The Role of the U.S. Nuclear Waste Technical Review Board
The Nuclear Waste Technical Review Board is a new independent governmental establishment with in the Executive Branch created in December 1987 when Congress enacted the Nuclear Waste Policy...
Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...
Large Space Systems in Global Change Mitigation
Alternative courses of action are an important aspect of reacting to climate changes, including the greenhouse effect, and other environmental issues such as depletion of the ozone layer....
A Mission to Earth: Global Rural Electrification
No nation can long remain morally strong or economically competitive without an inner purpose. There are many noble projects but few which will both kindle the individual's...
Preliminary Assessment of the Power Requirements of a Manned Rover for Mars Missions
This paper presents the results of a preliminary study to determine the total mass and power requirements of a Manned Mars Rover. The primary power for the Rover is provided by a Nuclear...
Lunar Base Power Requirements, Options & Growth
A preliminary study of lunar base scenarios and associated power requirements has recently been completed. Minimum power levels of 50-100 kW are required for 'science-only'...
Power for Magma Electrolysis
This paper summarizes qualitative issues of electrical power distribution for near-term lunar facilities. The issues to be discussed were developed during a conceptual study of a Lunar...
The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...
Black Holes
For many years, scientists have searched the skies for black holes; stars even more massive than white dwarves. As of yet, there have been no 100% sure sightings. Since they do not emit...
Space Power Systems?Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...
Benefits of Radioisotope Thermoelectric Generators
Since the 1960's the United States has had the capability to reach beyond the planet Earth with the aid of satellites and interplanetary space probes. As probes such as the...
The Use of Submersible ROVs for the Inspection and Repair of Water Conveyance Tunnels
At Virginia Power's Bath County Pumped Storage Station, robotic technology was pioneered through the development of a purpose-built Remotely Operated Vehicle (ROV) to gain...
Optimal Control Strategies for Water Distribution Systems
The overall operation problem becomes one of determining which pumps to run and when to run them so that electrical unit costs and electrical demand charges are minimized while at the...
A Methodology for Optimal Control of Pump Stations
Pumping water to utility customers is an expensive service which consumes large amounts of energy. Most approaches to date require simplifications and assumptions for the specific system...
Probabilistic Analysis of Maintenance Options
Maintenance usually means service disruption, repair cost and loss of production. This is especially true for structures or components which provide basic infrastructure services, such...
Financing Small Water Supply Projects in Colorado
In order to meet the water supply needs of Colorado communities and the requirements of the Safe Drinking Water Act of 1986, the Colorado Water Resources and Power Development Authority...
Expert System for Budget Preparation and Optimal Operation of an Interconnected Power Utility
Manitoba Hydro operates a complex system of 13 reservoirs, 2 thermal and 13 hydro generating stations, and 9 interconnections to other neighbouring power utilities. The Energy Management...
Optimal Real-Time Operation of Te-Chi Reservoir
An optimization model for the 10-day operation of Te-Chi Reservoir in central Taiwan is developed. The inflow to the reservoir is forecasted by an ARX model with a Kalman Filter updating...
Estimating the Energy Rate Function for Hydro Power Production Optimization
Operations planning at Manitoba Hydro is aided by using the Energy Management and Maintenance Analysis (EMMA) computer program. EMMA is a Linear Programming (LP) based model with the objective...
Managing Two Lakes with Significant Tailwater Fisheries
Norfork and Bull Shoals Dams on the White River in Arkansas were constructed in 1944 and 1951, respectively. The authorized purposes were for flood control, hydropower generation, and...
