Uranium resources and their implications for fission breeder and fusion hybrid development

Description: Present estimates of uranium resources and reserves in the US and the non-Communist world are reviewed. The resulting implications are considered for two proposed breeder technologies: the liquid metal fast breeder reactor (LMFBR) and the fusion hybrid reactor. Using both simple arguments and detailed scenarios from the published literature, conditions are explored under which the LMFBR and fusion hybrid could respectively have the most impact, considering both fuel-supply and economic factors. The conclusions emphasize strong potential advantages of the fusion hybrid, due to its inherently large breeding rate. A discussion is presented of proposed US development strategies for the fusion hybrid, which at present is far behind the LMFBR in its practical application and maturity.

Physics issues in mirror and tandem mirror systems

Description: Over the years the study of the confinement of high temperature plasma in magnetic mirror systems has presented researchers with many unusual physics problems. Many of these issues are by now understood theoretically and documented experimentally. With the advent of the tandem mirror idea, some new issues have emerged and are now under intensive study. These include: (1) the generation and control of ambipolar confining potentials and their effect on axial confinement and, (2) the combined influence of nonaxisymmetric magnetic fields (used to ensure MHD stability) and electric magnetic particle drifts on radial transport. Physics considerations associated with these two categories of issues will be reviewed, including concepts for the control of radial transport, under study or proposed.

Kinematic Stirling engine as an energy conversion subsystem for paraboloidal dish solar thermal power plants

Description: The potential of a suitably designed and economically manufactured Stirling engine as the energy conversion subsystem of a paraboloidal dish-Stirling solar thermal power module has been estimated. Results obtained by elementary cycle analyses have been shown to match quite well the performance characteristics of an advanced kinematic Stirling engine, the United Stirling P-40, as established by current prototypes of the engine and by a more sophisticated analytic model of its advanced derivative. In addition to performance, brief consideration has been given to other Stirling engine criteria such as durability, reliability, and serviceability. Production costs have not been considered here.

Summary of photovoltaic system performance models

Description: The purpose of this study is to provide a detailed overview of photovoltaics (PV) performance modeling capabilities that have been developed during recent years for analyzing PV system and component design and policy issues. A set of 10 performance models have been selected which span a representative range of capabilities from generalized first-order calculations to highly specialized electrical network simulations. A set of performance modeling topics and characteristics is defined and used to examine some of the major issues associated with photovoltaic performance modeling. Next, each of the models is described in the context of these topics and characteristics to assess its purpose, approach, and level of detail. Then each of the issues is discussed in terms of the range of model capabilities available and summarized in tabular form for quick reference. Finally, the models are grouped into categories to illustrate their purposes and perspectives.

Survey of manufacturers of high-performance heat engines adaptable to solar applications

Description: This report summarizes the results of an industry survey made during the summer of 1983. The survey was initiated in order to develop an information base on advanced engines that could be used in the solar thermal dish-electric program. Questionnaires inviting responses were sent to 39 companies known to manufacture or integrate externally heated engines. Follow-up telephone communication ensured uniformity of response.

CONC/11: a computer program for calculating the performance of dish-type solar thermal collectors and power systems

Description: CONC/11 is a computer program designed for calculating the performance of dish-type solar thermal collectors and power systems. It is intended to aid the system or collector designer in evaluating the performance to be expected with possible design alternatives. From design or test data on the characteristics of the various subsystems, CONC/11 calculates the efficiencies of the collector and the overall power system as functions of the receiver temperature for a specified insolation. If desired, CONC/11 will also determine the receiver aperture and the receiver temperature that will provide the highest efficiencies at a given insolation. The program handles both simple and compound concentrators. CONC/11 is written in Athena Extended Fortran (similar to Fortran 77) to operate primarily in an interactive mode on a Sperry 1100/81 computer. It could also be used on many small computers.

ECUT: Energy Conversion and Utilization Technologies Program. Biocatalysis Research Activity annual report, FY 1983

Description: The activities of the Biocatalysis Research Activity during FY 1983 were organized into the Biocatalysis and Molecular Modeling work elements and a supporting planning and analysis function. In the biocatalysis work element, progress was made in developing a method for stabilizing genetically engineered traits in microorganisms, refining a technique for monitoring cells that have been genetically engineered, identifying strains of fungi for highly efficient preprocessing of biomass for biocatalyzed processes, and determining molecular level conditions for optimizing the efficiency of bioreactors. In the Molecular Modeling work element, a preliminary model of the behavior of enzymes was developed. Also, a preliminary investigation of the potential for synthesizing enzymes for use in electrochemical processes was completed. As part of the Activity's supporting planning and analysis efforts, contact with industry and universities was made to define key biocatalysis technical issues and to broaden the range of potential participants in the Activity. Additionally, analyses were conducted to identify and evaluate potential concepts for future research funding by the Activity. 1 figure, 2 tables.

Performance of the Lester battery charger in electric vehicles

Description: Tests were performed on an improved battery charger manufactured by Lester Electrical of Nebraska, Inc. This charger was installed in a South Coast Technology Rabbit No. 4, which was equipped with lead-acid batteries produced by ESB Company. The primary purpose of the testing was to develop test methodologies for battery charger evaluation. To this end tests were developed to characterize the charger in terms of its charge algorithm and to assess the effects of battery initial state of charge and temperature on charger and battery efficiency. Tests showed this charger to be a considerable improvement in the state of the art for electric vehicle chargers.
