Reversibility and safety of radioactive waste disposal in geological formation (Disposal reversibility and safety: which interactions?); Reversibilite et surete du stockage des dechets radioactifs en formation geologique (Reversibilite et surete du stockage. Quelles interactions?)

Addressing the issues of reversibility and safety of radioactive waste disposal in geological formation, and the interaction between reversibility and safety, this contribution discusses how uncertainties and risks are managed within the frame of a safety approach when safety relies on site and parcel characteristics and on design and organisation measures. Besides design and technological choices, various monitoring actions are planned, as well as means to limit impacts on workers and to intervene during exploitation if necessary. Reversibility and safety are also taken into account in immediate protection and safety requirements, and in the protection of future generations and of their environment.
