ight conduct an independent geologic reconnaissance of the site region, vicinity, area, and location as necessary to examine soil and rock samples from core borings and test pits and geologic features in trenches and excavations for other facilities. 3. Review of Supplemental Information The final phase for resolving all open safety-related issues is associated with the staff review of the applicant’s responses to RAIs. If the RAI response does not adequately answer the staff’s concern, staff typically will develop supplemental RAIs and request a meeting with the applicant to discuss the technical details of the remaining issues regarding site suitability and the safe operation of the proposed facility. When safety issues have been resolved, the staff then prepares the Final Safety Evaluation Report (FSER). 4. Geologic Mapping License Condition Under the COL, or ESP approach defined in 10 CFR Part 52, a license might have already been granted to an applicant before safety-related excavations are opened and geologic mapping of the excavations begun. Thus, new geologic features might be discovered in plant excavations, which have the potential to affect staff’s understanding of site safety. To ensure that the safety implications of new information are reviewed, clear statements must be provided in the site-specific portion of the COL application that the applicant commits to: (1) Perform detailed geologic mapping of the excavations for safety-related structures; (2) Examine and evaluate geologic features discovered in excavations for safety-related structures; and (3) Notify the NRC once excavations for safety-related structures are open for inspection by NRC staff. Staff propose a geologic mapping license condition in the SER for each COL site where plant excavations and geologic mapping have not been completed prior to a license being granted. Likewise, a geologic mapping license condition will be proposed in the SER for each ESP site. For those COL or ESP
