Content:
s (NRC 1976), contains guidance on the format and content of ERs, including hydrology, water use, and water-quality issues. Technical Rationale The technical rationale for evaluating the applicant’s description of plant water use is discussed in the following paragraph: A detailed and thorough description of the plant water consumption is essential for the evaluation of potential impacts to the environment that may result from plant, construction, or operation. III. REVIEW PROCEDURES ESRP 3.3.1 is intended to give a brief description of the water use in plant systems and the principal subsystems. The reviewer’s analysis should be closely linked with the reviews listed in the Review NUREG-1555 3.3.1-4 October 1999 Interfaces section of this ESRP to establish the plant water-use characteristics of concern to those reviews. Details of the principal subsystems are described in ESRPs 3.4.2, 3.5, and 3.6. Therefore, the reviewer of ESRP 3.3.1 should concentrate on the description of principal flow paths from the sources of water through each subsystem to the receiving water bodies without detailed flow patterns within each subsystem. With this in mind, the reviewer should take the following steps: ` Analyze the flow diagrams of plant water systems by performing simple mass balance computations to ascertain whether the reported flow rates (water source withdrawals, different plant water system needs, and discharge flows) are consistent for each plant operating mode. ` Consider periods of maximum water consumption, minimum water availability, and average operation by month. ` Determine if there are other station facilities with water uses not associated with operation of the proposed plant and include these uses in the analysis. IV. EVALUATION FINDINGS The following information from this ESRP should be included in the EIS: ` a description of the flow path of water from the water sources through each major plant water system (e.g., heat-dissipation system, sanitary
