es guidance for developing the hydrometeorological design bases. Regulatory Guide 1.102 describes acceptable flood protection to prevent the safety-related facilities from being adversely affected. 1. Safety-related Facilities Exposed to Flooding. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, identification of all SSC exposed to flooding is needed. This identification should be consistent with site characteristics identified by the staff during review of other SAR sections with respect to flood water surface elevations, hydrodynamic forces, and coincident wind-induced waves and runup. 2. Type of Flood Protection. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an evaluation of the applicant’s proposed flood protection measures is needed. This evaluation should assess the adequacy of protection provided to the SSC exposed to flooding and should be consistent with site characteristics identified in other SAR sections. 3. Emergency Procedures. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, a listing of proposed emergency procedures is needed. The estimated warning time required to implement each of these procedures should be provided. 4. Consideration of Other Site-Related Evaluation Criteria. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an assessment regarding the potential effects of site-related proximity, seismic, and non-seismic information on the postulated flooding protection is needed. The assessment should be sufficient to demonstrate that the applicant’s design bases appropriately account for these effects. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with GDC 2 requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such
