se and Operating Reactors,” and Section 13.6.3, “Physical Security—Early Site Permit and Reactor Siting Criteria,” address in part the location of transportation routes (e.g., rail, water, and roads), pipelines, airports, hazardous material facilities, and pertinent environmental features whose effects on security plans and response activities should be considered. In 10 CFR 52.17(a)(1)(xii), the NRC requires, in part, that an ESP applicant’s site safety analysis report include “an evaluation of the site against applicable sections of the Standard Review Plan (SRP) revision in effect 6 months before the docket date of the application.” 1.7 Hydrology Hydrologic site suitability criteria relate to potential flooding hazards, safety-related water supply, and radionuclide transport. 1.7.1 Flooding Potential sites should be examined for suitability with respect to flooding hazards. The number and types of flood-causing phenomena, flooding mechanisms, and flooding hazards to consider will depend on the site. The potential for site-scale flooding due to intense local precipitation applies to all sites. Riverine flooding due to rainfall or snowmelt, dam failure, river blockage, or channel diversion may affect sites near streams or rivers. Sites near lakes, reservoirs, estuaries, or oceans may be affected by storm surges, seiches, or tsunamis. Where applicable, the potential for flooding events due to the combined effects of multiple flooding mechanisms (e.g., rainfall with snowmelt, rainfall with dam failure, storm surge with wind waves and tides) should be considered.
