  • Feasibility Study of Using HANARO Fuel Rods in WWR-SM Reactor

    Creator:
    Peguero, Lara M.
    Abstract:
    Interest in increased fuel supply stability has driven an investigation into possible alternate fuel for use in the WWR-SM research reactor at the Institute of Nuclear Physics in Uzbekistan. The WWR-SM is a high-power, pool-type research reactor currently utilizing IRT-4M fuel made by a single Russian supplier. A candidate for...

  • Thermal conductivity modeling of unrestructured sphere pac nuclear fuels

    Creator:
    Willison, James Stuart
    Abstract:
    In order to properly model the temperature distribution of a nuclear fuel pin, the thermal conductivity of the fuel must be known. For sphere pac fuel, the modeling of the conductivity is complicated due to the fact that the fuel is a collection of spheres in a random packed bed....

  • Gadolinium particle depletion in light water reactor fuel rods

    Creator:
    Hartley, Kenneth D.
    Abstract:
    Gadolinium is an important element to the Nuclear Fuel Industry. Two of the seven naturally occurring isotopes of gadolinium have very large absorption cross sections for thermal neutrons. The isotopes of ¹⁵⁵ Gd and ¹⁵⁷ Gd readily absorb thermal neutrons and transmute to ¹⁵⁶ Gd and ¹⁵⁸ Gd which are...

  • A two-group study on the gadolinium particle depletion in light water reactor fuel rods

    Creator:
    Lee, Chungchan
    Abstract:
    The effect of gadolinia particles on the assembly criticality of a light water reactor was investigated using two 2-group models. The particle effect was calculated by comparing the criticalities of two fuel assemblies, each containing one gadolinia-poisoned rod. For purposes of comparison, both rods contained an equal quantity of gadolinia,...
