Evaluation of the response of equipment at the El Centro Steam Plant to the October 15, 1979 Imperial Valley, California earthquake

Technical Report ·
OSTI ID:6885320
In October of 1979, the four-unit power plant at El Centro, California, experienced an earthquake of Magnitude 6.6 on the Richter scale. A ground motion record was taken at the plant site, allowing accurate estimates of the seismic motion experienced by the plant structures and the equipment contained inside. As part of a research program sponsored by the Seismic Qualification Utilities Group, a series of in-situ tests were conducted on equipment in the plant. The measurements of equipment response frequencies which resulted from the tests allowed estimates to be made of the seismic loads that the equipment experienced during the 1979 earthquake. The general resistance of the El Centro Plant equipment to these seismic loads provides data on the probable seismic capacity of similar equipment in nuclear power plants.
