Contaminated water transfer to end early in June
Tokyo Electric Power Company, or TEPCO, plans to complete the transfer of radioactive water from leaking underground storage pools to tanks above ground at the Fukushima Daiichi nuclear plant early in June.
A series of leaks of highly contaminated water have been found since April 5th in some of the underground storage pools.
TEPCO decided to stop using the underground storage pools and move all of the 23,000 tons of water to tanks.
About 7,000 tons of contaminated water from the No. 1 and 2 pools has already been transferred without trouble.
The utility company plans to install more tanks which can accommodate about 19,000 tons of water to complete the transfer.
The underground pools continue to leak during the operation. The utility pumps the leaked water back to the pools to minimize the environmental impact.
It continues to monitor underground water at 30 wells around and on the sea side of the plant.
No contamination of ground water has been detected yet but TEPCO plans to set up new monitoring wells in locations closer to the underground pools to gather more information about underground conditions.
