Backfilling of roof clefts ceases due to supplier problems

Salt producer does not meet contractual obligation to supply

The backfilling of roof clefts to stabilise the Asse II mine has been interrupted because the company supplying the salt for the production of the special type of concrete does currently not meet its obligation to supply which has been ensured by contract. The company has agreed as to its next transport taking place on 27 July 2010.

The time until the salt supply will be resumed is being used for preparations in order to be able to immediately carry on with the backfilling of roof clefts. For example, drillings are carried out through which the special concrete is pumped into the roof cleft. Also the construction of sheeting walls continues which prevent the special concrete from escaping the areas to be backfilled.

The backfilling of roof clefts consists of filling up residual cavities between the roofs of the mining districts (cavity where no radioactive waste has been emplaced) and the salt backfill with a special type of concrete. This serves to stabilise the mine and is to reduce the risk of an increase in saline solution flowing into the 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.
