Am 25. April 2017 sind die Betreiberaufgaben für die Schachtanlage Asse, das Endlager Konrad und Morsleben auf die Bundesgesellschaft für Endlagerung mbH (BGE) übertragen worden. Diese Seite des Bundesamtes für Strahlenschutz (BfS) wird daher nicht mehr aktualisiert und zeigt den Stand vom 24. April 2017. Aktuelle Informationen erhalten Sie bei der BGE: www.bge.de

Again changes in influent saline solutions detected in Asse

The inflow of saline solution into the Asse II mine has again changed. This time, a location in front of mining district 9 on the 750-m level is affected. A mining district is a mine opening where salt has been mined formerly. This mining district is backfilled with Sorel concrete, no radioactive waste is stored there. According to information provided by Asse GmbH, the volume of the influent saline solution has increased from previously 30 litres per day to now about 110 litres per day at the location in front of mining district 9. An increase in the saline solution volume does not have any safety-relevant effects on this level. What is noticeable is that a different chemical composition has been found in these new influent saline solutions. This indicates that the inflow occurs via a path that is different from previous ones. The influent saline solution has probably seeped through the Sorel concrete. Asse GmbH is observing the development. The Federal Office for Radiation Protection will continue to inform the public.

Three weeks ago, Asse GmbH had registered fluctuations in the inflow of saline solutions on the 658-m level. After some days, this inflow of saline solutions had again decreased to the former level of about 10.4 cubic metres per day. The total volume of influent saline solutions continues to range around 12 cubic metres per day.

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.
