A heavy ion accelerator called RAON is being constructed in Korea to produce various rare isotopes for the Rare Isotope Science Project (RISP). This facility is designed to use both In-flight Fragment (IF) and Isotope Separation On-Line (ISOL) techniques in order to provide a wide variety of RI beams for nuclear physics experiment. One of the biggest challenges in operating such a high beam power facility (~400 kW) is to monitor beam loss accurately and to execute the machine protection system reasonably quickly whenever necessary. In this work, we report the conceptual design of the RAON beam loss monitoring system together with the initial test results of the prototype detectors. Monte Carlo simulations using MCNPX code have been performed to generate radiation dose maps for 1 W/m losses of proton, Oxygen, and Uranium beams. The required machine protection time has been estimated from the yield time of the stainless steel beam line components including the beam grazing angle dependence. Types of the detectors have been determined based on the radiation levels of the gammas and neutrons, and the minimum sensitivity and response time requirements. *E-mail addresses: mchung@unist.ac.kr (M.
