  This Conceptual Design Report addresses the site-specific issues associated
with the deployment of the IsoDAR experiment at the Yemilab site.
IsoDAR@Yemilab pairs the IsoDAR cyclotron-driven $\bar{\nu}_e$ source with the
proposed Liquid Scintillator Counter (LSC) 2.5 kton detector. This document
describes the proposed siting: requirements for the caverns to house the
cyclotron, beam transport line, and target systems; issues associated with
transport and assembly of components on the site; electrical power, cooling and
ventilation; as well as issues associated with radiation protection of the
environment and staff of Yemilab who will be interfacing with IsoDAR during its
operational phases. The onset of construction of the IsoDAR area at Yemilab, in
tandem with the release of this design report, represents a key step forward in
establishing IsoDAR@Yemilab.
