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 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 hydrometeorological design basis is developed in this section of the applicant’s safety analysis report (SAR) to ensure that safety-related facilities and water supply are not affected by ice-induced hazards. Staff is responsible to provide site characteristics and other hydrometeorological parameters related to ice formation at or near the site to the organization responsible for review of the SSC to ascertain whether ice effects on potentially affected SSC are properly considered in the mechanical or structural design basis for the plant. 1 Additional supporting information of prior DC rules may be found in DCD Tier 2 Section 14.3. 2.4.7-2 Revision 3 - March 2007 The review covers the following specific areas: 1. Historical Ice Accumulation: The regional history and types of historical ice accumulations (i.e., ice jams, wind-driven ice ridges, floes, frazil ice formation, etc.). 2. High and Low Water Levels: The potential effects of ice-induced high or low flow levels on safety-related facilities and water supplies. 3. Ice Sheet Formation: The potential of a surface ice-sheet to reduce the volume of available liquid water in safety-related water reservoirs. 4. Ice-Induced Forces and
