Eleven experts from South Korea and other countries are expected to participate in the International Atomic Energy Agency (IAEA) verification team, which inspects the process of releasing contaminated water from the Fukushima nuclear power plant in Japan. The IAEA will finish discussions on the activity plan and scope of work of the verification team, and will officially announce the composition of the verification team soon. The Korean expert has been decided to be Dr. Kim Hongseok of the Korea Nuclear Safety Technology Center (KINS). Dr. Kim is acting as the representative of the United Nations Radiation Effects Science Committee in South Korea. In 2018, I was in charge of verifying the danger during the so-called “radon situation” when radon, which is a radioactive substance, was detected in beds and shocked. In 2009, he was one of the 100 largest scientists in the world selected by the Cambridge International Center for Personal Names (IBC). Dr. Kim was included in the verification team according to the government’s recommendation. The composition of the verification team is the unique authority of the IAEA. Participants are often selected according to a voluntarily constructed expert pool, but this time, the intention of the Korean government was reflected to a large extent. It is analyzed that the country is directly affected by the release of contaminated water. In addition to Dr. Kim, one expert will be dispatched from 11 related countries such as the United States, China, and France. Prior to this, in April this year, the Japanese government decided to release 1.25 million tons of radioactively contaminated water from the Fukushima nuclear power plant into the sea. The South Korean government has formed a pan-government TF (task force, working group) since 2018 to respond, but it could not prevent this. Immediately after the announcement of the release decision, the government strongly opposed the request for cooperation from the United States, and President Moon Jae-in embarked on a card to sue the International Tribunal for the Law of the Sea. However, the IAEA and the United States have maintained their position that “respecting Japan’s decisions, ocean releases will proceed transparently in accordance with IAEA standards.” Inside and outside the government, the predominant judgment was that it was practically difficult to respond by international law. In response to this, the government has turned to a strategy of actively participating in the verification of the IAEA dimension and a strategy of concentrating on transparent information disclosure requests by the composition of the Korea-Japan Council. As the IAEA has already officially decided that if Japan’s decision to release contaminated water into the ocean is made as planned, it will meet international treatment standards, so unless a serious defect is found during the verification process, the ocean release will be on schedule. It is likely to start in 2023. The government has argued that the Japanese government has not provided core information on the start of the release, the release period, the disposal method, the total amount of disposal, etc., but the Japanese side is keeping the position that “there is no fixed one yet”. ..
