The selection of a site and the development of geologic and seismic design parameters may be facilitated through the use of a three-phase program of investigation. This program is cost effective and expedites management decisions that benefit from current relevant geologic information. A resource review and regional reconnaissance during Phase I serve to eliminate areas of low potential, to focus on favorable areas, and to identify possible problems that may require further study. Preliminary estimates of certain design parameters during Phase I may be used to initiate contract negotiations with a plant supplier. Candidate sites and associated problems can then be examined through analysis of large-scale maps and imagery, preliminary geologic mapping, and subsurface investigation during Phase II. Phase II may lead to preparation of an Early Site Review Report (ESRR) for submission to the Nuclear Regulatory Commission (NRC). A Phase III investigation leading to the preparation of a Preliminary Safety AnalysisrReport (PSAR) can be performed concurrently or sequentially on any or all candidate sites recommended at the conclusion of Phase III.
This approach is illustrated with examples from Spain and Iran showing how such a program assists in selection and study of possible sites.

Geology in the Siting of Nuclear Power Plants
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.
