(Texas A&M University, 2007-09-17)A beta-emitting glass seed was proposed for the brachytherapy treatment of prostate cancer. Criteria for seed design were derived and several beta-emitting nuclides were examined for suitability. 142Pr was selected as the ...
-
(2019-04-15)When it comes to reactor power monitoring, the old adage is the more information the better. An undetected hot spot or unexpected power shift could cause an early shutdown of the plant and have economic consequences. ...
-
(2022-10-19)Radiation detection software is a critical component of detection systems used to identify and ultimately prevent the spread of harmful radiation. Monitoring is critical for a variety of settings which include security, ...
-
(2022-04-19)The residual Monte Carlo (RMC) method is also known in the literature as sequential Monte Carlo and reduced-source Monte Carlo. Given a Monte Carlo method for solving a linear equation and an approximate solution to that ...
-
(2022-12-08)The simulation of radiation neutron transport involves a complex system of partial differential equations. Methods in solving these systems of equations can be categorized into two areas of concern, stochastic and ...
-
(2022-04-13)This work develops a non-intrusive, equation-free reduced-order model (ROM) for parametric reactor kinetics simulations. Non-intrusive, equation-free ROMs have many distinctive advantages compared to their intrusive ...
-
(2022-10-06)This work presents a parametric, non-intrusive, data-driven reduced-order model (ROM) for parametric multigroup radiation transport. Full-order models (FOMs) for radiation transport are often costly in terms of computational ...
-
(2012-11-28)In this dissertation, advanced numerical methods for highly forward peaked scattering deterministic calculations are devised, implemented, and assessed. Since electrons interact with the surrounding environment through ...
-
(Texas A&M University, 2006-10-30)Due to increasing terrorist threats and illegal proliferation of nuclear material and technology, there is a need for increased research in the area of detection of smuggled fissile material, some of which is designated ...
-
(2017-11-07)To address the evolving needs of dry storage, this research developed an optimization methodology to identify loading configurations to minimize the number of casks, their heat load, and the time when they meet transportation ...
-
(2012-02-14)In this dissertation, we discuss an adaptive angular discretization scheme for the neutral-particle transport equation in three dimensions. We mesh the direction domain by dividing the faces of a regular octahedron into ...
-
(2009-05-15)The approaches for discretizing the direction variable in particle transport calculations are the discrete-ordinates method and function-expansion methods. Both approaches are limited if the transport solution is not ...
-
(2016-07-27)We present a new family of discrete-ordinates (Sn) angular quadratures based on discontinuous finite elements (DFEM) in angle. The angular domain is divided into spherical quadrilaterals (SQs) on the unit sphere surface. ...
-
(2010-01-16)In this dissertation, we develop Adaptive Mesh Refinement (AMR) techniques for the steady-state multigroup SN neutron transport equation using a higher-order Discontinuous Galerkin Finite Element Method (DGFEM). We propose ...

-
(2016-04-27)Uncertainty quantification and sensitivity analysis (UQSA) is becoming an essential component for engineering and physics modeling. The growth of UQSA can be attributed to improved statistical methodologies and computational ...
-
(2018-05-04)Adjoint methods can provide a first-order approximation of the response a physical system experiences due to a perturbation in the system’s parameters. However, when applying the method to time dependent transport, memory ...
-
Adjoint-Based Uncertainty Quantification and Sensitivity Analysis for Reactor Depletion Calculations (2013-08-02)Depletion calculations for nuclear reactors model the dynamic coupling between the material composition and neutron flux and help predict reactor performance and safety characteristics. In order to be trusted as reliable ...
