  • Method for passivating uranium oxides to control oxidation, and the oxidation resisting uranium product thereof
    Patent number: 5066429
    Abstract: A process for controlling the oxidation reaction of oxides of uranium and fixing the ratio of oxygen to uranium in uranium oxide compounds by means of a passification process, and the stabilized uranium oxide compounds produced therefrom. The method is especially useful in the production of uranium oxide fuel for nuclear reactors.
    Type: Grant
    Filed: October 12, 1990
    Date of Patent: November 19, 1991
    Assignee: General Electric Company
    Inventors: Richard I. Larson, Richard P. Ringle, John L. Harmon
  • Binder system for the manufacture of nuclear pellets, and the method and product thereof
    Patent number: 4816187
    Abstract: A fugitive binder composition for compression molding uranium dioxide nuclear fuel comprising the reaction product of a strongly alkali water solution of a diamine and oxalate ions with uranium oxide which is free of carbonates and carbamates, and having the formula:[.sup.+ NH.sub.3 (CH.sub.2).sub.2 NH.sub.3.sup.+ ][UO.sub.2 (C.sub.2 O.sub.4).sub.2 (H.sub.2 O).sub.2 ][.sup.+ NH.sub.3 (CH.sub.2).sub.2 NH.sub.3.sup.+ ].
    Type: Grant
    Filed: March 5, 1987
    Date of Patent: March 28, 1989
    Assignee: General Electric Company
    Inventors: Richard I. Larson, Richard P. Ringle
  • Method and binder for the manufacture of nuclear fuel pellets, and the product
    Patent number: 4696769
    Abstract: A method and binder composition for prolonging the induced plasticity of a particulate ceramic material admixture comprising uranium dioxide and a fugitive binder, and product thereof, for subsequent compaction by compression molding in the manufacture of nuclear fuel pellets. The fugitive binder comprises a reaction product of an amine carbonate or amine carbamate and ammonium oxalate reacted with uranium dioxide at a temperature of at least 65.degree. C. The uranyl oxalate-carbonate reaction product has the composition of (UO.sub.2 (CO.sub.3) (C.sub.2 O.sub.4). 2H.sub.2 O). 2H.sub.2 O.
