chniques used have sufficient sensitivity to identify all potential capable tectonic sources such as faults, V Xor folds associated with blind faults, within 8 km (5 mi) of the site; and "'__ when the geometry, length, sense of movement, amount of total offset, amount of offset pe'r event, age of latest and any previous displacements, recurrence, and limits of the zone are given for each capable tectonic source. Investigations are to extend at least 8 km (5 mi) beyond all plant site boundaries, including those adjacent to large bodies of water such as oceans, rivers, and lakes. Subsection 2.5.3.7 Designation of Zones of Ouaternarv Deformation in the Site Region. In meeting the requirements of Reference 2, this subsection is judged acceptable if the zone designated by the applicant as requiring detailed faulting investigation is of sufficient length and breadth to include all Quaternary deformation significant to the site (Ref. 3). Subsection 2.5.3.8 Potential for Surface Tectonic Deformation at the Site. In meeting the requirements of References 1 and 2, this subsection must be presented by the applicant if the aforementioned investigations reveal that surface displacement must be taken into account. If there is a potential for tectonically induced surface displacement at the site, it would be prudent of the applicant to abandon the site. No commercial nuclear power plant has been constructed on a known capable fault (capable tectonic source) and it is an open question as to whether it is feasible to design for tectonic 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 (capable tectonic sources) as determined by the detailed faulting investigations. If in the future it becomes feasible to U design for surface faulting, it will be necessary to
