Landslide Mitigation Strategies

Risk Assessment. The assessment identifies areas of higher landslide risk. At a minimum it uses geographic data related to slopes, geology, and the location and extent of historic landslides. The location of springs and vegetation type may also be useful data to include. The assessment should be open to the public and participatory.

Backgrounder on Seismic Reviews at U.S. Nuclear Power Plants

NRC regulations set out design, operation, and maintenance requirements for a nuclear plant's safetysignificant structures, systems, and components to keep working after most earthquakes. Plants use traditional engineering practices to add "safety margin"beyond those requirements. The NRC ensures its requirements are satisfied through the licensing, reactor oversight, and enforcement processes. In the early 2000s the NRC received new reactorrelated applications that included updated seismic information and analysis methods. The agency in 2005 began looking broadly at potential changes in earthquake hazards in the Central and Eastern United States (CEUS). Through this effort, the NRC, the Department of Energy and the Electric Power Research Institute developed an updated model for CEUS earthquake sources. This work was later incorporated into the NRC's efforts to implement the lessons learned from the accident at Fukushima Daiichi.

The NRC requires that everything in a U.S. reactor that can support a safety function must be designed according to: 1. the most severe natural phenomena historically reported for the site and surrounding area. This includes a margin for error to account for imprecise historical data2. appropriately combining the natural event with the effects of the plant's normal and accident conditionsand 3. the importance of the safety functions. An earthquake's energy spreads out from the fault and moves the ground, as well as nuclear power plant structures on or in the ground. The movement's strength and type depends on how the earthquake releases energy and on how the soil around a plant absorbs (or dissipates) the energy. Earthquakes can be measured by both the frequency of the shaking and how strongly the ground accelerates, or moves at the plant. Different frequencies and strengths affect the plant's buildings as well as the systems and components inside. An earthquake energy's frequen

Each operating U.S. nuclear power plant determined its expected ground motions with sitespecific information from historical earthquake catalogs and examination of local geology. Plant designers examined earthquake sources near a site. They used the largest quake from that sample to determine the site's expected ground motion. The NRC also used the Individual Plant Examination of External Events Program to have existing plants examine potential vulnerability to larger earthquakes. This examination focused on the plants'available safety margins to ensure these margins, together with the plant's accident management programs, continue to protect public health and safety. These "deterministic"approaches has been replaced with "probabilistic"analysis, which examines how all seismic sources and earthquake types can affect a site. This approach estimates how likely a given ground motion level is for a certain time period (such as the operating life of a reactor). The studies might conc

The CEUS is generally an area of low to moderate earthquake hazard with few active faults in contrast to the western United States. Even so, in 18111812, three major earthquakes (Magnitude 7 to 7.7 on the commonly used Richter Scale) shook much of the CEUS. These earthquakes occurred near the town of New Madrid, Mo. In 1886, a large earthquake (Richter Scale magnitude of about 7) occurred near Charleston, S.C. This earthquake caused extensive damage and was felt in most of the eastern United States. Geologists are aware of these historic occurrences, and knowledge of such earthquakes was taken into account in plant design and analysis. The NRC regularly reviews new information on earthquake source and ground motion models. For example, the NRC reviewed updated earthquake information provided by applicants in support of Early Site Permits for new reactors. This additional information included new models to estimate earthquake ground motion and updated models for earthquake sources i

The NRC began assessing the safety implications of increased plant earthquake hazards in the CEUS through a May 26, 2005, memorandum (available under Accession No. ML051450456 in the NRC Agencywide Documents Access and Management System) in which the staff recommended examining the new CEUS earthquake hazard information under the Generic Issues Program. The NRC staff identified the issue as GI199 in a e 9, 2005, memorandum (ADAMS Accession No. ML051600272) and completed the screening analysis for the issue in uary 2008. The staff then assessed available earthquake data and models. The GIP confirmed that operating nuclear power plants were operating safely. The assessment also found that, although still small, some seismic hazard estimates have increased and warrant further attention. In tember 2010, the NRC issued a Safety/Risk Assessment report (ADAMS Accession No. ML100270582) and an Information Notice (ADAMS Accession No. ML101970221) to inform stakeholders of the Safet

Following the events in ch 2011 at Japan's Fukushima Daiichi plant, the NRC considered how best to incorporate lessons from Fukushima into consideration of U.S. seismic issues. In February 2012, the NRC, DOE and EPRI completed years of CEUS research by publishing an updated understanding of that region's seismic sources. Shortly afterward, the NRC asked all U.S. nuclear power plants to develop a new ground motion response spectrum, or "hazard curve."Western U.S. plants had to develop sitespecific source models, while CEUS plants used the regional model. The plants compared the new hazard curve to their license's original safe shutdown earthquakeif the new hazard was greater, additional actions were required. These actions could include examining if any immediate actions were necessary, determining seismic effects on spent fuel pools, and/or a detailed seismic risk evaluation. The detailed risk evaluations, where appropriate, are underway, and the NRC staff will review the ev
