This study identifies and categorizes the human and organizational factors relevant to a multi-unit incident scenario of NPPs based on a review of relevant literature. These factors are then analyzed to ascertain all possible unit-tounit interactions that need to be considered in the multi-unit HRA and the pattern of interactions. | Human and organizational factors for multi-unit probabilistic safety assessment: Identification and characterization for the Korean case Nuclear Engineering and Technology 51 (2019) 104e115 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: Original Article Human and organizational factors for multi-unit probabilistic safety assessment: Identification and characterization for the Korean case Awwal Mohammed Arigi, Gangmin Kim, Jooyoung Park, Jonghyun Kim* Department of Nuclear Engineering, Chosun University, 309 Pilmun-daero, Dong-gu, Gwangju, 501-709, Republic of Korea a r t i c l e i n f o a b s t r a c t Article history: Since the Fukushima Daiichi accident, there has been an emphasis on the risk resulting from multi-unit Received 21 March 2018 accidents. Human reliability analysis (HRA) is one of the important issues in multi-unit probabilistic Received in revised form safety assessment (MUPSA). Hence, there is a need to properly identify all the human and organizational 20 July 2018 factors relevant to a multi-unit incident scenario in a nuclear power plant (NPP). This study identifies and Accepted 29 August 2018 Available online 7 September 2018 categorizes the human and organizational factors relevant to a multi-unit incident scenario of NPPs based on a review of relevant literature. These factors are then analyzed to ascertain all possible unit-to- unit interactions that need to be considered in the multi-unit HRA and the pattern of interactions. The Keywords: Multi-unit PSA human and organizational factors are classified into five categories: organization, work device, task, Unit-to-unit interaction performance shaping factors, and environmental factors. The identification and classification of these Multi-unit HRA factors will significantly contribute to the development of adequate strategies and guidelines for man- Human and .
