Efficient realization of the scientific potential of the Electron Ion Collider (EIC) calls for a future second Interaction Region (2nd IR) and detector to be added in the RHIC IR8 region after the EIC project completion. The second IR and detector are needed to independently cross-check the results of the first detector, and to provide measurements with complementary acceptance. The available space in the existing RHIC IR8 and maximum fields achievable with NbTi superconducting magnet technology impose constraints on the 2nd IR performance. Since commissioning of the 2ndIR is envisioned a few years after the first IR, such a longer time frame allows more R&D for the Nb3Sn magnet technology, thus it could be a potential choice of technology for the 2nd IR magnets. Presently we are exploring potential 2nd IR performance benefits, such as luminosity and acceptance, and technical risks associated with use of Nb3Sn magnets. In this paper, we present the current progress of this work
