Content:
fe shutdown and operating basis earthquakes is contained in SRP Section 2.5.2. The staff's evaluation of the amplification characteristics of specific soils and rocks beneath the site as determined by procedures discussed in that section and in Subsections 2.5.4.2, 2.5.4.4, and 2.5.4.7 are summarized and cross-referenced herein. The review of Subsection 2.5.4.9 concentrates on determining its consistency or inconsistency with other subsections. Cross-referencing with other sections is expected. Subsection 2.5.4.10. Static analyses of the bearing capacity and settlement of the supporting soils under the loads of fills, embankments, and foundations are evaluated by conventional, state-of-the-art methods (Ref. 18). In general, the evaluation procedure includes: 1. Determining whether or not the soil and rock properties used in the analyses represent the actual site conditions beneath the plant facilities. The site investigation, sampling, and laboratory test programs must be adequate for this evaluation. 2. Determining whether or not the methods of analysis are appropriate for the earthworks, foundations, and soil conditions at the site. 3. Coordinating with SEB to determine whether or not the bearing capacity, settlement, differential settlement, and tilt estimates indicate conserva- tive and tolerable behavior of the plant foundations when these values are compared to design criteria and quality assurance specifications. 4. Evaluation of particularly complex cases on the basis of accepted principles and techniques as supplemented by case histories and confirma- tory measurement and analysis programs (Ref. 18). Subsection 2.5.4.11. Criteria and design methods, including construction control and monitoring systems, are evaluated on the basis of conservative accepted practice for similar facilities. Site exploration, sampling, testing, and interpretation are judged with respect to completeness, care and technique, meaningful documentation, performance records for
