[en] This document is the DORec (file of technical options for recoverability) as foreseen by a previous deliberation, and is based on the studies undertaken by the ANDRA for a preliminary draft of the future Cigeo waste storage facility. After a recall of some important definitions (storage and warehousing, reversibility and recoverability), the indication of the DORec scope, and of the scope of the DORec studies, this file presents the Cigeo project (wastes to be stored, project phasing, description of the storage centre). It describes the recoverability approach adopted for Cigeo: objectives, fundamental aspects, robustness of containers, of disposal cells and of equipment left in these cells, control, withdrawal equipment, adaptation to deconstruction and to reactivation of cell closing works, protective arrangements, exploitation arrangements, periodic re-assessment of recoverability. It finally presents some withdrawal scenarios.
