Since the nuclear accident of Fukushima Daiichi Nuclear Power Stations (Fukushima nuclear accident) which occurred in the Great East Japan Earthquake on March 11th 2011, a great deal of information on the accident and the response has been disseminated from the government, utilities and related research institutes. To put the information into good account in the radiation control in the affected area, decommissioning the reactors, environmental remediation, recurrence prevention, etc., the appropriate conservation and succession of the information which is referred to as archives hereinafter, is important. The activities of archives on the information and knowledge are essential as assets to be shared and utilized not only domestically but also internationally. On the other hand, the conservation of the information on radioactive waste management until final disposal has been also considered to be important. In this presentation, the archival activities on the Fukushima nuclear accident are reported with a focus on the Fukushima Archive system developed by the JAEA. On the basis of the archival activities investigated, lessons learned are discussed toward the information management on radioactive waste management.
