Degradation of steels used in the fast nuclear reactor that using liquid metals as a
coolant material is still a major problem. Whereas, the design of the fast nuclear reactors as an
IVth generation reactor has many advantages. Many investigations have been done with the
purpose of finding the best steel alloy material and finding the best mechanism of corrosion
reduction of material. Theoretically, to predict a needed novel material and also knowing the
mechanism of corrosion inhibition, we can use computational methods as (MD) molecular
dynamics method. Using molecular dynamics, we can explore new potential materials and new
promising corrosion inhibition mechanism based on the calculated properties of materials. In
the current MD work, we study Fe-Ni-Cr performance if used in a high-temperature molten
lead liquid (coolant) and observing how this material has the possibility in fast nuclear reactor
applications. We also studied the mechanism of corrosion inhibition based on the injection of
oxygen gas into the coolant. From MD simulation we have got an important conclusion about
the FeNiCr performance that may be useful for nuclear reactor design. Degradation of steels used in the fast nuclear reactor that using liquid metals as a
