ML18190A200 ML070160659 ML18190A201 ML070730434 Dated at Rockville, Maryland, this 25th day of September, 2018. For the Nuclear Regulatory Commission. Jennivine K. Rankin, Acting Chief, Licensing Branch 3, Division of Licensing, Siting and Environmental Analysis, Office of New Reactors. APPENDIX: Proposed Definitions amozie on DSK3GDR082PROD with NOTICES1 which does not provide issue finality as described in the applicable issue finality provisions, then the staff must address the criteria for avoiding issue finality as described in the applicable issue finality provision. D Active flood protection feature: A flood protection feature that requires the change of a component’s state in order for it to perform as intended. Examples include sump pumps, portable pumps, isolation and check valves, flood detection devices (e.g., level switches), and flood doors (e.g., watertight doors). D Associated effects: Defined to include those factors such as wind waves and run-up effects; hydrostatic loading; hydrodynamic loading, including debris and water velocities; effects caused by sediment deposition and erosion; concurrent site conditions, including adverse weather conditions; and groundwater ingress. D Cliff-edge effect: A relatively-large increase in the safety consequences due to a relatively small increase in flood severity (e.g., flood height (elevation), associated effects, or flood event duration). D Concurrent hazard: A hazard that occurs along with the occurrence of another hazard as a result of a common cause (e.g., local intense precipitation and/or riverine flood event concurrent with a storm surge event caused by the same hurricane). D Consequential flooding: For Construction Permits, Operating Licenses, and COL applications, a term used to identify conditions in which the flood severity exceeds the capability of protection features (if available), including considerations for flood level, duration and/or associated effects, such that SSCs important-to-safety may be impacted. For ESP applications, the flood severity is expected to be in reference to the site characteristic flood. Consequential flooding may occur for events that are less severe and with differing characteristics (e.g., shorter warning time) than the VerDate Sep<11>2014 19:22 Sep 27, 2018 Jkt 244001 deterministically defined probable maximum events. D Flood event duration: Defines the length of time that a flood event affects the site. Flood event duration typically begins with conditions being met for entry into a flood procedure or notification of an impending flood and end when the plant is in a safe and stable state. It typically includes site warning time (or preparation time, if available) and period of inundation and recession. D Flood hazard: Those hydrometeorologic, geoseismic, or structural failure phenomena (or combination thereof) that may produce flooding at or near nuclear power plant site. D Flood-response SSCs: SSCs that may be used to maintain key safety functions during conditions that might occur during an external flood scenario, including SSCs that are indirectly related to maintenance of key safety functions (e.g., barriers that protect SSCs from floodwaters or other related effects). D Local intense precipitation (LIP): A locally-heavy rainfall event, which is typically defined by specifying three parameters: Total rainfall depth, total rainfall duration, and spatial extent (area). LIP is typically associated with small-scale events over geographic areas on the scale of the reactor powerblock and the controlled area (typically on the order of one to ten mi2) and using an assumption that the short-term rainfall rate is aerially uniform although the rainfall rate (intensity) typically varies over the total rainfall event duration. Although the rainfall duration parameter selected as part of evaluating this flood-causing mechanism will depend on site-specific characteristics (e.g., site drainage, susceptibility to ponding of water, etc.), LIP events are typically associated with a relatively short duration (e.g., 1- to 6-hrs) of intense rainfall compared to the duration of rainfall events applied to the evaluation of basin-wide flooding involving streams and rivers. Smaller-scale intense rainfall events may be imbedded within longer rainfall events for streams and rivers and, depending on site drainage characteristics, may affect a reactor site for longer durations. In the context of the PO 00000 Frm 00091 Fmt 4703 Sfmt 4703 ML18267A055 ML18264A035 ML18183A446 ML063600394 ML18267A076 Standard Review Plan, LIP is defined generically and is not limited to stylized deterministic events, such as the so-called 1hr, 1- mi2, probable maximum precipitation (PMP) event with specified duration and temporal distribution that produces the maximum rainfall inundation at a given plant site. D Passive flood protection feature: A flood protection feature that does not require the change of state of a component in order for it to perform as intended. Examples include dikes, berms, sumps, drains, basins, yard drainage systems, walls, floors, structures, penetration seals, and barriers exterior to the immediate plant area that is under licensee control. D Powerblock elevation (for purposes of plant design and flood hazard assessment): The as-built elevation of the ground surface in the area of the site’s powerblock.
