Basic Philosophy for Earthquake Safety Assurance beyond Design Basis Events

Sat. Nov 25, 2023 3:40 PM - 5:10 PM G417 (PACIFICO Yokohama North, 4F)

Chairperson: Yasuki Ohtori (Tokyo City University)

福島第一原子力発電所事故の教訓である設計基準を超えた事象（BDBE）に対する基本的考え方についていろいろと議論されている。そのひとつに、従来の設計をBDBEに対する安全評価や安全性向上の領域まで広げた拡大設計対象領域の概念や、最近では、リスク情報活用（risk-informed）と性能規定（Performance-based）を特徴とする原子力安全確保の考え方の枠組みの中で地震安全確保しようとする考え方も提案されている。本セッションでは、これらのBDBEに対する考え方について、その課題や方向性について議論する。
