REVIEW RESPONSIBILITIES Primary - Geosciences Branch (GB) Secondary - None I. AREAS OF REVIEW GB reviews the geologic and seismic information submitted in the applicant's safety analysis report (SAR). The principal regulation used by GB in determining the scope and adequacy of the submitted geologic and seismologic information is Appendix A to 10 CFR Part 100, "Seismic and Geologic Siting Criteria for Nuclear Power Plants" (Ref. 3). Additional guidance (regulations and regulatory guides) is provided to the GB through References 1, 2, 4, and 5. GB judges the adequacy of the geologic and seismic information cited in support of the applicant's conclusions concerning the suitability of the plant site. The GB will coordinate other branch evaluations that interface with the geologic and seismologic aspects of the site as follows: Hydrologic and Geotechnical Engineering Branch (HGEB) will determine the adequacy of the hydrologic and geotechnical engineering information cited in support of the applicant's conclusions concerning the suitability of the plant site as part of HGEB's primary review responsibilities for SRP Sections 2.4, 2.5.4, and 2.5.5. For example, as part of its primary review responsibility, the HGEB reviews the adequacy of the applicant's model describing the present and projected use of local and regional groundwater resources. Assessment of this hydrologic information by the HGEB is essential to the GB in making its. determination, for example, where appli- cable, of the subsidence potential of the site environs. An additional primary review responsibility for the HGEB consists in some cases of the verification, through investigations and testing conducted by the applicant, of the preloading history of the plant's soil foundations by means of glacial and other geologic pro- cesses. The applicant's information describing the above process is contained in SRP Section 2.5.4. The HGEB, as part of its primary review responsibility for SRP Section 2.5.4,
