We report on the development of new CW SRF systems for the colliding rings of a proposed electron-ion collider (EIC) at Jlab. Jefferson Lab is developing new strongly HOM-damped SRF cavities for the ion collider ring and a high-energy electron cooler at 952.6 MHz. The baseline design JLEIC will re-use the PEP-II 476 MHz cavities for the electron ring with a possible future upgrade to 952.6 MHz SRF cavities at a later date. We discuss the design optimization of the new high current cavities and compare options for the strong HOM damping required. A concept for a modular cryostat to house these various cavities will be shown, and an overview of the challenging high-level parameters will be presented. These designs and concepts may be useful in other high current storage rings and ERLs.
