The Future Circular Collider (FCC) is a design study for a staged circular collider with a circumference of about 90 km, consisting of a luminosity-frontier, highest-energy electronpositron collider (FCC-ee) followed by an energy-frontier hadron collider (FCC-hh). The FCC-ee is being designed for stored beam energies up to 17.8 MJ, a value almost two orders of magnitude higher than any previous lepton collider. Considering the risk of any beam losses causing experimental backgrounds, magnet quenches, or even damage, a halo collimation system is under study to protect the most sensitive equipment from unavoidable losses. Beam dynamics and tracking studies are key aspects to evaluate the cleaning performance of the collimation system, and are essential in an iterative process to converge on an optimum performance. The first results of such studies are presented, including estimated beam loss and power load distributions around the ring, with a particular focus on the Interaction Regions (IRs).
