The Konrad mine (Schacht Konrad) is a former
History
The iron ore deposits have been mined since the start of the industrialization in the Salzgitter area. The first activities began in 1867. The Konrad mine is the youngest of the former iron ore mines in this region. It has two shafts, of which Schacht Konrad I, is approximately 1,232 meters and Schacht Konrad II is around 999 meters deep. The mining operation on Konrad lasted from 1961 to 1976. During this period, a total of 6.7 million tonnes of iron ore were retrieved.
Authorization for radioactive waste disposal
Konrad mine is an unusually dry iron ore mine. Since this is one of the criteria for a deep final repository for radioactive waste, the studies on the possibility of a disposal site were started in 1975. The Physikalisch-Technische Bundesanstalt (PTB) started the plannings procedure on 31 August 1982. The Bundesamt für Strahlenschutz, the Ministry of Environment of Lower Saxony and the Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe discussed the issue between September 1992 and March 1993. On 22 May 2002 the license for the final deep geological storage of medium- and low level radioactive waste was approved.
Several complaints against the license were filled at the Oberverwaltungsgericht
The license approves the storage of up to 0.000303 km3 (or 303,000 m3) of low- and medium level radioactive waste. After the initial phase of final storage to clear the backlog of 88,000 m3 waste in other locations the expected traffic is 10 road freight vehicles and one train of 20 freight wagons per week.[2]
By the end of 2007 around 945

Conversion
The establishment of the technical installations for the disposal and storage chambers started. The conversion has taken a number of years and was due to be complete in 2027, though this date will now not be met. Storage is scheduled to start the early 2030s.[4] Clustered storage chambers form a storage depot. In total, up to nine storage depots are projected on the existing main soles on 800, 850, 1000, 1100, 1200 and 1300 m depth. The storage chambers are created with a diameter of about 40 m2 with a bottom width of about 7 meters and a height of about 6 meters. Its length should be - depending on the geological and mining technical conditions - 100 to 1000 meters.
After the storage of the radioactive containers, the sectional shafts will be closed with concrete for the permanent storage of the nuclear waste.
