Content:
vents is described in SRP Sections 2.4.5 (Surge or Seiche) and 2.4.6 (Tsunami). The review of low water resulting from icing events is described in SRP Section 2.4.7 (Icing). 3. Effect of Low Water on Safety-Related Water Supply: The staff reviews the effects on the intake structure and pump design bases in relation to the events described in SAR Sections 2.4.7, 2.4.8, 2.4.9, and 2.4.11 considering the range of water supply required by the plant (including minimum operating and shutdown flows, during anticipated operational occurrences and emergency conditions) compared with availability (considering the capability of the ultimate heat sink to provide adequate cooling water under conditions requiring safety-related cooling). 4. Water Use Limits: The staff reviews the use limitations imposed or under discussion by Federal, State, or local agencies authorizing the use of the water. 5. Consideration of Other Site-Related Evaluation Criteria: The potential effects of seismic and non-seismic information on the postulated worst-case low water scenario for the proposed plant site. 6. 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 review to ensure that adverse environmental conditions due to low water will not preclude the safety function of the ultimate heat sink is performed under SRP Section 9.2.5, “Ultimate Heat Sink.” 2. The staff’s review of low water events resulting from dam failures or failures of other water control structures is described in SRP Section 2.4.4, of those resulting from surges and seiches is described in SRP
