Implementation and Verification of the Subgroup Decomposition Method in the TITAN 3-D Deterministic Radiation Transport Code
(Virginia Tech, 2014-05-07)
The subgroup decomposition method (SDM) has recently been developed as an improvement over the consistent generalized energy condensation theory for treatment of the energy variable in deterministic particle transport ...
Development of the Adaptive Collision Source Method for Discrete Ordinates Radiation Transport
(Virginia Tech, 2015-05-08)
A novel collision source method has been developed to solve the Linear Boltzmann Equation (LBE) more efficiently by adaptation of the angular quadrature order. The angular adaptation method is unique in that the flux from ...
Development of a Novel Fuel Burnup Methodology and Algorithm in RAPID and its Benchmarking and Automation
(Virginia Tech, 2018-08-02)
Fuel burnup calculations provide material concentrations and intrinsic neutron and gamma source strengths as a function of irradiation and cooling time. Detailed, full-core 3D burnup calculations are critical for nuclear ...
A Novel Methodology for Iterative Image Reconstruction in SPECT Using Deterministic Particle Transport
(Virginia Tech, 2015-04-30)
Single photon emission computed tomography (SPECT) is used in a variety of medical procedures, including myocardial perfusion, bone metabolism, and thyroid function studies. In SPECT, the emissions of a radionuclide within ...
Analysis and Improvement of the bRAPID Algorithm and its Implementation
(Virginia Tech, 2019-07-18)
This thesis presents a detailed analysis of the bRAPID (burnup for RAPID – Real Time Analysis for Particle transport and In-situ Detection) code system, and the implementation and validation of two new algorithms for ...
Benchmarking of the RAPID Eigenvalue Algorithm using the ICSBEP Handbook
(Virginia Tech, 2019-09-17)
The purpose of this thesis is to examine the accuracy of the RAPID (Real-Time Analysis for Particle Transport and In-situ Detection) eigenvalue algorithm based on a few problems from the ICSBEP (International Criticality ...
