性能評価は、異なるサイトや設計オプションの適用性や優劣の評価で重要な役割を果たすことが期待される。本論文では、その役割を果たすための、次世代性能評価への要求と関連する研究開発課題について論じる。

In the Japanese deep geological disposal programme, the goals of applications of performance assessments (PA) have changed considerably from original generic feasibility demonstrations to site-specific comparison of options that may result from the current call for volunteer communities to host a repository. PA will play a key role to support highly sensitive decisions at main milestones, particular associated with ranking different site and design options. The paper will discuss requirements for next generation PA to play the role and associated R&D needs.
