Description

Die Erfindung betrifft ein Betonschutzgehäuse zur Aufnahme und Lagerung eines mit abgebrannten Kernreaktorbrennelementen beladenen, transport- und lagergeeigneten Brennelementlagerbehälters, wobei die lichten Maße des Betonschutzgehäuses etwas größer als die Außenabmessungen des Brennelementbehälters sind und wobei im unteren Bereich des Betonschutzgehäuses mindestens eine Zuluftöffnung und am höchsten Punkt des Betonschutzgehäuses eine Abluftöffnung angeordnet sind, die von einer mit Abstand zum Betonschutzgehäuse angeordneten Abdeckung überdacht ist.The invention relates to a concrete protective housing for receiving and storing a fuel element storage container loaded with spent nuclear reactor fuel elements, suitable for transport and storage, the clear dimensions of the concrete protective housing being somewhat larger than the external dimensions of the fuel element container and wherein at least one supply air opening and at the highest point of the in the lower area of the concrete protective housing Concrete protective housing an exhaust air opening are arranged, which is covered by a cover arranged at a distance from the concrete protective housing.

Bei den Bemühungen, Brennelementbehälter im Freien zwischenzulagern, wurde bereits vorgeschlagen, die Brennelementbehälter in Silobehälter aus Beton oder Stahlbeton einzubringen. Diese ein Betonschutzgehäuse für jeweils einen Brennelementbehälter bildenden Silobehälter können verschiedene Ausbildung aufweisen. Bei einem nicht vorveröffentlichten Vorschlag zur Ausbildung eines Schutzbehälters zur Aufnahme von Brennelementbehältern weist der Schutzbehälter seitliche Zuluftkanäle am unteren Mantelrand und seitliche Abluftkanäle im Bereich des oberen Mantelrandes unterhalb des Deckels auf (Patentanmeldung P 30 17 767.4). Durch die Anordnung dieser Zuluft- und Abluftkanäle wird innerhalb des Betonschutzgehäuses eine natürliche Konvektion bewirkt, die zur Abfuhr der Nachzerfallswärme dient.In the effort to temporarily store the fuel element containers outdoors, it has already been proposed to insert the fuel element containers into silo containers made of concrete or reinforced concrete. These silo containers, which form a concrete protective housing for each fuel element container, can have different designs. In a not previously published proposal for the formation of a protective container for receiving fuel element containers, the protective container has lateral supply air ducts on the lower edge of the casing and lateral exhaust air ducts in the region of the upper casing edge below the cover (patent application P 30 17 767.4). The arrangement of these supply air and extract air ducts results in natural convection within the concrete protective housing, which is used to dissipate the heat of decay.

Es ist ersichtlich, daß besonders für die oberen Abluftkanäle bzw. Abluftöffnungen Maßnahmen getroffen werden müssen, die das Eindringen von Regenwasser verhindern. Es ist daher naheliegend, die Abluftöffnungen abzudecken. Wird eine zentrale Abluftöffnung am höchsten Punkt des Betonschutzgehäuses vorgesehen, ist es zweckmäßig, im Abstand zum Betonschutzgehäuse eine dachförmige Abdeckung über der Abluftöffnung anzuordnen.It can be seen that measures must be taken especially for the upper exhaust air ducts or exhaust air openings to prevent the ingress of rainwater. It is therefore obvious to cover the exhaust air openings. If a central exhaust air opening is provided at the highest point of the concrete protective housing, it is expedient to arrange a roof-shaped cover at a distance from the concrete protective housing above the exhaust air opening.

Der Erfindung liegt die Aufgabe zugrunde, ein Betonschutzgehäuse der eingangs beschriebenen Art derart auszugestalten, daß ein verbesserter Schutz des Betonschutzgehäuses gegen Eindringen von Wasser und Schnee erzielt wird.The invention has for its object to provide a concrete protective housing of the type described in such a way that improved protection of the concrete protective housing against the ingress of water and snow is achieved.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Abluftöff- nung von senkrecht auf dem Betonschutzgehäuse befestigten Blechen, Streifen oder dergleichen umgrenzt ist, die mit geringem Abstand zur Abdeckung enden.The object is inventively achieved in that the voltage of A bluftöff- perpendicularly fixed on the concrete protective casing sheet, strip or the like, is delimited, which end at a small distance to the cover.

Die dachförmige Abdeckung überspannt die am obersten Punkt des Beton-. schutzgehäuses angeordnete Abluftöffnung. Durch die erfindungsgemäße Anordnung von senkrechten Blechen um die Abluftöffnung wird ein labyrinthförmiges Durchströmen des entweichenden Luftstromes erreicht. Die Kombination des Abdeckungsdaches mit den senkrechten Schutzblechen ergibt einen erhöhten Schlagregenschutz.The roof-shaped cover spans the top of the concrete. Protective housing arranged exhaust air opening. A labyrinth-like flow of the escaping air flow is achieved by the arrangement according to the invention of vertical sheets around the exhaust air opening. The combination of the cover roof with the vertical mudguards results in increased protection against driving rain.

Eine vorteilhafte Ausgestaltung der Erfindung wird im Kennzeichen des Anspruches 2 angeführt. Die abfallende Neigung der dachförmigen Abdeckung zu den Seiten ergibt mit den senkrechten Blechen auch bei widrigen Wetterverhältnissen und seitlich aufprallendem Regen einen guten Schlagregenschutz.An advantageous embodiment of the invention is set forth in the characterizing part of claim 2. The sloping inclination of the roof-shaped cover to the sides provides good protection against driving rain with the vertical sheets, even in adverse weather conditions and rain falling on the side.

Anhand der Zeichnung wird nachstehend ein Ausführungsbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

Das Betonschutzgehäuse besteht aus einem palettenartig ausgebildeten Fußteil 3, einem darauf aufgesetzten zylindrischen Betonschutzmantel 4 und einem auf dem Betonschutzmantel 4 liegenden zylindrischen Deckel 5.The concrete protective housing consists of a base part 3 in the form of a pallet, a cylindrical concrete protective jacket 4 placed thereon and a cylindrical cover 5 lying on the concrete protective jacket 4.

Das Fußteil 3 besteht aus einer quadratischen Bodenplatte 6, an deren Ecken jeweils ein Fuß 7 angeordnet ist, so daß das Fußteil 3 als unterfahrbare Palette ausgebildet ist. Der zylinderförmige Betonschutzmantel 4 ist auf das Fußteil 3 aufgesetzt und durch hier nicht gezeigte, geeignete Zentriervorrichtungen zum Fußteil 3 ausgerichtet. In dem Betonschutzmantel können hier nicht gezeigte axiale Bohrungen angeordnet sein. In diese Bohrungen wird Neutronenschutzmaterial eingebracht, das beispielsweise aus Kunststoffstäben bestehen kann.The foot part 3 consists of a square base plate 6, at the corners of which a foot 7 is arranged, so that the foot part 3 is designed as a pallet that can be driven under. The cylindrical concrete protective jacket 4 is placed on the foot part 3 and aligned with the foot part 3 by suitable centering devices (not shown here). Axial bores (not shown) can be arranged in the concrete protective jacket. Neutron protection material, which can consist of plastic rods, for example, is introduced into these holes.

Der Betonschutzmantel 4 weist an seinem unteren Ende Ausnehmungen 9 auf, die als Zuluftkanäle dienen. Der auf dem Betonschutzmantel 4 liegende Deckel 5 weist im Zentrum eine Abluftöffnung 11 auf. Diese Abluftöffnung 11 ist von senkrechten Blechen 12 umgrenzt, die am Deckel 5 des Betonschutzgehäuses befestigt sind. Über der Abluftöffnung 11 ist eine dachförmige Abdeckung 13 angeordnet, die auf vier senkrechten Stützen 14 am Betonschutzgehäuse befestigt ist. Die dachförmige Abdeckung 13 hat eine von der Mitte zu den Seiten fallende Neigung und ist in der projizierten Fläche größer als die Abluftöffnung 11. Zwischen den Stützen 14 sind halbhohe' Spritzbleche 16 angeordnet.The concrete protective jacket 4 has recesses 9 at its lower end, which serve as supply air ducts. The one on the concrete protective jacket 4 lying cover 5 has an exhaust air opening 11 in the center. This exhaust air opening 11 is delimited by vertical metal sheets 12 which are fastened to the cover 5 of the concrete protective housing. A roof-shaped cover 13 is arranged above the exhaust air opening 11 and is fastened to the concrete protective housing on four vertical supports 14. The roof-shaped cover 13 has a slope falling from the center to the sides and is larger in the projected area than the exhaust air opening 11. Between the supports 14, half-high 'splash plates 16 are arranged.

Auf der Bodenplatte 6 des Fußteiles 3 ist ein hier strichpunktiert dargestellter Brennelementbehälter 15 aufrechtstehend angeordnet.On the base plate 6 of the foot part 3, a fuel element container 15, shown here in broken lines, is arranged upright.

Bei Anlieferung des Brennelementbehälters 15 im Zwischenlager wird der Brennelementbehälter 15 auf die Bodenplatte 6 des Fußteiles 3 gestellt. Anschließend wird der-Betonschutzmantel 4 auf das Fußteil 3 über den'Brennelementbehälter 15 gestülpt. Als letztes wird der Deckel 5 auf das obere freie Ende des Betonschutzmantels 4 aufgesetzt.When the fuel assembly 15 is delivered to the intermediate storage facility, the fuel assembly 15 is placed on the base plate 6 of the foot part 3. The concrete protective jacket 4 is then placed over the base part 3 over the fuel element container 15. Finally, the cover 5 is placed on the upper free end of the concrete protective jacket 4.

Durch die Hachzerfallswärme der Kernreaktorbrennelemente wird die Luft im Betonschutzgehäuse 3, 4, 5 erwärmt. Die Warmluft tritt über die Abluftöffnung 11 aus, Frischluft tritt durch die im unteren Bereich des Betonschutzgehäuses angeordneten Zuluftöffnungen 9 ein. Es tritt ein Kamineffekt auf. Diese Naturzugbelüftung dient zur Abfuhr der Nachzerfallswärme. Der entweichende Luftstrom aus der Abluftöffnung 11 wird von der dachförmigen Abdeckung 13 zur Seite und über die umgrenzenden Blechstreifen 12 gezwungen. Der Luftstrom entweicht labyrinthförmig.The air in the concrete protective housing 3, 4, 5 is heated by the decay heat of the nuclear reactor fuel elements. The warm air exits through the exhaust air opening 11, fresh air enters through the supply air openings 9 arranged in the lower region of the concrete protective housing. There is a chimney effect. This natural draft ventilation serves to dissipate the heat of decay. The escaping air flow from the exhaust air opening 11 is forced to the side by the roof-shaped cover 13 and over the surrounding sheet metal strips 12. The air flow escapes like a labyrinth.

Seitlich einfallender Schlagregen kann aufgrund der labyrinthförmigen Abdeckung der Abluftöffnung 11 nicht in diese eindringen.Driving rain falling from the side cannot penetrate into the exhaust air opening 11 due to the labyrinth-shaped covering.
