Nuclear Power Plant Sites: Maps of Seismic Hazards and Population Centers [March 29, 2011] [open pdf - 506KB]
"Currently, 104 commercial nuclear power plants operate on 64 sites in the 48 contiguous United States. Sixty-nine of the 104 are pressurized water reactors (PWR) and the 35 remaining are boiling water reactors (BWR). The PWR plants are based on Babcock & Wilcox, Combustion Engineering, and Westinghouse designs. The BWR plants are based on a series of General Electric designs. The Nuclear Regulatory Commission (NRC) has received 28 Combined License (COL) applications for new reactors based on advanced reactor designs (Table 2). Three COL applications will involve new sites. CRS determined the coordinates of plant sites using web-based applications and overlaid the sites on base maps of: 1. Quaternary faults, 2. Seismic hazards in terms of percent gravitational acceleration, 3. Levels of horizontal ground shaking (gravitational acceleration) that have a 2-in- 100 (2%) probability of being exceeded in a 50-year period, and 4. Metropolitan populations To map the proximity of plant sites to faults (Figure 1), CRS referred to the USGS Quaternary Fault and Fold Database of the United States. This database contains information on faults and associated folds in the United States that are believed to be sources of greater than magnitude 6 (M>6) earthquakes during the Quaternary (the past 1,600,000 years). It is important to note that this map is not a prediction of an earthquake event."
