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…
Lattice anharmonicity effects in fluorite oxide single crystals and anomalous increase in phonon lifetime in ceria at elevated temperature
Amey Khanolkar, Saqeeb Adnan, Md Minaruzzaman +6
We investigate the temperature dependence of the frequency and linewidth of the triply-degenerate T zone-centered optical phonon in flux-grown ceria and hydrothermally-synth…
Engineering Phonons in Compositionally Complex Carbide Ceramics
Linu Malakkal, Jarin C French, Lanh Trinh +6
In the pursuit of advanced ceramic materials with exceptional irradiation-resistance and high-temperature tolerance for nuclear applications, compositionally complex carbides (CCCs…
Machine learning interatomic potential for predicting the thermal properties of uranium nitride
Beihan Chen, Zilong Hua, Jennifer K. Watkins +4
We present a combined computational and experimental investigation of the thermal properties of uranium nitride (UN), focusing on the development of a machine learning interatomic…
Experimental Confirmation of First-Principles Thermal Conductivity in Zirconium-Doped ThO
Ella Kartika Pek, Zilong Hua, Amey Khanolkar +7
The degradation of thermal conductivity in advanced nuclear fuels due to the accumulation of fission products and irradiation-induced defects is inevitable, and must be considered…
Xenon-metal pair formation in UO2 investigated using DFT+U
Linu Malakkal, Shuxiang Zhou, Himani Mishra +4
A recent experimental study on a spent uranium dioxide (UO2) fuel sample from Belgium Reactor 3 (BR3) identified a unique pair structure formed by the noble metal phase (NMP) and f…
Phonon modal analysis of thermal transport in ThO2 with point defects using equilibrium molecular dynamics
Beihan Chen, Linu Malakkal, Marat Khafizov +2
Defects can significantly degrade the thermal conductivity of ThO2, an advanced nuclear fuel material as well as a surrogate for other fluorite-structured materials. We investigate…
First-principles determination of the phonon-point defect scattering and thermal transport due to fission products in ThO2
Linu Malakkal, Ankita Katre, Shuxiang Zhou +4
This work presents the first principles calculations of the lattice thermal conductivity degradation due to point defects in thorium dioxide using an alternative solution of the Pi…
