(2014-09-18)With Pu-238 in short supply, it is necessary to investigate other potential fuel sources that may be suitable for powering radioisotope thermoelectric generators (RTGs). This report has investigated several candidate ...
-
(2014-04-27)The objective of this thesis work is to utilize computational models to reliably predict the intrinsic signature of the weapons-grade plutonium separated from a Pressurized Heavy Water Reactor (PHWR), specifically an Indian ...
-
(2021-08-19)A symbiosis of Renewable Energy Sources with an Alternative Energy Source is necessary to satisfy the ever-changing energy demands. Solar and wind energy are taken into consideration, yet the intermittency of both present ...

Design and PIV Measurements on a Wire-Wrapped 61-Rod Hexagonal Fuel Assembly Experimental Facility (2017-05-04)The superior uranium utilization efficiency of fast spectrum reactors relative to thermal spectrum reactors was recognized shortly after commercial reactor development started. The sodium fast reactor design, a type of ...
-
(2009-05-15)Neutron coincidence counting is an important passive Nondestructive Assay (NDA) technique widely used for qualitative and quantitative analysis of nuclear material in bulk samples. During the fission process, multiple ...
-
(2012-10-19)An electrolytic cell was designed, built, and tested with several proof-of-concept experiments in which Zircaloy material was charged with hydrogen in order to generate zirconium hydride formations. The Electrolytic Charging ...
-
(2016-08-09)Experimental investigations of separating actinides (uranium and plutonium) from fission products (FP) were conducted using a modified Plutonium Uranium Recovery by Extraction (PUREX) process. The sample under investigation ...
-
(2010-07-14)In recent years, there have been several research endeavors to increase the ability to identify and quantify special nuclear material in field measurements. These have included both gamma spectroscopy and neutron coincidence ...
-
(2015-11-24)To evaluate the behavior of inert helium gas bubbles in zirconium three variants of the metal were implanted with 140 keV helium ions to a total fluence of 3×10^17 cm^−2 and characterized in cross-section TEM in their ...
-
(2011-10-21)A new high-fidelity integrated system method and analysis approach was developed and implemented for consistent and comprehensive evaluations of advanced fuel cycles leading to minimized Transuranic (TRU) inventories. The ...
-
(2021-01-22)Cube satellites (CubeSats) present a unique platform for monitoring localized processes anywhere within the Earth’s surface or atmosphere using novel data analysis techniques. Areas of interest can be targeted at certain ...
-
(2017-07-25)The present study focuses on the validation of the multi-scale CFD simulations for the nuclear systems. It is mainly divided into the three applications; First is the validation analysis of the large scale PANDA experiment ...
-
(2018-10-29)The Reactor Core Isolation Cooling (RCIC) System is a safety system that provides water to the reactor pressure vessel during off-normal Boiling Water Reactor (BWR) conditions, such as reactor isolation from the turbines ...
-
(Texas A&M University, 2005-08-29)An RDD attack against the U.S. is something America needs to prepare against. If such an event occurs the ability to quickly identify the source of the radiological material used in an RDD would aid investigators in ...
-
(2017-12-08)The sodium fast reactor is a type of liquid metal fast breeder nuclear reactor. Fast reactors offer a number of benefits over conventional thermal reactors such as, a more abundant source of fuel, and are inherent increases ...
-
(2021-05-03)A remote laboratory for radiation detection and physical security was developed and implemented to provide students and professionals with education and training in nuclear security. Beginning with a proof-of-concept remote ...
-
(2020-12-02)The helical coil steam generator (HCSG) is a specific type of shell-and-tube heat exchanger known for having a higher heat transfer coefficient than similar straight tube designs. Because of its compactness and higher heat ...
-
(2013-02-04)In some pathogens such as Ehrlichia chaffeensis, Anaplasma phagocytophilum, Chlamydia, and Shigella, secreted effector proteins have been found to localize to the nucleus and alter the host’s immune response by modulating ...
-
(Texas A&M University, 2006-04-12)The current "diffusion-retention" model for protein trafficking to the inner nuclear membrane (INM) proposes that INM proteins diffuse laterally from the membrane of the endoplasmic reticulum into the INM and are then ...
-
(2012-11-15)One of the greatest challenges facing the nuclear power industry is the final disposition of nuclear waste. To meet the needs of the nuclear power industry, a new fuel assembly design, called DUPLEX, has been developed ...
