Fukushima nuclear plant will start releasing treated radioactive water to sea as early as Thursday

TOKYO, Aug 22 (AP): Japan will start releasing treated and diluted radioactive wastewater from the
Fukushima Daiichi nuclear plant into the Pacific Ocean as early as Thursday — a controversial step
that the government says is essential for the decades of work needed to shut down the facility that
had reactor meltdowns 12 years ago.
Prime Minister Fumio Kishida gave the final go-ahead on Tuesday at a meeting of Cabinet ministers
involved in the plan and instructed the operator, Tokyo Electric Power Company Holdings, to be
ready to start the coastal release on Thursday if weather and sea conditions permit.
Kishida said at the meeting that the release of the water is essential for the progress of the plant
decommissioning and Fukushima prefecture’s recovery from the March 11, 2011, disaster.
He said the government has done everything for now to ensure the plan’s safety, protect the
reputation of Japan’s fishing industry and clearly explain the scientific basis to gain understanding in
and outside the country. He pledged that the government will continue those efforts until the end of
the release and decommissioning, which will take decades.
“The government will take responsibility until the disposal of ALPS-treated water is completed, even
if it takes several decades,” Kishida said.
A massive earthquake and tsunami destroyed the Fukushima Daiichi plant’s cooling systems, causing
three of its reactors to melt and contaminating their cooling water. The water, now amounted to
1.34 million tons, is collected, filtered and stored in about 1,000 tanks, which fill much of the plant’s
grounds and will reach their capacity in early 2024.
The release of the treated wastewater has faced strong opposition from Japanese fishing
organisations, which worry about further damage to the reputation of their seafood as they struggle
to recover from the nuclear disaster. Groups in South Korea and China have also raised concerns,
turning it into a political and diplomatic issue.
The government and TEPCO say the water must be removed to make room for the plant’s
decommissioning and to prevent accidental leaks from the tanks.
Junichi Matsumoto, TEPCO executive in charge of the water release, said in an interview with The
Associated Press last month that the water release marks “a milestone”, but is still only an initial
step in a daunting decommissioning process.
The government and TEPCO say the water will be treated and then diluted with seawater to levels
safer than international standards.
TEPCO plans to release 7,800 tons of treated water in the 17-day first round of the release,
Matsumoto said.
TEPCO plans to release 31,200 tons of the treated water by the end of March 2024, which would
empty only 10 tanks at the site. The pace will pick up later.
The seawater and marine life will be tested and the results will be disclosed on government and
TEPCO websites.
The International Atomic Energy Agency in a final report in July concluded that the release, if
conducted as designed, will cause negligible impact on the environment and human health. After
taking into possible bioconcentration of low-dose radionuclides that still remain in the water, the
environmental and health impact is still negligible, TEPCO officials said.
Scientists generally support the IAEA view, but some say long-term impact of the low-dose
radioactivity that remains in the water needs attention.
Kishida’s government has stepped up outreach efforts to explain the plan to neighbouring countries,
especially South Korea, to keep the issue from interfering with their relationship.
Kishida said the effort has made progress and the international society is largely responding calmly
to the plan. Still, Hong Kong said it would suspend exports from Fukushima and nine other
prefectures if Japan went ahead with the plan, while China has stepped up radiation testing on
Japanese fisheries products, delaying customs clearance.
TEPCO said it is working toward accepting application for damages caused by China’s export
restrictions on Japanese seafood. (AP)
