| Identification of Superimposition Events Induced by a Combination of Seismic and Tsunami Impacts for Developing a Multi-Hazard Probabilistic Risk Assessment Method |
|---|
| Fukushima-Daiichi Nuclear Power Plant accident in March 2011 revealed the risk of the combinational hazards of seismic and tsunami at nuclear power plants (NPPs). For evaluation and improvement of the safety of NPPs against seismic and tsunami hazards, probabilistic risk assessment (PRA) methods have been developed for each hazard. However, each method focuses on the target single-hazard and ignores almost all impacts of the other hazard. For a precise risk assessment of the combination of the two hazards, a new PRA method needs to be developed that considers not only the impact of each hazard but also the impacts of their combination. This study identifies in general what kind of events can be induced by the combination of seismic and tsunami impacts at a typical NPP site faced on a coast. These events are classified based on their causes and occurring locations. How each event can be considered in PRA is briefly described. |

Bio: Eishiro Higo is a Research Scientist in the Nuclear Risk Research Center (NRRC), the Central Research Institute of Electric Power Industry (CRIEPI), Japan. He is working on studies for multi-hazard PRA and multi-unit PRA. His most recent focus is on accident sequence analysis for multi-hazard (seismic and tsunami) PRA. His other research interests include natech risk assessment, disaster risk assessment, and risk communication. He received the B.E. degree in civil engineering and the M.Eng. degree in urban management from Kyoto University, Japan, in 2010 and 2012, respectively. He received the Ph.D. degree in civil engineering from the University of Waterloo, Ontario, Canada, in 2019. Dr. Higo is a member of the Atomic Energy Society of Japan (AESJ).
