyl will also be more costly, to the extent cleanup is possible at all. If you add up the cleanup costs of all three and the off-book costs of getting rid of the current stock of spent nuclear fuels you could probably outfit the entire world with alternative electrical energy solutions like geothermal, wind and solar for less. On this scale a manned Mars colony would be a trivial side project. Of more concern might be that cleaning up these messes entirely is quite simply not possible, even given the full weight of the national economies involved. It cannot be done. We have developed the power to create problems we cannot cure no matter how hard we try.

This is completely off-topic and I expect it to be moderated that way and that's OK.

The costs of combating the ideas of Fascism, Global communism (or what was presented as such), Japanese imperialism, militarized Islam and other such notions offensive to personal liberty so *far* outweigh the costs in lives and treasure of these accidental excursions into nuclear physics as to be on an entirely different scale. It seems the pen is still mightier than the sword even when the sword is a MIRV.

What strange fools these mortals be.

That's not totally clear. A strong immune system can often kill off a cancer before it becomes a problem. Usually before it's detected. (Admittedly, not always. Sometimes it's a cance of the immune system. Or of an area that the immune system can't reach.)

So, yes, some of it's chance. Some of it's your genetic history (epigenetic as well as inherent). Some of it's diet. Perhaps some of it's exercise...though I'm not clear whether exercise creates or prevents it, or perhaps both.

Note that the dose of radiation that gives one person cancer will leave another unaffected. This is a combination of lottery and everything else. It's not pure lottery. But it's also not pure everything else.

What you CAN say is that if you expose a population to a certain level of radiation, then number of cancers will increase by a certain amount. There are large error bars except at the extreme ends, and possibly there, but it's still a reasonably defensible statement. (N.B.: *I* couldn't make that statement, as I can't quantify any of this. But I assert that there are those who reasonably can make that statement, though they *ought* to be more explicit about the error bars than I ever hear them being.)
