Construction and calibration of a fast neutron spectrum generator

Creator:

Dobbin, Kenneth Dwight

Abstract:

A standard fast reactor spectrum can be created by the partial moderation of the U-235 fission spectrum in an air cavity. Spherical natural uranium shells are driven by thermal neutrons from a thermal column. The uranium is placed at the center of a spherical graphite hohlraum to reduce the anisotropic...

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,...

THE THESIS OF RICHARD HENRY BOSSI for the degree of DOCTOR OF PHILOSOPHY in Nuclear Engineering
A comparison of iterative methods for the solution of elliptic partial differential equations, particularly the neutron diffusion equation

Creator:

Schwinkendorf, Kevin N.

Abstract:

Two new concepts have been explored in solving the neutron diffusion equation in one and two dimensions. At the present time, the diffusion equation is solved using source iterations. These iterations are performed in a mathematical form which has a great deal of physical significance. Specifically, the neutron production term...
