q REPORT ON THE SITE SEISMICITY FOR
'd ~
TH E CRYSTAL RIVER NUCLEAR PLANT, FLvRIDA At the request of the Division of Reactor Licensing of the Atomic Energy Commission, the Seismology Division of the Coast and Geodetic Survey has evaluated the seismicity of the area around the proposed re-actor site near Crystal River, Citrus County, Florida, and has reviewed a similar analysis made by the applicant and presented in the "Prelimi-nary Safety Analysis Report." The applicant's report on the site seis-micity is adequate for an evaluation of the seismic factor.
In reviewing the seismicity, the dominant factor considered was the Charleston, South Carolina, earthquake of 1886 The response of the area around the proposed reactor site to this earthquake has been eval-uated at intensity VI. No other seismic activity has generated a higher intensity.
B ased upon the review of the site seismicity, geology and ground con-ditions, the Coast and Geodetic Survey recommends that an acceleration of 0.05 g would be adequate for representing earthquake disturbances likely to occur within the lifetime of the facility. In addition, the Survey recommends an acceleration of 0.10 g to represent the ground motion from the maximum earthquake likely to affect this site. It is believed that this value would provide an adequate basis for designing protection against the loss of function of components important to safety.
