PNNL CRADA No. 488, Amendment 2 with Natel Energy, Inc.: The Center Sender - CRADA 488 (Final Report)
Abstract
Under the Cooperative Research and Development Agreement (CRADA) No. 488, awarded to Natel Energy, Inc. (Natel) for third place in the Fish Protection Prize 2020 initiative, research was conducted on the Center Sender concept, a simple physical or combined physical and electrical device intended to guide fish to the safest path through a hydropower intake or water diversion. Applying this to a hydropower turbine, the Center Sender can be designed to divert fish to the center of the turbine, where blade velocities are slower and the risk of severe injuries due blade strike, pinching, and grinding are reduced.Published: March 7, 2023
