Experts from the Korea Institute of Nuclear Safety (KINS), dispatched to Japan’s Fukushima Daiichi Nuclear Power Plant by the International Atomic Energy Agency (IAEA), visited the nuclear power plant facility on the 20th and inspected the central monitoring and control room and seawater piping header.
Park Gu-yeon, First Deputy Director of the Office for Government Policy Coordination, said this at the daily briefing on Fukushima contaminated water held at the Seoul Government Complex on the morning of the 25th.
Deputy Director Park said, “Our experts confirmed the current status of related facilities at the central monitoring and control room, which monitors and controls overall emission facilities, and confirmed that the radiation monitor values of the transfer facilities are maintained at normal levels. “He explained.
In addition, Deputy Director Park said, “Experts visited the seawater pipe header and confirmed the installation locations of the seawater intake port and upstream water tank radiation monitors, where the radiation concentration of diluted seawater and contaminated water after dilution is measured in real time.”
The seawater pipe header is where contaminated water and seawater meet and are diluted during the discharge period, and where Tokyo Electric Power Company collects samples every day to analyze tritium concentration.
In addition, through a Q&A with Tokyo Electric Power Company officials, our experts confirmed that △ there were no unusual issues in the inspection of major facilities after the end of discharge, △ that Tokyo Electric Power Company collected and analyzed samples from the upstream water tank before the second discharge, and that samples were collected and analyzed within 3 km of the seawater pipe header. It was confirmed that samples from the sea area will be collected every day.
A video conference was also held on the 21st with the participation of our experts and IAEA headquarters and field office staff. Deputy Director Park said, “As a result of the facility inspection after the end of the first discharge, there were no unusual findings, and we confirmed that IAEA inspections are carried out in the same manner as during the discharge period even during the non-discharge period.”
In addition, experts visited the IAEA Fukushima field office on the 22nd and as a result of the facility inspection after the first discharge, which was discussed in a video conference on the 21st, TEPCO collected samples from the K4-C tank group, which is subject to the second discharge, in the presence of the IAEA on June 26th. Deputy Director Park said that it was confirmed that one sample was also sent to the IAEA laboratory for cross-verification and analyzed.
