  • Moderating fuel rods including metal hydride and methods of moderating fuel bundles of boiling water reactors using the same
    Patent number: 9922732
    Abstract: A moderating fuel rod for a boiling water reactor may include a nuclear fuel section; a neutron moderator section including a metal hydride; and a threaded connector joining the nuclear fuel section and the neutron moderator section. By including one or more moderating fuel rods in a fuel bundle, the neutron moderation within the fuel bundle may be improved, thereby allowing energy to be more efficiently extracted from the entire length of the fuel bundle.
    Type: Grant
    Filed: October 7, 2014
    Date of Patent: March 20, 2018
    Assignee: Global Nuclear Fuel-Americas, LLC
    Inventors: John Christopher Hannah, Gerald Dean Kvaall, Jr.

  • FAST FLUX SHIELD AND METHOD OF REDUCING FAST NEUTRON FLUENCE AT A CORE SHROUD OF A BOILING WATER REACTOR USING THE SAME
    Publication number: 20160099083
    Abstract: A boiling water reactor core according to an example embodiment may include a core shroud and a plurality of fuel bundles within the core shroud. A plurality of shielding bundles are arranged as a fast flux shield between the plurality of fuel bundles and the core shroud. The plurality of shielding bundles include a metal hydride as a neutron moderator.
