The NEA Integration Group for the Safety Case (IGSC) held its annual meeting on 8‑10 October 2019 to discuss its ongoing and future activities in relation to developing safety cases for geological disposal of radioactive waste.
The meeting featured two topical sessions. The first topical session on risk and uncertainty underlined the need to consider the perspectives of different stakeholders during the decision‑making process on risk and ethical uncertainties, since uncertainties will remain throughout the lifetime of a disposal system.
The second topical session on updating a safety case concluded that it is necessary to have a systematic and traceable methodology documenting safety evidence and data, as the main purpose for safety case updates is to demonstrate the compliance status of a disposal system to safety requirements.
