  • Swelling-resistant nuclear fuel
    Patent number: 8085894
    Abstract: A nuclear fuel according to one embodiment includes an assembly of nuclear fuel particles; and continuous open channels defined between at least some of the nuclear fuel particles, wherein the channels are characterized as allowing fission gasses produced in an interior of the assembly to escape from the interior of the assembly to an exterior thereof without causing significant swelling of the assembly. Additional embodiments, including methods, are also presented.
    Type: Grant
    Filed: April 11, 2008
    Date of Patent: December 27, 2011
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: Athanasios Arsenlis, Joe Satcher, Jr., Sergei O. Kucheyev
  • TRISO FUEL FOR HIGH BURN-UP NUCLEAR ENGINE
    Publication number: 20110091004
    Abstract: A fuel particle for use in a fusion-fission nuclear engine includes a fuel kernel and a buffer layer surrounding the fuel kernel. The fuel particle also includes a pyrolytic carbon layer surrounding the buffer layer and a silicon carbide layer surrounding the buffer layer. The silicon carbide is characterized by a stress less than 450 MPa at 95% burn-up. The fuel particle further includes a second pyrolytic carbon layer surrounding the silicon carbide layer.
