FBR開発を進めるにあたって、FBRの導入によりもたらされる様々な効果を多面的な視点から定量的に把握し、高価に見合う適切な研究開発投資規模を把握する必要がある。本研究は、上記の目的のために平成11年度までに構築したシステムの改良を行い、いわゆる投資対効果を評価するシステムを開発したものである。具体的な改良目的は、新エネルギーとFBR導入の効果を比較するためのサブルーチンの追加、特に新エネルギーに関する外部性を評価するロジックを追加、発電コスト試算のロジックを従来の年経費率方式から耐用年平均コスト方式への変更、データベース機能の検討、である。また、投資対効果評価システム自体もデータベース機能を待てるようにMicrosoft ACCESSにより再構築した。以上の改良の結果、従来よりもより汎用性のある投資対効果評価システムが構築でき、今後の応用に期待できるものと考えられる。

In order to promote the FDR development, it is necessary to see various benefits brought by introduction of FBR from multiple perspectives and have agood grasp of such benefits quantitatively and an adequate R&D investment scale which corresponds with them. In this study, the structured prototype in the previous study was improved to be able to perform cost-benefit analysis. An example of improvement made in the system is addition of subroutine used for comparison between new energy and benefits brought by introduction of FBR with special emphasis on addition of logic for analyzing externality about the new energy. Other improvement examples are modification of the Conventiona1 Year Expense Ratio method of power generation cost to Average Durable Year Cost method, addition of database function and turning input data into database, and reviewing idea on cost by the type of waste material and price of uranium. The cost-benefit analysis system was also restructured utilizing Microsoft ACCESS so that it should have a data base function. As the result of the improvement mentioned above, we expect that the improved cost-benefit analysis system will have higher generality than the system before; therefore, great deal of benefits brought by application of the system in the future is expected.
