Agenda
Final Agenda (PDF) (892 K)
The following topics were covered:
- Existing and Innovative Cooling Water Intake Structure
Technologies for Reducing Impingement and Entrainment -- Including
but not limited to screening systems; fish diversion or avoidance
systems; intake location considerations; passive intake systems;
fish handling and return systems; aquatic filter barriers;
velocity reduction; and flow reduction using wet, dry, or
hybrid cooling systems, seasonal flow reductions, alternative
or nontraditional sources of cooling water, and variable speed
pumping. Costs, site applicability and retrofitting will also
be addressed.
- Demonstrating and Monitoring the Efficacy of Technologies
-- Including but not limited to demonstration programs,
monitoring programs, and comparison of monitoring methods
for various technologies.
