Content:
2.4.6 in that it specifies the hydrologic phenomenon (i.e., tsunami) addressed in this section for the particular site. In general 2.4.6-7 Revision 3 -March 2007 terms, it also specifies the level of conservatism that should be used to assess the severity of tsunami hazards for the purpose of determining the design bases for SSC important to safety. This is a similar standard to that applied in reviewing ESP or COL applications for hydrologic site characteristics. For applications pursuant to 10 CFR Part 50, meeting the applicable requirements of GDC 2 provides a level of assurance that the design bases of SSC important to safety will reflect appropriate consideration of the most severe hazards likely to occur as a result of tsunamis; the adequacy of these design bases will be evaluated pursuant to other SRP sections. For applications pursuant to 10 CFR Part 52, meeting the applicable requirements of 10 CFR 52.17 and 10 CFR 52.79 that correspond to GDC 2 provides a level of assurance that the most severe hazards likely to occur as a result of tsunamis have been identified; whether GDC 2 is met with respect to the adequacy of the associated design bases will be evaluated pursuant to other SRP sections. 2. Sections 100.10(c) and 100.20(c) of 10 CFR Part 100 requires that physical characteristics of a site (including seismology, meteorology, geology, and hydrology) be taken into account when determining its acceptability for a nuclear power reactor. To satisfy the hydrologic requirements of 10 CFR Part 100, the applicant’s SAR should contain a description of the hydrogeologic and seismic characteristics of the region and an analysis of the potential hazard due to tsunami. This description should be sufficient to assess the acceptability of the site and the potential for a tsunami to influence the design of plant SSC important to safety. Meeting the requirements of Section 100.10(c) provides a level of assurance that plant SSC important to safety have been designed
