e been incorporated into the plant design; and, (3) provide information necessary to demonstrate compliance with any technically relevant portions of the Three Mile Island requirements set forth in 10 CFR 50.34(f), except paragraphs (f)(1)(xii), (f)(2)(ix), and (f)(3)(v). These cross-cutting review areas should be addressed by the reviewer for each technical subsection and relevant conclusions documented in the corresponding Safety Evaluation Report (SER) section. 1. Seismic Analysis Methods. For all seismic Category I SSCs, the applicable methods of seismic analysis (response spectra, time history and equivalent static load) are reviewed to confirm that the techniques employed are in accordance with the acceptance criteria as given in Subsection II.1 of this SRP section. If empirical methods or tests are used in lieu of analysis for any seismic Category I structure, these are evaluated to determine whether or not the assumptions are conservative, and whether the test procedure adequately models the seismic response. 2. Natural Frequencies and Response Loads. The summary of natural frequencies and response loads is reviewed to confirm the acceptance criteria in Subsection II.2 of this SRP section are met. 3. Procedures Used for Analytical Modeling. The procedures used for modeling of seismic systems are reviewed to determine whether the three-dimensional characteristics of structures are properly modeled in accordance with the acceptance criteria of
