ENGINEERINGNET.EU - "We recognize that bringing the contaminated water under control is a most urgent and serious problem that we must address and we are tackling this by not only implementing emergency measures but also fundamental counter measures", stated Tepco's president Hirose in a video message.
Due to a typhoon, rain water had accumulated in the dam surrounding the contaminated water tanks in Fukushima Daiichi nuclear plant.
'On September 16 we conducted a radiation survey. Water with a radioactive density higher than the limit in the reactor regulation, was pumped back to the tanks', says a technical report, 'when the density was lower than the limit, we discharged the water over the dam', and into the sea.
In all, about 1,000 tonnes of contaminated water was discharged in the ocean. Tepco built the tanks following the 2011 disaster to stock radioactive water.
"We believe that the impact on the surrounded water was limited to the area within the port of the power plant. Monitoring 3 kilometers offshore shows no impact on the water and the wider ocean." Hirose 'deeply apologizes'.
