  • 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,...

  • High speed motion neutron radiography of two-phase flow

    Creator:
    Wang, Shou-Kong Lancelot
    Abstract:
    Current research in the area of two-phase flow utilizes a wide variety of sensing devices, but some limitations exist on the information which can be obtained. Neutron radiography is a feasible alternative to "see" the two-phase flow. A system to perform neutron radiographic analysis of dynamic events which occur on...

  • A simulated two-group method for computing boiling water reactor power distributions

    Creator:
    Hatteberg, Ronald Leonard
    Abstract:
    A computer code capable of modeling the burnup dependent static behavior of a boiling water reactor was developed. The code calculates three-dimensional quarter core power distributions using a simulated two-group diffusion theory model. Thermal-hydraulic calculations account for the interaction between power, coolant flow, and void fraction distributions. Cross sections are...

  • A comparative study of nodal course-mesh methods for pressurized water reactors

    Creator:
    Bukar, Kyari Abba
    Abstract:
    Several computer codes based on one and two-group diffusion theory models were developed for SHUFFLE. The programs were developed to calculate power distributions in a two-dimensional quarter core geometry of a pressurized power reactor. The various coarse-mesh numerical computations for the power calculations yield the following: the Borresen's scheme applied...

  • PERT-IV, a two-dimensional perturbation theory code for fast reactors

    Creator:
    Hardie, Ralph Wayne
    Abstract:
    A two-dimensional perturbation theory computer code, PERT-IV, has been developed that will calculate reactivity coefficients, the delayed neutron fraction, and the neutron generation time. The program uses the output flux and adjoint flux from either a diffusion theory or transport theory program. A discussion and derivation of the perturbation equation...

  • Numerical solutions of the neutron transport equation

    Creator:
    Skeen, David Roy
    Abstract:
    Because of the high cost of fuel for nuclear reactors, fuel cycle costs must be predicted accurately. This leads to the high cost computer computations and a search for cheaper yet still accurate methods. For this paper we have chosen to study an alternate method for calculating thermal neutron cell...

  • A method for calculation of group-averaged resonance parameters

    Creator:
    Nail, James Harold
    Abstract:
    A method of treating resonance captures for few energy group calculations is developed using the Narrow Resonance-Infinite Absorber approximation to the resonance integral. The application of this method is not restricted to this approximation, however, as other approximations to the resonance integral could also be used. The approach presented defines...

  • Energy models for computing fast reactor parameters

    Creator:
    Lorenzini, Paul Gilbert
    Abstract:
    Because of the complicated form of the diffusion equation, approximations are necessary to treat the energy dependence for practical problems. The standard model is the few group approximation. A second approximate form, the overlapping group or modal method, is examined and more fully developed in this work to provide an...

  • Neutron shadow holography: a feasibility study

    Creator:
    Coe, Douglas H.
    Abstract:
    Neutron shadow holography is a method of obtaining a three-dimensional neutron radiograph of an object using a Fresnel zone plate as an encoding aperture. The object is reconstructed by passing laser light through a miniature copy of the radiograph. The technique has been applied extensively with X-rays and gamma rays...

    Abstract:
    A system to perform neutron radiographic analysis of dynamic events taking place over the order of several milliseconds has been developed at Oregon State University. The design consists of a TRIGA reactor capable of pulsing to 3000 MW peak power, a neutron beam collimator with an L/D of about 30:1,...
