Journal ArticleDOI
Atomistic modeling of high temperature uranium–zirconium alloy structure and thermodynamics
Alexander P. Moore,Benjamin Beeler,Benjamin Beeler,Chaitanya Deo,Michael I. Baskes,Michael I. Baskes,Michael I. Baskes,Maria A. Okuniewski,Maria A. Okuniewski +8 more
TL;DR: In this article, a semi-empirical Modified Embedded Atom Method (MEAM) potential is developed for application to the high temperature body-centered-cubic uranium-zirconium alloy (γ-U-Zr) phase and employed with molecular dynamics (MD) simulations to investigate high temperature thermo-physical properties of U−Zr alloys.
Journal ArticleDOI
The role of the interface stiffness tensor on grain boundary dynamics
Fadi Abdeljawad,Fadi Abdeljawad,Stephen M. Foiles,Alexander P. Moore,Adam R. Hinkle,Christopher M. Barr,Nathan M. Heckman,Khalid Hattar,Brad L. Boyce +8 more
TL;DR: In this article, the authors examined the interface stiffness tensor of Σ3 GBs in nickel and showed that the stiffness can be much larger in magnitude and more anisotropic than the GB energy itself.
Journal ArticleDOI
Atomistic mechanisms of morphological evolution and segregation in U-Zr alloys
Alexander P. Moore,Chaitanya Deo,Michael I. Baskes,Michael I. Baskes,Michael I. Baskes,Maria A. Okuniewski,Maria A. Okuniewski +6 more
TL;DR: In this paper, a semi-empirical Modified Embedded Atom Method (MEAM) is used in conjunction with molecular dynamics (MD) and Monte Carlo (MC) simulations to investigate the properties and equilibrium configurations of the high temperature body-centered-cubic (bcc) uranium-zirconium (U-Zr) alloys.
Journal ArticleDOI
Resolution of Fission and Fusion Technology Integration Issues: An Upgraded Design Concept for the Subcritical Advanced Burner Reactor
Weston M. Stacey,C. L. Stewart,J.-P. Floyd,Theresa Wilks,Alexander P. Moore,A. T. Bopp,Maxwell Hill,S. Tandon,and A. S. Erickson +8 more
TL;DR: The subcritical advanced burner (SABR) as mentioned in this paper was designed for a 3000MW (thermal) annular, modular sodium pool-type fast reactor, fueled by metallic transuranic (TRU) fuel process.
Journal ArticleDOI
Understanding the uncertainty of interatomic potentials’ parameters and formalism
Alexander P. Moore,Alexander P. Moore,Chaitanya Deo,Michael I. Baskes,Michael I. Baskes,Michael I. Baskes,Maria A. Okuniewski,Maria A. Okuniewski,David L. McDowell +8 more
TL;DR: A sensitivity analysis of the modified embedded atom method (MEAM) potential for body-centered-cubic uranium and zirconium was performed in order to examine and understand the uncertainty in the parameters and formalism of the interatomic potential.
