If water is obtained from a flowing water body, then the following plant parameter envelope/site parameter envelope (PPE/SPE) parameter and associated assumptions also apply: Average plant water withdrawals do not reduce discharge from the flowing water body by more than 3 percent of the 95 percent exceedance daily flow and do not prevent the maintenance of applicable instream flow requirements. The 95 percent exceedance flow accounts for existing and planned future withdrawals. Water availability is demonstrated by the ability to obtain a withdrawal permit issued by State, regional, or Tribal governing authorities. Water rights for the withdrawal amount are obtainable, if needed. If water is obtained from a non-flowing water body, then the following PPE/SPE parameter and associated value and assumptions also apply: Water availability of the Great Lakes, the Gulf of Mexico, oceans, estuaries, and intertidal zones exceeds the amount of water required by the plant. Water availability is demonstrated by the ability to obtain a withdrawal permit issued by State, regional, or Tribal governing authorities.

Best available technologies are employed in the design and operation of intake and discharge structures to minimize alterations due to scouring, sediment transport, increased turbidity, and erosion. Adherence to requirements in NPDES permits issued by the EPA or a given state. If water is obtained from a flowing water body, then the following PPE/SPE parameter and associated value also apply: The average rate of plant withdrawal does not exceed 3 percent of the 95 percent exceedance daily flow for the water body. If water is obtained from a non-flowing water body, then the following PPE/SPE parameters and associated values and assumptions also apply: Water availability of the Great Lakes, the Gulf of Mexico, oceans, estuaries, and intertidal zones exceeds the amount of water required by the plant. ( print page 80818) Surface Water Quality Degradation Due to Changes in Salinity Gradients Resulting from Withdrawals 1 SMALL Total plant water demand is less than or equal to a daily average of 6,000 gpm (0.379 m3 /s). If water is obtained from a flowing water body, then the following PPE/SPE parameter and associated assumptions also apply: Average plant water withdrawals do not reduce discharge from the flowing water body by more than 3 percent of the 95 percent exceedance daily flow and do not prevent the maintenance of applicable instream flow requirements. The 95 percent exceedance flow accounts for existing and planned future withdrawals. Water availability is demonstrated by the ability to obtain a withdrawal permit issued by State, regional, or Tribal governing authorities. Water rights for the withdrawal amount are obtainable, if needed. If withdrawals are from an estuary or intertidal zone, then changes to salinity gradients are within the normal tidal or seasonal movements that characterize the water body. If water is obtained from a non-flowing water body, then the following PPE/SPE parameter and associated values and assumptions also apply: Water availability of the Great Lakes, the Gulf of Mexico, oceans, estuaries, and intertidal zones exceeds the amount of water required by the plant. Water availability is demonstrated by the ability to obtain a withdrawal permit issued by State, regional, or Tribal governing authorities. Water rights for the withdrawal amount are obtainable, if needed. If withdrawals are from an estuary or intertidal zone, then changes to salinity gradients are within the normal tidal or seasonal movements that characterize the water body. Surface Water Quality Degradation Due to Chemical and Thermal Discharges 2 Undetermined The staff determined that a generic analysis to determine operational impacts on surface water quality due to chemical and thermal discharges was not possible because (1) some States may impose effluent constituent limitations more stringent that those required by the EPA, (2) limitations imposed on effluent constituents may vary among States, and (3) the establishment of a mixing zone may be required. Because all of these issues related to degradation of surface water quality from chemical and thermal discharges require consideration of project-specific information, a project-specific assessment should be performed in the supplemental environmental impact statement.

Fuel Cycle Operation: Uranium Recovery 1 SMALL Table S-3 as codified in 10 CFR 51.51 is expected to bound the impacts for new nuclear reactor fuels, because of uranium fuel cycle changes since WASH-1248, including: Increasing use of in situ leach uranium mining has lower environmental impacts than traditional mining and milling methods. Current light-water reactors (LWRs) are using nuclear fuel more efficiently due to higher levels of fuel burnup resulting in less demand for mining and milling activities. Less reliance on coal-fired electrical generation plants is resulting in less gaseous effluent releases from electrical generation sources supporting mining and milling activities.

( print page 80826) Decommissioning: Decommissioning 1 SMALL The environmental impacts for the following resource areas were generically addressed in NUREG-0586, Supplement 1, would be limited to operational areas, would not be detectable or destabilizing and are expected to have a negligible effect on the impacts of terminating operations and decommissioning: —Onsite Land Use. —Water Use. —Water Quality. —Air Quality. —Aquatic Ecology within the operational area. —Terrestrial Ecology within the operational area. —Radiological. —Radiological Accidents (non-spent-fuel-related). —Occupational Issues. —Socioeconomic. —Onsite Cultural and Historic Resources for plants where the disturbance of lands beyond the operational areas is not anticipated. —Aesthetics. —Noise. —Transportation. —Irretrievable Resource. The following issues were not addressed in NUREG-0586, Supplement 1, but have been determined to be Category 1 issues: —Non-radiological waste. —-Greenhouse Gases. Decommissioning 2 Undetermined The following two issues were identified in NUREG-0586, Supplement 1, as requiring a project-specific review: —Environmental justice. —Threatened and endangered species. Four conditionally project-specific issues identified in NUREG-0586, Supplement 1, will require a project-specific review if present: —Land use involving offsite areas to support decommissioning activities. —Aquatic ecology for activities beyond the licensed operational area. —Terrestrial ecology for activities beyond the licensed operational area. —Historic and cultural resources (archaeological, architectural, structural, historic) for activities within and beyond the licensed operational area with no current ( i.e., at the time of decommissioning) evaluation of resources for National Register of Historic Places (NRHP) eligibility. Additionally, the following two environmental resource areas are additional decommissioning impacts that require project-specific review: —Climate Change: the effects of climate change are location-specific and cannot, therefore, be evaluated generically (see Section 1.4.3.2.2, Category 2 Issues Applying Across Resources, of NUREG-2249, “Generic Environmental Impact Statement for Licensing of New Nuclear Reactors”). —Cumulative: must be considered on a project-specific basis where impacts would depend on regional resource characteristics, the resource specific impacts of the project, and the cumulative significance of other factors affecting the resource. (see Section 1.4.3.2.2, Category 2 Issues Applying Across Resources, of NUREG-2249, “Generic Environmental Impact Statement for Licensing of New Nuclear Reactors”). Issues Applying Across Resources Climate Change 2 Undetermined The effects of climate change are location-specific and cannot, therefore, be evaluated generically. For example, while climate change may cause many areas to receive less than average annual precipitation, other areas may see an increase in average annual precipitation. Therefore, applicants and staff would address the effects of climate change in the environmental documents for new nuclear reactor licensing. Cumulative Impacts 2 Undetermined Applications must individually consider the cumulative impacts from past, present, and reasonably foreseeable future actions known to occur at specific sites for proposed new nuclear reactors, and briefly present those considerations in supplemental NEPA documentation. The staff would explain whether these individualized evaluations of potential cumulative impacts alter any of the generic analyses and conclusions relied upon for Category 1 issues. The individualized cumulative impact analyses may also identify opportunities where staff might rely upon the generic analyses for some Category 1 issues for which certain of the PPE or SPE values and assumptions might be exceeded. Non-Resource Related Issues Purpose and Need 2 Undetermined Must be described in the environmental report associated with a given application. Need for Power 2 Undetermined Must be described in the environmental report associated with a given application. Site Alternatives 2 Undetermined Must be described in the environmental report associated with a given application. Energy Alternatives 2 Undetermined Must be described in the environmental report associated with a given application. System Design Alternatives 2 Undetermined Must be described in the environmental report associated with a given application. 1 Data supporting this table are contained in NUREG-2249, “Generic Environmental Impact Statement for Licensing of New Nuclear Reactors” (September 2024). 2 The categories are defined as follows: Category 1 issues—environmental issues for which the NRC has been able to make a generic finding of SMALL adverse environmental impacts, or beneficial impacts, provided that the applicant's proposed reactor facility and site meet or are bounded by relevant values and assumptions in the PPE and SPE that support the generic finding for that Category issue. ( print page 80827) Category 2 issues—Environmental issues for which a generic finding regarding the environmental impacts cannot be reached because the issue requires the consideration of project-specific information that can only be evaluated once the proposed site is identified. The impact significance ( i.e., SMALL, MODERATE, or LARGE) for these issues will be determined in a project-specific evaluation. N/A—Issues related to exposure to electromagnetic fields (EMFs) for which there is no national scientific agreement regarding adverse health effects. 3 A finding of SMALL impacts means that environmental effects are not detectable or are so minor that they will neither destabilize nor noticeably alter any important attribute of the resource. For the purposes of assessing radiological impacts, the Commission has concluded that those impacts that do not exceed permissible levels in the Commission's regulations are considered SMALL as the term is used in this table. For issues where probability is a key consideration ( i.e., accident consequences), probability was a factor in determining significance. 4 Because the Category 2 issues require a project-specific review, there are no associated values and assumptions of the plant parameter envelope and site parameter envelope. A brief summary explanation for the designation of the Category 2 issues is provided in lieu of values and assumptions.
