ation and data by sequential comparison with infor- mation available from references. Based on the description of the hydrosphere (e.g., geographic location and regional hydrologic features) potential site flood mechanisms are identified. Subsequent SAR sections addressing the mech- anisms are cross-checked to assure that data and information required therein for review and substantiation are available. 2.4.1-2 Rev. 2 - July 1981 An important facet of the review procedure for this and other SRP sections in hydrologic areas is the site visit. The site visit provides the principal technical reviewer with independent confirmation of hydrologic characteristics of the site and adjacent environs. The site visit is discussed in Appendix A to this SRP section. IV. EVALUATION FINDINGS For construction permit (CP) reviews, findings will consist of a brief general description of the site with respect to the general hydrosphere as required by 10 CFR Part 100 and GDC 2, and of the offsite uses of surface water. For operating license (OL) reviews, findings will consist of the same material, updated as required for new information available since preparation of the CP findings. The hydrologic description for each plant site is unique. The review verifies that sufficient information has been provided and will support conclu- sions of the following-type, to be included in the staff's safety evaluation report: The proposed site for the ABC Nuclear Plant is located about 26 miles SSE of XYZ City on the southwest bank of the DEF River at about river mile 152. Plant grade will be at about elevation 220 feet above mean sea level (MSL). Significant hydrologically related plant features include the river intake structure, the natural draft cooling towers, mechanical draft nuclear service cooling towers (these are redundant towers and serve as the ultimate heat sink), and various groundwater wells. The staff concludes that the requirements of General Design Criterion 2 and 10 CFR Part 100,
