Es ist bekannt, Brennstoffelemente aus Uranmetall und -legierungen, umhüllt mit einer gegenüber dem Kühlmitte! korrosionsbeständigen Hülse, in Kernreaktoren zu verwenden. Diese Brennstoffelemente haben jedoch schwerwiegende Nachteile. Einerseits ist die Betriebstempeiratur im Brennstoff durch die Alpha1-Beta-Transformation bei 660° C begrenzt. Wenn diese Temperatur überschritten wird, kommt es infolge der Dichteunterschiede der Alpha- und Beta-Phase zu sehr starken inneren Spannungen, die ein Aufreißen der Uranstäbe und meistens auch der Hülsen zur Folge haben, Dabei kann das Kühlmittel ungehindert mit dem Uran reagieren, wodurch sich das Brennstoffelement so stark verformt, daß es sich in vielen Fällen nur noch mit großer Mühe aus dem Kühlkanal entfernen läßt. Andererseits lassen Formänderungen orthorhombisch kristallisierenden Alpha-Urans sich bei Temperaturweohsel und Neutronenbestrahlung nur schwer vermeiden, insbesondere wenn in dem Metall eine Textur vorliegt.It is known, fuel elements made of uranium metal and alloys, encased with a facing the cooling medium! corrosion-resistant sleeve, to be used in nuclear reactors. However, these fuel elements have serious disadvantages. On the one hand, the operating temperature in the fuel is limited by the alpha 1- beta transformation at 660 ° C. If this temperature is exceeded, the differences in density between the alpha and beta phases lead to very strong internal tensions, which cause the uranium rods and usually the sleeves to tear the fuel element is deformed so much that in many cases it can only be removed from the cooling duct with great difficulty. On the other hand, changes in shape of orthorhombically crystallizing alpha uranium can only be avoided with difficulty in the event of temperature fluctuations and neutron irradiation, in particular if the metal has a texture.
Wesentlich günstigere Korrosionseigensehaften — insbesondere gegenüber heißem Wasser — haben Brennelemente, die Uranoxyd als Brennstoff enthalten. Das Kristallgitter des Uranoxyds ist bis zum Schmelzpunkt von, 2850° C stabil. Es treten deshalb die beim Uranmetall genannten Schwierigkeiten nicht auf. Dagegen ist die Wärmeleitfähigkeit von Uranoxyd wesentlich schlechter als die des Metalls, wodurch sich Stäbe aus Uranoxyd mit einem Durchmesser von 5 bis 10 mm während des Betriebes im Reaktor sehr stark erhitzen und unter Umständen diese Schmelztemperatur des Oxyds in ihrem Zentrum erreichen. Wenn bei einem mit solchen Brennstoffelementen ausgerüsteten Reaktor plötzlich die Kühlung ausfällt, so muß man, selbst wenn er sofort abgeschaltet wird, damit rechnen, daß sich die Brennstoffelemente infolge des Temperaturausgleicbes an der Oberfläche auf 1000 bis 1800° C erwärmen, wodurch die Korrosion des Hülsenmaterials mit dem Kühlmittel in verstärktem Maße einsetzt und die Brennelemente im allgemeinen zerstört werden. Bei Verwendung von natürlichem Uran macht sich die niedrige Dichte von etwa 10,0 g/cm3 des gesinterten. Uranoxyds sehr nachteilig bemerkbar, und außerdem bedingt die schlechte Wärmeleitfähigkeit des Uran,-oxyds dünne Stäbe als Brennstoffelemente. Folgerichtig nimmt der prozentuale Anteil des Hülsenmaterials wesentlich zu, und die Neutronenökonomie wird immer ungünstiger.Fuel elements that contain uranium oxide as fuel have significantly more favorable corrosion properties - especially compared to hot water. The crystal lattice of uranium oxide is stable up to the melting point of 2850 ° C. The difficulties mentioned with uranium metal therefore do not arise. On the other hand, the thermal conductivity of uranium oxide is much worse than that of metal, which means that rods made of uranium oxide with a diameter of 5 to 10 mm heat up very strongly in the reactor during operation and under certain circumstances reach this melting temperature of the oxide in their center. If the cooling of a reactor equipped with such fuel elements suddenly fails, even if it is switched off immediately, it must be expected that the fuel elements will heat up to 1000 to 1800 ° C as a result of the temperature equilibrium on the surface, which causes corrosion of the sleeve material begins with the coolant to an increased extent and the fuel assemblies are generally destroyed. When using natural uranium, the low density of about 10.0 g / cm 3 of the sintered one makes up for it. Uranium oxide is very disadvantageous, and in addition the poor thermal conductivity of uranium oxide causes thin rods as fuel elements. Consequently, the percentage of the sleeve material increases significantly, and the neutron economy becomes more and more unfavorable.
Auch Brennelemente aus Uranmonocarbid sind für gasgekühite Kernreaktoren bereits vorgeschlagen worden. Das Uranmonocarbid bat gegenüber dem Uranmetall den Vorteil, daß sein Kristallgitter bis zum Schmelzpunkt von 2300° C stabil bleibt undFuel elements made from uranium monocarbide have also already been proposed for gas-cooled nuclear reactors been. The uranium monocarbide had the advantage over the uranium metal that its crystal lattice was up to remains stable at the melting point of 2300 ° C and

wegen seiner kubisch flächenzentrierten Struktur weitgehend gegenüber Temperaturwechsel und Bestrahlung durch Neutronen stabil bleibt. Außerdem ist die Wärmeleitfähigkeit des Urancarbids wesentlich besser als z. B. die des Oxyds. Ein wesentlicher Nachteil des Uranmonocarbids ist jedoch seine sehr schlechte Korrosionsbeständigkeit gegenüber heißem Wasser, wodurch seither die Verwendung dieses Brennstoffes auf gasgekühlte Reaktoren beschränkt blieb. Zum Teil kann die schlechte Korrosionsbeständigkeit auch auf einen geringen Anteil· Uranmonocarbid zurückzuführen sein, in dem der Kohlenstoff salzartig gebunden ist. Das Dicarbid ist sogar ausgesprochen wasserzersetzlieh und bildet Acethylen.due to its face-centered cubic structure, it is largely resistant to temperature changes and irradiation remains stable by neutrons. In addition, the thermal conductivity of uranium carbide is essential better than z. B. that of the oxide. However, a major disadvantage of uranium monocarbide is its very poor corrosion resistance to hot water, which has since stopped using this Fuel remained limited to gas-cooled reactors. In part, the poor corrosion resistance can also be attributed to a small proportion of uranium monocarbide, in which the carbon is bound in a salty manner. The dicarbide is even extremely water-decomposing and forms acetylene.
Es wurde daher schon vorgeschlagen (R. Kieffer, Planseebericfate, Aprill 1957), Urainmonocarbid durch Legieren mit Carbiden der IV. bis VI. Gruppe des Periodischen Systems chemisch zu stabilisieren. Dieses Verfahren hat jedoch den Nachteil, daß verhältnismäßig große Mengen an fremden Carbiden zugesetzt werden müssen, wodurch sich die Konzentration des Spaltstoffes, sehr erniedrigt - und die Neutronenökonomie verschlechtert. Für solche Brennelemente kann deshalb nur ein Brennstoff, der mit dem Isotop U-235 oder einem anderen Spaltstoff angereichert ist, verwandt werden. Der Verwendung von natürlichem Uranmonocarbid in legierter Form für diese Brennstoffelemente stehen die bei der dadurch notwendigen Vergrößerung des Reaktor-Cores auftretenden Schwierigkeiten entgegen.It has therefore already been proposed (R. Kieffer, Planseebericfate, Aprill 1957), urine monocarbide through Alloying with carbides of the IV. To VI. Chemically stabilize group of the periodic table. However, this method has the disadvantage that relatively large amounts of foreign carbides must be added, whereby the concentration of the fissile material, very low - and the Neutron economy deteriorates. For such fuel assemblies, therefore, only a fuel that contains enriched with the isotope U-235 or another fissile substance. Of use of natural uranium monocarbide in alloyed form for these fuel elements necessary enlargement of the reactor core against occurring difficulties.
Bei den Brennstoffelementen gemäß der Erfindung ist zwischen der Hülse und dem Formkörper eine auf dem letzteren festhaftende, vorzugsweise dünne und gegen Wasser korrosionsbeständige Schutzschicht aus Carbiden bzw.
