hods presented in Reference 32 33 or standard texts. Generally, a demonstration that the water body cannot generate or sustain waves of the required period for resonance is satisfactory to discuss the possibility of damaging seiching. Similarly, seismically induced seiching is precluded if the natural period of oscillation of the water body is dissimilar from the period of precluded seismic excitation. 16 Coordination with the Geosciences Branch (GB) to determine the controlling seismic parameters may be required. If resonance is possible, the maximum seiche must be considered in the 17 selection of the critical flood design bases. DRAFT Rev. 3 - April 1996 2.4.5-6 The above reviews are performed only when applicable to the site or site region. Some items of review may be done on a generic basis. For an application referencing a certified standard design, the reviewer verifies that historical data related to surges and seiches are consistent with the flood levels specified in the site parameter envelope for the certified design. Requirements and procedures governing issuance of early site permits for approval of proposed sites for nuclear power facilities are specified in 10 CFR Part 52. Information required for such a permit includes a description of the site's hydrometeorological characteristics. For this type of permit, the procedures above should be followed.18 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and
