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.

As a study on long-term safety of geological disposal of high-level waste (HLW) generated during reprocessing spent mixed oxide fuel in light water reactors (MOX-LWRs), two types of HLW are considered. One is HLW generated from MOX-LWR reprocessing and another is blended MOX-UO
HLW generated during reprocessing process whereby MOX fuels are diluted by UO fuels. Radionuclide migration analyses for those two HLWs are conducted, and commonalities and differences between two HLWs in the viewpoint of long-term safety are discussed.

The issue of high-level waste disposal is important for the sustainable use of nuclear energy. P&T technology of long-lived and highly radiotoxic MA is a key technology. The MA separation process, which separates MA from the high-level waste, is one of the essential technology for realizing the P&T technology. JAEA has been developing the SELECT process using the solvent extraction technique for the MA separation process. Target values for separation performance were 99% recovery rate based on radiotoxicity evaluation and 95% MA product purity from evaluation of the performance of transmutation system. The separation process was demonstrated by the test using genuine HLW. SELECT process consists of two steps. The second step for MA/RE separation requires 40 extraction stages for the target value, and there was a issue of introduction and operation costs. Therefore, we set a reasonable recovery rate based on the evaluation of the environmental impact of the disposal site. Based on the target value, quantitative evaluation was carried out using the PARC-MA code, and the number of extraction stages in the MA/RE separation process and the purity of the MA product were obtained. We believe that the configuration of a realistic simplified MA separation process has been clarified.
