To guarantee operational safety during the operational phase of a final repository, monitoring systems are indispensable. At the same time, long-term safety analysis performed prior to the construction and operation, can be verified by the measurements obtained during the operational phase.
With respect to the specific aspects of monitoring nuclear waste repositories, optical fibre sensors offer unique advantages: small size, remote distributed measurements along a single optical fibre and for some types the potential of renewable sensors if emplaced in small tubes.
The renewable aspect inherently covers some of the long-term aspects. Within the scope of this project, three types of sensors will be developed and/or qualified: renewable distributed temperature sensing, renewable distributed dosimetry and hydrogen sensing.
