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.

press release Federal Office for Radiation Protection implements new radiation protection rules for Asse

The Federal Office for Radiation Protection (BfS) has developed the nuclear law boundary conditions for the safe operation of Asse up to decommissioning, has made essential modifications to the operating procedure and thus implemented basic radiation protection requirements. This was necessary as the state of the facility was not in compliance with the stipulations of the Atomic Energy Act and the Radiation Protection Ordinance. "With this step essential deficiencies that had been the key cause for the change of operator were remedied," BfS President Wolfram König said on Thursday in Salzgitter.

press release Start of Asse health monitoring

The Federal Office for Radiation Protection (BfS) has started to review the radiation exposure to all former and current staff members of the Asse repository for radioactive waste. “The purpose of this health monitoring is to find out whether the cancer and leukaemia cases of former Asse staff members are associated with their occupational radiation exposure,” BfS spokesman Werner Nording said.

press release Federal Office for Radiation Protection backfills area of Asse that is no longer used with concrete

Today, the Federal Office for Radiation Protection (BfS) starts backfilling an area of Asse where no radioactive waste is stored and which is no longer used. Solely cavities below the emplacement chambers and in a depth of 850 m are backfilled with a special type of concrete (so-called Sorel concrete). The objective is to fill up open cavities. The licences required for these works have been granted. These works do not compromise any of the decommissioning options currently being examined.

press release Federal Office for Radiation Protection secures drums in chamber 7 on the 725-m level

The Federal Office for Radiation Protection (BfS) concluded the works to secure emplacement chamber 7 on the 725-m level in the Asse repository. To prevent a possible damage to the drums due to pieces of rock falling from the roof, BfS had drums stored in the chamber at first covered with salt grit (crudely ground salt). A milling tool was then used on this salt surface which removed loosened pieces of rock from the chamber roof.

press release Danger of a piece of rock falling in chamber on the 725-m level - waste will be covered with salt grit

Within the scope of an inspection of the Asse II repository on 27 April 2009, the Federal Office for Radiation Protection (BfS) found several locations with imbricated sluffing at the roof of emplacement chamber 7 on the 725-m level immediately above some emplaced drums. Chamber 7 is an emplacement chamber in the repository mine which is still open. There are a few drums in the chamber which have only partially been embedded in salt grit.

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.
