REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of properties and stability of soil, and rock supporting foundations Secondary - None I. AREAS OF REVIEW Chapter 2 of the Standard Review Plan (SRP) discusses the site characteristics and parameters 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), early site permit (ESP), or combined license (COL) concerning the characteristics and stability of the soil and rock underlying the site that could affect the safe design and siting of the plant. The staff reviews information presented by the applicant for a design certification (DC) to determine if the postulated site parameters for the design, with respect to stability of the soil and rock underlying the site, are correctly identified, are representative of a reasonable number of sites that has been or may be considered for a COL application, and are appropriately justified.. 2.5.4-2 Revision 5 – July 2014 This SRP section applies to reviews performed for each of these types of applications. The review covers the following specific areas: 1. Geologic features and characteristics of materials (Subsection 2.5.4.1) at the site, specifically: A. The potential for surface and subsurface deformation is evaluated in detail in Section 2.5.3 of the applicant’s technical submittal. This potential is summarized and cross-referenced in this subsection B. Zones of alteration or irregular weathering profiles, and zones of structural weakness. 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, solubility, consolidation properties, water content, or potentially undesirable response to seismic or other events. E. Rock mass containing voids, karsts, and other discontinuities located or oriented such that instabilities or strength reduction
