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...

Feasibility of neutron radiographing reactor fuel assemblies

Creator:: Oien, C. T. (Charles T.)
Abstract:: Verification of fast reactor safety requires experiments wherein fuel bundles, enclosed in massive steel capsules, are subjected to simulated accident conditions in reactors such as TREAT(16) at ANL Idaho. To date, only small bundles (one to seven pins) have been tested in the experimental series. Determination of the fuel configuration...

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,...

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...

Application of high speed motion neutron radiography techniques to liquid streams injected into a pressurized steel chamber

Creator:: Tollefson, Dennis A.
Abstract:: A high speed motion neutron radiography system has been developed at Oregon State University which is capable of taking high speed neutron radiographs of events which occur on the order of one to two milliseconds or more. This system was used previously to demonstrate the application of high speed motion...

Optimum temporal and contrast considerations in extremely high speed motion neutron radiography

Creator:: Greek, Kevin J.
Abstract:: A facility developed using the OSU TRIGA pulsing capability and high speed motion photography has been used successfully for more than a decade to produce dynamic neutron radiographs of solid propellant combustion, two phase flow, and liquid streamflow. The existing imaging components have undergone little modification since the experiment's inception...

Real-time neutron radiography

Creator:: Newell, Daniel L.
Abstract:: A real-time neutron radiography system has been developed at Oregon State University which is capable of producing neutron radiographs of objects and events concurrent with the incident radiation. The purpose of this thesis is to demonstrate the feasibility of the real-time technique as a further application of neutron radiography at...

An integral transport theory boundary condition applied to close-packed lattice cells with investigations into a heuristic flux convergence method

Creator:: Sterbentz, James W.
Abstract:: Spatial flux profiles were calculated in idealized, optically-thin ( 1 mfp) cell systems using integral transport theory. Numerical accuracy improvement and convergence efficiency in computing these spatial flux profiles was the primary concern. Toward these ends, kernel volume-averaging techniques for curvilinear cell systems, a reflective angular-dependent edge source boundary condition...

An advanced nodal discretization for the quasi-diffusion low-order equations

Creator:: Nes, Razvan
Abstract:: The subject of this thesis is the development of a nodal discretization of the low-order quasi-diffusion (QDLO) equations for global reactor core calculations. The advantage of quasi-diffusion (QD) is that it is able to capture transport effects at the surface between unlike fuel assemblies better than the diffusion approximation. We...
