Outline of Final Research Achievements |
Based on research about the history of decommissioning of Fast Breeder Reactor (FBR) in France and Germany, this study reveled the following points. It is shown that there was a conflict between French Atomic Energy Commission and Electricity of France for the decision-making across the decommissioning of SPX (FBR demonstration reactor) by interviews with French nuclear engineers as well as new documents. As for the abandon of German SNR-300 (FBR prototype reactor) development program, some technical problems which had precluded its critical state, was also a reason to cancel its project, in addition to the impact of Chernobyl nuclear disaster. Considering the Franco-German history of decommissioning of FBR, Japan will probably refer to French decommissioning technology for its Monju (FBR prototype reactor). But Japanese nuclear fuel cycle policy should be different from French policy, and it is now time to review it fundamentally.

Academic Significance and Societal Importance of the Research Achievements |
学術的意義は、既存研究では扱われていないフランスとドイツのFBR廃止措置の歴史についてインタビューや新資料を基にその詳細を明らかにしたことである。 社会的意義の第1点目は、仏独のFBR廃止措置が日本のFBR原型炉もんじゅの廃止措置に与える影響を分析したこと、第2点目は、日本のFBR開発に関して廃止措置を前提に検討することを提言したことである。2022年1月に、アメリカテラパワーとアメリカエネルギー省のFBR開発計画にJAEAなどが参加することが発表された。新規にFBRを開発するということは、将来的にFBRの廃止措置に至るということを本研究により実証的に示したことは時宜に適っていると考える。
