Content:
evision 5 – July 2014 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 define mean material properties and their variability needed to support conclusions derived from the analyses. 8. The liquefaction potential (Subsection 2.5.4.8) and consequences of liquefaction of all subsurface soils, including the settlement of foundations. These analyses are based on soil properties obtained by proper and state-of-the-practice 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 applicant’s technical submittal. These are summarized and cross-referenced in this subsection. 10. The results of investigations and analyses conducted to determine foundation stability, deformation and settlement under static and dynamic conditions (Subsection 2.5.4.10). This part of the staff review also includes evaluation of necessary foundation stability monitoring programs, such as long term settlement monitoring program, to verify the design and analysis results and to ensure that static and dynamic stability design requirements are met over the life of the plant. 11. Criteria, references, and design methods (Subsection 2.5.4.11) used in static and seismic analyses of foundation materials, including an explanation of computer programs used in the analyses and soil loads on subsurface facilities. 12. Techniques and specifications to improve subsurface conditions (Subsection 2.5.4.12), which are to be used at the site to provide suitable foundation conditions. Additional information on foundations is covered in SRP Section 3.8.5 and should be
