ntity, and period of time in which the historical data have been accumulated. The staff has generally accepted the methodologies used to determine the severity of the phenomena reflected in these site characteristics, as documented in safety evaluation reports for previous licensing actions. Accordingly, the staff concludes that the use of these methodologies results in site characteristics containing sufficient margin for the limited accuracy, quantity, and period of time in which the data have been accumulated. In view of the above, the site characteristics previously identified are acceptable for use in establishing the design bases for SSCs important to safety, as may be proposed in a COL or CP application. Therefore, the staff concludes that the identification and consideration of the climatic site characteristics set forth above are acceptable and meet the requirements of 10 CFR 52.17(a)(1)(vi), 10 CFR 100.20(c) and 10 CFR 100.21(d). In view of the above, the staff finds the applicant’s proposed site characteristics related to hydrology for inclusion in an ESP for the applicant's site, should one be issued, acceptable. 2.4.12-12 Revision 3 - March 2007 3. Design Certification Reviews The following statement should be preceded by a list of the applicable site parameters used for the plant: The NRC staff acknowledges that the applicant has selected the site parameters referenced above for plant design inputs (a subset of which is included as Tier 1 information) and agrees that they are representative of a reasonable number of sites that have been or may be considered for a COL application. Effects of groundwater in the vicinity of the site are site-specific and will be addressed by the COL applicant. This should include the provision of information sufficient to demonstrate that the design of the plant falls within the site parameters specified by the siting review. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC
