Japan's Reports on Conditions at TEPCO's Fukushima Daiichi Nuclear Power Station
The Japanese Government has provided the IAEA with a report that
summarizes the events and highlights the progress related to recovery
operations at the Fukushima Daiichi Nuclear Power Station. The IAEA
provided its assessments, which are contained in full at the end of the
report.
The IAEA acknowledges the multiple initiatives including the groundwater bypass, sub-drains, land-side impermeable walls and the water proof pavement which have contributed to the steadily reduced volume of groundwater inflow into the buildings.
The IAEA notes the continuous progress that has been made in the investigation of damaged fuel and fuel debris inside the PCVs. The information gained from the investigation will help to plan for the safe decommissioning of the site. The IAEA also notes that, during the investigations, there was no attributable change in radiation levels at monitoring posts and dust-monitoring at the site boundaries of Fukushima Daiichi Nuclear Power Station.
The IAEA acknowledges that continued and significant efforts have been undertaken by the Japanese government, the prefecture and the concerned municipalities to implement decontamination in the SDA and ICSA. The IAEA encourages Japan to continue monitoring the air dose rate in the environment and to continue to implement remediation measures, as appropriate.
Based on the information provided by Japan, no significant changes were observed in the monitoring results for seawater, sediment and marine biota during the period covered by this report. The levels measured by Japan in the marine environment are low and relatively stable. For the purpose of public reassurance, the IAEA encourages continuation of sea area monitoring, particularly considering the ongoing authorized discharges of treated and monitored groundwater into the ocean.
The IAEA considers that the extensive data quality assurance programme helps to build confidence of the stakeholders in the accuracy and quality of the sea area monitoring data.
Based on the information provided by Japan, no significant changes were observed since the previous report. Measurements of caesium radionuclide levels in foodstuffs, together with appropriate regulatory action and public communication, including the publication of monitoring results, are helping to maintain confidence in the safety of the food supply. Food restrictions continue to be revised and updated as necessary in line with the results of food sampling and monitoring. This indicates the continued vigilance of the authorities in Japan and their commitment to protecting consumers and trade. Based on the information provided by the Japanese authorities, the situation with regard to the safety of food, fishery and agricultural production continues to remain stable.
Based on the information that has been made available, the Joint FAO/IAEA Division understands that measures to monitor and respond to issues regarding radionuclide contamination of food are appropriate, and that the food supply chain is controlled effectively by the relevant authorities.https://www.iaea.org/newscenter/news/japans-reports-on-conditions-at-tepcos-fukushima-daiichi-nuclear-power-station-22
