Abstract

Subterranean storage cavities for nuclear fuel are constructed from concrete which is radiation proof. The cavities are constructed in chalk or gypsum deposits. The walls of the cavity are first lined with a radiation shield before the concrete is applied. The stores can be used for fuel which is being held for reprocessing. It can also be used as the final store for spent fuel. The cavities can occur in coal mining operations or in rock salt deposits. The concrete should absorb and decelerate fast neutrons and gamma-radiation.

Patentbeschreibung. Patent description.

zeigen des Schutzes der Umwelt vor Atomstrahlen ist die Entsorgung der Kraftwerke von abgebrannten Brennelementen zu einem wichtigen Politikum geworden.show the protection of the environment from nuclear radiation is the disposal spent fuel power plants has become an important political issue.

Zur Zeit werden die abgebrannten Brennelemente in stillgelegten Salzbergwerken endgelagert, und es ist beabsichtigt, noch nicht erschlossene Salzstöcke für deren Aufnahme zu erschließen.At the moment the spent fuel elements are in disused salt mines and it is intended to use as yet undeveloped salt domes for their Tap into recording.

Pur Kernbrennstoffe, die wiederaufbereitat werden sollen und für iederaufbereitungsanlagen, sind andere Plätze vorgesehen.Pure nuclear fuels that are to be reprocessed and for reprocessing plants, other places are provided.

Gegenstand der Erfindung ist das unterirdische Bauwerk für die Aufnahme der Kompaktlagerung, der Zwischenlagerung, der Wiederaufbereitungsanlage, aber auch der Endlagerung, in einem Kreidesediment oder in einem Gipssteinlager. The subject of the invention is the underground structure for the recording compact storage, interim storage, reprocessing plants, but also final disposal, in a chalk sediment or in a gypsum store.

Diese geologischen Vorkommen wirken strahlenabweisend durch den im Bergwasser und beim Gipsstein im Hydratwasser befindlichen Wasserstoff.These geological occurrences have a radiation-repellent effect due to the im Mountain water and hydrogen in the hydration water of gypsum stone.

Unter Kreide werden die sogenannten Schreibkreide und die Tuffkreide verstanden; geologisch : Senon, Obersenon,Naastrichtien.Chalk includes the so-called writing chalk and tuff chalk Understood; geological: Senon, Obersenon, Naastrichtien.

Die Sedimente sind standfest. Das Ausräumen ist mit Ausräumvar vorrichtungen, wie sie im Steinkohlenbergwerk üblich sind,möglich.The sediments are stable. The clearing is possible with clearing devices, as they are common in the coal mine, possible.

Zu ; Unterirdische Bauwerke für Zwecke der Lagerung und Nutzung von Kernbrennstoffen.To ; Underground structures for storage and use of Nuclear fuel.

Bei den Gipssteinvorkommen ist das Dihydrat (CaSO4.2iI20) dem Anhydrit (CaSO4) vorzuziehen.In the gypsum deposits, the dihydrate (CaSO4.2iI20) is the anhydrite (CaSO4) is preferable.

Unter den genannten geologischen Vorkommen befindet sich häufig ein Steinsalzsockel.Among the geological occurrences mentioned there is often one Rock salt base.

Als Beton wird ein Strahlenschutzbeton verwendet, das ist ein Schwerbeton, der Gamma-Strahlen und schnelle Neutronen in erwünschter Weise abbremst.A radiation protection concrete is used as concrete, which is a heavy concrete, which slows down gamma rays and fast neutrons in the desired manner.

Alpha-Teilchen und Beta-Teilchen haben kürzere Reichweiten in Luft reichen die Alpha-Teilchen nur wenige Zentimeter und die Beta-Teilchen bis etwa 8 m.Alpha particles and beta particles have shorter ranges in air the alpha particles only reach a few centimeters and the beta particles up to about 8 m.

Eine zusätzliche Schutzmaßnahme ist die Abschirmung der Strahlung - für jede Strahlenart besonders - durch Wände aus geeignetem Material vor dem Beton.An additional protective measure is the shielding of the radiation - especially for each type of radiation - through walls made of suitable material in front of the concrete.
