先進型原子炉システムの設計最適化や安全評価を支援する「AI支援型革新炉ライフサイクル最適化手法(ARKADIA)」の一部として、設計基準事象までの設計課題に適用する「ARKADIA-Design」の整備を進めてきた。本報では、今後の開発課題とともに、ARKADIA-Designにおける、炉心設計及び炉構造設計、並びに保全に関わる点検工程の最適化プロセスの実装状況と、最適化検討とともに個別評価におけるプラント挙動の解析に必要な複数の解析コードの連成解析技術の整備状況を報告する。

To assist conceptual studies of various reactor systems conducted by private sectors in nuclear power innovation, development of an innovative design system named ARKADIA (Advanced Reactor Knowledge- and AI-aided Design Integration Approach through the whole plant lifecycle) is undergoing. In this paper, focusing on the ARKADIA-Design, achievements in the development of optimization processes in the fields of the core design, the plant structure design, and the maintenance schedule planning, as major function of ARKADIA-Design, and numerical analysis methods to be used for the detailed analysis to confirm the plant performance after optimization are introduced at this point in time.
