Title: Development of a Theoretical Monitoring System Design for a HLW Repository Based on the 'MoDeRn Monitoring Workflow' (A Case Study) - 12044

Abstract

In this paper, a generic German disposal concept in rock salt is used as an example to discuss the design of a repository monitoring system. The approach used is based on a generic structured approach to monitoring - the MoDeRn Monitoring Workflow - which is being developed and tested as part of an on-going European Commission Seventh Framework project. As a first step in the study, the requirements on the monitoring program were identified through consideration of the national context, including regulatory guidelines, host rock properties and waste to be disposed of. These are stated as general monitoring objectives. An analysis of the German safety concept for safe confinement of the radioactive waste allows these general objectives to be converted into specific sub-objectives, and for the sub-objectives to be related to specific monitoring processes and parameters. The safety concept identified the key safety components, each of them having specific associated safety functions. The safety functions can be related to the list of features, events and processes (FEPs) that contains all processes related to the future repository evolution. By screening the FEP list, all processes that potentially can affect the safety functions have been identified. In a next step the parametersmore » that would be affected by the individual processes were determined, leading to a preliminary list of parameters to be monitored. By evaluating available techniques and monitoring equipment, this preliminary list was investigated with respect to its technical feasibility at the intended locations. Prior to final system selection, potential impacts of the monitoring system on safety or other measurements are evaluated. To avoid potential pathways for fluids that may compromise the integrity of a barrier, considerations on the application of wireless data transmission systems and techniques for autonomous, long-term power supply were given.
