Content:
redicted operational characteristics (e.g., flow rates and velocities) are consistent with system design. ` The proposed systems are consistent with good engineering practice. ` Unusual system designs are identified. (9) Verify all significant performance characteristics and, if necessary, conduct independent analyses to ensure that performance characteristics are accurately described. The following are examples of such analyses: • intake system flow rates, flow velocities, and velocity distributions • cooling tower performance (e.g., approach to wet-bulb temperature, drift rate and droplet size, noise-level contours) • cooling pond performance (e.g., capacity, mean temperature) NUREG-1555 3.4.2-8 October 1999 • spray system performance • discharge system performance (e.g., flow velocity). IV. EVALUATION FINDINGS The depth and extent of the input to the environmental impact statement (EIS) will be governed by the characteristics of the intake, discharge, and heat dissipation systems, and by the nature and magnitude of the expected impacts in the site vicinity. The following information should be included in the EIS: ` narrative description of the intake, discharge, and heat dissipation systems ` sketches of intake, discharge, and heat dissipation components ` detailed drawings of important subsystems (e.g., perforated pipe assemblies) ` tables and graphs of important performance characteristics of the intake, discharge, and heat- dissipation systems when these parameters will be used (and referenced) by the appropriate ESRP Chapter 5.0 reviewers. V. IMPLEMENTATION The method described herein will be used by the staff in evaluating conformance with the Commission’s regulations, except in those cases in which the applicant proposes an acceptable alternative for complying with specified portions of the regulations.
