Download Radioactive water may still be entering tunnels

The operator of the crippled Fukushima Daiichi nuclear power plant faces another challenge in its effort to address radioactive water at the complex.

It says highly contaminated water may still be flowing from reactor buildings into adjacent underground tunnels even after a work to stem the flow ended.

The water in the tunnels is believed to be leaking into the sea. Tokyo Electric Power Company plans to pump the tainted water out of the tunnels and fill them with cement.

To prepare for the process, the firm began work in April to stem the flow of radioactive water between the reactor buildings and the tunnels. It involved freezing some of the water as well as plugging the gaps with filler materials.

TEPCO finished the work on November 6th. But workers found that water levels in the reactor buildings and the tunnels are still linked. They note this suggests that the flow of radioactive water between them may not have been stopped.

TEPCO officials say that if the situation doesn't improve, they may start filling the tunnels with cement even before they finish removing contaminated water.
