We visited Onagawa NPP and discussed with the workers, for study of good practices at this plant, avoided severe accident, when the 3.11 earthquakes and tsunami disaster occurred. It was learned a part of background of the good practices, by discussion about organizational culture included in attitude for safety, philosophy of management, inheritance technology, and so on. It is important that we inform the knowledge leading safety culture analyzed from their experience to public, as professional engineer.

At radioactive waste management facilities in the Nuclear Science Research Institute, solid radioactive wastes are stored by using containers such as 200L drums and pallets to tier containers in 2 to 4 stacks in the height direction in waste storage facilities (Waste Storage Facility No.1, Waste Storage Facility No.2 and Waste Size Reduction and Storage Facility). On March 11, 2011, the Great East Japan Earthquake was happened, and some waste packages dropped from their pallets and large number of waste packages moved from their original position and inclined due to the influence of the earthquake in the waste storage facilities. There was no experience of rearrangement works to set those dropped and unbalanced waste packages in their original position and it was necessary to prepare detailed work procedures and progress for this task to prevent the occurrence of industrial accidents. Therefore, we prepared detailed work manual and repeatedly carried out mock-up test. And then, we started rearrangement work from April 2011 after confirmation of workers skill and adequacy of the work manual. Finally, all rearrangement works for stored waste packages took about four and half years and were completed in September 2015 without any accident and shutdown of storage function. This report summarizes the countermeasures to reduce exposure doses of workers and to prevent the occurrence of industrial accidents during the rearrangement works.

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.

The Great East Japan Earthquake hit on March 11, 2011. The Earthquake and following tsunami struck huge area. The Fukushima Daiichi Power Station run by Tokyo Electric Power Company lost power and reactor cooling failed due to an operative power generator. This presentation shows JAEA's activities such as an environmental emergency monitoring, evaluation personal exposure, decontamination and so on.
