Application of the Argonne Advanced Acceleration Test Facility to development for conventional accelerators
The Argonne Advanced Acceleration Test Facility is designed as a powerful tool to test ideas for very high gradient acceleration schemes based on direct beam excitation of plasmas, metal structures, dielectrics, etc. The characteristic size in these systems is )approximately) 1 cm, corresponding to frequencies )approximately) 10 GHz. The question addressed here is whether the special features of this facility have application as well to the development of components for the more conventional, lower frequency, accelerators now operating or under development. It is suggested that the usefulness of the facility for the development of conventional systems could be enhanced by a provision for longer time delay between driver and witness beam pulses. 9 refs., 2 figs.

HVAC (heating, ventilation, air conditioning) literature in Japan: A critical review
Japanese businessmen in the heating, ventilation, air conditioning, and refrigeration (HVACandR) industry consider the monitoring of technical and market developments in the United States to be a normal part of their business. In contrast, efforts by US businessmen to monitor Japanese HVAC and R developments are poorly developed. To begin to redress this imbalance, this report establishes the groundwork for a more effective system for use in monitoring Japanese HVAC and R literature. Discussions of a review of the principal HVAC and R publications in Japan and descriptions of the type of information contained in each of those publications are included in this report. Since the Japanese HVAC and R literature is abundant, this report also provides practical suggestions on how a researcher or research manager can limit the monitoring effort to the publications and type of information that would most likely be of greatest value.

Comparative Evaluation of DHDECMP (dihexyl-N,N-diethylcarbamoyl-methylphosphonate) and CMPO (octylphenyl-N,N,-diisobutylcarbamoylmethylphosphine oxide) as Extractants For Recovering Actinides From Nitric Acid Waste Streams
Certain neutral, bifunctional organophosphorous compounds are of special value to the nuclear industry. Dihexyl-N,N-diethylcarbomoylmethylphosphonate (DHDECMP) and octylphenyl-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO) are highly selective extractants for removing actinide and lanthanide elements from nitric acid. We obtained these two extractants from newly available commercial sources and evaluated them for recovering Am(III), Pu(IV), and U(VI) from nitric acid waste streams of plutonium processing operations. Variables included the extractant (DHSECMP or CMPO), extractant/tributylphosphate ratio, diluent, nitrate concentration, nitrate salt/nitric acid ratio, fluoride concentration, and contact time. Based on these experimental data, we selected DHDECMP as the perferred extractant for this application. 18 refs., 30 figs.

WASTES: Waste System Transportation and Economic Simulation--Version 2: Technical Reference Manual
The Waste System Transportation and Economic Simulation (WASTES) Technical Reference Manual was written to describe and document the algorithms used within the WASTES model as implemented in Version 2.23. The manual will serve as a reference for users of the WASTES system. The intended audience for this manual are knowledgeable users of WASTES who have an interest in the underlying principles and algorithms used within the WASTES model. Each algorithm is described in nonprogrammers terminology, and the source and uncertainties of the constants in use by these algorithms are described. The manual also describes the general philosophy and rules used to: 1) determine the allocation and priority of spent fuel generation sources to facility destinations, 2) calculate transportation costs, and 3) estimate the cost of at-reactor ex-pool storage. A detailed description of the implementation of many of the algorithms is also included in the WASTES Programmers Reference Manual (Shay and Buxbaum 1986a). This manual is separated into sections based on the general usage of the algorithms being discussed. 8 refs., 14 figs., 2 tabs.

Evaluation of Low-Cost Salmon Production Facility, 1987 Annual Report.
Activities of the study include investigating the potential for community involvement; evaluating natural outmigration of smolts; providing cumulative production of quality salmon; aiding in development of optimum density levels in earthen rearing ponds; and augmenting a unique ''known stock'' fishery. The coded-wire tagging program was continued to aid in the accomplishment of the objectives. Monitoring of downstream smolt migration from CEDC release sites continued. Data collected is beginning to show that smolt size and stream flow have an effect on smolt migration. Release of comparatively larger smolts and release during elevated stream flows, demonstrates a more rapid migration. Release of larger smolts also enhances adult survival. Smolts released at 9.5 fish/pound suvived by nearly ten times that of smolts released at 16.3 fish/pond and by nearly 5 1/2 times when released at about 13.5 fish/pound. In 1987 the CEDC Fisheries Project reared and released a total of approximately 1.7 million salmon smolts. Coho production was about 300,000, fall chinook at about 1.4 million, and Rogue stock fall chinook a a minimal 20,000. Preliminary overall adult survival figures for 1987 show a 0.69% for tule chinook, 2.89% for Rogue stock fall chinook, and 0.82% for coho. Chinook survival was up from …

On bunch lengthening using the fourth harmonic cavity in the NSLS VUV ring
It has been suggested that the phase of the beam excited voltage in the harmonic cavity can be controlled by detuning its resonant frequency from the beam current harmonic. Unfortunately the detuning needed to flatten the acceleration waveform also corresponds to the region of Robinson instability for the harmonic cavity. Therefore, lengthening the bunch may be followed by large amplitude synchrotron oscillation of the bunch center of mass. Bunch lengthening is discussed in this note from several points of view. There follows a simple review of single electron oscillations in a quartic potential. Then equations are developed for the coupled oscillations of a cavity and a rigid bunch as a fully nonlinear, time dependent initial value problem. Next, a computer program that solves these equations for one, two or more cavities, with and without externally driven fields, is described and some simulations of the harmonic cavity interaction are shown. Finally, the fully nonlinear equations are linearized to derive a dispersion relation for the case of beam excitation in the harmonic cavity. 6 refs., 5 figs.

SPARK Version 1. 1 user manual
This manual describes the input required to use Version 1.1 of the SPARK computer code. SPARK 1.1 is a library of FORTRAN main programs and subprograms designed to calculate eddy currents on conducting surfaces where current flow is assumed zero in the direction normal to the surface. Surfaces are modeled with triangular and/or quadrilateral elements. Lorentz forces produced by the interaction of eddy currents with background magnetic fields can be output at element nodes in a form compatible with most structural analysis codes. In addition, magnetic fields due to eddy currents can be determined at points off the surface. Version 1.1 features eddy current streamline plotting with optional hidden-surface-removal graphics and topological enhancements that allow essentially any orientable surface to be modeled. SPARK also has extensive symmetry specification options. In order to make the manual as self-contained as possible, six appendices are included that present summaries of the symmetry options, topological options, coil options and code algorithms, with input and output examples. An edition of SPARK 1.1 is available on the Cray computers at the National Magnetic Fusion Energy Computer Center at Livermore, California. Another more generic edition is operational on the VAX computers at the Princeton Plasma Physics Laboratory …

PHOTON: A user's manual
PHOTON has proven very useful in the development of the X17 superconducting wiggler beamline. Its use has determined the shielding required from the wiggler device to the very end of the beamline in the hutches and angiography section. Doses calculated by this program have been compared with experimental results from conventional bending magnet beamline with great success. In each case the program consistently overestimated the dose by factors ranging from 2 to 10. The reason for this overestimation is understood and was not refined further in the program in order to maintain some level of safety in the shielding calculations. PHOTON should prove useful in the design of any beamline. Its ability to calculate power deposited and spectra transmitted through nearly arbitrary beamline configurations as well as the scattered radiation doses through shielding walls make it a very powerful tool.

The role of market research in the commercialization of technology
The objectiv eof this report is to provide information on available empirical work that describes criteria used by the residential consumer market in selectign energy and energy-related products. This market is important to the US Department of Energy's (DOE) Office of Building and Community Services (OBCS), which sponsors the developement of many energy-conserving technologies ultimately used by the residential consumer. In this report, the consumer decision-making process is described, and case studies are presented to illustrate the importance of conducting systematic market research in the early stages of the technology-development process. Consumer decision making is examined through a discussion of the steps of the decision-making process: problem recognition, information search, evaluation of alternatives, and purchase decision. Post-purchase behavior and its implications to the OBCS and to commercial marketing research are also discussed. The four case studies that are presented in this report illustrate the importance of market research in building energy loss, lighting, water heating, and refrigeration: (1) low-emissivity (low-E) windows; (2) long life light bulbs; (3) heat pump water heaters; and (4) energy efficient refrigerator-freezer.

Water quality in the vicinity of Fenton Hill, 1985 and 1986: Progress report
Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continuing program of environmental studies. Data on chemical quality of water were determined for samples collected from 13 surface water and 19 groundwater stations in 1985 and 1986. There were slight variations in the chemical quality of the ground and surface water in 1985 and 1986 as compared with previous analyses; however, these variations are within normal seasonal fluctuations. Chemical uptake in soil, roots, and foliage is monitored in the canyon, which receives intermittent effluent release of water from tests in the geothermal circulation loop and occasional fluids from drilling operations. The chemical concentrations found in soil, roots, and vegetation as the result of effluent release have shown a decrease in concentration down-canyon and also have decreased in concentration with time since the larger releases that took place in the late 1970s and early 1980s. 18 refs., 7 figs., 9 tabs.

Mechanisms governing fine particulate emissions from coal flames
Efforts in this period focused on refining the plans for engineering analysis and fundamental experiments based on the results of a literature review, and modifying the Malvern laser diffraction particle sizer to operate at particle sizes down to 0.5 microns. The engineering analysis plan is to concentrate on development of new models and adaptation of existing models for fine particulate formation by three categories of mechanisms: particle breakup/ash coalescence; direct passage, fragmentation, or agglomeration of extraneous mineral matter; and bubble formation/breakup. The plan for fundamental experiments is to develop a fast, online, optical particle sizing technique which will span the 0.5 to 10 micron size range of interest; to perform global experiments to identify the important parameters affecting fine particle formation; and to perform mechanistic experiments to test specific hypotheses about the mechanisms which control fine particle formation in coal combustion.

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent
AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-scale, fixed-bed reactor. Durability may be defined as the ability of the sorbent to maintain important physical characteristics such As size, strength, and specific surface area during 10 cycles of sulfidation and oxidation.

Characterization of simulated low-level waste grout produced in a pilot-scale test
The objectives of a pilot-scale grout test were to determine the homogeneity of the grout produced under conditions similar to those planned for the TGF, to evaluate performance of candidate grout processing equipment for the TGF, and to evaluate properties of grout that was produced during continuous operation over an extended time period and cured in a large monolith. This report addresses the first and third objectives. Tests were conducted on pilot-scale grout slurry, simulated waste solution, dry solids blend samples, and cured grout samples. Grout slurry collected at two points during the pilot-scale test and slurry produced in the laboratory were characterized by measuring rheology, drainable liquid, and penetration resistance. Cured grout samples included samples collected during the pilot-scale test and cured in the laboratory, samples produced in the laboratory, samples obtained from tubes inserted into the monolith, and samples from cored sections of the monolith. Tests conducted on the cured samples included compressive strength, density, ultrasonic pulse velocity, leachability, and microstructural characterization. 10 refs., 12 figs., 16 tabs.
