CEAと原子力機構は両者ともに実証炉の建設計画を有している。CEAはプール型炉のASTRID、原子力機構はループ型炉のJSFRを炉型として選択しており、本研究では両概念の相互分析を行い両者ともに成立性があり目標を達成しうることを確認した。また、協力項目として設計方針、機器開発、設計・解析手法等広範囲の項目を抽出した。

CEA and JAEA intend to develop prototype or demonstration (proto/demo) of sodium-cooled fast reactors within these two decades. Common final goals of their respective programs are SFR commercialization. The target of commercialized SFR for both parties is basically consistent with the Generation IV goals. Due to industrial backgrounds and feedback of past/existing reactor experiences, ASTRID and JSFR have selected pool and loop configurations respectively. CEA and JAEA have cross-analyzed both pool and loop concepts (ASTRID and demonstration JSFR). The analysis results showed that both concepts are technologically feasible and meet design goals. From the view point of collaboration, the present analysis has identified a wide range of collaborative items, in several fields: design principles (ex. design target, design standard), development on components and systems, development on parts of components, devices, or sub-systems, design methods, simulation tools, etc.
