Evaluation of Evacuation Strategies According to the Travel Demand: The Case of Nuclear Research Reactor HANARO’s EPZ

Abstract

In the event of a nuclear accident, evacuation is the most effective protective action for the public. During the evacuation, total travel time is a key measure to protect the public because it is directly related to the public’s radiation exposure. Thus, strategies that reduce the total travel time are needed for a safer nuclear emergency plan. Many studies on evacuation strategies so far have suggested the methodology of effective routing decisions or delay management. Despite the application of those strategies during evacuation, the effectiveness of those strategies, in reality, varies depending on the level of travel demand. In this study, evacuation strategies based on travel demand levels were evaluated based on the case of the Emergency Planning Zone (EPZ) of HANARO, the nuclear research reactor in the Republic of Korea. As a result, it was confirmed that effective evacuation strategies could be applied differently according to travel demand levels.

Enhancing Radiological Emergency Response through Agent-Based Model Case 2: Time Required for Staff Assemble

“…[1] In the aftermath of such incidents, substantial focus has been placed on evacuation strategies, with numerous studies aiming to optimize evacuation processes and accurately predict evacuation times. [2][3][4] However, while the evacuation of general public is crucial, equally important is the rapid assembly of emergency staff required to stabilize the affected nuclear power plant. Recognized within South Korea's Accident Management Program [5], the guidelines specify that emergency staff assembly must be completed swiftly to ensure effective incident management.…”
