Patents by Inventor Roy G. Cooper

Roy G. Cooper has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Manufacture of nuclear fuel compacts
    Patent number: 4217174
    Abstract: Nuclear fuel rods are manufactured utilizing a graphite flour-pitch matrix formulation containing an additive. The matrix formulation has a decreased viscosity at fabrication temperatures which permits manufacture of the fuel rods with lower fabrication pressures. Also, the matrix formulation does not cause the fuel rod to adhere or bond to the fuel element during heat treatment of the fuel rod in the fuel element. The nuclear fuel rods are suitable for use in high temperature gas cooled nuclear reactors.
    Type: Grant
    Filed: December 8, 1977
    Date of Patent: August 12, 1980
    Assignee: General Atomic Company
    Inventors: David F. Leary, Roy G. Cooper, Gary N. Miertschin

  • Method for making nuclear fuel rods
    Patent number: 4024209
    Abstract: A mold cavity is only partially filled with nuclear fuel particles and is closed. The volume of the cavity is then reduced until the fuel particles substantially fill the mold cavity. The mold may be heated and a fluid solidifiable binder injected into the mold cavity to fill the interstices between the fuel particles while the cavity volume is further decreased during injection of the binder to avoid formation of voids. Flow of excess binder through an upper vent passage assures complete filling of the cavity.
