ntial impacts to the environment that may result from plant construction or operation. III. REVIEW PROCEDURES The reviewer’s description of intake hydrodynamics should be linked to the environmental descriptions provided by ESRPs 2.3.1, 3.3, and 3.4 to ensure that water body characteristics affecting intake hydrodynamics are described in sufficient detail to allow prediction of the flow field induced by the operation of the intake system. The reviewer’s analysis of physical impacts of intake system operation should be linked to the environmental descriptions and impact analyses of ESRPs 2.4.2, 5.3.1.2, and 5.3.2.1 to ensure that those environmental factors most likely to be affected are described in sufficient October 1999 5.3.1.1-5 NUREG-1555 detail to permit assessment of the predicted changes or impacts. The extent of the description of intake hydrodynamics and analysis of physical impacts should be governed by the magnitude of potential intake system impacts to aquatic biota. Intake-Hydrodynamic Description The reviewer should take the following steps to develop a description of the intake hydrodynamics: (1) Conduct a simple hydrodynamic analysis (e.g., calculate of the induced potential flow field by standard procedures and prepare an intake system hydrodynamic description. ` Discuss this with reviewers for ESRPs 2.4.2 and 5.3.1.2 to determine its adequacy for use in predicting intake system impacts to aquatic biota. ` When determined that the induced flow fields will result in only minor impacts on aquatic biota (or that no biota will be impacted), this portion of the analysis is complete. (2) When it is determined that the simple hydrodynamic analysis is insufficient (e.g., the analysis results in predictions of significant adverse impact; there are large populations of “important” aquatic biota in the vicinity of the intake), prepare a detailed analysis of intake hydrodynamics consisting of ` a review of any applicant supplied flow field predictions
