IAEA International Fact Finding Expert Mission of the Fukushima Dai-ichi NPP Accident Following the Great East Japan Earthquake and Tsunami

Report to the IAEA Member States

Tokyo, Fukushima Dai-ichi NPP, Fukushima Dai-ni NPP, and Tokai Dai-ni NPP, Japan

24 May - 2 June 2011

By agreement with the Government of Japan, the International Atomic Energy Agency

conducted a preliminary mission to find facts and identify initial lessons to be learned from

the accident at Fukushima Dai-ichi and share this information across the world nuclear

community. To this end, a team of experts undertook this Fact Finding Mission from 24 May

to 2 June 2011. The results of the Mission will be reported to the IAEA Ministerial

Conference on Nuclear Safety at IAEA headquarters in Vienna on 20 24 June 2011.

During the IAEA Mission, the team of nuclear experts received excellent cooperation from all

parties, receiving information from many relevant Japanese ministries, nuclear regulators and

operators. The Mission also visited three affected nuclear power plants (NPP) — Tokai Dai-

ni, Fukushima Dai-ni and Dai-ichi — to gain an appreciation of the status of the plants and

the scale of the damage. The facility visits allowed the experts to talk to the operator staff as

well as to view the on-going restoration and remediation work.

The Mission gathered evidence and undertook a preliminary assessment and has developed

preliminary conclusions as well as lessons to be learned. These preliminary conclusions and

lessons have been shared and discussed with Japanese experts and officials. They fall broadly

under the three specialist areas of external hazards, severe accident management and

emergency preparedness. They are of relevance to the Japanese nuclear community, the IAEA

and the worldwide nuclear community to learn lessons to improve nuclear safety.

The IAEA Mission urges the international nuclear community to consider the following 15

conclusions and 16 lessons in order to take advantage of the unique opportunity created by the

Fukushima accident to seek to learn and improve worldwide nuclear safety.
