A model of grain growth in UN integrating molecular dynamics, phase-field modeling, and uncertainty quantification
Mohamed AbdulHameed, Fadel M. Nasr, Wen Jiang +2
Grain growth kinetics and grain-boundary (GB) properties in uranium mononitride (UN) are investigated through an integrated multiscale framework combining molecular dynamics (MD),…
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…
Modeling oxygen-void interactions in uranium nitride
Mohamed AbdulHameed, Anton J. Schneider, Benjamin Beeler +1
Oxygen impurities in uranium nitride (UN) are reported to influence its swelling behavior under irradiation, yet the underlying mechanism remains unknown. In this work, we develop…
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…
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…
A Methodology for CHF Prediction in VVER Rod Bundles
Mohamed AbdulHameed, Aly Shaaban, Hussein Gamal +1
The critical heat flux (CHF) is an important thermal-hydraulic parameter that must be determined during the design of water-cooled reactors to ensure safety of operation. In this p…
