Tokyo Electric Power Co. <9501> on Tuesday continued its work to remove highly radioactive water that flood the basements of reactor turbine buildings at its crippled Fukushima No. 1 nuclear power plant.
At the same time, the plant operator also worked to seal underground tunnels that stretch from the turbine buildings toward the sea after detecting high levels of radiation from water contained in one of the tunnels.
In the basement of the turbine building for the No. 1 reactor, one of the four reactors that were severely damaged by the devastating earthquake and ensuing tsunami on March 11, Tokyo Electric continued to pump water out of the basement into the steam condenser connected to the turbine.
As a result, water levels inside the basement dropped slightly, Tokyo Electric officials said.
At the No. 2 and No. 3 reactors, also damaged heavily, the steam condensers were nearly filled with water. Tokyo Electric started to empty tanks nearby so that it can pump water out of the condensers into the tanks.
