of the design of seismic Category I structures to design for the effects of flooding is performed under SRP Section 3.4.2, “Analysis Procedures.” 3. The review to ensure that adverse environmental conditions will not preclude the safety function of the ultimate heat sink is performed under SRP Section 9.2.5, “Ultimate Heat Sink.” 1 Additional supporting information of prior DC rules may be found in DCD Tier 2 Section 14.3. 2.4.1-3 Revision 3 - March 2007 4. The data, including spatial and temporal data used by the applicant in support of its safety conclusions in the SAR, are reviewed in this SRP section. However, specific use of these data items in the staff’s review may be addressed in later SER sections and described in the corresponding SRP sections. 5. For DC applications and COL applications referencing a DC rule or DC application, review of the site parameters in the Design Control Document (DCD) Tier 1 and Chapter 2 of the DCD Tier 21 submitted by the applicant is performed under SRP Section 2.0, “Site Characteristics and Site Parameters.” Review of site characteristics and site- related design parameters in ESP applications or in COL applications referencing an ESP is also performed under Section 2.0. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. 10 CFR Part 100, as it relates to identifying and evaluating hydrologic features of the site. The requirements to consider physical site characteristics in site evaluations are specified in 10 CFR 100.10(c) for applications before January 10, 1997, and 10 CFR 100.20(c) for applications on or after January 10, 1997. 2. 10 CFR Part 50, Appendix A, General Design Criterion (GDC) 2, for CP and OL applications, as it relates to consideration of the most severe of the natural phenomena that have been
