The Gorleben salt dome is a proposed deep geological repository in a salt dome in Gorleben in the Lüchow-Dannenberg district in the far north-east of Lower Saxony for low-, medium- and high-level radioactive waste. ==Site selection== At the end of 1973 the search began for a final salt dome storage. The plan was a repository for all types of radioactive waste in a salt dome. 24 salt domes were considered. The federal government asked the company KEWA (Kernbrennstoff-Wiederaufarbeitungs-Gesellschaft) to search for a location. On July 1, 1975 the KEWA proposed three sites in Lower Saxony for further investigation: the salt domes Lutterloh, Lichtenhorst and Wahn. The location Gorleben is not advantageous in this category.〔Lüttig G. et al.: Bericht der Arbeitsgruppe Barrieren.- In: Niedersächsisches Umweltministerium (Hrsg.): Internationales Endlagerhearing, 21.-23. September 1993, Braunschweig.〕 The investigation of the sites began with drilling holes. In November 1976 the Lower Saxony cabinet called for the Federal Government to examine the three sites, so they could designate a location. In February 1977 the Lower Saxony cabinet designated finally the Gorleben salt dome as a single location for the repository and waste disposal center. The choice of Gorleben was the work of a project group which investigated 140 salt domes within a few months. Of these 140 salt domes only four were proposed: Lichtenhorst, Wahn, Maria Glück (Höfer) and Gorleben. Of these, Gorleben was chosen. The selection criteria were among others, land use, population density, radiation and repository geology. Geoscientific arguments played only a small role. For example, the salt dome Höfer (Maria Glück) is too small for a repository but reached the last round of selection. The ultimate decision for Gorleben according to the former Lower Saxony Prime Minister Ernst Albrecht was mainly for structural reasons for the economic development of the zone.〔Albrecht, E.:Interview mit dem niedersächsischen Ministerpräsidenten Ernst Albrecht über Atomstrom, Wiederaufarbeitung und Entsorgung.- Bonner Energie-Report, 4. Jg, Nr. 10 vom 6. Juni 1983, S. 18-21, Bonn.〕 1.5 billion Euro's of research has been conducted in the period 1979-2000 at Gorleben.〔(Where Should Germany Store Its Nuclear Waste? )〕 On hindsight it became clear that the original and methodologically correct approach, to investigate three potentially suitable salt domes in parallel and a comparative assessment of the results were abandoned by the choice for Gorleben. Security-oriented geoscientific arguments were ignored in the evaluation of Gorleben.〔Albrecht, I. et al.: Studie zur Entwicklung von Grundlagen für ein Verfahren zur Auswahl von Endlagerstandorten und Beurteilung ihrer Langzeitsicherheit, Abschlussbericht, im Auftrag des Niedersächsischen Umweltministeriums, November 1994, Hannover〕 The lack of transparency and accountability for the decision for Gorleben is still one of the reasons why the opposition to the location is so vehement. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gorleben salt dome」の詳細全文を読む スポンサード リンク
