UN Endorses Japan’s Plan to Release Treated Fukushima Water into Pacific Ocean


The United Nations (UN) nuclear agency, the International Atomic Energy Agency (IAEA), has given its endorsement to Japan’s proposed release of treated radioactive wastewater from the damaged Fukushima nuclear plant into the Pacific Ocean. The decision comes after a two-year safety review conducted by the IAEA, which concluded that the plan meets international standards and would have a negligible impact on the environment and human health. However, the release plan has faced opposition from neighboring countries, including China and South Korea, as well as concerns from local fishing organizations. This article examines the IAEA’s endorsement, the reactions from various stakeholders, and the ongoing debate surrounding the release.

UN Endorsement and Safety Assessment:
IAEA Director-General Rafael Grossi submitted the final assessment of Japan’s plan to Prime Minister Fumio Kishida, describing it as a comprehensive, objective, and scientifically sound evaluation. The report acknowledged the societal, political, and environmental concerns associated with the release but ultimately concluded that the planned discharge would have minimal radiological impact. The IAEA recognized the use of a proven method—widely employed in other countries such as China, South Korea, the United States, and France—of diluting treated radioactive wastewater for gradual release into the sea. The water, mostly containing cesium and other radionuclides, will be further filtered to meet international standards and then diluted by a factor of 100 with seawater before release.

Opposition and Concerns:
Opposition to Japan’s plan has been voiced by groups in South Korea, China, and Pacific Island nations due to safety concerns and political reasons. Local fishing organizations fear potential damage to their reputation, even if their catch remains uncontaminated. Haruhiko Terasawa, head of the Miyagi prefectural fisheries cooperatives, expressed concerns about the long-term impact of the released water, which could persist for up to 30-40 years. Some scientists also call for more transparency in sampling and monitoring, citing uncertainties related to long-term, low-dose exposure to radionuclides.

Japanese Government’s Response:
Japan has sought the IAEA’s support to gain credibility for its plan. Prime Minister Kishida assured that Japan would provide detailed explanations based on scientific evidence and maintain a high degree of transparency domestically and internationally. The government emphasizes the need to remove the water to prevent accidental leaks and create space for the decommissioning of the damaged nuclear plant. Regulators have completed the final safety inspection of the equipment, and Tokyo Electric Power Company Holdings (TEPCO) is expected to receive a permit for gradual water discharge. However, the exact start date for the release is yet to be determined.

Reactions from Neighboring Countries:
China and South Korea have strongly opposed Japan’s plan and raised concerns about the potential threat to the marine environment and public health. China called for the suspension of the water release, dismissing the IAEA’s report as insufficient. South Korean consumers have stockpiled sea salt and seafood in anticipation of the water release, reflecting their anxieties about food safety. In response to these concerns, IAEA Director-General Grossi plans to visit South Korea, New Zealand, and the Cook Islands to address the apprehensions surrounding the plan.

The UN nuclear agency’s endorsement of Japan’s plan to release treated radioactive wastewater from the Fukushima nuclear plant into the Pacific Ocean marks a significant development in the ongoing debate. While the IAEA’s assessment claims a negligible impact, opposition persists, with neighboring countries and local fishing organizations expressing safety concerns and apprehensions about reputational damage. The Japanese government vows to maintain transparency and provide scientific evidence to support the plan. The debate surrounding the release of Fukushima’s treated water continues to raise questions about the long-term consequences of such actions and the importance of international cooperation in addressing nuclear safety and environmental concerns.
