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."

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 It uses a newer version of the type of reactor used at Fukushima, a General Electric Type 5 Boiling Water Reactor.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.
