amis, taking into account records of past events. Such an approach will account for the practical physical limitations of natural phenomena at a proposed site that contribute to the potential severity of a given event. The second criterion is relevant to SRP Section 2.4.6 in that it specifies the hydrologic phenomenon that must be evaluated and analyzed at a particular reactor site. In this case, some maximum tsunami wave that could be consequential to defining the design basis flood would be evaluated. In general 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 SSCs 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 those SSCs important to safety will reflect appropriate consideration of the most severe hydrologic site characteristics likely to occur as a result of tsunamis; the adequacy of these design bases will be evaluated by the staff 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, “Contents of applications; technical information in final safety analysis report,” that correspond to GDC 2 provides a level of assurance 2.4.6-10 Revision 4 - September 2018 that the most severe hydrologic site characteristics 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 by the staff pursuant to other SRP sections. 2. Sections 100.10(c) and 100.20(c) of 10 CFR Part 100 require that the physical characteristics of a site (including seismology, meteorology, geology, and hydrology) be taken into account when determining its
