Micro-seismic incident in the Asse overburden

On 28 April 2011, staff of the Asse-GmbH registered a clicking noise in working area 3 on the 490-m level, which could be well perceived acoustically. There is no need to report this so-called micro-seismic incident.

The incident occurred above the working area 3 of the 490-m level, in the southern overburden in a depth of about 432 m, at the border Rötanhydrit/Oberer Buntsandstein. It is in the area where a micro-seismic incident accumulation (cluster) has developed since January 2011.

So-called micro-seismic incidents occur repeatedly in old, insufficiently backfilled mines with extensive mine workings and were also registered in the past in the Asse mine. When such incidents happen, the tension breaks and as a result, cracks form in the rock.

Transfer of operator responsibilities

On 25 April 2017, the operator responsibilities for the Asse II mine as well as the Konrad and Morsleben repositories were transferred to the Federal Company for Radioactive Waste Disposal (Bundesgesellschaft für Endlagerung mbH, BGE). Previously, the responsibility for the projects was with the Federal Office for Radiation Protection (BfS). The foundations for the change of operatorship are laid down in the "Act on the Realignment of the Organisational Structures in the Field of Radioactive Waste Disposal", which became effective on 30 July 2016. The BfS focusses on the federal tasks of radiation protection, for example in the field of defence against nuclear hazards, medical research, mobile communication, UV protection or the measuring networks for environmental radioactivity.
