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...

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...

Neutron-induced autoradiography of lithiasilica microspecimens : Specimen preparation and preliminary alpha tracking

Creator:: Wood, F. W. (Floyd William), 1926-
Abstract:: Lithia-silica compositions between lithium disilicate and pure silica were explored theoretically and experimentally, with special emphasis on structural miscibility. Diffusion couples of vitreous materials were prepared and annealed. Best success in preparation was achieved by using electron-bombardment heating in vacuum to melt the less refractory glass and let it solidify...

Electron microscopic observation of alpha particle tracks in cellulose nitrate

Creator:: Fish, Robert Lawrence
Abstract:: The work in this thesis involves the development of specimen preparation techniques for the observation with an electron microscope of alpha particle tracks in cellulose nitrate plastic. Both direct observation using thin films and replica production techniques were investigated. Direct observation of the alpha tracks was accomplished by cutting thin...

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...

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...

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...

One and two dimensional space-energy flux synthesis with spatially discontinuous trial functions

Creator:: Olson, Willard Orvin
Abstract:: The development of nuclear reactors as an energy source requires a substantial investment in capital and effort. This development depends heavily on accurate calculational methods. Space-energy flux synthesis, also variously called the spectral synthesis method, modal method, and overlapping group method, is one possible method. In this method the energy...

Optimization of in-core nuclear fuel management in a pressurized water reactor

Creator:: Stout, Richard Bartholomew
Abstract:: Fuel loading patterns which have a minimum power peak are economically desirable to allow power reactors to operate at the highest possible power density and to minimize the possibility of fuel failure. A computer code called SHUFLE was developed for pressurized water reactors which shuffles the fuel in search of...

High speed motion neutron radiography

Creator:: Bossi, Richard Henry
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,...
