JSFRの革新技術10項目について採否判断を行った結果をまとめた。高燃焼度燃料,安全性向上,コンパクト原子炉構造,冷却系2ループ化,ポンプ組込IHI,高信頼性SG,自然循環崩壊熱除去系,簡素化燃料取扱設備,SCCV,免震建屋の10項目すべてについて採用可能であることを確認した。

Key technologies for Japan Sodium-cooled Fast Reactor (JSFR) have been evaluated. The ten technologies: high burn-up fuel, safety enhancement, compact reactor vessel, two-loop cooling system using high chromium steel, integrated intermediate heat exchanger/pump component, reliable steam generator, natural circulation decay heat removal system, simplified fuel handling system, containment vessel made of steel plate reinforced concrete and advanced seismic isolation system have been confirmed to be feasible to be installed a conceptual design of demonstration JSFR to be ready for large scale demonstration experiments.
