High Level Radioactive Waste Management 1991
The proceedings of the second annual international conference on High Level Radioactive Waste Management, held on April 28 - May 3, 1991, Las Vegas, Nevada, provides information on the...
Breaking Down the Barriers
The structural engineering of multistory buildings is a complex and time-consuming chore, but new design and analysis tools can greatly simplify the task. The article traces the development...
CADD for Export
By using sophisticated structural design software and high-speed PCs, engineers in Pittsburgh overcame myriad problems when designing a highrise industrial tower in India. First, they...
Benefits and Applications of Modular Hydroelectric Pumped Storage
Hydroelectric pumped storage is the only proven and most efficient technology available for energy storage. It is used by utilities to provide peak and intermediate power and to optimize...
Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...
Lake Siskiyou Power Project
The Lake Siskiyou Power Project was constructed at the foot of the existing Box Canyon Dam on the Sacramento River in Northern California. Major project features included the construction...
Net and Hydroacoustic Monitoring of Fish Passage
In 1986 EPRI published a review of available fish protection technologies for use at hydroelectric facilities. One major conclusion of that study was that fish protection systems were...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
Standard Safety and Control Concept for Double Regulated Small and Medium Hydro Turbines
The paper proposes a standard control concept for double regulated small and medium hydro turbines. The concept is based on minimum protection requirements for safe and reliable quick...
Dam Safety Hydrologic and Seismic Evaluation of TVA'S Beech Dam
Beech Dam is part of the Beech River watershed resource development located in Decatur and Henderson counties in west Tennessee. The development consists of eight dams and approximately...
Measurements of Time Lag in Concrete Gravity Dam Foundations
Uplift measurements from eight large concrete gravity dams show that the time lag between an increase in headwater level and a corresponding increase in uplift pressure is insignificant....
Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...
Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
Risk Analysis Applications for Dam Safety
Dam safety modifications are intended either to reduce the likelihood of the adverse consequences of dam failure or the magnitude of adverse consequences. For instance, widening a spillway...
Examples of Risk Assessment in Dam Safety Decision Making
Three examples of risk-based dam safety evaluations performed for dam users or operators are summarized. These studies were conducted by major U.S. engineering firms and involved experienced...
The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...
Stability Analysis of Gravity Dam Foundations with Horizontal Seams
Determination of the overall factor of safety against sliding is an important aspect in concrete dam design. Limit equilibrium methods have serious limitations. A method for determining...
Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...
