Want to see at first hand how things look at 1,000 metres beneath the earth’s surface, and deeper? Let us take you on an interesting and informative journey into the inner workings of Konrad. We’ll show you what goes on underground, where the radioactive waste will be stored.

Microsite Konrad

Konrad Overview

With this additional internetsite the Federal Office for Radiation Protection will give you a more exemplified and animated view of the future Konrad repository in Salzgitter.




The Federal Office for Radiation Protection is continuously monitoring the environmental radioactivity in Germany. About 1.800 Probes distributed all over Germany are measuring the gamma dose rate (GDR)


Konrad RepositoryKonrad's suitability to host a repository

In a depth of 800 to 1,300 metres of the Konrad mine there are iron ore deposits where one intends to dispose of the radioactive waste. Compared with other iron ore mines, Konrad is exceptionally dry. The covering layer of clay rocks, which is 160 to 400 m thick, seals the mine against the groundwater near the surface and the Salzgitter branch canal.

Konrad RepositoryThe geological condition of Konrad

The iron ore deposit of the Konrad mine, where radioactive waste is to be disposed of, formed about 150 million years ago in the Jurassic period.

Konrad RepositoryRock mechanics and seismology

The Konrad site is located in a tectonically undisturbed zone in Germany. The last relevant tectonic movements in the vicinity of the site took place about five million years ago.

Radioactive wasteTransports to the Konrad repository

Up until now, there is no operable and licensed repository for radioactive waste available in Germany. Already today, however, waste has been stored in decentralised interim storage facilities. For the Federal Office for Radiation Protection (BfS) it is natural to examine possible risks emanating from the transports of radioactive waste to the Konrad repository and to have as much knowledge of them as possible – irrespective of the fact that the BfS does neither carry out nor license the transports.

Radioactive wasteRadioactivity and radiation

Radioactivity is a term for the property of certain atomic nuclei to transform themselves into other nuclei without external influence. During this process, energetic radiation (alpha, beta, gamma or neutron radiation) is emitted. There are both natural radionuclides and artificial radionuclides generated by nuclear processes.

Radioactive wasteWaste package quality control

To ensure safety, the radioactive waste is subjected to several examination procedures before it is disposed of. A combined control of conditioning (packaging in a manner meeting the requirements for disposal) and random sampling has proven their worth.

ConversionTime it takes to convert the Konrad mine to a repository

The construction and operation of the Konrad repository was licensed in 2002 by the Lower Saxon Environment Ministry, following a plan-approval procedure having lasted twenty years. On 26 March 2007 the licence for Konrad was also confirmed by the Federal Administrative Court.

Radioactive wasteOrigin of radioactive waste

According to the plan-approval decision, 303,000 cubic metres of radioactive waste with negligible heat generation (low-level and intermediate-level radioactive waste) can be disposed of in the Konrad mine. That is about 50 per cent of all German radioactive waste. It includes only about 1 per cent of the total activity, however.

Radioactive wasteConditioning and containers

Radioactive waste is treated and processed in a special way before it is accepted for disposal in a repository. The term for the treatment and packaging of the radioactive waste is conditioning. To safely package all types of radioactive waste with negligible heat generation and at the same time meet the waste acceptance requirements, various methods or facilities are available for conditioning, depending on the consistency, size and quality of the waste.

Asse II mine

The Asse II mine near Wolfenbüttel is an approximately 100-year-old potash and salt mine. Between 1967 and 1978 radioactive waste were storaged here. In 2009 the Federal Office for Radiation Protection (BfS) took over operatorship for the Asse II mine. The task of BfS is to retrieve the radioactive waste and to decommission the Asse mine.

Endlager Morsleben - Luftaufnahme

Morsleben Repository

The Bartensleben mine in Morsleben served to mine potash and rock salt before it became a repository for radioactive waste in 1971. Until 1998, waste from nuclear power plants from the GDR and, later on, also from the Federal Republic of Germany was disposed of here. The Federal Office for Radiation Protection has now also applied for the decommissioning of the repository.
