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 a 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 hydrological setting of the site as they relate 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 hydrogeological characteristics of the site are evaluated in this section of the applicant’s safety analysis report (SAR) to describe the effects groundwater on plant foundations and reliability of safety-related water supply and dewatering systems. The specific areas of review are as follows: 1. Local and Regional Groundwater Characteristics and Use: The staff reviews identification of the aquifers, types of onsite groundwater use, sources of recharge, present withdrawals and known and likely future withdrawals, flow rates, travel time, gradients, and other properties that affect movement of accidental contaminants in 1 Additional supporting information of prior DC rules may be found in DCD Tier 2 Section 14.3. 2.4.12-2 Revision 3 - March 2007 groundwater, groundwater levels beneath the site, seasonal and climatic fluctuations, monitoring and protection requirements, and man-made changes that have the potential to cause long-term changes in local groundwater regime. 2. Effects on Plant Foundations and other Safety-Related Structures, Systems, and Components: The staff reviews effects of groundwater levels and other hydrodynamic effects of groundwater on design bases of plant
