In the context of the preparatory safety assessments phase (PSA) of safety and feasibility case 1 (SFC1), the objective of the present report is to provide a first tentative definition of the reference scenario and reference case for a hypothetical geological repository of B&C waste in Boom Clay at the reference site Mol-Dessel. The main part of the reference scenario consists of a description of the reference evolution of the disposal system and its environment. The reference case can be considered the most simple, robust and defensible conceptual representation of the reference evolution. In this report, the description of the reference case is limited to the conceptual model description of the corresponding performance assessment model, which is iteratively developed. The validity of the conceptual model descriptions of processes taken into account in the reference case and their application domain were verified with key experts during a 4-day workshop held in October 2011.
