The Japan government plans to dilute the treated water containing tritium and other radioactive substances that accumulate at the Fukushima Daiichi Nuclear Power Station to a concentration below the standard and release it into the sea. TEPCO is preparing to start releasing it by around this summer.

The governments of Japan and the ROK agreed at the summit meeting held on May 7 to dispatch a South Korean inspection team to the site. An inspection team consisting of about 30 people has been visiting the Japan for six days from 21 to 6.
