ABSTRACT

Tsunami Hazard Assessment at Nuclear Power Plant Sites in the United States of America: Final Report   [open pdf - 3MB]

"We describe the tsunami phenomenon with the focus on its relevance for hazard assessment at nuclear power plant sites. Chapter 1 includes an overview of tsunamis and mechanisms that generate tsunamis. Three tsunamigenic mechanisms--earthquakes, landslides, and volcanoes--are considered relevant for hazard assessment at nuclear power plant sites. We summarize historical tsunami occurrences, including descriptions of source mechanisms and damages caused by these events. Historical landslides and potential landslide areas in earth's oceans are described. We describe the hierarchical-review approach to tsunami-hazard assessment at nuclear power plant sites in Chapter 2. The hierarchical-review approach consists of a series of stepwise, progressively more-refined analyses to evaluate the hazard resulting from a phenomena at a nuclear power plant site. [...]. Chapter 3 describes the effects tsunami waves may have at a nuclear power plant site. These effects result in hazards that may directly affect the safety of a plant's structures, systems, and components. [...]. Chapter 4 describes data required for a detailed tsunami-hazard assessment and sources of these data. We recommend using existing resources and previously completed tsunami-hazard assessments, if available and appropriate. [...]. Chapter 5 defines the probable maximum tsunami, its determination at a site, and subsequent hazard assessment. We point out that a tsunamigenic source that produces probable maximum tsunami hazards at a site may not be determined a priori. [...]. Chapter 6 describes international practices by Japan and the International Atomic Energy Agency, which are reviewed for completeness. The appendix provides a stepwise guide to site-independent analyses for tsunami-hazard assessment."
