Japan's nuclear regulator Friday approved the release of treated radioactive water from the crippled Fukushima nuclear power plant, thus allowing the country to begin discharge of the waste into the sea this summer.

The plant's operator, Tokyo Electric Power Company Holdings Inc., received certification from the Nuclear Regulation Authority of Japan after the International Atomic Energy Agency (IAEA) approved Japan's water discharge plan through a comprehensive assessment, Tokyo-based Kyodo News reported.

Neighboring China has fiercely opposed the plan and on Friday imposed a ban on the import of seafood from Japan’s 10 regions.

However, the IAEA its two-year-long safety review report concluded the discharge of nuclear waste will have a “negligible” impact on people and the environment.

However, Beijing disagrees.

The report was submitted to Japanese Prime Minister Fumio Kishida early this week by IAEA chief Rafael Grossi.

“The IAEA conclusion is largely limited and incomplete and failed to respond to the international community’s concerns over Japan’s plan to dump nuclear-contaminated wastewater into the ocean,” said Wang Wenbin, a spokesman for China’s Foreign Ministry, Beijing-based Global Times reported.

Grossi, however, stressed that the report does not signify support for Japan's decision to discharge the nuclear-contaminated water into the ocean.

Wang said Grossi’s remarks that “one or two experts” of the IAEA team had concerns over the agency’s report on Japan’s nuclear waste, “once again prove the report was hastily released and failed to fully reflect views from experts who participated in the review.”

“When you see that the results are correct ... and nobody is lying to you, then maybe trust will be reconstructed,” Grossi told reporters in Tokyo today, referring to opposition from some IAEA experts over the release of nuclear waste, which Japan plans to begin this summer.

Participants from at least 11 countries were part of the team which prepared the IAEA report.

“China urges Japan not to take the report as the greenlight,” but suspend the dumping plan and dispose of the nuclear-contaminated wastewater in a responsible way, Wang added.

Grossi is now traveling to South Korea, New Zealand, and Cook Islands, which is the current chair of the Pacific Islands Forum, to "address concerns, hear views, clarify IAEA role" on Japan's nuclear waste, the IAEA chief said on Twitter.

Japan's water discharge plan, announced in April 2021, faced significant criticism from China, South Korea, North Korea, Taiwan, and international organizations, including the UN.

The US supported the proposal, following years of discussions on dealing with over 1 million tons of water stored at the Fukushima nuclear complex since the 2011 disaster.

Despite the pressure, Japan last month initiated the injection of seawater into a drainage tunnel at the damaged Fukushima Daiichi Nuclear Power Plant, marking the initial stage of releasing treated radioactive wastewater into the ocean.
