Content:
he Corps of Engineers (Ref. 15 16) are used to evaluate the adequacy of protection from flooding, including the static and dynamic effects of broken, breaking, and nonbreaking coincident waves. For an application referencing a certified standard design, the reviewer verifies that historical geohyrological data related to tsunamis 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 geohydrological characteristics. For this type of permit, the procedures above should be followed.17 For a standard design certification, an envelope of site-related hydrologic parameters is identified. These parameters should be representative of the most severe flooding or drawdown likely to occur as the result of a tsunami. The reviewer verifies that the site characteristics envelope meets the acceptance criteria given in subsection II of this SRP section.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 ITAAC.19 IV. EVALUATION FINDINGS For CP and early site permit reviews, the findings will consist of a statement summarizing 20 estimates of the maximum and minimum tsunami water levels, and static and dynamic effects of wave action.
