|Japan nuke plant dumps toxic water into ocean
The Japanese operator of the leaking Fukushima nuclear plant said they dumped more than 1,000 tons of toxic water into the sea after the recent typhoon.
Typhoon Man-yi smashed into Japan Monday. The rain also lashed near the wrecked plant run by Tokyo Electric Power (TEPCO), swamping enclosure walls around clusters of water tanks containing toxic water that was used to cool damaged reactors.
Some of the tanks were earlier found to be leaking contaminated water.
“Workers measured the radioactive levels of the water collected in the enclosure walls, pumping it back into tanks when the levels were high,'' said a TEPCO official.
“Once finding it was mostly rain water they released it from the enclosure, because there is a limit on how much water we can store.''
The utility said about 1,130 tons of water with low levels of radiation – below the 30 becquerels of strontium per litre safety limit imposed by Japanese authorities – were released into the ground.
But the company also said at one site where water was found contaminated beyond the safety limit workers could not start the water pump quick enough in the torrential rain, and toxic water had leaked from the enclosure for several minutes.
Strontium is a potentially cancer-causing substance that accumulates in bones if consumed.
Separately, about 300 tonnes of mildly contaminated groundwater is entering the ocean every day having passed under the reactors, TEPCO says.--AFP
