ffect SSC important to safety. 3. Ice Causes: To meet the requirements of GDC 2, GDC 44, 10 CFR 52.17, and 10 CFR Part 100, estimates of the most severe ice-induced channel diversion are needed. These setimates should be consistent with the estimates in the applicant’s SAR Section 2.4.7 (Ice Effects). 4. Flooding of Site Due to Channel Diversions: To meet the requirements of GDC 2, GDC 44, 10 CFR 52.17, and 10 CFR Part 100, estimates of the most severe channel diversion induced forces on SSC important to safety are needed. These estimates should be sufficient to demonstrate that SSC important to safety can withstand these forces without loss of their ability to function. A description of mitigation measures for flooding from channel diversions should be provided, and it should be demonstrated that these measures are consistent with the Commission’s regulations regarding performance of SSC important to safety. 2.4.9-5 Revision 3 - March 2007 5. Human-Induced Causes of Channel Diversion: To meet the requirements of GDC 2, GDC 44, 10 CFR 52.17, and 10 CFR Part 100, an assessment of the potential for human-induced channel diversions, in the vicinity of the site (e.g., land-use changes, diking, channelization, armoring or failure of such structures) is needed. An assessment of high and low water levels during channel diversion should be provided. 6 Alternate Water Sources: To meet the requirements of GDC 2, GDC 44, 10 CFR 52.17, and 10 CFR Part 100, assessments of alternate water sources and operating procedures are needed. These assessments should be consistent with SAR Section 2.4.11 (Low Water Considerations) and with SAR Section 2.4.14 (Technical Specifications and Emergency Operation Requirements). 7. Consideration of Other Site-Related Evaluation Criteria: To meet the requirements of GDC 1, GDC 2, 10 CFR 52.17, and 10 CFR Part 100, a description of the potential effects of site-related proximity, seismic, and non-seismic information on the postulated worst-case
