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). This website of the Federal Office for Radiation Protection (BfS) will therefore no longer be updated and displays the status as on 24 April 2017. You will find current information at the BGE: www.bge.de

Asse mine Inflow of water risen at main collecting point

At the main collecting point on the 658-m level, the inflow of uncontaminated salt water has slightly risen. The Asse-GmbH informed the Federal Office for Radiation Protection (BfS) and the Landesamt für Bergbau, Energie und Geologie (LBEG) on 27 May 2013 that the reporting threshold of 11,100 litres per day averaged over a period of one week, was exceeded. The threshold was specified by the Landesamt für Bergbau, Energie und Geologie. According to present knowledge, there are no immediate effects on the current operation or the mine's safety. The long-term average at this point has been 10,500 litres per day.

Radiation protection Operator removes radioactively contaminated brine in front of chamber 12

Radioactively contaminated brine accumulated over years in front of an emplacement chamber in the Asse mine the handling of which had not been clear is now being removed and processed further. The Federal Office for Radiation Protection (BfS) has initially pumped out altogether around 17 cubic metres of brine in front of chamber 12 on the 750-m level of the Asse mine and has the brine taken to special collecting containers in another part of the mine. The brine is to be further processed to salt concrete in the mine. The removal of the brine enables the next step in the retrieval of the waste from the Asse mine. Besides it makes emergency preparedness easier.

Asse mine Preliminary works for 3D-seismic test measurement at Asse have started

After the Regional Mining Authority has approved the performance of the measurements, preparations started for the 3D seismic test measurement between Remlingen and Wittmar. The receiving and excitation points are currently measured by members of the commissioned company and examined by a bomb disposal team. Subsequently the receiving devices (geophones) will be placed and wired. The actual measurements will probably begin on 20 March and will take about two weeks.

Asse mine Law governing the Asse mine (Lex Asse) is to speed up retrieval

Strong political support for an important step: The so-called Lex Asse creates legal provisions to speed up the retrieval of the nuclear waste from the Asse II mine. In the new Asse law, retrieval will now also be legally laid down as the decommissioning option to be pursued. The key points of the new law are explained in the 20th edition of the "Insights into the Asse Mine".

Asse mine Spiral drift in the Asse mine passable again

The entire so-called spiral drift in the Asse mine can be used again. Following a remediation taking about one year, works could be completed faster than expected. The remediation of the spiral drift serves the safety of the staff and is a prerequisite for a successful retrieval of the waste from the Asse mine.

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.
