The Effect Of Aec/Nrc Regulation On The Development Of Nuclear Steam Power, David L. Bodde

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

Changing regulatory requirements were an important influence on the technological development of the Nuclear Steam Supply System. Manufacturers felt this influence primarily through increased requirements for information processing rather than through technical changes in the hardware. Regulatory change was driven by: the rapid growth of nuclear plant size; delays in critical safety research; public uncertainty regarding how safe nuclear plants should be; the extreme consequences of a nuclear accident; and strong pressure for the rapid commercialization of nuclear power.

Geophysical Approaches To Coal Exploration, Gerald B. Rupert

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

The exploration for minerals by geophysical means has been confined largely to the search for hydrocarbons and metallics while applications to coal exploration are somewhat limited. However, the surface reflection seismic technique has been successfully applied not only to delineating coal deposits but also as a tool in mine exploitation. Furthermore, channel waves generated underground have demonstrated potential in detecting the presence of faults in advance of the coal face and Vibroisis* experiments have been conducted whereby abandoned underground workings have been detected by surface seismic arrays. Examples of all of the preceeding are presented and discussed.

Toward Establishing A National Energy Policy, J. L. Gaddy

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

Coal must become the predominant energy source for this nation for the next 50- 100 years and petroleum must be conserved for petrochemicals. Coal gasification and liquefaction are wasteful processes that will lead tounnecessarily rapid depletion of coal reserves. Generation of electricity with coal is a more economical means of using coal for energy and this technology is already available. This paper discusses the advantages of a coal-electric energy economy and how such an economy.can be implemented.

Economic Analysis Of Wind Generation And Energy Storage For Electric Utility Systems, B. W. Jones, P. M. Moretti

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

If wind generators are being evaluated as part of a larger electric utility generation system, the economic analysis should consider all of their effects upon the make-up and operation of the rest of the system. The introduction of wind generators changes the characteristics of the effective load seen by the rest of the system and consequently shifts the optimal mix of base, swinging, and peaking capacity and their operation. Storage systems used in conjunction with wind generators must also be evaluated. The storage can also be evaluated by determining its effect upon load characteristics. It is shown that the storage …

Economic Aspects Of Imposed Air Standards, John H. Hoag, J. David Reed

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

Due to concern for the state of the environment, the federal government passed laws forcing industry to accomodate the wishes of environmentalists. In particular the Clean Air Standards Act imposed a measure of air pollution and dictated an upper bound on the amount of allowable air pollution in terms of this standard. This paper attempts to investigate the impact of such a law in the context of a two firm world. In the model each firm produces output and pollution so as to maximize profit. The pollution of all firms together is the variable which comes under constraint of the …

Feasibility Of Integrated Ocean Thermal Gradient-Nuclear Plants For The Production Of Electrical Power, Frank Ferrer, Donald Sasscer

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

A study was made of the feasibility of integrating an ocean thermal energy conversion (OTEC) electrical power plant with a nuclear power plant. The integration was such that the waste heat of the nuclear plant was used to augment the thermal efficiency of the OTEC plant. The study was performed for three shore line sites of Puerto Rico where deep cold water is found between 2 and 10 miles from shore.

Resource Recovery From Solid Waste: The Story Of Union Electric's Solid Waste Utilization System, David L. Klumb, Paul R. Brendel

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

This paper covers the design and development of a comprehensive resource recovery system capable of serving the solid waste disposal needs of the Greater St. Louis area comprising 11,500km² (4500 sq. mi.). This 7.2 x 10⁶ kg (8000 ton) per day operation will convert solid waste into milled fuel for cofiring with pulverized coal in utility boilers, and will recover magnetic and non-magnetic metals, all in an environmentally acceptable manner. Scheduled for operation in 1979, the system will be built and operated as a private enterprise venture of Union Colliery Company, a subsidiary of Union Electric Company.

Sample Design For Electricity Pricing Experiments: Anticipated Precision For A Time-Of-Day Pricing Experiment, Dennis J. Aigner

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

The primary goal of a pricing experiment is basically the same as that for an experiment in direct load control: To discover the effects of time-of-day pricing on the shape of the daily load curve for a particular customer or class of customers. For the pricing experiment, it is also of interest to know how those effects are related to the pricing structure itself.

In this paper, we consider two alternative models of kwh consumption for residential customers as the basis for calculating an optimal experimental design, and compare them in terms of the levels of precision of estimation (for …

Mass Transfer To Drops Moving Through Power Law Fluids In The Intermediate Reynolds Number Region, Robert M. Wellek, Türker Gürkan

Chemical and Biochemical Engineering Faculty Research & Creative Works

The mass transfer rate to fluid spheres is calculated for power law and Newtonian fluids by using the intermediate Reynolds number stream functions of Nakano and Tien (1970) and Yamaguchi et al. (1974), respectively. The Sh increases with increases in Re and Pe and decreases in n. Better results are obtained with Nakano and Tien's functions when Re > 10 and with Yamaguchi's functions when Re < 10. Copyright © 1976 American Institute of Chemical Engineers

An Examination Of The Adaptive Random Search Technique, M. W. Heuckroth, J. L. Gaddy, L. D. Gaines

Chemical and Biochemical Engineering Faculty Research & Creative Works

Random search procedures have recently been successfully applied to the optimization of a variety of chemical engineering problems, including optimization of chemical processes by flow sheet simulation. These procedures represent the independent variables as random variables described by probability distributions. The adaptive random search procedure centers the distribution for each variable about the best search point found and examines this region for a better point. Thus, this technique has the ability of continuously moving the search region toward the optimum, which is particularly advantageous in following constraints. This study examines the efficiency of the adaptive random search technique as applied …

Generalized Correlations For Molecular Weight And Concentration Dependence Of Zero-Shear Viscosity Of High Polymer Solutions., J. L. Zakin, R. Wu, H. Luh, Kenneth G. Mayhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

Results of a study are presented which show that two correlations of viscosity-concentration data are useful representations for data over wide ranges of mol. wt and up to at least moderately high concentrations for both good and fair solvents. Low mol. wt polymer solutions (below the critical entanglement mol. wt M//c) generally have higher viscosities than predicted by the correlations. One correlation is eta //s//p/c left bracket eta right bracket versus k prime left bracket eta right bracket c, where eta //s//p is specific viscosity, c is polymer concentration, left bracket eta right bracket is intrinsic viscosity, and k prime …

Process Optimization By Flow Sheet Simulation, L. D. Gaines, J. L. Gaddy

Chemical and Biochemical Engineering Faculty Research & Creative Works

Optimization of large or complex chemical processes often requires simplifying the system to reduce the mathematics to a form manageable by available algorithms or to reduce the time required to perform the computations. In many cases, such simplification alters the solution of the problem. Flow sheet simulation programs are ideally suited to the study of chemical processes, although the computational time is generally considered excessive for detailed optimization of complex systems by the usual procedures. This paper discusses the modifications needed to apply flow sheet simulation programs to the optimization of chemical processes. The advantages and disadvantages of the use …

Mass Transfer In Dispersed And Continous Phases For Creeping Flow Of Fluid Spheres Through Power Law Fluids, Türker Gürkan, Robert M. Wellek

Chemical and Biochemical Engineering Faculty Research & Creative Works

The diffusion equation was numerically solved by an implicit finite-difference method for the purpose of calculating the continuous phase Sherwood number, Sh, for mass transfer from an internally circulating Newtonian droplet traveling through a non-Newtonian power-law-type continuous phase in the creeping flow regime. The Mohan stream functions were used in the calculations in order to approximate the velocity profile inside and outside the droplet. The calculated Sh is presented as a function of the Peclet number, Pe, power-law index, n, and a viscosity ratio parameter, X. Sh increases as n decreases in the pseudoplastic region. The dependence of Sh on …
