The corrosion mechanism known as flow accelerated corrosion (FAC), which results in piping wall thinning, is brought on by a confluence of physical, chemical, and hydrodynamic variables. To account for local and non-uniform distribution flow and mass transport characteristics, this phenomenon demands prediction and modelling. The CFD programme FLUENT makes this possible. In several nuclear reactors, a feeder wall thing rate of 0.1084 mm/EFPY has been recorded. Two goals are the main focus of this investigation. The first step was to use FLUENT to do a CFD study. The feeder channel of a typical reactor was modelled since it showed a maximum wall thinning rate of 1.1 mm annually. However, this experiment did not take into account the working fluid's chemical treatment. Experimental studies of FAC were carried out at a variety of temperatures to determine the FAC threshold temperature. Due to experimental limitations, no significant FAC was found for water temperatures up to 90°C.
