The present paper describes the current technology of uranium recovery from seawater by using radiation-induced graft-adsorbent and the utilization scenario of collected uranium from the viewpoint of long-term perspective of nuclear energy demand in Japan. The several thousand tons of uranium will be required in the latter half of 21st century in Japan, even if the plutonium is practically used in fast breeder reactors (FBRs). This demand of uranium can be supplied by the uranium recovered from seawater if the recovery cost is reasonable. In conclusion, the utilization of uranium from seawater will be able to play an essential role of providing enough time to develop safe and economical FBRs.

Requirements for databases are verification, validation and completeness. In the case of nuclear data, the verification stands on accuracy with uncertainty coming from differential experimental data. The validation does on benchmark tests with integral experimental data. The completeness is also necessary for targets, incident energy, reaction channels, etc. In this presentation, the direction of nuclear data as a database is considered. The future direction of nuclear data is introduced philosophically as well as history of nuclear data development, perspective of nuclear data, and requests.
