Developing an Integrated Model of Resilience and System Dynamics for NPP Accident

The Fukushima Daiichi nuclear power plant (FDNPP) accident highlights the role of resilience and system dynamics in maintaining the safety of nuclear power plants (NPP). A brief literature review is conducted regarding the FDNPP accident, and an integrated model of resilience and system dynamics (IMRSD) for an NPP accident is proposed. This IMRSD is developed based on four key elements of resilience: anticipating, monitoring, responding, and learning. These elements are influenced by thirteen factors. The identified factors in the proposed model are requisite imagination regarding expected initiating event, the organizational safety culture, the proper human resource with adequate training, the requisite interpretation regarding the progress of the event, the monitoring procedures during the accident, the proper support from the human resources, the proper system to notice the developments of the accident, the adequate resources, the responding procedures, the availability of flexibility of responses, the trained personnel for emergency responses, experiences from the past events and responses, proper modeling of accident and analyzing natural hazard. Responding is found as the most vital element for effective resilience in the event of an NPP accident. Decision-makers of operating management at an NPP can consider the identified factors and how they interact with various elements to ensure the safety of NPPs.
