(2023-04-05)Due to the growing interest in advanced reactors such as molten salt reactors (MSRs), it is important to better understand some of their advantages. For example, a significant potential advantage of MSRs is their ability ...
-
(2011-08-04)With active research projects related to nuclear waste immobilization and high conductivity nuclear fuels, a thermal model has been developed to simulate the temperature profile within a heat generating cylinder in order ...
-
(2021-03-22)In 1942 the U.S. achieved criticality with Chicago Pile-1 and in 1952 constructed the first nuclear-powered submarine. Given the rapid advancements in the first decade of nuclear reactor demonstration, it would not be a ...
-
(2011-08-08)High Temperature Gas-cooled Reactors (HTGRs) can provide clean electricity,as well as process heat that can be used to produce hydrogen for transportation and other sectors. A prototypic HTGR, the Next Generation Nuclear ...
-
(2021-04-26)The original molten salt reactor (MSR) concepts were developed at Oak Ridge National Laboratory (ORNL) in the 1960s. Increasing energy demands and concerns about global CO2 emissions have emphasized the need for advanced ...
-
(2012-07-16)This work focuses on both high fidelity experimental and numerical thermal hydraulic studies and advanced frequency decomposition methods. The major contribution of this work is a proposed method for spatio-temporal ...
-
(Texas A&M University, 2007-09-17)Robust and reliable quantitative proliferation resistance assessment tools are critical to a strengthened nonproliferation regime and to the future deployment of nuclear fuel cycle technologies. Efforts to quantify ...
-
(2016-12-08)This thesis examines five chemical solutions that are considered to be representative of the solution created in the containment sump during a postulated LOCA (loss of coolant accident) at a Pressurized Water Reactor (PWR) ...
-
(2015-09-29)The Fuel Cycle and Materials Laboratory at Texas A&M University needs a method of removing impurities from depleted uranium samples. A non-aqueous, lab-scale electrorefiner will be constructed to solve this problem. The ...
-
(2018-08-03)A novel hierarchical heuristic engineering design method is developed that is based on levels of abstraction. This was created in response to the dearth of engineering design methods geared for nuclear engineering and the ...
-
(2009-05-15)The experiments performed for this thesis were designed to define the primary process variables of time, temperature, and atmosphere for an engineering system that will produce metal powder from recycled nuclear fuel ...
-
(2010-10-12)The present work examines the potential impact of changes in climatic conditions on the long-term functioning of nuclear power plants. Nuclear power plants are potentially susceptible to changes both in acute risks, such ...
-
(2017-05-10)During the initial stage of a Loss of Coolant Accident (LOCA), known as the blowdown phase, the high-temperature and pressure break flow can impinge on thermal insulation and generate a substantial amount of debris in ...
-
(2020-09-07)The first study in this work focuses on the 23Mg(p,g)24Al reaction. Although several resonances may contribute to the overall rate at novae temperatures, the resonance at ~475 keV is thought to be dominant. The strength ...
-
(2016-12-08)The optimization of a complex system involves the determination of optimum values for a set of design parameters. The optimization search happens in order to meet a specific set of objectives concerning the quantities of ...
-
(2012-10-19)The goal of this research is to apply modern methods of analysis to the design of a tungsten-cermet Nuclear Thermal Rocket (NTR) core. An NTR is one of the most viable propulsion options for enabling piloted deep-space ...
-
(Texas A&M University, 2007-09-17)When target and projectile nuclei have a difference in neutron to proton ratio (N/Z), the quasiprojectiles formed in a deep inelastic collision (DIC) should have a mean N/Z between the N/Z of the target and the N/Z of the ...
-
(2013-11-27)The goal of this research was to develop a methodology to collect inventory estimates for the analysis and characterization of used fuel in the United States. To accomplish this, the Spent Fuel Database (SFD) was created. ...
-
(2022-08-17)The research performed here is focused on heat-pipe modeling and simulation and performance predictions. Heat-pipes are analyzed with axisymmetric assumptions that limit the validity towards geometries that cannot be reduced ...
