Konrad mine
The pit Konrad (Schacht Konrad) is a former iron ore mine proposed as a deep geological repository for medium- and low level radioactive waste in the city Salzgitter in the Metropolitan region Hannover-Braunschweig-Göttingen-Wolfsburg in southeast Lower Saxony, Germany, located between Hildesheim and Braunschweig. It has two shafts: Konrad I and Konrad II. 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 shaft Konrad is the youngest of the former iron ore mines in this region. It has two shafts, of which Schacht Konrad I, is approximately 1232 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 The shaft Konrad 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
