Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
A METHOD OF PREPARING STOICHIOMETRIC URANIUM MONOCARBIDE FROM NONSTOICHIOMETRIC URANIUM CARBIDE WHICH COMPRISES ADDING TO NONSTOICHIOMETRIC URANIUM CARBIDE SELECTED FROM THE CLASS CONSISTING OF HYPER- AND HYPOSTOICHIOMETRIC URANIUM CARBIDE AN ALLOYING METAL HAVING A RELATIVELY LOW THERMAL NEUTRON ABSORPTION CROSS SECTION AND A AF VALUE FOR CARBIDE FORMATIN BETWEEN UC AND UC2 AND REACTING THE ADMIXTURE TO FORM STOICHIOMETRIC URANIUM MONOCARBIDE AND A COMPOSITION SELECTED FROM THE CLASS CONSISTINF OF METAL CARBIDE AND METAL-URANIUM ALLOY FORMED BY RESPECTIVE REACTION WITH INITIALLY PRESENT NONSTOICHIOMETRIC URANIUM CARBIDE SELECTED FROM THE CLASS CONSISTING OF HYPER- AND HYPOSTOICHIOMETRIC URANIUM CARBIDE, RESPECTIVELY.
Claim 2
Independent Claim
97 words
A METHOD OF PREPARING STOICHIOMETRIC URANIUM MONOCARBIDE FROM NONSTOICHIOMETRIC URANIUM CARBIDE WHICH COMPRISES ADDING TO NONSTOICHIOMETRIC URANIUM CARBIDE SELECTED FROM THE CLASS CONSISTING OF HYPER- AND HYPOSTOICHIOMETRIC URANIUM CARBIDE AN ALLOYING METAL HAVING A RELATIVELY LOW THERMAL NEUTRON ABSORPTION CROSS SECTION AND A AF VALUE FOR CARBIDE FORMATIN BETWEEN UC AND UC2 AND REACTING THE ADMIXTURE TO FORM STOICHIOMETRIC URANIUM MONOCARBIDE AND A COMPOSITION SELECTED FROM THE CLASS CONSISTINF OF METAL CARBIDE AND METAL-URANIUM ALLOY FORMED BY RESPECTIVE REACTION WITH INITIALLY PRESENT NONSTOICHIOMETRIC URANIUM CARBIDE SELECTED FROM THE CLASS CONSISTING OF HYPER- AND HYPOSTOICHIOMETRIC URANIUM CARBIDE, RESPECTIVELY.
Claim 3
Dependent Claim
119 words
A URANIUM CARBIDE NUCLEAR REACTOR FUEL ELEMENT HAVING A CARBURIZABLE METAL CLADDING STABILIZED AGAINST CARBURIZATION BY CARBON TRANSFER FROM THE FUEL MATERIAL WHICH COMPRISES, IN COMBINATION, A CARBON-STABLE NUCLEAR REACTOR FUEL MATERIAL CONSISTING ESSENTIALLY OF STOICHIOMETRIC URANIUM MONOCARBIDE CONTAINING A COMPOSITION SELECTED FROM THE CLASS CONSISTING OF METAL CARBIDE AND METAL-URANIUM ALLOY FORMED BY RESPECTIVE REACTION WITH INITIALLY PRESENT NONSTOICHIOMETRIC URANIUM CARBIDE SELECTED FROAM THE CLASS CONSISTINF OF HYPER- AND HYPOSTOICHIOMETRIC URANIUM CARBIDE, RESPECTIVELY, THE METAL PORTION OF SAID METAL CARBIDE AND METAL-URANIUM ALLOY BEING SELECTED FROM AN ALLOYING METAL HAVING A RELATIVELY LOW THERMAL NEUTRON ABSORPTION CROSS SECTION AND A AF VALUE FOR CARBIDE FORMATION BETWEEN UC AND UC2, AND A CARBURIZABLE METAL CLADDING FOR SAID FUEL MATERIAL.
