IAEA promotes nuclear safety in all nuclear facilities and activities, including decommissioning, waste management and environmental remediation. Key elements to promote nuclear safety:
development of safety standards (SS)
review and advisory services
experience to developing countries
Convention on Safety of Spent Fuel and Safety of Waste Management
Fundamental Safety Principles
Basic objectives, concepts and principles involved in ensuring protection and safety
Requirements – Legal, Technical, & Procedural Safety Imperatives
Elaborate on the basic objectives and concepts of SF-1 as they apply to a specific activity or facility – “Shall” statements
Guidance on Best Practice to Meet Requirements
“Should” statements
Safety Guides Safety Requirements Safety Fundamentals
Incident and Emergency Centre (IEC) activated in Full Response Mode Collect and analyse information and share it with the world Coordinate and provide international assistance to Japan and supply information to the public
The purpose of the Action Plan was to define a programme of work to strengthen the global nuclear safety framework The Action Plan covered 12 key areas of nuclear safety with a view to integrating the lessons learned from the Fukushima Daiichi Accident
Safety Assessments IAEA Peer Reviews Emergency Preparedness and Response Operating Organizations IAEA Safety Standards National Regulatory Bodies International Legal Framework Member States Embarking on Nuclear Power Capacity Building Communication Research & Development Protection from Ionizing Radiation

The main objective of the first mission was an initial review of the Roadmap and a review of several specific short-term issues and challenges. The objective of the second mission was more detailed and holistic review of the Roadmap and mid-term challenges including the review of agreed specific topics. The objective of the third, follow-up mission was review of current on-site status & strategic plans for decommissioning and review of the progress and plans in several specific technical and non-technical areas.

Final reports submitted to GoJ on 22 May 2013 and 12 February 2014 and published on: https://www.iaea.org/sites/default/files/final_report120214.pdf https://www.iaea.org/sites/default/files/missionreport220513.pdf
Decommissioning F-D NPP is a challenging task that requires significant resources and innovative technologies Japan developed its efforts towards decommissioning the plant promptly after accident and has achieved good progress in its strategy and plans, and allocated necessary resources GoJ and TEPCO evolved to a more proactive attitude to address the many difficulties at the site Situation is still complex and there are still some challenging issues to be resolved to achieve a long-term stable condition of the plant. Japan adopted well-oriented set of measures to deal with it

for D&D and review progress in specific areas:
safety culture, communication with public…
contaminated water, including rainwater, and efforts of communication
16
decommissioning at operational and at strategic levels
New D&D branch of TEPCO (FDEC) to clarify responsibilities for decommissioning 1F Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF) as a national authority to develop strategy for the decommissioning
18
Successful completion of spent fuel removal in U4 Improvement of systems to clean contaminated water New more robust tanks to store water Operation of underground bypass Clean-up of site, reducing radiological dose to workers

Final report submitted to GoJ on 23 January 2014 and published on: https://www.iaea.org/sites/default/files/final_report230114.pdf
Japan is allocating enormous resources to developing strategies and plans and implementing remediation. Japan has achieved good progress in remediation activities and has well considered the advice provided by previous mission in 2011. Good coordination of remediation with reconstruction and revitalisation efforts.
