Japan’s environment minister said on Tuesday that Tokyo Electric Power will soon run out of room to store the radioactive water from its destroyed Fukushima nuclear power plant, and they will now have to dump it into the Pacific Ocean.
Tokyo Electric (or Tepco) has collected more than 1 million tonnes of contaminated water from the cooling pipes used to keep fuel cores from melting since the plant was devastated by an earthquake and tsunami in 2011. Yoshiaki Harada, the minister, told a news briefing in Tokyo:
“The only option will be to drain it into the sea and dilute it. The whole of the government will discuss this, but I would like to offer my simple opinion.”
If the Japanese government tells Tepco to dump the waste into the sea, it would anger neighbors such as South Korea, who is already concerned about how the the country will deal with the Fukushima water.
The relationship between the East Asian nations is already tense following a dispute over pay for Koreans ordered to work in Japanese factories during World War Two. A South Korean diplomat (who requested anonymity due to the sensitivity of bilateral ties) told Reuters:
South Korea’s foreign ministry said in a statement said it had asked Japan “to take a wise and prudent decision on the issue.”
Coastal nuclear plants regularly dump water into the ocean that contains tritium, which is an isotope of hydrogen that is hard to separate. It is considered to be nearly harmless.
Tepco also faces resistance from fishermen, after the utility company admitted last year that the water in its tanks still included contaminants beside tritium.
