Cornell University is currently commissioning a novel, 100 mA electron injector for an energy-recovery linac based X-ray light source. Substantial wakefields will be generated by the short bunch, high current beam when it passes through the injector cryomodule, hosting five superconducting microwave cavities together with six broadband beam pipe microwave absorbers. In this paper we present wakefield and loss factor calculations for all components inside this cryomodule, including RF cavities, microwave absorbers, flanges, gate valves, and beam pipe radius transitions. The dependence on bunch length is discussed as well as a comparison of results from different numerical wakefield codes.
