Advancement Of Computational Nuclear Fuel And Safeguard Tools, Nathan Shoman May 2016

Advancement Of Computational Nuclear Fuel And Safeguard Tools, Nathan Shoman

Masters Theses

This thesis work was conducted in two separate but related areas: reactor physics and nuclear fuel safeguards. Reactor physics calculations at the assembly level are important to understand the buildup of fission products and major actinides. These calculations can be used to determine the content of a spent fuel assembly prior to reprocessing or disposal at a much cheaper price. This thesis presents an extension to the SCALE (A Nuclear Systems Modeling & Simulations Suite) by developing a lattice model and cross-section library for the CANada Deuterium Uranium (CANDU) 37 and 28 element assemblies. The previous cross-section library was based …


User Perspective And Analysis Of The Continuous-Energy Sensitivity Methods In Scale 6.2 Using Tsunami-3d, Elizabeth Lauryn Jones May 2015

User Perspective And Analysis Of The Continuous-Energy Sensitivity Methods In Scale 6.2 Using Tsunami-3d, Elizabeth Lauryn Jones

Masters Theses

The Tools for Sensitivity and UNcertainty Analysis Methodology Implementation (TSUNAMI) suite within the SCALE code system makes use of eigenvalue sensitivity coefficients to enable several capabilities, such as quantifying the data-induced uncertainty in calculated eigenvalues and assessing the similarity between different critical systems. The TSUNAMI-3D code is one tool within the TSUNAMI suite used to calculate eigenvalue sensitivity coefficients in three-dimensional models. The SCALE 6.1 code system includes only the multigroup (MG) mode for three-dimensional sensitivity analyses; however, the upcoming release of SCALE 6.2 will feature the first implementation of continuous-energy (CE) sensitivity methods in SCALE. For MG calculations, TSUNAMI-3D …
