Content:
ceptual Models: The staff reviews alternate conceptual models of the hydrology at the site that reasonably bound hydrogeological conditions at the site inasmuch as these conditions affect transport of radioactive liquid effluent in the ground and surface water environment. The staff review examines whether the alternate conceptual models present a more realistic representation of the geometry of the hydrologic features and boundary conditions. 2. Pathways: The staff reviews the bounding set of plausible surface and subsurface pathways from potential points of accidental release to determine the critical pathways that may result in the most severe impact on existing uses and known and likely future uses of ground and surface water resources in the vicinity of the site. 3. Characteristics that Affect Transport: The staff reviews the ability of ground and surface water environment with respect to their ability to delay, disperse, dilute, or concentrate accidentally released radioactive liquid effluent during its transport. The staff review includes assessment of scenarios wherein accidental release of radioactive effluents is combined with hydrologic extreme events such as floods or low flows. 4. Consideration of Other Site-Related Evaluation Criteria: The staff review includes assessment of scenarios wherein accidental release of radioactive effluents is combined with potential effects of seismic and non-seismic events (e.g., assessing effects of hydraulic structures located upstream and downstream of the plant in the event of structural or operational failures and the ensuing sudden changes in the regime of flow). 5. Additional Information for 10 CFR Part 52 Applications: Additional information will be presented dependent on the type of application. For a COL application, the additional information is dependent on whether the application references an ESP, a DC, both, or neither. Information requirements are prescribed within the “Contents of Application”
