Dissolution Of Kansas Evaporites, The Radioactive Waste Disposal Problem, Barbara J. Smith

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The radioactive waste repository at Lyons, Kansas, focused attention on the problem of evaporite dissolution. More study is needed in the determination of the mechanisms responsible for deterioration. Also recent water use policies have been questioned with the need pointed out for increased effectiveness in planning. Good water planning has to take into account the role of evaporite dissolution in water quality.

The Energy Needs Of The Developing Countries, Vaman Rao

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The energy needs of the developing countries are enormous. They will grow with the passage of time as the pace of economic development accelerates and those countries enter the industrial epoch. The sheer physical non-availability of coal and petroleum to most of them makes it obligatory to choose an unconventional resource as an energy-base. The nuclear fission is the only option now available which is feasible, less-expensive and plentiful. Solar and fusion may be the ultimate sources in the steady state, when appropriate technologies are developed.

A Strategy For Utilizing Nuclear Power, Edward J. Martens

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

One of our national goals is to achieve independence in the area of energy supplies in the next few years. We believe that attaining this goal will require extensive utilization of nuclear power in conventional fission reactors. We propose that the best way to develop our nuclear resource is through government ownership of the reactors. We argue that this will minimize the risks associated with the nuclear power option and clear the way for its exploitation.

Comparison Of Nuclear And Coal Power Plants Using Net Energy Analysis, Nicholas Tsoulfanidis, Gazendra Suwal

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Net Energy Analysis has been used to compare coal and nuclear power plants. Net Energy Analysis is a method by which a system is studied in terms of the energy needed to construct and operate every unit or item associated with that system, its effects to the environment and the energy produced by the system. The results of the comparison are expressed as the ratio of the total energy output divided by the total energy input.

Attitudes Towards Quality In The Design And Construction Of Nuclear Power Plants, Daniel L. Babcock, Larry G. Harmon

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Adequate regulation of construction (and operation) of nuclear power plants has become a matter of growing national concern. Published statements by individuals speaking from two viewpoints, those of the regulatory agencies and the nuclear power industry, suggest divergent attitudes. Nineteen statements from these two points of view were evaluated for agreement or disagreement by 38 knowledgeable persons from both industry and government (of 50 solicited in a mail survey). Survey results showed a general appreciation of the need for some level of regulation and also for the possibility of over-regulation. Differences existed within as well as between the two groups, …

Vacuum-Freezing Vapor-Desublimation High Pressure Ice-Melting Process For Water Desalination, Ting-Chuan Chung

Nuclear Engineering ETDs

Y. Cheng and W. Cheng. In the study, the processing steps are divided up into several key unit operations. Some of these key unit operations are similar to some operations in existing vacuum freezing processes and have already been studied extensively. Some key operations are, however, unique to the process under study. The feasibility study is made by borrowing information for the unit operations that have already been studied in connection …

Effective Equation Of State Measurements On Uranium Dioxide, Kenneth Orvis Reil

Nuclear Engineering ETDs

The safety analysis of Liquid Metal Fast Breeder Reactor (LMFBR) systems requires knowledge of the vapor pressure of reactor fuels up to 6000 K. A new technique was developed to obtain experimental vapor pressure data for reactor fuel materials at high temperatures and pressures. Fuel samples are pulse fission heated in the Annular Core Pulse Reactor (ACPR) at heating rates comparable to those anticipated during a severe LMFBR transient. The vapor of reactor fuels may contain several dissociated fuel species, volatile fission products, and/or fission gas. The evo­lution of that pressure may be time or rate dependent. For these reasons, …

Plutonium Assessment Modeling -- Government Policy, Non-Proliferation, And The Government Fence, Harold A. Kurstedt Jr., Joel A. Nachlas

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Assessment modeling for the evaluation of plutonium as an energy resource is stressed, and generic mathematical model forms are outlined. Representative necessary objective functions are developed. Constraints and assumptions are listed. An example involving present-day light water reactor technology is demonstrated. Technical, environmental, and political implications are drawn. Specific new directions for analysis are suggested. The position of the boundary of government control and responsibility -- the government exclusion fence -- is shown to be a critical, but overlooked, constraint. Existing governmental uranium stockpiles may be an unmentioned, though important, constraint.

A Fluid Control System For The University Of Missouri--Rolla Nuclear Reactor, Billy Roger Mcpherson

Masters Theses

"Solid control rods and their movement through a reactor core present problems inherent in any moving machinery. The problems of binding, wear, and noise have to be dealt with in the usage of a solid control rod system. Therefore, an alternate system that eliminates or minimizes these problems would lower maintenance costs, extend the lifetime of the control system, and produce safer operating conditions.

This thesis presents a control system that has no moving parts inside the reactor core. The system is based upon a neutron-absorbing fluid containe��d in hollow tubes in the reactor core. The fluid level is operated …

Energy Management In The Food Store, Paul Adams

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Food store refrigeration is vital to the food distribution system and consumes much of the energy used in a supermarket. The manufacturers of food store display equipment have worked long and hard to develop new ideas in supermarket energy conservation. Hussmann's studies have uncovered a number of facts invaluable to anyone concerned with energy conservation in the supermarket.

The first fact is to realize that supermarkets are different from any other retail stores. They consume more energy each year per sq. ft. of store - or per customer - or per dollar sales than other retail stores and most commercial …

Osmo - Power. Osmotic Work; Energy Production From Osmosis Of Fresh Water/Sea-Water Systems, H. H. G. Jellinek

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

It is imperative that new and ecologically acceptable energy sources are made available. Solar energy is a source which seems to be inexhaustible and free of pollution hazards. One vast source, which can be considered to be a solar energy source consists of the system fresh water/sea water. Fresh water is continually removed by the hydrological cycle where water evaporates from the ocean due to solar radiation and is eventually precipitated again in the form of fresh water feeding various rivers. Fresh water and ocean (salt) water mix when rivers flow into the oceans. The different chemical potentials are equalized …

Alternative Approaches To Energy Modeling, Alan S. Cohen, Kenneth W. Costello

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The effects of government and private sector energy policies are varied and interrelated. Before implementing research and development programs, new technologies, environmental and price regulations, import quotas, and other energy-related policies, the consequences of these programs must be identified and quantified on a regional basis. To evaluate the regional impacts of energy policies, we need to consider production costs, transportation costs, and the location of reserves, as well as the demands for energy and nonenergy goods. Developing techniques for analyzing these factors was the objective of many previous research efforts. The strengths and weaknesses of the resulting models are discussed …

Ways To Reduce Peak Electrical Demand In South Louisiana, S. J. Gold, M. D. Bakewell, G. E. Guidry, E. F. Lewis, L. J. Naquin, B. P. Whitney

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This study analyses alternatives for coping with the peak electrical demand of hot summer afternoons. Economic and Political aspects, as well as technical feasibility, are included. It is concluded that South Louisiana may indeed be able to trim peak demand to 5% below what is anticipated by 1980 , thus making one of the coal fired stations scheduled then unnecessary. However, the contingencies (Natural Gas Shortage, Another Oil Embargo) would make a coal-fired station very desirable.

The Impact Of Direct Coupling Of Solar Cell Arrays To Electric Power Networks, Adel H. Eltimsahy, Fernando L. Alvarado, Thomas W. Boyd

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper has to do with a preliminary investigation of the economic impact of solar cells when directly coupled to a conventional three-phase power network in the Toledo area.

A correlation is established between power system demand curves and solar insolation data in the Toledo area using computer simulation. The correlation studies determine how successfully solar cell/inverter systems can alleviate the power system demand during peak hours. They also show how much solar cell area will be needed to cause a significant impact on the power generating system.

Using computer simulation the initial cost of the solar cell/inverter is compared …

Choosing Alternative Energy Systems Under Conditions Of Uncertainty, Dennis Costello

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A methodology for simulating the decision process of an investor deciding between alternative energy systems is presented. The approach assumes the investor bases his decision on cost (or rate of return) and risk. Risk is treated directly in the model and not reduced to a certainty equivalent. The rate of return-risk characteristics of many system combinations allows them to be eliminated as viable choices to the investor without reference to his personal attitude toward risk.

Oil Shale R & D -- A Bureau Of Mines Program, Steve Utter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Energy is one of our basic natural resources. Oil constitutes an important part of this resource but domestic production is dropping while imports are rising. Today, oil represents about one-half of the total energy consumed in this country, and demand is expected to grow at the rate of about 2 percent per year during the next 10 years. Increased reliance on imports can be reduced by synthetic fuels produced from the oil shale deposits of the Green River Formation in Colorado, Utah, and Wyoming. These deposits are so enormous (600 billion barrels in high- grade shale alone), that any limitations …
