Content:
y cooling water source is of particular interest with regard to slope stability (Refs. 4 and 8). The secondary source of emergency cooling water should survive the operating basis earthquake (OBE) and design basis flood. Completeness is determined by the ability to make an independent evaluation on the basis of information provided by the applicant. Specific criteria necessary to meet the relevant requirements of the Commission regulations identified above are as follows: 2.5.5-5 DRAFT Rev. 3 - April 1996 Subsection 2.5.5.1. In meeting the requirements of References 3, 4, and 6 and the regulatory positions contained in References 8, 10, and 11, the discussion of slope characteristics is acceptable if the subsection includes: 1. Cross sections and profiles of the slope in sufficient quantity and detail to represent the slope and foundation conditions. 2. A summary and description of static and dynamic properties of the soil and rock comprising comprised by seismic Category I embankment dams and their foundations, 22 natural and cut slopes, and all soil or rock slopes whose stability would directly or indirectly affect safety-related and Category I facilities. The text should include a complete discussion of procedures used to estimate, from the available field and laboratory data, conservative soil properties and profiles to be used in the analysis. 3. A summary and description of groundwater, seepage, and high and low groundwater conditions. Subsection 2.5.5.2. In meeting the requirements of References 1, 2, 3, 6, and 7 and the regulatory positions of Reference 8, the discussion of design criteria and analyses is acceptable if the criteria for the stability and design of all seismic Category I slopes are described and valid static and dynamic analyses have been presented to demonstrate that there is an adequate margin of safety. A number of different methods of analysis are available in the literature. Computer analyses should be verified by manual methods. Analysis
