REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of issues related to hydrology Secondary - None I. AREAS OF REVIEW Chapter 2 of the Standard Review Plan (SRP) discusses the site characteristics that could affect the safe design and siting of the plant. The staff reviews information presented by the applicant for a construction permit (CP), operating license (OL), design certification (DC), early site permit (ESP), or combined license (COL) concerning the hydrological setting of the site as it relates to safety-related structures, systems, and components (SSC). This SRP section applies to reviews performed for each of these types of applications. The staff’s review and findings are described in the appropriate section of the safety evaluation report (SER). The hydrological setting is described in this section of the applicant’s safety analysis report (SAR). The applicant also describes in this section, the data that are used in its safety conclusions in the SAR. 2.4.1-2 Revision 3 - March 2007 The review covers the following specific areas: 1. Interface of the Plant with the Hydrosphere: The interface of the plant with the hydrosphere includes descriptions of site location, major hydrological features in site vicinity, surface and ground water-related characteristics, and the proposed water supply to the plant. The staff’s review establishes how the safety of the plant is affected by hydrology in the vicinity of the site. The descriptions in this section should include summarized quantitative information on the major hydrologic features such as record high and low flows and other hydrologic anomalies from record. 2. Hydrological Causal Mechanisms: The staff’s review addresses identification of hydrological causal mechanisms that may require special plant design bases or operating limitations with regard to floods and water supply requirements. 3. Surface and Ground Water Uses: The staff’s review identifies current and likely future
