TEPCO shows plant to media

Tokyo Electric Power Company (TEPCO) has shown media its process of discharging treated and diluted water from the Fukushima Daiichi nuclear power plant into the sea on Sunday.

The treated water is flowing into an undersea tunnel on its way to being released into the ocean. TEPCO also said, seawater samples show no abnormality in radiation levels and it expects to discharge 7,800 tons of water by around September 10 as planned.

More than 1,000 tanks at the plant are now used to store treated water.The plant suffered a triple meltdown in the 2011 earthquake and tsunami. Since then, water used to cool molten fuel at the plant has been mixing with rain and groundwater.

Before the release, the operator is diluting the treated water to reduce tritium levels to about one-seventh of the World Health Organization's guidelines for drinking water.
