Geophysics as related to siting of nuclear power plants
The safe siting of nuclear power plants requires knowledge of foundation conditions and faulting. Geophysical surveys and measurements are necessary to provide needed data in the early stages of a siting program, in order to supplement geologic studies. Later, detailed licensing studies may require additional geophysical measurements to supplement geotechni-cal engineering studies.
Seismic methods are most commonly used for exploring localized geologic and foundation conditions at and near a plant site; gravity and magnetic measurements are often helpful in regional geologic studies.
Other geophysical exploration techniques are usually reserved for specialized applications such as the search for subsurface cavities, determination of stratigraphy, slope stability studies, hydrogeology, and locating construction materials. Special seismic techniques are employed to determine dynamic elastic properties.
Figures & Tables
During the “great decade” of siting and construction of nuclear power plants that ended in 1975, the nuclear industry mustered the largest geologic task force in this country’s history, resulting in rapid advances in geologic technologies. Many of the advances are discussed in this volume, a major contribution to engineering geology. Subjects treated are the regulatory, siting, and licensing processes; seismicity of the central and western U.S., with a consumer’s guide to instrumental methods for determination of hypocenters; and techniques, such as remote-sensing, microfacies analysis, dating techniques in faults, trenching as an exploratory method, borehole geophysics, and ground-water studies. Includes a useful glossary.
