Analysis of standards for energy-efficient motors (open access)

Analysis of standards for energy-efficient motors

This analysis does not lead to a clear conclusion regarding the effectiveness of standards for energy efficient motors if effectiveness is based on a benefit-cost ratio criteria. Two alternative assumptions were made regarding the appropriate measure of the costs to the private sector. In the first case it was assumed that private sector users have no biases and expect rates of return on investment that represent their true opportunity cost of capital. Under this assumption the benefit-cost ratio is .65, that is, for every dollar of cost incurred, the associated benefit is 65 cents. The alternative assumption is tha the private sector under values energy conservation investments. Under this assumption, the benfit-cost ratio of the standards program was 1.35. For every dollar spent, $1.35 is returned to society, because the standards force private sector users to correct their biases and therefore allocate capital more productively.

Investigation of mechanically hard, chemically inert antireflection coatings for photovoltaic solar modules. Final technical report, April 1, 1980-March 31, 1981 (open access)

Investigation of mechanically hard, chemically inert antireflection coatings for photovoltaic solar modules. Final technical report, April 1, 1980-March 31, 1981

The overall objective of this program is to determine the optical properties of i-Carbon (diamond-like) films and determine if these films can be developed into antireflecting (AR) coatings for silicon solar cells. The i-C films have been produced on glass, silicon, and KCl by radio frequency (RF) plasma decomposition of the alkane gases. Films were also produced on silicon solar cells by low-energy ion beam techniques. These coatings did not perform as well as those made from hydrocarbon gases. Significant progress has been made in understanding the deposition parameters that affect the optical properties of the films. The optical constants n and k have been determined over a large range of process parameters and source gas. The degree of hydrogen incorporation in these films has been studied by SIMS analysis. It was found that the lower optically absorbing films contain more hydrogen. This hydrogen does not, however, manifest itself in fundamental C-H absorption bands in the infrared. Very efficient single-layer quarter-wave i-C AR coatings have been produced on single-crystal and SOC Si solar cells. An increase in cell efficiency of 40% over uncoated cells has been achieved.

Self-potential modeling from primary flows (open access)

Self-potential modeling from primary flows

A new method for the calculation of self potentials (SP) based on induced current sources is presented. The induced current sources are due to divergences of the convective current which is driven, in turn, by a primary flow, either heat or fluid. Numerical modeling utilizing this method has been implemented using a two-dimensional transmission surface algorithm. When the primary flow is driven by the gradient of a potential, joint modeling of the primary flow and the resultant SP is possible with this algorithm. Examples of simple geometrical models in the presence of point sources for the primary flow are presented and discussed. Lastly, a field example of the joint modeling of temperature and SP data is illustrated with data from Red Hill Hot Spring, Utah.

Proceedings of the Workshop on Foundations of the Relativistic Theory of Atomic Structure : Held at Argonne National Laboratory, December 4-5, 1980 (open access)

Proceedings of the Workshop on Foundations of the Relativistic Theory of Atomic Structure : Held at Argonne National Laboratory, December 4-5, 1980

Although the Dirac theory of the hydrogen atom was proposed more than half a century ago, extension of the theory and its practical applications to complex atomic spectra took decades to mature. Development of quantum electrodynamics (QED) in its modern form, advances in high precision experimental techniques, and invention of high-speed computers have made atomic spectroscopy one of the most accurate branches of physics today, both in theory and experiment. In addition to a long-standing need to identify line-spectra coming from far and near parts of the universe, necessities such as to test QED further and to provide reliable data for ions in tokamak plasmas require an understanding of the theory of relativistic atomic structure beyond the framework of the original Dirac theory. Twenty articles from the proceedings of the workshop are presented. Contributed papers are grouped into theoretical and experimental subjects and presented after the papers for the second (atomic structure calculations) and third (experiment) sessions of the Workshop. Alphabetical listing of the authors is presented in Appendix 1, program of the Workshop in Appendix 2, and the list of the participants in Appendix 3.

Analysis of the obstacles to financing geothermal hydrothermal commercialization projects and the government programs designed to remove them (open access)

Analysis of the obstacles to financing geothermal hydrothermal commercialization projects and the government programs designed to remove them

The risks associated with geothermal hydrothermal commercialization are broken down into five categories: resource risk; technological risk; regulatory risk; investment parity risks; and institutional risk aversion. The impact of each risk upon geothermal financing is assessed. The federal government's programs to provide financial incentives for geothermal development are presented as follows: tax incentives; indirect financial incentives programs; direct grant/cost-sharing programs; and attempts at reducing regulatory risk through the enactment of legal and institutional reforms.

Guide for prioritizing power plant productivity improvement projects: modification and simplification of the DOE/MRI methodology

In recent years, the subject of public utility power plant productivity and reliability has received significant attention from both federal and state agencies and from within the utilities. One study was a FEA-sponsored program that had as its purpose the development of improved techniques for assessing cause of power plant unavailability. The results of this study have become widely known as the DOE/MRI methodology for calculating increased power plant equivalent availability resulting from instituting improvement projects. To further the development of the DOE/MRI methodology for assessing and quantifying the effect of improvement projects, the DOE initiated studies with two states to demonstrate the methodology in operating plants. These studies were focused on applying the methodology to specific power plants (fossil-fueled and nuclear) and on identifying any difficulties in using the method. In the course of these investigations, several problems were uncovered. Various recommendations were made for both eliminating the identified deficiencies in the methodology and for simplifying several of the calculations needed to evaluate proposed plant improvements. The information provided here describes four major modifications to the DOE/MRI methodology which eliminate previously uncovered deficiencies and simplify calculational methods.

Comparison of 50-year and 70-year internal-dose-conversion factors (open access)

Comparison of 50-year and 70-year internal-dose-conversion factors

The 50-year inhalation and ingestion dose commitments associated with an acute intake (of a radionuclide) of 3.7 x 10/sup 4/ Bq (1 ..mu..Ci) in one day were compared with the corresponding dose commitments calculated for a 70-year integration period resulting from a chronic intake of the same amount at a rate of 101 Bq/d (0.00274 ..mu..Ci/d) for one year. These values, known as dose conversion factors, estimate the dose accumulated during a given period of time following a unit of intake of a radionuclide. It was demonstrated that the acute intake of 3.7 x 10/sup 4/ Bq in one day and the chronic intake of 101 Bq/d for one year (a total intake of 3.7 x 10/sup 4/ Bq) result in essentially the same dose commitment for a relatively long integration period. Therefore, the comparison of 50-year acute dose conversion factors and 70-year chronic dose conversion factors is essentially only a measure of the additional dose accumulated in the 50 to 70 year period. It was found that for radionuclides with atomic mass less than 200 the percent difference in the 70-year and 50-year dose conversion factors was essentially zero in most cases. Differences of approximately 5 to 50% were …
