Ab initio molecular dynamics of paramagnetic uranium mononitride (UN) using disordered local moments
Mohamed AbdulHameed, Benjamin Beeler
This work presents an investigation of the thermophysical properties of paramagnetic uranium mononitride (UN) using ab initio molecular dynamics (AIMD) simulations combined with th…
The contribution of nitrogen Frenkel-pair formation to the high-temperature heat capacity of uranium mononitride
Mohamed AbdulHameed, Benjamin Beeler
The high-temperature heat capacity of uranium mononitride (UN) remains uncertain due to conflicting measurements and models above ~1700 K. To assess whether intrinsic defect format…
Modeling of silver transport in cubic SiC: Integrating molecular dynamics, bounds averaging, and uncertainty quantification
Mohamed AbdulHameed, Khadija Mahbuba, Mahmoud Yaseen +3
Silver released from TRISO fuel particles can migrate through the SiC layer and deposit on reactor components, posing radiation hazards and operational challenges. Despite numerous…
Molecular-dynamics study of diffusional creep in uranium mononitride
Mohamed AbdulHameed, Benjamin Beeler, Conor O. T. Galvin +3
Uranium mononitride (UN) is a promising advanced nuclear fuel due to its high thermal conductivity and high fissile density. Yet, many aspects of its mechanical behavior and micros…
Xe gas bubble re-solution in U-10Mo nuclear fuel
ATM Jahid Hasan, Linu Malakkal, Mathew Swisher +1
The U.S. High-Performance Research Reactor program aims to convert high-power research reactors from highly enriched uranium to low-enriched uranium using a monolithic U-10Mo fuel…
Effects of applied strain on radiation damage generation in body-centered cubic iron
Benjamin Beeler, Mark Asta, Peter Hosemann +1
Radiation damage in body-centered cubic (BCC) Fe has been extensively studied by computer simulations to quantify effects of temperature, impinging particle energy, and the presenc…
