tant to safety. 2. Design Bases for Site Drainage A. Runoff for site drainage and drainage areas adjacent to the plant site, including the roofs of safety-related structures, produced by local intense precipitation. B. Potential effects of erosion and sedimentation. C. Modeling of physical rainfall-runoff processes to estimate the upper level of flood conditions adjacent to and on the plant site. 3. Consideration of Other Site-Related Evaluation Criteria. The potential effects of seismic and non-seismic information on the postulated design bases and how they relate to floods in streams and rivers in the vicinity of the site and the site region. 4. Additional Information for 10 CFR Part 52 Applications. Additional information will be presented dependent on the type of application. For a COL application, the additional information is dependent on whether the application references an ESP, a DC, both, or neither. Information requirements are prescribed within the “Contents of Application” sections of the applicable Subparts to 10 CFR Part 52. Review Interfaces Other SRP sections interface with this section as follows: 1. Flooding protection measures, including dynamic effects (hydrodynamic forces and impact forces from debris and projectiles), if required for SSC important to safety, are reviewed under Section 2.4.10. 2. 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 1 Additional supporting information of prior DC rules may be found in DCD Tier 2 Section 14.3. 2.4.3-3 Revision 4 - March 2007 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.
