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...
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,...
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 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...
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...
The objective of this work was to determine and optimize the resolution of a neutron sensitive Multi-Channel Plate (MCP) detector in order to determine its capabilities in radiography and tomography. The Oregon State University, Neutron Radiography Facility added an MCP Detector in 2012 in order to analyze these capabilities. The...
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...
A phase distribution parameter has been added to the one-dimensional two-phase horizontal flow conservation equations. The phase distribution parameter was incorporated into the conservation equations in an attempt to add stability and remove correlation switching by incorporating gravity. Determination of the phase distribution parameter requires an average void fraction profile...
