Content:
er below the design maximum temperature should be evaluated. The design maximum temperature and the heat load of the design basis accident, as specified in Regulatory Guide 1.27, should be provided by the organization responsible for the review of cooling water systems. Techniques for selecting the meteorological conditions for minimum heat transfer and for performing the transient analysis for cooling ponds and spray ponds are provided in NUREG-0693 and NUREG-0733, respectively. 4. Water Use Limits: In addition to natural hydrometeorologic or hydrogeologic causes of low water, the potential exists that other anthropogenic water uses could exacerbate the natural causes of low water. The potential for human-induced causes of low water in the vicinity of the site is qualitatively evaluated. The use limitations imposed or under discussion by Federal, State, or local agencies authorizing the use of the water should be reviewed. Institutional restraints on water use, such as limitations in water use and discharge permits, should be reviewed to ensure the plant will have an adequate supply and not exceed limitations imposed upon operation. If a conflict is foreseen, the applicant should be asked either to obtain a variance or make a design change to accommodate the limitation. 5. Consideration of Other Site-Related Evaluation Criteria: 10 CFR Part 100 describes site-related proximity, seismic, and non-seismic evaluation criteria for power reactor applications. Subpart A to 10 CFR Part 100 addresses the requirements for applications before January 10, 1997, and Subpart B is for applications on or after January 10, 1997. The staff’s review should include evaluation of pertinent information to determine if these criteria are appropriately used in postulation of worst-case low flow scenarios at the proposed plant site. 2.4.11-12 Revision 3 - March 2007 6.
