The Bath County Hydroelectric Pumped Storage Project provides 2,100 Mw of peak power to Virginia Electric & Power Co. and Allegheny Power Co. Called a bargain at $1.6 billion,...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
Energy Dissipation in Tidal Waterways
Energy dissipation in tidal waterways is estimated analytically by a harmonic method. Calibration of harmonic parameters is done through numerical simulation. Relations between tidal energy...
Encoder for Flood and Irrigation Data Transmission
This paper covers the design and use of a new dual parameter encoder for real time telemetry in the fields of flood forecasting and irrigation. Some history and background is presented...
Overview of EPRI'S Solid Waste Environmental Studies
The Electric Power Research Institute (EPRI) initiated a comprehensive research project in 1983 with the long-term goal of improving and validating methods for predicting the fate of chemicals...
Browns Ferry Nuclear Plant: Twenty Years Experience with Changing Thermal Criteria
This paper and its companion papers focus on one aspect of the environmental impact of Browns Ferry - the discharge of heated water. The paper provides a description of the site and the...
Browns Ferry Nuclear Plant Thermal Compliance Monitoring Network: Utilization of Data
An automated water temperature monitoring network was designed to measure ambient and downstream heated river temperatures at Browns Ferry Nuclear Plant (BFN) in Wheeler Reservoir. The...
Applications of a Diffuser Performance Model at Browns Ferry Nuclear Plant
An unsteady flow model and a diffuser performance formulation were combined to more accurately determine plant-induced temperature effects. This model has been applied to several aspects...
Field Evaluation of a Diffuser-Induced Mixing Model
Early physical model studies of the diffusers at Browns Ferry Nuclear Plant qualitatively document the mixing characteristics of the thermal effluent. Based on these studies, the dilution...
Simulation of Far-Field Thermal Effects from Browns Ferry Nuclear Plant
A computer model was used to evaluate the far-field effects of revised thermal discharge limitations at the Tennessee Valley Authority's Browns Ferry Nuclear Plant (BFN)....
Integrated Hydrothermodynamic Study of Browns Ferry Nuclear Plant
The results of hydrothermodynamic analyses and computer models discussed in previous papers are combined to present an integrated study supporting a request for alternative thermal limits...
Microcomputer-Based Index Testing of Hydroturbines
A computer-assisted system for performing index test on hydroturbines is described. This system allows for more rapid and accurate index testing of hydroturbines than has previously been...
Experimental Study of the Cross-Flow-Turbine
The performance of the Cross-Flow or Banki Turbine (C-F-T) was studied experimentally by varying the number of blades, the runner diameter, and the nozzle entry arc under flow/head variations....
Microcomputer Control for a Small Hydroelectric Peaking Plant
Peaking plants pose a special problem for control. The new facilities are generally a very small part of a large system. Determination of the parameters necessary to run the plant to best...
Economics of Hydrothermal Power Development
The overall performance of a hydrothermal power plant with pumped storage is more cost effective than its competitive counterparts such as oil and gas turbine-generators. The operation...
Seasonal Hydrothermal Operating Plans
An interactive computer model is presented which provides graphical displays of alternative generation patterns for an integrated hydroelectric and thermal system. The method for analyzing...
Portland's New Water Pumping and Hydropower Station
The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharge. A simple analytical procedure is presented for estimating the loss in turbine efficiency...
