Three Korean experts dispatched for the second time return to Korea
“Focus on the period when no discharge occurred”
Regarding the results of the second dispatch of Korean experts related to the discharge of contaminated water from the Fukushima nuclear power plant on the 25th, the government said, “There were no unusual findings as a result of the facility inspection after the end of the first discharge, and even during the non-discharge period, the inspection by the International Atomic Energy Agency (IAEA) was the same as the discharge period. “We have confirmed that it has come true,” he said.
Park Gu-yeon, First Deputy Director of the Office for Government Policy Coordination, said at a daily briefing on the discharge of Fukushima contaminated water held at the Seoul Government Complex this morning, “This visit will focus on checking the activities of the IAEA and TEPCO during the period when no discharge occurred and the status of preparations for the second discharge. “It went on,” he said.
According to Deputy Director Park, three experts from the Korea Institute of Nuclear Energy (KINS) were dispatched to Japan from the 19th to the 23rd to inspect the facilities at the discharge site. In addition, after holding a video conference with the IAEA, we visited the field office and inspected it.
Deputy Director Park explained that they first visited the Fukushima nuclear power plant facility on the 20th to check the status of facilities such as the central monitoring and control room and seawater piping header after the completion of the first discharge, and the installation location of radiation monitors at the seawater intake port and upstream water tank.
“Through Q&A with Tokyo Electric Power Company officials, there were no unusual issues when inspecting major facilities after the end of discharge, and Tokyo Electric Power Corporation collected and analyzed samples from the upstream water tank before the second discharge, and inspected the seawater pipe header and within 3km of the water. “We confirmed that samples will be collected every day.”
Through a video conference involving IAEA headquarters and field office staff, it was said, “There were no unusual findings as a result of the facility inspection after the end of the first discharge, and it was confirmed that IAEA inspections were carried out in the same manner as during the discharge period even during the non-discharge period.”
During the visit to the IAEA Fukushima field office that followed the video conference, he explained, “We reconfirmed the results of the facility inspection after the first discharge that was discussed in the video conference.”
Meanwhile, Deputy Director Park said, “If this value is less than 1, there is no risk to health,” regarding the “sum of notified concentration ratios” of 29 nuclides in the analysis results of contaminated water from the K4-C tank group announced by Tokyo Electric Power Company, which was found to be 0.21 to 0.25. He said, “Rather than whether radionuclides were detected, the standard should be whether the total concentration ratio notified exceeded 1.”
He added, “In addition, the contaminated water stored in the K4-C tank group is in a state before being diluted with seawater,” adding, “In the process of being mixed with hundreds of times more seawater and released, the concentration of radioactive nuclei becomes much lower.”
