ection.” 2. The review of the design of seismic Category I structures to design for the effects of flooding, including that which could result from channel diversions, is performed under SRP Section 3.4.2, “Analysis Procedures.” 3. The review to ensure that adverse environmental conditions, including freezing, 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. 2.4.9-3 Revision 3 - March 2007 4. The staff is responsible for providing the site characteristics and other hydrogeologic parameters related to channel diversions at or near the site to the organization responsible for review of the SSC potentially affected by the channel diversion to ascertain whether these effects are properly considered in the mechanical or structural design basis for the plant. 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 hydrological 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 in 10 CFR 100.20(c) for applications on or after January 10, 1997. 2. 10 CFR
