Content:
stability of all safety-related facilities has been analyzed from a static stability standpoint including bearing capacity (Ref. 22), rebound, settlement, and differential settlements (Ref. 23) under deadloads of fills and plant facilities, and lateral loading conditions. The bearing capacity estimates must include consideration of settlements associated with the strength estimates. Field and laboratory test procedures and results must be included to document soil and rock properties used in the analyses. The applicant must show that the methods of analysis used are appropriate for the local soil conditions and the function of the facility. 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: A. Determining whether or not the soil and rock properties used in the analyses represent the actual site conditions beneath the planned locations of plant facilities. The site investigation, sampling, and laboratory test programs must be adequate for this evaluation. B. Determining whether or not the methods of analysis are appropriate for the planned earthworks, foundations, and soil conditions at the site. C. Determining whether or not the bearing capacity, settlement, differential settlement, and tilt estimates indicate conservative and tolerable behavior of the planned plant foundations when these values are compared to design criteria and quality assurance specifications. D. Evaluation of particularly complex cases on the basis of accepted principles and techniques as supplemented by case histories and confirmatory measurement and analysis programs. 11. 2.5.4.11 - Design Criteria. In meeting the requirements of 10 CFR Part 50, the discussion of criteria and design methods is acceptable if the criteria used for the design, the design methods employed, and the factors of safety
