Content:
(e.g., location, size, shape, drainage area), shore regions, the regional and local groundwater environments, and existing or proposed water control structures (upstream and downstream) influencing the type of flooding mechanisms which may adversely effect safety aspects of plant siting and operation. DRAFT Rev. 3 - April 1996 2.4.1-2 II. ACCEPTANCE CRITERIA Acceptance criteria for this SRP Standard Review Plan (SRP) section relate to the following 3 regulations: A. General Design Criterion 2 (GDC 2) as it relates to structures, systems, and components important to safety being designed to withstand the effects of hurricanes, floods, tsunami, and seiches. B. 10 CFR Part 100 as it relates to identifying and evaluating hydrologic features of the site. To meet the requirements of the hydrologic aspects of GDC 2 and 10 CFR Part 100, the following specific criteria are used: 1. The description and elevations of safety-related structures, facilities, and accesses thereto should be sufficiently complete to allow evaluation of the impact of flood design bases. Site topographic maps must be of good quality and of sufficient scale to allow independent analysis of pre- and post-construction drainage patterns. All external plant structures and components should be identified on site maps. Data on surface water users, location with respect to the site, type of use, and quantity of surface water used are required. The information presented in SAR Section 2.4.1.2 forms the basis for subsequent hydrologic engineering analysis with respect to applications for a CP, OL, combined license (COL), or early site permit. Therefore, completeness and clarity are of 4 paramount importance. Maps must be legible and adequate in coverage to substantiate applicable data. Inventories of surface water users must be consistent with regional hydrologic inventories reported by applicable State and Federal agencies. The description of the hydrologic characteristics of streams, lakes, and shore regions
