The goal of this work is to assess potential runaway electron first wall impacts in the SPARC tokamak (Bt=12.2T, Ip=8.7MA), which is currently being built by Commonwealth Fusion Systems for demonstration of fusion gain Q>1. A simple analytical model is used to identify the operational plasma currents where runaway electrons could cause wall melting, and a threshold of around 1MA is where runaway impacts may start to cause concern, depending on the wetted area. Runaway electrons have been implemented into the simulation code HEAT[^1] to calculate the trajectory, energy deposition, and resulting plasma facing component temperatures from runaway electron impacts. Preliminary simulation results are shown. This work is supported in part by Commonwealth Fusion Systems.
