Asse mine BfS starts exploration works for a new Asse shaft

To be able to recover the radioactive waste from the Asse repository safely, the Federal Office for Radiation Protection (BfS) plans the construction of a new shaft. Planning works for the new shaft run parallel to the preparations of the trial phase (fact finding) for retrieving the radioactive waste. Based on the available geological knowledge the BfS has determined a possible site for the new shaft. Prior to starting the exploration drillings, the BfS needs to get the required licences from the federal state of Lower Saxony.

Decommissioning Lower Saxon federal state collecting depot plans to have contaminated brine processed in Brunswick by way of trial

To open chamber 12 in the scope of the fact finding (trial phase) around 80 cubic metres of brine need to be removed. According to legal regulations it is incumbent upon the federal state of Lower Saxony to take the contaminated brines into the federal state collecting depot. The Lower Saxon Environment Ministry commissions companies to deal with this task. The Federal Office for Radiation Protection does not have any influence on this form of contract with third parties.

Decommissioning Time schedule for drilling into Asse

The Federal Office for Radiation Protection (BfS) has set up a comprehensive time schedule for drilling into the first emplacement chamber of the Asse repository. This schedule takes into consideration the time that is necessary for complying with the licensing requirements of the Lower Saxon Environment Ministry (NMU). On 21 April 2011 the NMU issued its licence including 32 requirements. The BfS needs to fulfil these requirements before the first emplacement chamber of the Asse mine may be drilled into. "On the basis of these requirements, we have set up a time schedule consisting of about 850 work steps", a BfS spokesman said. If everything goes according to plan, drilling works can start at the beginning of November.

Asse mine 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.

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.
