Radioactive water mistakenly pumped back into Fukushima plant basement
Japan’s Tokyo Electric Power Company says some 200 tons of radioactive water was inadvertently pumped in the wrong direction--out of a storage tank and back into a basement.
Over 200 tons of radioactive water was erroneously pumped into a basement area at the Fukushima Daiichi atomic power plant between April 10-13, Tokyo Electric Power Company (TEPCO) said April 15.
After a partial meltdown in 2011, water has been continuously poured onto the reactor cores to cool them.
The water falls into basement levels and is then pumped out into specially constructed storage tanks.
But the Tokyo Electric Power Company Plant says for unknown reasons, the pump flow was reversed between April 10 to 13, and the water was pumped back into a basement.
Hundreds of tons of radioactive water have leaked into the ocean since 2011, and radiation concentrations in regional groundwater and seawater are still currently above acceptable levels.
