摘要
RAON is a heavy-ion accelerator complex that is being constructed in Daejeon, Korea. The superconducting linear accelerator of RAON will provide various heavy-ion beams with a maximum power of 400 kW. In order to determine the design requirements of the underground facility for the accelerator, we considered the radiation's influence on the soil and the ground-water under the condition of long-term operation of the accelerator. A source term for prompt neutrons generated by heavy-ion beams losses along the beam lines at a rate of 1 W/m was applied to obtain the activation level of nearby material outside the tunnel by using the simulation codes MCNPX and SP-FISPACT. This report presents the analysis and the result for the tunnel shielding condition obtained from the assessment.
