Description
Gegenstand der Erfindung ist eine Vorrichtung zum LagernThe invention relates to a device for storage
bestrahlter Brennelemente unterschiedlichen Abbrandes aus Hochtemperatur-Kernreaktoren, insbesondere zum Lagern hochabgebrannter Brennelemente aus dem Thorium-Hochtemperaturreaktor (THTR).irradiated fuel elements of different burnups from high-temperature nuclear reactors, especially for storing highly spent fuel elements from the thorium high-temperature reactor (THTR).
Abgebrannte Brennelemente von Leistungsreaktoren werden bis zur Wiederaufarbeitung des bestrahlten Brennstoffes bisher ausschließlich in Wasserbecken zwischengelagert. Während dieser Lagerzeit klingt die Radioaktivität der Spalt- und Aktivierungsprodukte ab. Das Wasser erfüllt dabei gleichzeitig die Funktionen der Kühlung der heißen Brennelemente und der Abschirmung der radioaktiven Strahlung.Spent fuel assemblies from power reactors are pending reprocessing of the irradiated fuel has so far only been temporarily stored in water basins. During this storage time, the radioactivity of the cleavage and activation products sounds away. The water simultaneously fulfills the functions of cooling the hot ones Fuel elements and the shielding of radioactive radiation.
Die Kühlung der Brennelemente ist notwendig, um die freigesetzte Nachwärme abzuführen, deren Größe vom Abbrand im Reaktor und von der bereits vergangenen Kühlzeit abhängt.The cooling of the fuel assemblies is necessary to absorb the residual heat that is released discharge, their size from the burn-up in the reactor and from the cooling time that has already passed depends.
Aus dem Kühlwasser wird die Wärme in außenliegenden Kühlern durch einen sekundären Kühlwasserkreislauf und einen Naßkühlturm an die Umgebung abgeführt. Aus den zur Verfügung stehenden geringen Aufwärmspannen resultieren relativ große Kühlwasserdurchsätze und große Kühlflächen. Die Zwischenlagerung abgebrannter Brennelemente aus Leistungsreaktoren in Wasserbecken hat daher den Nachteil, daß ein hoher Kühlwasserverbrauch auftritt, durch die Kühltürme eine Umweltbelästigung erfolgt und die Reinigung des Wassers sowie die Zwischen- und Endbehandlung der abgetrennten radioaktiven Abfälle kostspielig ist.The heat is transferred from the cooling water to external coolers a secondary cooling water circuit and a wet cooling tower discharged to the environment. The available short warm-up spans result in relatively large ones Cooling water flow rates and large cooling surfaces. The interim storage of spent fuel elements from power reactors in water basins therefore has the disadvantage that a high cooling water consumption occurs, through the cooling towers an environmental nuisance occurs and the cleaning of the Water as well as the intermediate and final treatment of the separated radioactive waste is costly.
Außerdem ist ein hoher Abdichtungsaufwand und somit Sicherheitsaufwand für die Wasserbecken erforderlich, da das Wasser durch nicht ganz vermeidbare Undichtigkeiten in den Brennelementumhüllungen radioaktiv kontaminiert wird und ferner auch die unvermeidliche Radiolyse des Beckenwassers beherrscht werden muß. Insgesamt ergeben sich für Wasserbecken sehr hohe Investitions- und Betriebskosten.In addition, there is a high expenditure on sealing and thus a high level of security Required for the water basin, as the water through not entirely avoidable leaks is radioactively contaminated in the fuel element casings and also the inevitable radiolysis of the pool water must be mastered. Overall result Very high investment and operating costs for water basins.
Insbesondere für die bestrahlten und abgebrannten Brennelemente des Thorium-Hochtemperaturreaktors (THTR), die aus Graphitkugeln mit darin enthaltenden kohlenstoffummantelten Thorium-Uranpartikeln bestehen, existieren bisher noch keine Vorrichtungen, die zuverlässig und auf einfache Weise eine Zwischenlagerung dieser Brennelemente bis zur endgültigen Aufarbeitung gestatten.In particular for the irradiated and spent fuel elements of the High-temperature thorium reactor (THTR) made from graphite spheres with contained therein carbon-coated thorium uranium particles do not exist yet Devices that reliably and easily provide temporary storage for these Allow fuel assemblies until final processing.
Es war daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Lagern bestrahlter bzw. abgebrannter Brennelemente aus Hochtemperatur-Kernreaktoren bis zu ihrer Wiederaufarbeitung zu schaffen, bei der eine zuverlässige Zwischenlagerung bis zur endgültigen Aufarbeitung auf einfache Weise ermöglicht ist.It was therefore an object of the present invention to provide a device for the storage of irradiated or spent fuel elements from high-temperature nuclear reactors to provide for their reprocessing, with which a reliable interim storage is made possible in a simple manner until the final work-up.
Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß die in verschlossenen Metallbehälter gefüllten und in Lagergestellen angeordneten Brennelemente in einer abgeschlossenen Kammer gelagert werden, deren Wände außen von einem Luftstrom im Naturzug bestrichen werden, der über Zuführungs- und Abführungskanäle an die Kammerwände herangeführt wird. Es ist vorteilhaft, als Kammer eine Betonkammer zu verwenden, jedoch können auch Stahl und andere Werkstoffe benutzt werden.This object was achieved according to the invention in that the in closed Metal containers filled and arranged in storage racks in a fuel element closed chamber, the walls of which are outside of an air stream in the Natural draft are coated, which via supply and discharge channels to the chamber walls is introduced. It is advantageous to use a concrete chamber as the chamber, however, steel and other materials can also be used.
Entgegen den bisherigen Vorstellungen, daß aus Sicherheits- und Abschirmungsgründen eine Wasserlagerung von abgebrannten Brennelementen unbedingt notwendig sei, wurde überraschenderweise gefunden, daß die bestrahlten und abgebrannten Brennelemente aus Hochtemperatur-Kernreaktoren bereits nach relativ kurzen Abkling-Zeiten, von z.B. einem Jahr, gefahrlos in Kammern trocken gelagert werden können, wenn sie erfindungsgemäß mit Luft im Naturzug gekühlt werden. Die Brennelemente werden dazu in Metallbehälter gefüllt und in einer Kammer in sogenannten Lagergestellen gelagert.Contrary to previous beliefs that for security and shielding reasons water storage of spent fuel elements was absolutely necessary Surprisingly found that the irradiated and spent fuel from high-temperature nuclear reactors already after relatively short decay times, from e.g. one year, can be stored safely in dry chambers if they are according to the invention be cooled with air in a natural draft. The fuel elements are placed in metal containers filled and stored in a chamber in so-called storage racks.
Diese Anordnung und die erhöhte Temperatur der Brennelemente bewirkt, daß die Luft innerhalb der Kammer im Naturzug selbsttätig angesaugt wird, an den Behältern entlangstreicht und die Wärme an die Kammerwände abgibt, die von außen ebenfalls im Naturzug gekühlt werden.This arrangement and the increased temperature of the fuel assemblies causes that the air inside the chamber is automatically sucked in in the natural draft, to the Brushes along the containers and emits the heat to the chamber walls, which come from the outside can also be cooled in a natural draft.
Eine Anlage zur Zwischenlagerung abgebrannter Brennelemente besteht vorteilhafterweise aus mehreren Kammern bzw. Lagerzellen, die nach außen und gegen die Bedienungs- und Aufenthaltsräume für das Personal nochmals mit dicken Betonwänden abgeschirmt werden. Die Brennelementbehälter werden durch ein sogenanntes Lagergestell, vorteilhafterweise ein Rohrgestell, in geometrisch sicherer Anordnung gehalten. Die Behälter bestehen vorzugsweise aus Stahlblech und sind mit einem federnden Deckel verschlossen.There is a facility for the interim storage of spent fuel elements advantageously from several chambers or storage cells, the outward and against the operating and common rooms for the staff again with thick concrete walls be shielded. The fuel element casks are stored in a so-called storage rack, advantageously a tubular frame, held in a geometrically secure arrangement. The containers are preferably made of sheet steel and have a resilient lid locked.
Besonders vorteilhaft ist es, die Fundamentplatte unter dem Lagergestell mit Luftführungsschächten zu versehen, so daß eine noch bessere Luftzuführung zu den Lagergestellen erfolgen kann, die ebenfalls als Luftführungskanäle dienen und einen optimalen Wärmeaustausch bewerkstelligen.It is particularly advantageous to place the foundation plate under the storage rack to be provided with air ducts, so that an even better air supply to the storage racks, which also serve as air ducts and achieve an optimal heat exchange.
Anhand der Abbildungen I und II wird in schematischer Darstellungsweise eine beispielhafte Ausgestaltung der erfindungemäßen Vorrichtung zum Lagern bestrahlter Brennelemente aus Hochtemperatur-Kernreaktoren dargestellt, wobei Abbildung I einen Querschnitt und Abbildung II einen Längsschnitt zeigt.Based on Figures I and II, a schematic representation an exemplary embodiment of the inventive device for storing irradiated Fuel assemblies from high-temperature nuclear reactors shown, Figure I being a Cross-section and Figure II shows a longitudinal section.
