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 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). In this section of the safety analysis report (SAR), the geohydrological design basis is developed to ensure that any potential hazards to the SSC important to safety due to the effects of probable maximum tsunami are considered in the plant design. The staff’s review of the SAR covers the following specific areas: 1 The PMT is defined as that tsunami for which the impact at the site is derived from the use of best available scientific information to arrive at a set of scenarios reasonably expected to affect the nuclear power plant site taking into account (a) appropriate consideration of the most severe of the natural phenomena that have been historically reported or determine from geological and physical data for the site and surrounding area, with sufficient margin for the limited accuracy, quantity, and period of time in which the historical data have been accumulated, (b) appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena, and (c) the importance of the safety functions to be performed. 2.4.6-2 Revision 3 -March 2007 1. Historical Tsunami Data. The staff reviews historical tsunami data, including paleotsunami mappings and
