REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of issues related to hydrology Secondary - Organization responsible for the review of issues related to geoscience and geotechnical engineering 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 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). In this section of the safety analysis report (SAR), the hydrological design basis is developed to ensure that any potential hazard to the safety-related facilities due to the failure of onsite, upstream, and downstream water control structures are considered in plant design. The specific areas of review are as follows: 1. Flood Waves from Severe Breaching of an Upstream Dam: Flood waves resulting from a dam breach or failure, including those due to hydrologic failure as a result of 2.4.4-2 Revision 3 - March 2007 overtopping for any reason, routed to the site and the resulting highest water surface elevation that may result in flooding of SSC important to safety. 2. Domino-Type or Cascading Dam Failures: Successive failures of several dams in the path to the plant site caused by failure of an upstream dam due to plausible reasons, such as probable maximum flood, landslide-induced severe flood, earthquakes, or volcanic activity and the effect of highest water surface elevation at the site under the cascading failure conditions. 3. Dynamic Effects on Structures: Dynamic effects of dam
