The International Atomic Energy Agency gave an essential endorsement Tuesday of a controversial plan by Japan to release treated water from the crippled Fukushima No. 1 nuclear power plant into the Pacific, paving the way for it to be released this summer.

Ahead of his meeting with Prime Minister Fumio Kishida, IAEA Director General Rafael Grossi presented the organization¡¯s safety assessment report, which concluded that the discharge of the treated water into the sea is ¡°consistent with relevant international safety standards.¡±

¡°If the Japanese government decides to proceed with the plan, (it) would have a negligible impact on the environment, meaning water, fish and sediment,¡± Grossi said at a news conference following his meeting with Kishida.

Grossi said that the IAEA will continue to monitor the situation if the plan to discharge the treated water moves forward.

¡°The IAEA will be here permanently, reviewing, monitoring, assessing, these activities for decades to come,¡± he added.

Kishida, meanwhile, reiterated that he would not allow the treated water to be discharged if there are signs it would have a harmful impact on human health and the environment.

¡°Japan will continue to provide explanations to the Japanese people and the international community in a sincere manner, based on scientific evidence and with high levels of transparency,¡± the prime minister said.

On Wednesday, Grossi will travel to Iwaki, Fukushima Prefecture, where he will meet with local residents before touring the Fukushima No.1 plant, which experienced a triple meltdown following the March 2011 earthquake-triggered tsunami. The IAEA chief will then visit South Korea on Friday to talk with government officials, Yonhap News reported Tuesday.

In early 2021, Japan announced its basic policy for discharging the water, which will be treated through a filtration system known as the Advanced Liquid Processing System (ALPS). The high-tech treatment machines are able to remove most radionuclides except tritium. As such, water laced with tritium will be released into the sea, and Japan requested that the IAEA review the safety of the plan.

¡°It should be noted that the total amount of tritium ... to be released each year in the discharge of ALPS-treated water will be well below the amount of these radionuclides produced by natural processes each year, such as interaction of cosmic rays with gases in the upper atmosphere,¡± the IAEA report said.

Over the past two years, the IAEA has conducted a safety review to see how Japan¡¯s plan measures up against international safety standards.

But the plan to release more than 1 million cubic meters of treated water currently being stored at the Fukushima plant into the surrounding ocean has angered Japan¡¯s neighbors.
