Tepco faces 132 olympic pools worth of radioactive water — Bloomberg

Read this article that explains what is necessary to clean up the contaminated water from Fukushima Daiichi.

” Tokyo Electric Power Co. (9501) has accumulated the largest pool of radioactive water in the history of nuclear accidents. The utility must now decide what to do with it: dump in the ocean, evaporate into the air, or both.

The more than 330,000 metric tons of water with varying levels of toxicity is stored in pits, basements and hundreds of tanks at the wrecked Fukushima nuclear plant. The government said this week it will take a bigger role in staunching the toxic outflow that’s grown to 40 times the volume accumulated in the atomic disaster at Three Mile Island in the U.S.

Processing and disposing of the water, enough to fill a very large crude oil tanker or 132 Olympic-size swimming pools, will be one of the most challenging engineering tasks of our generation, former nuclear engineer Michael Friedlander said. Tokyo Electric has chopped down forest to add more water tanks at the site 220 kilometers (137 miles) northeast of Tokyo.

The steel storage tanks are vulnerable to spills due to earthquakes as well as leaks, representing “a very clear and present danger to the plant site and to the people working there,” said Friedlander, who spent 13 years operating U.S. nuclear plants, including the Crystal River Station in Florida.

“There are really only a few ways you can get rid of it,” Friedlander said. “You put it in the ocean or it’s going to have to be evaporated. It’s a political hotspot, but at some point you cannot just continue collecting this water.” … “
