An evaluation of finite difference methods for calculating heat transfer in fuel pins with eccentrically placed pellets

Creator:: McNair, Gary W.
Abstract:: In fuel pin fabrication, there is no assurance that a fuel pellet will be loaded concentrically. Therefore, azimuthal variations exist in the temperature field giving rise to asymmetry in the neutron flux distribution and pin stresses. Calculations must be made to determine the two dimensional temperature profile which may then...

Predicting Thermal Conductivity in Nuclear Fuels using Rattlesnake-Based Deterministic Phonon Transport Simulations

Creator:: Harter, Jackson R.
Abstract:: The Boltzmann transport equation derived in the Self-Adjoint Angular Flux (SAAF) formulation is applied to simulate phonon transport. The neutron transport code Rattlesnake is leveraged in this fashion, slightly modi ed to accept input from variables consistent with phonon transport simulations. Several benchmark problems are modeled to assess the potential...

A thermal hydraulics analysis of a molybdenum production element for implementation in TRIGA reactors

Creator:: Byfield, Patrick
Abstract:: The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...
