Fukushima dumps first batch of "once-radioactive" water in sea

The operator of Japan's Fukushima on Monday began releasing previously radioactive groundwater from the crippled nuclear plant into the sea, saying a filtration process had made the discharge safe.

okyo Electric Power Co (TEPCO), which operates the plant in eastern Japan, said that on the first day it had released 850 tons of groundwater, which had become radioactive after flowing near the plant.

But it has yet to find a solution to deal with the other 680,000 tons of highly radioactive water stored on site.
This includes water used to cool reactors when they were knocked out by a towering tsunami on March 11, 2011.

Local fishermen have still not agreed to any discharge of water collected from the reactor buildings even after it is filtered.
