Fukushima: At Least 3 Underground Chambers Leaking Radioactive Water
April 9, 2013

At least three of seven underground chambers at the site are now seeping radioactive water, leaving the Tokyo Electric Power Company with few options on where to store the huge amounts of contaminated runoff from the makeshift cooling systems at the Fukushima Daiichi Nuclear Power Plant.
Those systems were put in place after a large earthquake and tsunami damaged the plant’s regular cooling systems two years ago, causing fuel at three of its reactors to melt and prompting 160,000 people to evacuate their homes. Since then, the Tokyo Electric Power Company, or Tepco, has been flooding the damaged reactor cores to cool and stabilize the fuel.
But Tepco has struggled to find space to store the runoff water. It initially released what it said was low-level contaminated water into the Pacific Ocean, igniting furious criticism among neighbors and environmental activists. Traces of radioactive cesium were later found in bluefin tuna caught off the California coast.
Prime Minister Shinzo Abe has stressed that he will not permit Tepco — which has effectively been nationalized following the disaster — to again release contaminated water into the ocean. But Tepco says it already stores more than a quarter-million tons of radioactive water in hundreds of tanks at the site, or in underground pools, and that the amount of runoff could double within three years.
The company has said it is building more storage space, and also filters much of the runoff. But with its underground pools vulnerable to leaks, Tepco is being forced to scramble for alternatives.
Workers at the plant had been emptying the No. 2 underground pool after Tepco found that about 120 tons of toxic water, or almost 32,000 gallons, had breached its inner plastic linings and seeped into the soil. Tepco said the leak appeared to be the biggest since the early months after the March 2011 disaster.
