Acoustic-Seismic Monitoring of an Underground Final Repository - a Measurement Project — •Jürgen Altmann — Experimentelle Physik III, TU Dortmund

When spent fuel from nuclear power plants is deposited without reprocessing, the produced plutonium - which could be used for nuclear weapons - is still contained in it. Thus, safeguards of the International Atomic Energy Agency (IAEA) are needed for final repositories to detect potential access, during and after the emplacement phase. To find out if acoustic and seismic methods can be used to detect undeclared activities in an underground repository in salt, the German Support Programme for the IAEA has tasked us to do measurements in the exploratory mine in Gorleben, a potential site. To gain the source properties we record sound and vibration at several positions underground and at the surface while various mining activities are carried out singly and in parallel. The evaluations will investigate source detection, localisation and recognition.
