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

Setting up of drill rig in front of chamber 7 concluded

15. December 2011: The setting-up of the drill rig for the first drilling through the sealing structure of emplacement chamber 7 on the 750-m level has been concluded. Asse-GmbH staff and external experts are now checking to see whether all components have been installed and assembled correctly before the prescribed acceptances will take place.

Asse staff complete work area in front of emplacement chamber 7

14 October 2011: Staff of the Asse-GmbH set up the drilling device in front of emplacement chamber 7 and drilled a four-metre-deep hole into the sealing dam using a ten-centimetre-thick drilling device. The hole separates the waste from the residual mine. The so-called stand pipe was concreted into the borehole. The stand pipe is a massive steel pipe the preventer is fastened to later on..

The drilling device is set up in the work area in front of emplacement chamber 7

26 August 2011: With extreme care Asse staff took the drilling device to its future operational site in front of emplacement chamber 7. A Diesel driven forklift initially transported the drilling device into the steep inclining emplacement chamber 5. Then the device was lifted by a smaller forklift with electric drive and taken via the lock to its future operational site.

The decontaminable floor covering in front of emplacement chamber 7 has been laid - the measurement containers have been set up

22 July 2011: The decontaminable floor covering in front of emplacement chamber 7 on the 750-m level has been laid. The floor covering consists of plastic tiles whose joints are welded. This creates a smooth, easy-to-clean work surface. Thus it is ensured that possibly released radioactive substances cannot get into the ground.

Laying of the decontaminable floor covering in front of emplacement chamber 7 started

6 June 2011: This starts the setting-up of the devices. Only after the floor covering has been laid completely and has been approved by experts, can the actual setting-up begin. Now the measurement containers, the ventilation and filter technology and the tarpaulin-like separation can be built up. Later on the drilling area is to be separated from the residual mine through the radiation protection area.

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.
