Biological and clinical dosimetry. Progress report, October 1, 1980-September 30, 1981
A second measurement of the event size distribution for 20 MeV neutrons was carried out at Ohio University to determine the reproducability of results. Again a significant difference between measurement and theoretical calculations by Caswell and Coyne was found. The measured fraction of events due to alpha particles was significantly lower than that predicted by the calculation of Casell and Coyne. Furthermore, the discrepancies with the theoretical calculations made by Caswell and Coyne were confirmed by measurements made with a differently designed T-E proportional counter. A non-isolated-sensor solid polystyrene calorimeter was constructed and tested during the past year. It has the advantages of, (1) simple construction, (2) simple operation, without vacuum or feedback for temperature control, (3) the capability of obtaining simultaneous measurements at different depths and azimuthal angle, and (4) the possibility of obtaining measurements with the calorimeter directed in any orientation.

Characterization of the dynamic roadway-powered electric-vehicle system
The measurements, data reduction, and analysis contained herein are for the most part preliminary. The instrumentation system for dynamic measurements was not completed and so the measurements taken were in the static mode and a limited amount of instruments was used. Most of these preliminary measurements were made to characterize the losses in the roadway and the pickup of the dynamic RPEV system. By analysis of power, voltage, current and impedance-bridge measurements (at 100 Hz and 1000 Hz), the equivalent series resistance (ESR) and equivalent parallel resistance (EPR) of the roadway and pickup inductances and capacitances were derived. Separation of the inductive and capacitive losses was difficult because of the large ratio of stored energy to power loss, that is, the Q of each of these system elements, and the separation was accomplished by modeling the system losses and making a least-squares fit to the model with the test data. The bridge data was used primarily for capacitance and inductance values and the ESR or EPR data were not analyzed.

Waste isolation safety assessment program. Task 4. Collection and generation of transport data theoretical and experimental evaluation of waste transport in selected rocks. Annual progress report, October 1, 1978-September 30, 1979
The objective of the program is to establish a basis for the prediction of radionuclide sorption in geologic environments. In FY 79, experimental and theoretical efforts were concentrated on a study of the sorption of cesium on the solid substrates Min-u-sil (quartz) and Belle Fourche clay (montmorillonite). Cesium sorption isotherms were obtained for the two substrates at 26/sup 0/C as a function of initial Cs concentration in solution (10/sup -3/M to 10/sup -9/M), pH (5 to 10) and supporting electrolyte concentration (0.002M, 0.01M, 0.1M, and 1M) NaCl and a simulated basalt groundwater in batch-type experiments using crushed material. Characterization of the solid phases included measurements of chemical compositions, particle sizes, surface areas, and cation-exchange capacities. In addition, potentiometric acid/base titrations of the solid phases were conducted in order to determine the acid dissociation and electrolyte exchange constants of the surfaces. Preliminary analysis of the sorption data indicate that while the clay data could be explained by simple mass-action expressions, the quartz data could not. Theoretical efforts were aimed at developing and testing an electrolyte binding electrical double-layer model to predict sorption isotherms. A computerized version of the model, MINEQL, which simultaneously considers surface and solution chemical equilibria, was brought to …

Double-exposure collector system. Technical progress report, April 1-June 30, 1979
A retrofit solar water-heating system has been installed in a three-story apartment building at Drexel University. The system employs two conventional collector banks (10 PPG collectors) mounted at the latitude angle for Philadelphia of 40 deg from the horizontal and two double-exposure collectors (DEC's) mounted vertically in mirrored enclosures. Although the DEC units are being used for year-round domestic water heating for the building, they are designed to provide maximum output in the winter and are therefore well-suited to solar space heating applications. Instrumentation for testing the two types of collectors has been operating in the apartment building for some time. Summer performance data have been obtained which indicate that, at a minimum, the DEC units will provide twice as much useful heat output per panel as conventional collectors. In addition some results for an overcast day showed that comparable relative performance could be expected on these days.

Energy transfer properties and mechanisms
The overall objective of the research carried out under this program is to determine the principles of collisional energy transfer and use them in predictive models and theories. In order to accomplish this goal, energy transfer properties must be determined and then analyzed to discern the underlying principles involved. In this laboratory, the experimental determination of energy transfer parameters is based on techniques that use physical properties to monitor the amount of energy in excited molecules. These techniques differ from chemical methods, based on unimolecular reaction studies, which are susceptible to interferences from complex chemical mechanisms and other complications. The physical methods have their own weaknesses and limitations, however, and much of our effort has been directed toward gaining a better understanding of these deficiencies. Two physical techniques have been proved to be particularly useful: time-resolved infrared fluorescence and time-dependent thermal lensing. As described later, we will shortly begin work using resonance enhanced multiphoton ionization techniques to investigate energy transfer in bulbs and half collisions'' in free jets. We also have been completing some calculational efforts to model formation of polycyclic aromatic hydrocarbons in stellar atmospheres.

The Advanced Light Source: A new 1. 5 GeV synchrotron radiation facility at the Lawrence Berkeley Laboratory
The Advanced Light Source (ALS), now under construction at the Lawrence Berkeley Laboratory, is being planned as a national user facility for the production of high-brightness and partially coherent x-ray and ultraviolet synchrotron radiation. The ALS is based on a low-emittance electron storage ring optimized for operation at 1.5 GeV with insertion devices in 11 long straight sections and up to 48 bend-magnet ports. High-brightness photon beams, from less than 10 eV to more than 1 keV, will be produced by undulators, thereby providing many research opportunities in materials and surface science, biology, atomic physics and chemistry. Wigglers and bend magnets will provide high-flux, broad-band radiation at energies to 10 keV. 6 refs., 10 figs., 2 tabs.

Grid-connected ICES preliminary feasibility analysis and evaluation. Final report. Volume I. Executive summary
A group of hospitals, clinics, research facilities, and medical education facilities, known as the HEAL Complex, was chosen as the site (in New Orleans) for the demonstration of a Grid-Connected Integrated Community Energy System (ICES). The contract work included a preliminary energy supply/demand assessment of the Demonstration Community, a preliminary feasibility analysis and conceptual design of a candidate Demonstration System, preliminary assessment of institutional factors, preparation of a detailed work management plan for subsequent phases of the demonstration program, firming-up of commitments from participating parties, and reporting thereon. This Phase I study has indicated that a central ICES plant producing steam, chilled water, and by-product electricity to serve the HEAL Complex is technically and economically feasible to the extent that Phase II, Detailed Feasibility and Preliminary Design, should be implemented.

Electric and Hybrid Vehicle System Research and Development Project: Hybrid Vehicle Potential Assessment. Volume VI. Cost analysis
The purpose of the cost analysis is to determine the economic feasibility of a variety of hybrid vehicles with respect to conventional vehicles specifically designed for the same duty cycle defined by the mission analysis. Several different hybrid configurations including parallel, parallel-flywheel, and series vehicles were evaluated. The ramifications of incorporating examples of advanced batteries, these being the advanced lead-acid, nickel-zinc, and sodium sulfur were also investigated. Vehicles were specifically designed with these batteries and for the driving cycles specified by the mission. Simulated operation on the missions yielded the energy consumption (petroleum and/or electricity) over the driving cycles. It was concluded that: in the event that gasoline prices reach $2.50 to $3.00/gal, hybrid vehicles in many applications will become economically competitive with conventional vehicles without subsidization; in some commercial applications hybrid vehicles could be economically competitive, when the gasoline price ranges from $1.20 to $1.50/gal. The cost per kWh per cycle of the advanced batteries is much more important economically than the specific energy; the series hybrid vehicles were found to be more expensive in comparison to the parallel or parallel-flywheel hybrids when designed as passenger vehicles; and hybrid vehicles designed for private use could become economically competitive and …

Characterization of the solid, airborne materials created by the interaction of UF/sub 6/ with atmospheric moisture in a contained volume
Several experiments have been performed in which UF/sub 6/ has been released into air under static conditions and contained in small release chambers (the largest was 8 cu ft) in order to characterize the solid product(s) created by reaction of the UF/sub 6/ with moisture in the air. Relative humidity of the air was varied, experiment to experiment, from < 2 to 100% and the amount of UF/sub 6/ released, experiment to experiment, varied from 5 to 230 mg. The releases were effected by rupture from internal pressure of the UF/sub 6/ containers (some were glass and some were metal) and the solids produced were collected and characterized by electron microscopy, X-ray diffraction, laser light scattering, and a cascaded impactor which used mass measurement to evaluate aerodynamic behavior. Various morphologies and several compounds, dependent upon conditions of release, were observed, i.e., particle size and degree of agglomeration were dependent upon the relative humidity of the air into which the UF/sub 6/ was released and the temperature of the UF/sub 6/ at time of release.

(Development of high spectral resolution lidar technology)
The first year of this grant has been devoted to the design and construction of an upgraded version of the University of Wisconsin High Spectral Resolution Lidar (HSRL). The new system incorporates additional data channels to measure depolarization and multiple scattering in the lidar return. Schematic diagrams describing the new configurations are attached to this report. Increases in optical efficiency and receiver aperture, coupled with improvements in the stiffness and the thermal stability of the mechanical system are expected to significantly improve the performance of the instrument. Most components of the system are nearly completed and system integration is about to begin. The HSRL is committed to participate in the NASA FIRE cirrus experiment during November and December of this year. Our progress is completing HSRL subsystems is outlined in the following paragraphs. 3 figs.

Geophysical assessment of near-field ground motion and the implications for the design of nuclear installations
This paper gives an in-depth discussion on the various methodologies currently available to predict the near-field ground motion from an earthquake. The limitations of the various methods are discussed in some detail in light of recently available data. It is shown that, (at least for California earthquakes) for an earthquake with a given magnitude a wide variation in the peak ground motion can occur. The change in the spectral content of the ground motion is given as a function of earthquake magnitude and peak ground acceleration. It is shown that the large g values associated with small earthquakes are relatively unimportant in the design provided the structures have a modest amount of ductility. Data recently obtained from the Friuli earthquake are also examined. Although not all the geophysical data are currently available, the provisional conclusion is reached that the relation between the strong ground motion from this earthquake and its source parameters is the same as for the western United States.

Configuration and layout of the tandem mirror Fusion Power Demonstrator
Studies have been performed during the past year to determine the configuration of a tandem mirror Fusion Power Demonstrator (FPD) machine capable of producing 1750 MW of fusion power. The FPD is seen as the next logical step after the Mirror Fusion Test Facility-B (MFTF-B) toward operation of a power reactor. The design of the FPD machine allows a phased construction: Phase I, a hydrogen or deuterium checkout machine; Phase 2, a DT breakeven machine; Phase 3, development of the Phase 2 machine to provide net power and act as a reactor demonstrator. These phases are essential to the development of remote handling equipment and the design of components that will ultimately be remotely handled. Phasing also permits more modes funding early in the program with some costs committed only after reaching major milestones.
