Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
46 words
A URANIUM CARBIDE NUCLEAR REACTOR FUEL ELEMENT HAVING A CARBURIZABLE METAL CLADDING STABILIZED AGAINST CARBURIZATION BY CARBON TRANSFER FROM THE FUEL MATERIAL PRESENT, WHICH COMPRISES, IN COMBINATION, A CARBONSTABLE REACTOR FUEL MATERIAL CONSISTING ESSENTIALLY OF UC PLUS U2C3 AND A CARBURIZABLE METAL CLADDING FOR SAID MATERIAL.
Claim 2
Dependent Claim
46 words
A URANIUM CARBIDE NUCLEAR REACTOR FUEL ELEMENT HAVING A CARBURIZABLE METAL CLADDING STABILIZED AGAINST CARBURIZATION BY CARBON TRANSFER FROM THE FUEL MATERIAL PRESENT, WHICH COMPRISES, IN COMBINATION, A CARBONSTABLE REACTOR FUEL MATERIAL CONSISTING ESSENTIALLY OF UC PLUS U2C3 AND A CARBURIZABLE METAL CLADDING FOR SAID MATERIAL.
Claim 3
Independent Claim
69 words
THE METHOD OF PREPARING A URANIUM CARBIDE NUCLEAR REACTOR FUEL ELEMENT HAVING A CARBURIZABLE METAL CLADDING STABILIZED AGAINST CARBURIZATION BY CARBON TRANSFER FROM THE FUEL MATERIAL PRESENT WHICH COMPRISES HEATING IN AN INERT ENVIRONMENT AT A TEMPERATURE OF AT LEAST 1000*C. HYPERSTOICHIOMETRIC URANIUM CARBIDE CONTAINING A UC2 PHASE TO TRANSFORM SAID UC2 TO U2C3 AND ASSEMBLING THE HEAT-TREATED URANIUM CARBIDE IN A METAL CLADDING TO FORM SAID FUEL ELEMENT.
