Transferability of Zr-Zr interatomic potentials

open access: yesJournal of Nuclear Materials, 2023
Tens of Zr inter-atomic potentials (force fields) have been developed to enable atomic-scale simulations of Zr alloys. These can provide critical insight in the in-reactor behaviour of nuclear fuel cladding and structural components exposed, but the results are strongly sensitive to the choice of potential.
