Content:
ometry, length, sense of movement, amount of offset, age of latest movement, and limits of the fault zone are given for each fault. Investigations are to extend at least 5 miles beyond all plant sites adjacent to large bodies of water such as oceans, rivers, and lakes. Subsection 2.5.3.7. In meeting the requirements of Reference 3, this subsec- tion is judged acceptable if the zone designated by the applicant as requiring detailed faulting investigation is consistent with the description of such a zone described in Reference 3. 2.5.3-3 Rev. 2 - July 1981 Subsection 2.5.3.8. In meeting the requirements of References 1, 2, and 3, this subsection must be presented by the applicant if the aforementioned inves- tigations reveal that surface displacement must be taken into account. No commercial nuclear power plant has been constructed on a known capable fault and it is an open question as to whether it is feasible to design for surface or near-surface displacement with confidence that the integrity of the safety- related features of the plant would remain intact should displacement occur. It is, therefore, staff policy to recommend relocation of plant sites found to be located on capable faults as determined by the detailed faulting investiga- tion. If in the future it becomes feasible to design for surface faulting, it will be necessary to present the design basis for surface faulting and supporting data in considerable detail. III. REVIEW PROCEDURES The staff review procedure involves an evaluation to determine that the appli- cant has followed the investigations outlined in Reference 3. Consultants/ advisors assist the staff in reviewing this section of the SAR, on a case-by-case basis. On request, the advisor/consultant provides expertise in numerous earth science disciplines and occasionally is able to provide first-hand knowledge of the site. A literature search is conducted concerning the regional and local geology. The staff also utilizes state geological surveys
