REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of properties and stability of soil and rock Secondary - None I. AREAS OF REVIEW Chapter 2 of the SRP discusses the site characteristics that could affect the safe design and siting of the plant. The staff reviews information presented by the applicant for a construction permit (CP), operating license (OL), design certification (DC), early site permit (ESP), or combined license (COL) concerning the properties and stability of the soil and rock underlying the site that could affect the safe design and siting of the plant. This SRP section applies to reviews performed for each of these types of applications. The review covers the following specific areas: 1. Geologic features (Subsection 2.5.4.1) in the vicinity of the site, specifically: a. Areas of actual or potential surface or subsurface subsidence, solution activity, uplift, or collapse. b. Zones of alteration or irregular weathering profiles, and zones of structural weakness. 2.5.4-2 Revision 3 - March 2007 c. Unrelieved stresses in bedrock and their potential for creep and rebound effects. d. Rocks or soils that might be unstable because of their mineralogy, lack of consolidation, water content, or potentially undesirable response to seismic or other events. e. Rocks containing joint sets oriented such that instabilities in the foundation material may occur. f. History of deposition and erosion, including glacial and other preloading influence on soil deposits. g. Estimates of consolidation and preconsolidation pressures and methods used to estimate these values. 2. The static and dynamic engineering properties of soil and rock strata underlying the site (Subsection 2.5.4.2) as supported by representative field and laboratory data provided by the applicant. 3. The relationship of the foundations for safety-related facilities and the engineering properties of underlying materials as illustrated on plot plans and profiles (Subsection
