The Marine Review Committee San Onofre Nuclear Generating Station: A Case Study of the Use of Scientific Data in the Regulatory Decision-Making Process
In 1974, the California Coastal Zone Conservation Commission established the Marine Review Committee (MRC) as a condition of the coastal permit for construction of the San Onofre Nuclear...

Field Experiment of a Wave Power Extracting Caisson Breakwater
The Ministry of Transport of Japan (MOT) is currently developing a fixed-OWC wave power converter called a wave power extracting caisson. This device can be used as caissons for composite-type...

Environmental Impact of a Power Plant: A Case From a Coastal Area in Venezuela
These are the results of a eight years study in which the ecological effects of Planta Centro power plant were assessed. Many aspects were included in this study, but we concentrate here...

Studies of Zooplankton Near the Nuclear Power Plant?Angra I. Preoperational Conditions (Rio de Janeiro, Brasil)
The plankton from marine bays on the coast of Rio de Janeiro State has been poorly studies, and little information is available about Ilha Grande and Sepetiba Bays and Guanabara Bay. This...

Reuse of an Industrial Wastewater at Saturn
The cooling tower at General Motor's Saturn Plant in Spring Hill, Tennessee will produce blowdown wastewater at rates as high as 500,000 gallons (1893 m³/day)....

Environmental Impacts of Drought in the Tennessee Valley
Beginning in June 1984, the Tennessee Valley region entered the most severe, extended period of drought since record keeping began in 1890. The historical annual average rainfall across...

Ground Water Treatment System Using UV/H2O2 at Sacramento Army Depot
Ground water beneath the Sacramento Army Depot (SAAD) is being extracted and treated as part of a ground water remediation program. The extraction system is achieving contaminant capture...

Pumped Storage Promise
With many utilities facing potential shortfalls in generating capacity, pumped storage hydro plants could be a key to meeting peak-period energy demand in the 1990s. Pumped storage plants...

Hydroproject Risk Analysis
Traditionally, feasibility studies performed for potential hydropower sites have included either no uncertainty or at best an ad hoc value associated with estimated benefits. However,...

Monte Carlo Simulation Techniques for Predicting Annual Power Production
The problem of the creation of a simulation model utilizing the Monte Carlo method at a single site is addressed. The result of the analysis is a picture of the production at the site...

Probabilistic Analysis of Modernization Options
Benefit-cost analysis is a standard procedure for reaching planning decisions. Cost overruns and benefit shortfalls are also common occurrences. One reason for the difficulty of predicting...

The Impact of Drought on Hydropower Generation-Case Study of Bureau of Reclamation Hydropower Plant
The paper explores the effects of extended drought on power generation at Shasta hydropower plant, a Bureau of Reclamation facility in Northern California. Statistical measures of water...

Economic Evaluation of Minimum Flow at Rockton
The Rockton Hydroelectric Project is a two-unit, 1,100 kW plant operated by South Beloit Water, Gas & Electric Company, a wholly owned subsidiary of Wisconsin Power & Light...

Renovation and Uprating of Seven Hydropower Plants in Java
The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase...

A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....

Evaluating the Dynamic Operating Benefits of Hydro Power Plants
In 1986, the Electric Power Research Institute asked Decision Focus to develop a new planning model to quantify the dynamic operating benefits of power technologies that offer operating...

Improving the Assessment of Instream Flow Needs for Fish Populations
Instream flow requirements are one of the most frequent and most costly environmental issues that must be addressed in developing hydroelectric projects. Existing assessment methods for...

Evaluating Hydro Relicensing Alternatives?Impacts on Power and Non-Power Values
The relicensing of 300 hydroelectric plants in the next decade involves a total capacity of about 4,000 MW - a $10 billion value. A methodology recently developed by Decision Focus Incorporated...

Evaluation of an Eicher Fish Diversion Screen at Elwha Dam
In the spring of 1990, the Electric Power Research Institute (EPRI) initiated testing of an inclined fish screen installed in a 9-foot diameter penstock at the Elwha Hydroelectric Project...

A Demonstration of Strobe Lights to Repel Fish
An EPRI review (EPRI, 1986) of fish protection systems for hydroelectric facilities identified strobe lights as a potential behavioral system to minimize fish entrainment. In 1988, EPRI...
