9.4. Management processes are necessary to establish the quality of data. The qualification of data should constitute a set of procedures that permit traceability and transparency of the data and their interpretation, when such data are to be used in regulatory decisions. Data used in a safety case may be derived from one of several origins:
- Data collected within the disposal facility project that is subject to the management system;
- Data collected as part of a research programme that is not subject to the management system;
- Data collected historically, which predate the existence of the management system;
- Information from the literature that reflects general knowledge, understanding or measurements, and which is not necessarily specifically associated with the disposal facility project under consideration.
