Reliability and qualification of components: Modern202 Deliverable D3.6

This study summarizes the progress made by entities (implementers, regulators and scientific researchers) on a common multi-stage methodology for qualifying monitoring components of the measurement chain (sensor, connecting cable and/or wireless system/controller) at a Deep Geological Repository (DGR). It results from a multi-stage analysis including: i) the study of transferable experience gained from other industry fields, ii) the analysis of case studies operating in conditions close to those expected in repositories, iii) the initiatives for the development of a qualification process for selecting and testing the monitoring components and at last iv) the proposal for a global protocol appropriate to all monitoring contexts.
