2011年3月11日，日本东部发生里氏9级大地震，随后东京电力公司福岛第一核电站发生大规模海啸，并在1-3号机组引发了前所未有的堆芯熔化/严重事故。放射性物质的释放导致当地居民撤离，其中许多人仍然无法返回家园。
作为一个核专家小组，日本原子能协会成立了福岛第一核电站核事故调查委员会，从科学和技术角度调查和分析事故，以澄清根本原因，并提出建议。AESJ调查委员会的调查结果汇编为最终报告。
由史无前例的大地震/海啸引发的福岛第一核电站灾难性核事故的直接成因——海啸措施、严重事故管理、应急响应、事故恢复和缓解方面的不足——以及潜在因素——组织问题等。，已经澄清，并在以下方面提出了建议。
-核安全基础
-事故的直接因素
-组织方面
-共同项目（研发、国际合作、人力资源管理）
-事故后管理/事故恢复。
The Fukushima Daiichi Nuclear Accident: Final Report of the AESJ Investigation Committee
The Magnitude 9 Great East Japan Earthquake on March 11, 2011, followed by a massive tsunami struck TEPCO’s Fukushima Daiichi Nuclear Power Station and triggered an unprecedented core melt/severe accident in Units 1 – 3. The radioactivity release led to the evacuation of local residents, many of whom still have not been able to return to their homes.
As a group of nuclear experts, the Atomic Energy Society of Japan established the Investigation Committee on the Nuclear Accident at the Fukushima Daiichi Nuclear Power Station, to investigate and analyze the accident from scientific and technical perspectives for clarifying the underlying and fundamental causes, and to make recommendations. The results of the investigation by the AESJ Investigation Committee has been compiled herewith as the Final Report.
Direct contributing factors of the catastrophic nuclear incident at Fukushima Daiichi NPP initiated by an unprecedented massive earthquake/ tsunami – inadequacies in tsunami measures, severe accident management, emergency response, accident recovery and mitigations – and the underlying factors – organizational issues, etc., have been clarified and recommendations in the following areas have been made.
– Nuclear safety fundamentals
– Direct factors of the accident
– Organizational aspects
– Common items (R&D, International cooperation, human resources management)
– Post-accident management/recovery from the accident.
