REVIEW RESPONSIBILITIES Primary - Hydrologic and Geotechnical Engineering Branch (HGEB)Civil Engineering and Geosciences Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW Information must be presented by the applicant concerning the properties and stability of all soils and rock which may affect the nuclear power plant facilities, under both static and dynamic conditions including the vibratory ground motions associated with the safe shutdown earthquake. Stability of these materials, as they influence the safety of seismic Category I facilities, must be demonstrated. In addition an assessment of the properties and stability of these materials should be consistent with SRP Sections 3.7 and 3.8. Much of the information discussed in this section may be presented in other sections, in which case it may be cross-referenced rather than repeated here. The staff review covers the following specific areas: 1. Geologic features (Subsection 2.5.4.1) in the vicinity of the site: 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. c. Unrelieved stresses in bedrock and their potential for creep and rebound effects. DRAFT Rev. 3 - April 1996 2.5.4-2 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. History of deposition and erosion, including glacial and other preloading influence on soil deposits. f. 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
