n the text, and supported by explorations for borrow material, test fills and adequate representative laboratory test records. 6. Groundwater conditions and piezometric pressure in all critical strata (Subsection 2.5.4.6) as they affect the loading and stability of foundation materials. This part of the staff review also includes an evaluation of the applicant's plans for dewatering during construction as well as groundwater control throughout the life of the plant. 7. The responses of site soils or rocks to dynamic loading (Subsection 2.5.4.7), including appropriate laboratory and field test records in sufficient number and detail adequate to support conclusions derived from the analyses. Soil-structure interaction analyses are reviewed in coordination with Structural Engineering Branch (SEB) to assure soil properties data for the soil profile model are representative of the in situ soils. 8. The liquefaction potential (Subsection 2.5.4.8) and consequences of lique- faction of all subsurface soils, including the settlement of foundations. These analyses are based on soil properties obtained by state-of-the-art laboratory and field tests and involve application of both deterministic and probabilistic procedures. 9. The earthquake design bases (Subsection 2.5.4.9) are evaluated in detail in Section 2.5.2 of the SAR. These are summarized and cross-referenced in this subsection. The safe shutdown earthquake (SSE) and the operating basis earthquake (OBE) are evaluated in this subsection in combination with other hazards (floods, etc.) to assess the adequacy of the site materials under dynamic conditions. 10. The results of investigations and analyses conducted to determine founda- tion material stability, deformation and settlement under static conditions (Subsection 2.5.4.10). 2.5.4-2 Rev. 2 - July 1981 11. Criteria, references, and design methods (Subsection 2.5.4.11) used in static and seismic analyses of foundation materials, including an explana- tion of computer
