se consult- ants. Consultants are asked to handle such varied tasks as reviewing the tec- tonic setting of plants in regions of complex geology, evaluation of the poten- tial for surface displacement, verifying an applicant's mineral identifications, or providing advice on the proper level of earthquake ground motion (response spectrum) to be used (based on state-of-the-art studies) in the seismic evaluation of selected sites. -After docketing, a detailed review of the SAR and relevant references is con- ducted by the staff and its advisors. Questions and comments are developed from items that have not been adequately addressed by the applicant, those which become apparent during the detailed review, or those which develop from the additional information provided as a result of the acceptance review. These questions (Q-1) usually require the applicant to conduct additional investiga- tions or to supply clarifying information. Many questions result from the reviewer's discovery of references not cited by the applicant that contain con- clusions which are in conflict with those made by the applicant. When the applicant provides insufficient data to support his interpretations and conclu- sions, and there are reasonable and more conservative alternative interpreta- tions in the literature, the staff will request additional investigations. This phase of the review will usually involve meetings with the applicant to clarify questions and allow him to present new data. In addition, during the Q-1 phase of the construction permit review, the staff visits the site. The applicant's responses to Q-1 questions are reviewed and any remaining issues are settled either by additional questions (Q-2) or by staff positions (RSP). 2.5.1-5 Rev. . 2 - July 1981 A staff position is usually in the form of a requirement to design for a specific condition in a way which the staff considers to be sufficiently conservative and consistent with the requisites of Reference 3.
