Abstract
Materials that have superior properties are indispensable for technological applications. Steel that has strong, heat-
resistant, corrosion-resistant properties is indispensable for application in the design of liquid lead metal-cooled nuclear
reactors. One of the steels that need to be studied for superior properties is FeNi alloy steel. In this study, the influence of
FeNi steel composition was studied using computational methods of simulating molecular dynamics. The exact
composition of FeNi steel to be able to work in liquid lead reactor coolant was analyzed using the CNA (common neighbor
analysis) method. Molecular dynamics simulation uses the MOLDY program while the calculation of CNA values uses the
OVITO program. From the simulation results, it can be known the effectiveness of variations in Fe and Ni composition that
are able to produce the most stable FeNi alloy steel from the influence of liquid lead metal corrosion.
