Content:
the nuclear power plant. 2. Plans for dewatering during construction. 3. Analysis and interpretation of seepage and potential piping conditions during construction. 4. Records of field and laboratory permeability tests. 5. History of groundwater fluctuations as determined by periodic monitoring * .of local wells and piezometers. Flood conditions should also be considered. Subsection 2.5.4.7. In meeting the requirements of References 2, 3, 4, 6, and 7 and the regulatory positions of References 10 and 11, descriptions of the 1 response of soil and rock to dynamic loading are acceptable if: 1. An investigation has been conducted and discussed to determine the effects of prior earthquakes on the soils and rocks in the vicinity of the site. Evidence of liquefaction and sand cone formation should be included. 2. Field seismic surveys (surface refraction and reflection and in-hole and ~' cross-hole seismic explorations) have been accomplished and the data presented and interpreted to develop P and S wave velocity profiles. 3. Dynamic tests have been performed in the laboratory on samples of the foundation soil and rock and the results included. The section should be cross-referenced with Subsection 2.5.2.5. 2.5i.4-7 Rev. 2 - July 1981 The soil-structure interaction analysis should be described in SRP Sections 3.7.1 and 3.7.2 and cross-referenced to this subsection. In the soil-structure interaction analysis, the following parameters are reviewed: a. The static and dynamic properties of the soil supporting the structure are properly determined and compatible with the characteristics of the analytical model used to evaluate soil-structure interaction effects. b. The soil profile has been properly modeled when a two-dimensional finite- element analysis is used, or if a half-space analysis method is used, when foundation moduli and damping are consistent with soil properties and soil profiles at the site. c. The static and dynamic loads, and the stresses and strains induced
