TOKYO — Japanese Prime Minister Fumio Kishida visited the tsunami-wrecked Fukushima nuclear plant Sunday and said an impending release of treated radioactive wastewater into the Pacific Ocean cannot be postponed.
He said the move is safe but his government will do its utmost to support fishing communities from the potential impact of damaging rumors during the decades-long project.
Kishida made his trip hours after returning from a summit with U.S. and South Korean leaders at the American presidential retreat of Camp David. Before leaving Washington on Friday, Kishida said it is time to make a decision on the treated water’s release date, which has not been set due to the controversy surrounding the plan.
Kishida on Sunday saw wastewater filtering and dilution facilities and met with the plant and company executives. He told reporters that he confirmed their commitment to safely carrying out the upcoming water discharge. To make room for new facilities needed for the progress of the decommissioning, the treated water needs to be disposed of and tanks removed to make room.
The treated water discharge “by no means can be postponed for the decomissioning and Fukushima’s recovery,” Kishida said.
He said he hoped to meet with representatives of fisheries organizations on Monday before his ministers decide the start date at a meeting next week. It is widely expected to be the end of August.
Kishida said the water release is a long-term project and that he is aware of the importance of recognizing the concerns and needs of local fishing groups. “I hope to convey the government position directly to the fisheries representatives,” he said.
Since the government announced the release plan two years ago, it has faced strong opposition from Japanese fishing organizations, which worry about further damage to the reputation of their seafood as they struggle to recover from the accident. Groups in South Korea and China have also raised concerns, turning it into a political and diplomatic issue.
The government and the plant operator, Tokyo Electric Power Co., or TEPCO, say the water must be removed to make room for the plant’s decommissioning and to prevent accidental leaks from the tanks because much of the water is still contaminated and needs further treatment.
Japan has obtained support from the International Atomic Energy Agency to improve transparency and credibility and to ensure the plan by TEPCO meets international safety standards. The government has also stepped up a campaign promoting the plan’s safety at home and through diplomatic channels.
The IAEA, in a final report in July, concluded that the TEPCO plan, if conducted strictly as designed, will cause negligible impact on the environment and human health, encouraging Japan to proceed.
While seeking understanding from the fishing community, the government has also worked to explain the plan to neighboring countries, especially South Korea, to keep the issue from interfering with their relationship-building. Japan, South Korea and the U.S. are working to bolster trilateral ties in the face of growing Chinese and North Korean threats.
South Korean President Yoon Suk Yeol’s government recently showed support for the Japanese plan, but he faces criticism at home. During a joint news conference at Camp David, Yoon said he backs the IAEA’s safety evaluation of the plan but stressed the need for transparent inspection by the international community.
Kishida said Sunday that the outreach efforts have made progress, and that the decision will factor in safety preparations and measures for possible reputational damage to the fisheries. He said the government has provided scientific explanation to counter unscientific criticism, including from China.
A massive March 11, 2011, earthquake and tsunami destroyed the Fukushima Daiichi plant’s cooling systems, causing three reactors to melt and contaminating their cooling water. The water is collected, filtered and stored in around 1,000 tanks, which will reach their capacity in early 2024.
The water is being treated with what’s called an Advanced Liquid Processing System, which can reduce the amounts of more than 60 selected radionuclides to government-set releasable levels, except for tritium, which the government and TEPCO say is safe for humans if consumed in small amounts.
Scientists generally agree that the environmental impact of the treated wastewater would be negligible, but some call for more attention to dozens of low-dose radionuclides that remain in it.
