Cuvelier, Marie-Hermine (2012-07-16)Minimization of HLW inventories and U consumption are key elements guaranteeing nuclear energy expansion. The integration of complex nuclear systems into a viable cycle yet constitutes a challenging multi-parametric ...
-
Rodi, Paul J. (2012-07-16)This thesis involves exploring enhancement of estimating the probability of a critical station blackout in nuclear power plant operations by the use of direct numerical evaluation of multidimensional nonrecovery integrals. ...
-
Guy, Troy Lamar (2011-02-22)The present study is focused on evaluating higher actinides beyond uranium that are capable of supporting power and propulsion requirements in robotic deep space and interstellar exploration. The central technology in this ...

Analysis of Neutron Environments in Advanced Reactors Vs. Triga Reactor for In-Core Behavior Studies Marcantel, Grace Ann (2018-04-13)The Fluoride High-Temperature Reactor (FHR) and the Very High-Temperature Reactor (VHTR) are advanced reactor designs in the generation IV class. Advanced reactors operate in more strenuous conditions than older generation ...
-
Valverde, John M (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 ...
-
Frisani, Angelo (2011-08-08)The design of passive heat removal systems is one of the main concerns for the modular Very High Temperature Gas-Cooled Reactors (VHTR) vessel cavity. The Reactor Cavity Cooling System (RCCS) is an important heat removal ...
-
Lewis, Tom Goslee (2009-05-15)The current waste management strategy for spent nuclear fuel (SNF) mandated by the U.S. Congress is the disposal of high-level waste (HLW) in a geological repository at Yucca Mountain. Ongoing efforts on closed-fuel cycle ...
-
Atomic Scale Studies of the Stress Effects on Defect Kinetics and Damage Evolution of Irradiated Fe Kang, Changwoo (2018-01-11)Irradiation of the materials with neutrons or energetic particles creates a significant number of point defects and nucleates extended defects, such as dislocations and voids. These defects result in the changes of material ...
-
Freeman, Corey Ross (2009-05-15)Nuclear weapons proliferation produces a vehement global safety and security concern. Perhaps most threatening is the scenario of a rogue nation or a terrorist organization acquiring nuclear weapons where the conventional ...
-
Ahn, Sangjoon (2013-07-31)Uranium-zirconium (U-Zr) alloys comprise a class of metallic nuclear fuel that is regularly considered for application in fast nuclear energy systems. The U-10wt%Zr alloy has been demonstrated to very high burnup without ...
-
Ames, David E, II (Texas A&M University, 2006-10-30)Minor actinides represent the long-term radiotoxicity of nuclear wastes. As one of their potential incineration options, partitioning and transmutation in fission reactors are seriously considered worldwide. If implemented, ...
-
Gitau, Ernest Travis Ngure (2012-10-19)Pebble-fueled high temperature gas-cooled reactor (HTGR) technology was first developed by the Federal Republic of Germany in the 1950s. More recently, the design has been embraced by the People's Republic of China and the ...
-
Rauch, Eric B. (2010-07-14)Small graphite-moderated and gas-cooled reactors have been around since the beginning of the atomic age. Though their existence in the past has been associated with nuclear weapons programs, they are capable of being used ...
-
Lafleur, Adrienne (2011-10-21)The development of non-destructive assay (NDA) capabilities to directly measure the fissile content in spent fuel is needed to improve the timely detection of the diversion of significant quantities of fissile material. ...
-
Giannangeli, Donald D. J., III (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 ...
-
Zingan, Valentin Nikolaevich (2012-07-16)This work develops a discontinuous Galerkin finite element discretization of non- linear hyperbolic conservation equations with efficient and robust high order stabilization built on an entropy-based artificial viscosity ...
-
Environmental Aspects of Advanced Nuclear Fuel Cycles: Parametric Modeling and Preliminary Analysis Yancey, Kristina D. (2010-07-14)Nuclear power has the potential to help reduce rising carbon emissions, but to be considered sustainable, it must also demonstrate the availability of an indefinite fuel supply as well as not produce any significant negative ...
-
Worn, Cheyn (2012-07-16)Shadow shielding is a novel and practical concept for waste heat rejection from lunar surface spacecraft systems. A shadow shield is a light shield that shades the radiator from parasitic thermal radiation emanating from ...
-
Alajo, Ayodeji Babatunde (2011-08-08)The closure of the nuclear fuel cycle is a topic of interest in the sustainability context of nuclear energy. The implication of such closure includes considerations of nuclear waste management. This originates from the ...
