About the Lab
Professor Hyeungjoon Kim's research lab focuses on enhancing nuclear safety through systematic risk assessment and human factors analysis in nuclear energy systems. The lab specializes in human reliability analysis (HRA), team performance evaluation in digital control rooms, and safety frameworks for nuclear power plant decommissioning, particularly addressing radiation risks and human-machine interaction. It also conducts probabilistic safety assessments (PSA) for external events such as extreme natural disasters, integrating structural vulnerability analysis and failure mode evaluation to improve resilience. The lab’s work bridges engineering, human factors, and risk modeling to support safer nuclear operations across the plant lifecycle.

4A team of operators is required for nuclear power plant operation, and communication between the operators is an important aspect of the team's ability to successfully carry out tasks. It has been difficult to evaluate the quality of this communication though, and as the relationship between communication quality and team performance has yet to be clarified, it has not been applied to most human reliability analysis (HRA) methodologies. This study investigates the relationship between the qualit
Considering that the nuclear power plants have a licensed lifetime, the need for research on decommissioning is increasing along with the number of aging plants globally. Unlike the dismantling of other buildings, the decommissioning of a nuclear power plant involves radiation risk, which necessitates a new systematic safety assessment to reduce this risk. This paper proposes a framework for the safety assessment of workers in nuclear power plant decommissioning. The first step of the process is
Considering the climate change, a new analysis is needed for external events related to natural disasters on nuclear power plants.In the case of extreme natural disasters such as tsunamis and earthquakes, the consequences of accidents will be very serious.After screening and analysing the natural disasters affecting the nuclear power plant, the nuclear power plant structure and components affected by the selected natural disasters are derived through the nuclear power plant walkdown.After the fa
