South Korean opposition politicians sharply criticised the head of the United Nations’ nuclear watchdog for its approval of Japanese plans to release treated wastewater from the damaged Fukushima nuclear power plant during a tense meeting in Seoul on Sunday.
Rafael Mariano Grossi, the International Atomic Energy Agency’s director general, arrived in South Korea over the weekend to engage with government officials and critics and help reduce public concerns about food safety.
The planned release of the Fukushima plant’s treated wastewater emerged as a major political issue in South Korea after the IAEA last week approved the Japanese discharge plans, saying the process would meet international safety standards and pose negligible environmental and health impacts.
South Korea’s government has also endorsed the safety of the Japanese plans, saying that the contamination levels of water pumped out from the plant would be within acceptable standards and would not meaningfully affect South Korean seas as long as the plant’s treatment systems work as designed.
In his meeting with visiting members of the liberal Democratic Party, which controls a majority in South Korea’s parliament, Mr Grossi said the IAEA’s review of the Japanese plans was based on “transparent” and “scientific” research.
He acknowledged concerns over how the Japanese plans would play out in actuality and said the IAEA would establish a permanent office in Fukushima to monitor closely how the discharge process is implemented over the next three decades.
The politicians responded by harshly criticising IAEA’s review, which they say neglected long-term environmental and health impacts of the wastewater release and threatens to set a bad precedent that may encourage other countries to dispose nuclear waste into sea.
They called for Japan to scrap the discharge plans and work with neighbouring countries to find safer ways to handle the wastewater, including a possible pursuit of long-term storage on land.
The party has also criticised the government of South Korean President Yoon Suk Yeol for putting people’s health at risk while trying to improve relations with Japan.
“If you think (the treated wastewater) is safe, I wonder whether you would be willing to suggest the Japanese government use that water for drinking or for industrial and agricultural purposes, rather than dumping it in the sea,” Woo Won-shik, a Democratic Party politician told Mr Grossi.
The party said Mr Woo has been on a hunger strike for the past 14 days to protest against the Japanese discharge plans.
Further details from the meeting were not immediately available after reporters were asked to leave following opening statements.
Mr Grossi was to fly to New Zealand later on Sunday and would then travel to the Cook Islands as he further tries to reassure countries in the region about the Japanese plans.
Dozens of protesters shouted in a nearby hall while holding signs denouncing the IAEA and Japan.
Hundreds of demonstrators had also marched in Seoul on Saturday demanding that Japan scrap its discharge plans. Those protests provided a tense backdrop to a meeting between Mr Grossi and South Korean foreign minister Park Jin, who called for IAEA’s “active cooperation” in reassuring the South Korean public.
The safety of Fukushima’s wastewater has been a sensitive issue for years between the US allies. South Korea and Japan have been working in recent months to repair relations long strained over wartime historical grievances to address shared concerns such as the North Korean nuclear threat and China’s assertive foreign policy.
South Korea’s assessment about the safety of the discharge plan was partially based on observations by a team of government scientists who were allowed to tour the Fukushima plant in May.
Japanese Prime Minister Fumio Kishida had agreed to that visit during a May 7 summit with Yoon in Seoul, in a show of his desire for improved ties.
In a statement released by state media on Sunday, North Korea also criticised the Japanese discharge plans, warning against “fatal adverse impact on the human lives and security and ecological environment” resulting from the discharge of “nuclear-polluted water”.
The statement, which was attributed to an unidentified official in North Korea’s Ministry of Land and Environment Protection, also criticised Washington and Seoul for backing the Japanese plans.
“What matters is the unreasonable behavior of IAEA actively patronising and facilitating Japan’s projected discharge of nuclear-polluted water, which is unimaginable,” it said. “Worse still, the US and (South) Korea openly express unseemly ‘welcome’ to Japan’s discharge plan that deserves condemnation and rejection, provoking strong anger of the public.”
A massive earthquake and tsunami in 2011 destroyed the Fukushima plant’s cooling systems, causing three reactors to melt and release large amounts of radiation.
Tokyo Electric Power Company Holdings, which operates the facility, has been storing the treated water in hundreds of tanks that now cover most of the plant and are nearly full.
Japanese officials say the tanks must be removed to make room to build facilities for the plant’s decommissioning and to minimise the risk of leaks in case of another major disaster. The tanks are expected to reach their capacity of 1.37 million tons in early 2024.
Japan first announced plans to discharge the treated water into the sea in 2018, saying the water will be further diluted by seawater before being released in a carefully controlled process that will take decades to complete.
