Considerations of the Optimized Protective Action Distance to Meet the Korean Protective Action Guides Following Maximum Hypothesis Accidents of Major KAERI Nuclear Facilities

Background: Korea Atomic Energy Research Institute (KAERI) operates several nuclear research facilities licensed by Nuclear Safety and Security Commission (NSSC). The emergency preparedness requirements, GSR Part 7, International Agency (IAEA) request protection strategy based on the hazard assessment that is not applied in Korea.Materials Methods: In developing strategy, it important to consider an accident scenario its consequence. KAERI has tried a hypothesis for major facilities. During assessment, safety analysis report of related was reviewed, simulation using MELCOR, MACCS2 code implemented considered each facility, international guidance considered.Results Discussion: results optimized protective actions were 300 m evacuation 800 sheltering High-Flux Advanced Neutron Application Reactor (HANARO), radius 50 m, 400 post-irradiation examination facility (PIEF), 100 or HANARO fuel fabrication plant (HFFP) facility.Conclusion: distances maximum postulated accidents establishing plan procedures implementing exercise
