Fullerton, Christopher Todd (2017-07-18)In the event that a nuclear core cooling pipe ruptures, a loss of coolant accident (LOCA) scenario begins. Precipitates from dissolved ions can form and cause the emergency backup pumps to fail. Two aluminum products, an ...
-
Spear, Aubrey Alvin (2015-08-05)Government regulations on emission standards and constantly fluctuating fuel availability and prices have led to the need of more readily usable and available models for power generating combustors. A common, versatile, ...
-
Li, Han (2018-08-23)Turbulent jet interactions play a significant role in terms of momentum and heat transfer. Interactions of multiple turbulent jets occurs in next-generation nuclear reac- tors, where high-temperature flow mixing in the ...

Design and Preliminary Measurements Inside a Simplified High Temperature Gas-Cooled Reactor Building Silberberg, Mark Bryan (2017-04-28)A simplified high temperature gas-cooled reactor building was developed at Texas A&M University to understand the response of an actual facility to a depressurization accident scenario. A set of scaling laws were established ...
-
Seo, Youngjin (2009-05-15)A wetted wall cyclone is a device that delivers hydrosol in a single stage from which real-time detection of airborne particles can be readily achieved. This dissertation presents the design, development, and characterization ...
-
Kappes, Ethan Daniel (2018-12-13)Randomly packed pebble bed structures are found in many engineering applications, such as solar thermal batteries, chemical catalytic reactors, fluid refinement and filtering, magnetic refrigerators, biological tissues, ...
-
Arora, Ojasvin Sanjay (2023-08-02)Elevated temperatures and corrosive environments, typical of molten salt reactor’s operating conditions, may pose challenges to the functionality of instrumentation, sensors and key com-ponents of the cycle. Experimental ...
-
Frisani, Angelo 1980- (2012-12-07)Two immersed boundary methods (IBM) for the simulation of conjugate heat transfer problems with complex geometries are introduced: a finite element (IFEM) and a finite volume (IFVM) immersed boundary methods are discussed. ...
-
Kyriakopoulos, Vasileios (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) ...
-
Williams, Todd Andrew (2016-09-21)Public safety has long been one of the chief design concerns for Nuclear Power Plants (NPPs). For this reason, the design of a NPP must include plans for different accident scenarios called Design Basis Accidents (DBAs). ...
-
Mulloy Jr, John Patrick (2022-06-14)A hybridized Eulerian-Lagrangian solver was built in the open-source computational fluid dynamics code OpenFOAM. This solver was developed as a starting point for higher fidelity combined abrasion-ablation effects modeling ...
-
Galegar, Natalie C (2015-05-12)Grid-To-Rod-Fretting (GTRF) in PWR fuel assemblies is a major issue of concern to vendors and utilities. Instantaneous pressure fluctuations on a fuel rod surface can help characterize the GTRF potential within a fuel ...
-
Freitas Matozinhos, Camila (2022-07-27)Pressurized Water Reactors (PWRs) are the most common types of electricity generating reactors. Inside of a PWR core, pressurized liquid water is used as a coolant to remove the fission heat generated in the cylindrical ...
-
Oh, Sung Hyuk (2009-05-15)Experiments and numerical predictions were conducted to study heat (mass) transfer characteristics in a two-pass trapezoidal channel simulating the cooling passage of a gas turbine blade. Three different rib configurations ...
-
Orea, Daniel (2019-04-09)The main objective of "Experimental Flow Mixing Effects in the Cold-Leg of a Pressurized Water Reactor for CFD-UQ” is to investigate mixing phenomena in the cold leg and of a Pressurized Water Reactor. The experimental ...
