Content:
n the 32 safety analyses, how the test data is enveloped for design, why the design envelope is conservative and present a table indicating the value of the parameters used in the analyses. Subsection 2.5.4.3. In meeting the requirements of References 2, 3, 6, and 7 and the regulatory positions of References 8, 10, and 11, the discussion of the relationship of foundations and underlying materials is acceptable if it includes: 1. A plot plan or plans showing the locations of all site explorations, such as borings, trenches, seismic lines, piezometers, geologic profiles, and excavations with the locations of the safety-related facilities superimposed thereon. 2. Profiles illustrating the detailed relationship of the foundations of all seismic Category I and other safety-related facilities to the subsurface materials. 3. Logs of core borings and test pits. 4. Logs and maps of exploratory trenches in the application for an early site permit or combined license (COL). preliminary safety analysis report (PSAR), and A supplemental report providing geologic maps and photographs of the excavations for the facilities of the nuclear power plant should be provided when available in the final safety analysis report (FSAR).33 Subsection 2.5.4.4. In meeting the requirements of References 1, 2, 6, and 7 and the regulatory positions of References 10 and 11, the presentation of the dynamic characteristics of soil or rock is acceptable if geophysical investigations have been performed at the site and the results obtained therefrom are presented in detail. Completeness of the presentation is judged by whether or not the exploratory techniques used by the applicant yield unambiguous and useful information, whether they represent state-of-the-art exploration methods (Refs. 10, 13, 14, and 17), and whether the applicant's interpretations are supported by adequate field records in the SAR.
