Japan’s Fukushima nuclear power plant dumped more than 1,000 tons of polluted water into the sea after Typhoon Man-yi swamped the facility, a plant operate said Tuesday.
Typhoon Man-yi made landfall Monday, flooding many parts of the country including Kyoto.
Enclosure walls around water tanks at the defunct plant, run by Tokyo Electric Power Company (TEPCO), were inundated. The tanks contained toxic water that previously cools broken reactors.
Workers tested the water and despite the fact that it had low levels of radiation, they decided to dump 1,130 tons of it to make room for more volatile water.
"Workers measured the radioactive levels of the water collected in the enclosure walls, pumping it back into tanks when the levels were high," the TEPCO official told the AFP. "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."
Not all the pumps used to dump water were sufficient, however. TEPCO said a water pump did not start quickly enough during the typhoon to get ride of extremely toxic water that tested as unsafe for their workers. It leaked into an enclosure for several minutes.
There is no clear plan for what the plant will do with the thousands of extremely toxic water that it stored.
According to TEPCO another 300 tons of “mildly” contaminated groundwater washes into the ocean every day after passing under reactors.
