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 had provided its assessments, which is contained in full at the end of the report.
The IAEA assessment refers to?the final report of the International Decommissioning Peer Review Mission to Japan that took place from 9 to 17 February 2015 was published on 14 May 2015. The scope of this Mission -- and the follow-up expert visit on 17-21 April 2015 -- covered the majority of issues pertaining to current and forecast conditions, radiation worker protection, and actions taken by the Japanese government. A copy of the final report is available?here.??
At the time of writing this report, nearly all of the stored water, already treated for the removal of cesium, had been treated for the removal of strontium-90. Approximately 70 per cent of the stored water has also been treated for the removal of the other radionuclides as well, while the remaining 30 per cent would still require additional treatment. The assessment?notes?that the water thus treated would still contain tritium and storage of treated contaminated water containing tritium in above ground tanks is a temporary measure while TEPCO develops a more sustainable solution. The IAEA is aware of the recent news carried by the media on discovered water leaking and will seek additional information from counterparts in Japan to continue assessment of developments.
The IAEA assessment further looks at the sea area radioactivity monitoring results and other related information that has been made available.? The IAEA considers here that the situation in the marine environment is stable but should continue to be monitored.
Finally, the assessment indicates that the Agency considers that systems are in place and are being implemented that prevent food and agricultural products with levels of caesium radionuclides in excess of the national regulatory limits from entering the food supply chain.
