Dynamic System Scaling Application to Accelerated Nuclear Fuel Testing

Creator:: Yoshiura, Ramon K.
Abstract:: The development of nuclear fuel and materials requires is a continuous effort to investigate the acute and prolonged effects of irradiation, thermal-material stress, chemical change, or other conceivable damage mechanics acquired during normal operation or accident scenarios throughout its lifetime. As in-core fuel property measurement techniques advance to support in...
Resource Type:: Dissertation

The Development of a Mechanistic Critical Heat Flux Correlation

Creator:: Luitjens, Jeffrey M.
Abstract:: A mechanistic based critical heat flux (CHF) correlation has been developed derived from a mass, momentum, and energy balance at a nucleation site for water. The trigger mechanism for the CHF condition is postulated to be related to the maximum boiling frequency on a heated surface. It is observed that...

A theoretical and experimental study of self-propagating high-temperature synthesis of titanium carbide

Creator:: Huque, Ziaul
Abstract:: Self-propagating high-temperature synthesis (SHS) is a new method of producing advanced ceramic materials and offers an attractive alternative to conventional methods of materials processing. An experimental investigation was carried out to determine the SHS reaction wave propagation speed in a vertical cylindrical compact made from a mixture of titanium and...

Nonintrusive intelligent monitoring for nuclear power plant emergency classification

Creator:: Greene, Kenneth R. (Kenneth Ray), 1958-
Abstract:: A prototype real-time process monitoring emergency classification expert system, RT/EM-CLASS, has been developed for use at the Trojan Nuclear Power Plant. This knowledge-based system features the integration of electronically sensed plant data with the menu selection data representation of its predecessor, EM-CLASS. This prototype demonstrates the techniques required to acquire...

Experimental simulations of a rotating bubble membrane radiator for space nuclear power systems

Creator:: Al-Baroudi, Homan Mohammed-Zahid
Abstract:: A rotating, flat plate condensation experiment has been developed to investigate the heat of the Rotating Bubble Membrane Radiator (RBMR). The RBMR is a proposed heat rejection system for space applications which uses working fluid condensation on the inside surface of a rotating sphere to reject heat to space. The...

Temperature measurement, electrical characteristics, and lorentz mixing of alkali seeded flames

Creator:: Pattee, Heidi Ann
Abstract:: When trace quantities of an alkali element are added to a flame, its optical and electrical properties change significantly. Addition of alkali seed to both premixed and diffusion flames has been used in the development of two new techniques, one for flame temperature measurement and the other for enhanced mixing....

Investigation of instantaneous hydrodynamics and heat transfer to a horizontal tube immersed in a high-temperature gas-solid fluidized bed of large particles

Creator:: Burr, Marlene Mainland
Resource Type:: Dissertation

An inherently parallel Monte Carlo linear systems solver applied to neutron diffusion equations

Creator:: Eccleston, Bradley R.
Abstract:: Linear solvers are often used to solve neutron diffusion problems. These tools have two significant shortcomings. First, parallel implementations provide only a modest speedup. The operations cannot be divided cleanly between processors. Second, for large matrices they can be very slow. Our primary goal is to find a new method...

Nodal methods for calculating nuclear reactor transients, control rod patterns, and fuel pin powers

Creator:: Cho, Byung-Oh
Abstract:: Nodal methods which are used to calculate reactor transients, control rod patterns, and fuel pin powers are investigated. The 3-D nodal code, STORM, has been modified to perform these calculations. Several numerical examples lead to the following conclusions: (1) By employing a thermal leakage-to-absorption ratio11 (TLAR) approximation for the spatial...
Resource Type:: Dissertation

A unified model of one-dimension two-fluid horizontal flows and its stability analysis

Creator:: Kim, Dong-Wan
Abstract:: An improved version of the one-dimensional horizontal two-fluid flow model has been developed by incorporating physical terms for gravity and local void fraction profiles. Introduction of an interface mixing layer concept allows the one-dimensional two-fluid model to remain hyperbolic. This will overcomes a major obstacle in using the current one-dimensional...
