Content:
ion such as ice jams (coordinate review with that of SAR Section 2.4.7). These diversions may result from downstream ice blockages that may lead to flooding from backwater, or they can be upstream ice blockages that can divert the channel away from the intake. 4. Flooding of Site Due to Channel Diversion: The staff reviews the potential for forces on safety-related facilities or blockage of water supplies resulting from channel migration induced flooding (flooding not addressed by hydrometeorological induced flooding scenarios in other sections). 5. Human-Induced Causes of Channel Diversion: The staff reviews the potential of channel diversion from human-induced causes (i.e., land-use changes, diking, channelization, armoring or failure of structures). 6. Alternate Water Sources: The staff reviews alternate water sources and operating procedures (coordinate review with that of SAR Section 2.4.11.6). 7. Consideration of Other Site-Related Evaluation Criteria: The staff reviews the potential effects of seismic and non-seismic information on the postulated worst-case channel diversion scenario for the proposed plant site. 8. 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. The identification of safety-related structures and equipment that should be protected against the effects of flooding is performed under SRP Section 3.4.1, “Flood Protection.” 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
