Analysis of Neutron Environments in Advanced Reactors Vs. Triga Reactor for In-Core Behavior Studies (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 ...
-
(2021-04-19)Nuclear energy is an attractive source of energy because it decreases our dependence on fossil fuels. Emission of greenhouse gases by burning fossil fuels and the limited supply of oil, gas, and coal, makes nuclear energy ...
-
(2023-05-04)The proliferation resistance analysis of re-processing and re-enriching spent uranium fuel discharged from a Canadian Deuterium Uranium (CANDU) reactor with regards to the accumulation of 236U and 238Pu was conducted. ...
-
(2020-06-24)Several studies have reported the effect of holdup on detectors and the magnitude of holdup in nuclear material processing facility. However, scenarios how diversion of special nuclear material occurs in the presence of ...
-
(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 ...
-
(2010-07-14)Reprocessing nuclear fuel is becoming more viable in the United States due to the anticipated increase in construction of nuclear power plants, the growing stockpile of existing used nuclear fuel, and a public desire to ...
-
(2018-05-31)An active well coincidence counter (AWCC) is used for Nondestructive Assay (NDA) of special nuclear material. This counter was developed for the International Atomic Energy Agency (IAEA) to perform in field inspections. ...
-
(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 ...
-
(2011-08-08)A special work evolution was performed at Los Alamos National Laboratory (LANL) with a particular 73As/74As source but the worker’s extremity dosimeter did not appear to provide appropriate dosimetric information for the ...
-
(2020-01-15)In response to the economic realities of the American nuclear market, numerous corporations have formed with the goal of bringing new types of nuclear reactor designs to market. A survey was undertaken of these emerging ...

(2016-05-24)The study of thermal radiative transfer in the high energy density regime is important to the National Nuclear Security Administration, and experiments are an important component of such studies. Strong non-linear coupling ...
-
(Texas A&M University, 2004-09-30)Using the computer code Monte Carlo N-Particle (MCNP), doses were calculated for organs of interest such as the large intestine, urinary bladder, testes, and kidneys while patients were undergoing prostate brachytherapy. ...
-
(Texas A&M University, 2006-10-30)The rising desire for individualized medical physics models has sparked a transition from the use of tangible phantoms toward the employment of computational software for medical physics applications. One such computational ...
-
(2018-05-01)A radiation detector’s sensitivity is important when designing survey plans. A measure of sensitivity is minimum detectable activity (MDA) which is the lowest amount of activity required for a signal to be distinguished ...
-
(2009-05-15)The objective of this research was to develop a complex MCNPX model of the human head to predict absorbed dose distributions during proton therapy of ocular tumors. Absorbed dose distributions using the complex geometry ...
-
(2021-06-08)Reprocessing of used nuclear fuel being the acquisition path for Pu and U by the proliferating states, the roles of intrinsic and extrinsic barriers to proliferation through this path need a deeper analysis. Denaturing of ...
-
(2021-06-23)An analysis of a pebble bed reactor (PBR) system has been completed to assess its proliferation resistance (PR) against multiple special nuclear material-SNM (uranium and plutonium) diversion scenarios. The PR assessment ...
