EPRI continues development of fish-friendly turbine runner

摘要

EPRI is continuing development of its Alders/Concepts NREC turbiac. The next phase of research on this technology will entail producing an engineering design, fabricating a physical turbine model, and testing the model, EPRI says.rnFunding for this research conies from an award from the U.S. Department of Energy (DOE) for research and development of advanced water power projects. The DOE award requires a minimum 50 percent industry funding match.rnEPRI began development work on this new turbine in 1996. The goal was to develop a turbine that is more than 90 percent efficient and allows fish to pass with a mortality rate of 5 percent or less. The Alden/Con-cepts NREC turbine features a helix-shaped runner with only three blades.
