Korean experts are involved in a plan to dilute the treated water accumulated at TEPCO's Fukushima Daiichi Nuclear Power Plant to a concentration below the standard and release it into the sea. An inspection team consisting of Korean experts will visit the site on June 23 to inspect the storage status of treated water and the status of construction of facilities for discharge.

The Japan and South Korea agreed at a summit meeting held on May 7 to dispatch a South Korean inspection team to the site, and an inspection team of about 30 people visited the Japan on May 21.
