A study on the wireless transmission monitoring for the geological disposal repository in France

In France, reversibility is recommended as an important philosophy for the long lived radioactive waste disposal by the government. ANDRA has been establishing the concept of reversible repository and its step-wise management. Monitoring is considered to play an important role so as to realize the step-wise management. However, it never be allowed that the monitoring system deteriorate the performance of the barrier of the repository. In this report, the concept of the wireless monitoring system, which contributes to monitoring in the reversible repository without any disturbance of the barrier, is presented. Its technical feasibility is also described on the basis of the experimental study.
