Assessment of Developmental Needs for Advanced Intake Technologies

Abstract
Increasing fuel and construction costs of new power plants have emphasized the need to achieve cost‐effective, highly reliable circulating water intake designs that can improve power plant availability and performance while meeting environmental requirements. Additional concerns are to reduce maintenance, improve hydraulic conditions, and control fouling, siltation, and ice. The present paper discusses an Electric Power Research Institute (EPRI)‐sponsored study to assess the status of available intake technologies for fish protection and to develop a research program to evaluate and compare the operation, performance, cost, and reliability of selected fish protection systems. The initial assessment of all available behavioral barriers, physical barriers, collection and removal systems, and diversion systems identified for further study 11 of the most promising technologies. These 11 technologies were ranked as to the importance of various levels of specific design criteria and the importance among these criteria. The technologies were then matched with potential test sites. Biological and engineering test methodologies were developed, together with design schemes for behavioral barriers at each test site. As a result of the study, EPRI is testing behavioral barriers at several sites. EPRI also is collecting data from several existing intake facilities where angled screens, modified fish screens, and wedge‐wire screens are being evaluated.
