LaFleur, Adrienne; Charlton, William (2007-09-17)An algorithm was developed that uses measured isotopic ratios from fission product residue following the detonation of a high-enriched uranium nuclear weapon to compute the original attributes of the material used in the ...
-
Parham, Neil A. (2010-07-14)For the Texas A&M University Nuclear Science Center reactor a fuel depletion code was created to develop real-time fuel management capability. This code package links MCNP8 and ORIGEN26 and is interfaced through a Visual ...
-
Candalino, Robert Wilcox (Texas A&M University, 2006-10-30)A neutronic and thermal hydraulic analysis of the 1-MW TRIGA research reactor at the Texas A&M University Nuclear Science Center using a new low enriched uranium fuel (named 30/20 fuel) was completed. This analysis provides ...
-
Ghanbari, Roushan (2012-10-19)As the nuclear industry grows around the globe, it brings with it a need for more safeguards and proliferation resistant technologies. The International Atomic Energy Agency (IAEA) depends on effective containment and ...
-
Hellfeld, Daniel (2015-05-06)Cubic meter sized liquid scintillator detectors have demonstrated that the operational status, power level, and changes in fuel composition of a critical nuclear reactor system can be remotely measured with the antineutrino ...
-
Hausaman, Jeffrey Stephen (2012-02-14)The development of fast reactor systems capable of burning recycled transuranic (TRU) isotopes has been underway for decades at various levels of activity. These systems could significantly alleviate nuclear waste storage ...
-
Miller, Karen Ann (2011-08-08)Radiation portal monitors are being deployed at border crossings throughout the world to prevent the smuggling of nuclear and radiological materials; however, a tension exists between security and the free-flow of commerce. ...
-
Keith, Corey C (2016-01-22)Nuclear signatures, whether for forensics or safeguards applications, utilize two broad classes: comparative and predictive. While comparative methods analyze a sample against a database of previously measured samples, ...
-
Fox, Grant R. (2010-07-14)This research conducts tribological investigation in three areas. The first area of research is to obtain basic understanding of tribological properties of high performance Inconel alloys. Pin-on-disk testing was conducted ...
-
Johansen, Mary Amelia (2016-04-08)The historic Joint Comprehensive Plan of Action (JCPOA) was implemented on January 16, 2016 between the Islamic Republic of Iran and the E3/EU+3. The JCPOA hopes to ensure that the nuclear program in Iran will exist solely ...
-
Conchewski, Curtis (2012-10-19)This thesis examines how perturbing selected adversary capabilities in a design basis threat (DBT) may affect the assessment of a facility's security system performance. We found that using a strictly defined DBT to design ...
-
Radioactive Flow Characterization for Real-Time Detection Systems in UREX+ Nuclear Fuel Reprocessing Hogelin, Thomas Russell (2011-02-22)The reprocessing of used nuclear fuel requires the dissolution and separation of numerous radioisotopes that are present as fission products in the fuel. The leading technology option in the U.S. for reprocessing is a ...
-
Metcalf, Richard (2012-02-14)Nuclear safeguards are intrinsic and extrinsic features of a facility which reduce probability of the successful acquisition of special nuclear material (SNM) by hostile actors. Future bulk handling facilities in the United ...
-
Scipolo, Vittorio (Texas A&M University, 2005-11-01)Tomography refers to the cross-sectional imaging of an object from either transmission or reflection data collected by illuminating the object from many different directions. Classical tomography fails to reconstruct the ...
-
Parkison, Adam J (2013-06-04)The fundamental behavior underpinning a new processing concept was demonstrated which is capable of separating uranium from zirconium in U-Zr alloys through the formation and selective volatilization of their respective ...
-
Simulation of Nuclear Resonance Fluorescence for the Quantification of Plutonium-239 in Nuclear Fuel Gerhart, Jeremy Jens (2015-12-08)There is a need for a technique that is able to quickly and accurately quantify the amount of ^239Pu in spent nuclear fuel. With the recent developments of mono-energetic gamma-ray systems, it may be possible to use Nuclear ...
-
Creasy, John Thomas (2012-02-14)Uranium-Molybdenum (U-Mo) alloys are of interest to the nuclear engineering community for their potential use as reactor fuel. The addition of molybdenum serves to stabilize the gamma phase of uranium, as well as increasing ...
-
Horowitz, Steven Michael (2015-07-27)This thesis investigates the ability of a high-purity germanium detector to perform post-detonation forensics on the debris from several types of nuclear weapons 24 hours after detonation. The ultimate result of this ...
-
Watson, Aaron Michael (Texas A&M University, 2006-04-12)The source and nature, as well as the history of ray-effects, is described. A benchmark code, using piecewise constant functions in angle and diamond differencing in space, is derived in order to analyze four sample problems. ...
