Senior members of the International Atomic Energy Agency are in Japan to discuss a planned release of treated water from the troubled Fukushima Daiichi nuclear power plant.
The team led by Lydie Evrard, the head of the IAEA's Department of Nuclear Safety and Security, met Japanese officials at the industry ministry on Tuesday.
Evrard called the meeting the first of the team's mission that will continue for years to support Japan. She added that the two sides will also have such discussions during and after the release.
Evrard called on the Japanese side to provide information on how to proceed with the plan, to ensure safety and transparency.
Japan's government plans to dilute treated water containing radioactive tritium to levels below national standards, and start releasing it in about two years.
The plant's operator, Tokyo Electric Power Company, has announced plans to build an undersea tunnel to a point about 1 kilometer from the plant and release the treated water there.
The IAEA officials are scheduled to visit the plant in the northeastern prefecture of Fukushima on Wednesday.
They're also expected to send a group of investigators to the plant this year to report on the safety of the release after talks with government and utility officials.
