Empirical Guidelines for Fitness-for-Service Assessment of Wicket Gates

摘要

The Tennessee Valley Authority operates numerous hydroelectric facilities that utilize 1940s-era wicket gates. Cascading wicket gate failures in Unit 1 of the 140.4-MW Guntersville power station, which was constructed in 1935, and concerns raised after inspections of similar gates prompted TVA engineers to pursue comprehensive evaluations of similar-vintage wicket gates.
