Tokyo Electric Power Company (TEPCO) is conducting a comprehensive review to identify all the possible risks that might have an impact outside the site boundary of the Fukushima Daiichi Nuclear Power Plant, according to information recently submitted by Japan to the IAEA. The comprehensive review process follows the detection of a puddle of highly contaminated water at the large carry-in entrance rooftop of the Unit 2 Reactor Building on 24 February, which is a potential source of inlets to the drainage system.
In an an interim report released on 9 April, TEPCO also made available the details of the reviewing process, which aim to identify risks that might involve leakage of water or scattering of dust. After risks are identified, they will be classified into five categories: 1. Need further examination, 2. Countermeasures necessary to be taken, 3. Countermeasures in practice, 4. Follow-up observation (after implementing countermeasures) in practice, 5. No need for additional measures.
As for the risks classified as "Countermeasures necessary to be taken", suitable countermeasures will be considered and their implementation will start subsequently. In addition, risks will be regularly reviewed and the result of the review announced.
For further information about the detail of this reviewing process, please see this document.

Radioactivity in water near the Fukushima Daiichi Nuclear Power Plant has remained low and stable from 8 to 14 March 2015, according to the regular update and sea area monitoring results provided to the IAEA by Japan's Nuclear Regulation Authority (NRA).
In addition, Tokyo Electric Power Company (TEPCO) has recently provided the following information:
- Schedule of Main Targeted Events at Fukushima Daiichi Nuclear Power Station.
- A short technical note regarding contaminated water purification.
- A survey report regarding fish and shell fish measurements.
- A statement indicating that 90% of the stored contaminated water is scheduled to be treated by the end of May 2015.
TEPCO also released a statement on its website regarding the fourth anniversary of the earthquake and tsunami.

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 has provided its assessments which is contained in full at the end of the report.
First, this assessment refers to the third International Decommissioning Peer Review Mission to Japan that took place from 9 to 17 February 2015. The objective of the Mission was to provide an independent review of the activities associated with revisions to the planning and implementation of the Fukushima Daiichi Nuclear Power Plant decommissioning. A Preliminary Summary Report from the Mission is available here.
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.
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.
Finally, the Agency welcomes the Japanese Government's issuance of this information to the IAEA Member States and the public, detailing the current status of the recovery operations. The IAEA will continue to share such valuable information as it is provided.
