urges and waves. d. Combinations of less severe surges, coincident with runoff floods. 3. Seiches a. Meteorologically induced in inland lakes (e.g., Great Lakes and harbors) and at coastal harbors and embayments. b. Seismically induced in inland lakes. c. Seismically induced by tsunami (seismic sea waves) on coastal embayments. d. Combinations of less severe surges and seiches, coincident with runoff floods. 4. Tsunami a. Near field, or local, excitation. b. Far field, or distant, excitation. 5. Seismically induced dam failures (or breaches) and maximum water level at site from: a. Failure of dam (or dams) during safe shutdown earthquake (SSE) coincident with 25-year flood. b. Failure during operating basis earthquake (OBE) coincident with standard 2 project flood (SPF). c. Failure during other earthquakes, coincident with runoff, surge, or seiche floods where the coincidence is at least as likely as for 5.a and 5.b above. 2.4.2-3 DRAFT Rev. 4 - April 1996 6. Flooding caused by landslides a. Flood waves. b. Backwater effects due to stream blockage. 7. Ice loadings from water bodies For design certification reviews, the maximum flood level specified in the site parameter envelope that must be met by the plant design is reviewed.3 Review Interfaces4 The ECGB also reviews, under SRP Section 2.3.6 (proposed), the adequacy of the site parameter envelope specified in standard design certification applications.5 II. ACCEPTANCE CRITERIA Acceptance criteria for this SRP Standard Review Plan (SRP) section relate to the following 6 regulations: 1. General Design Criterion 2 (GDC 2) as it relates to structures, systems, and components important to safety being designed to withstand the effects of hurricanes, floods, tsunami, seiches. 2. 10 CFR Part 100 as it relates to identifying and evaluating hydrologic features of the site. To meet the requirements of the hydrologic aspects of GDC 2 and 10 CFR Part 100, the following specific criteria are used: For SAR Section 2.4.2.1
