Abstract

Abstract

En 中文
• A machine learning interatomic potential (MLIP) was developed to determine the thermophysical properties of NaCl-UCl3 molten salts with near ab initio accuracy across the full compositional range. • The calculated thermophysical properties of NaCl-UCl3 melts are directly relevant to the molten salt reactor design and other nuclear engineering applications. • Oligomerization of UCl species dictates the thermophysical properties of NaCl-UCl3 at different compositions. • NaCl acts as a spacer salt that disrupts the U-Cl-U network and modifies the thermophysical properties of NaCl-UCl3 melt.
