- RAON will be the only accelerator complex in the world that has both Isotope Separation On-Line (ISOL) and In-flight
Fragmentation (IF) for the production of various rare isotopes. Since accelerators are defined as radiation generating
devices, strict operate procedures and safety assurance are required to prevent radiation exposure. To satisfy this condition, there is a need for evaluating potential risks of the accelerator facility from the design stage itself. Radiation generating devices, e.g., accelerators are one of the types of non-reactor nuclear facilities where PRA can be of benefit. The objective of this study is to conduct accident sequence analysis for the accelerator facility using the PRA approach. The analysis embraces identification of initiating events, system analysis, and accident sequences development. As RAON is in the design stage where various configurations are under consideration now, only qualitative accident sequence analysis was conducted.
When the detailed design is finalized, quantitative accident sequence analysis will be conducted.
