An aerial radiological survey of Area 11's Plutonium Valley was conducted at the Nevada Test Site from 18 to 30 January 1982. Contour maps representing terrestrial exposure rates and soil concentrations of transuranics, /sup 235/U and /sup 137/Cs are presented on an aerial photograph. Inventories of the locale's transuranic and uranium activities are also included.

Desert algae are attractive biomass producers for capturing solar energy through photosynthesis of organic matter. They are probably capable of higher yields and efficiencies of light utilization than higher plants, and are already adapted to extremes of sunlight intensity, salinity and temperature such as are found in the desert. This report consists of an annotated bibliography of the literature on algae from the arid southwestern United States. It was prepared in anticipation of efforts to isolate desert algae and study their yields in the laboratory. These steps are necessary prior to setting up outdoor algal culture ponds. Desert areas are attractive for such applications because land, sunlight, and, to some extent, water resources are abundant there. References are sorted by state.

The Aquatic Species Program (ASP) addresses the utilization of plant biomass that naturally occurs in wetland or submerged areas. Processes are being developed through this program to make use of such aquatic species, capitalizing on their inherent capacity for rapid growth as well as their extraordinary chemical compositions.

Purpose and Scope: The purpose of this study was to evaluate the geohydrologic characteristics that influence sustained artificial recharge and to determine long-term infiltration rates in the northern part of Chino ground-water basin. Results of this study will help management to design and implement a recharge-recapture system in Chino Basin. Nine test holes were drilled, long-term infiltration tests were made, and drillers' logs and water-level data were evaluated to determine the probable effects of recharging the ground-water basin. The study was concentrated in the northern part of Chino Basin, where recharge is proposed.

This report provides an assessment of the overall effectiveness and implications of jet pumping the interstitial liquids (IL) from single-shell tanks at Hanford. The jet-pumping program, currently in progress at Hanford, involves the planned removal of IL contained in 89 of the 149 single-shell tanks and its transfer to double-shell tanks after volume reduction by evaporation. The purpose of this report is to estimate the public and worker doses associated with (1) terminating pumping immediately, (2) pumping to a 100,000-gal limit per tank, (3) pumping to a 50,000-gal limit per tank, and (4) pumping to the maximum practical liquid removal level of 30,000 gal. Assessment of the cost-effectiveness of these various levels of pumping in minimizing any undue health and safety risks to the public or worker is also presented.

The results of a program to provide an experimental data base for estimating the radiological consequences from a hypothetical sabotage attack on a light-water-reactor spent fuel shipping cask in a densely populated area are presented. The results of subscale and full-scale experiments in conjunction with an analytical modeling study are described. The experimental data were used as input to a reactor-safety consequence model to predict radiological health consequences resulting from a hypothetical sabotage attack on a spent-fuel shipping cask in the Manhattan borough of New York City. The results of these calculations are presented.

This study defines the cyclical aspects of coastal atmospheric behavior that are important to the transport and diffusion (dispersion) of radionuclides. The report is developed around discussions of the meteorological dynamics of the cyclical and (cellular) atmospheric coastal phenomena and the atmospheric transport/diffusion mechanisms along with an assessment of the measurements accompanying both. Further, the efforts directed to modeling both the atmospheric and transport/diffusion processes are summarized and evaluated. Lastly, the review is summarized through a set of conclusions about the current level of understanding of coastal atmospheric phenomena. Recommendations are offered which identify certain aspects of local scale cyclical coastal phenomena that are important to the NRC.

Recent developments of transition radiation detectors (TRD's) indicate that an efficient and practical system can be deployed for beam line particle tagging for momenta greater than 200 GeV/c. This note describes the design of a prototype system to be tested at Fermilab in Fall, 1983. Pre-prototype testing was done at BNL in March, 1983 and has been followed up by bench testing of gasses and electronics at Fermilab. The design goal is a modular system which puts few contraints on beam line configuration and hence can be adapted to any high energy secondary beam.

The GEOTHERM sample file contains 119 records for the central and eastern United States.

The geothermal resource under Lackland Air Force Base (AFB), San Antonio, Texas was studied. It is the conclusion of the investigators that a geothermal well drilled at the site recommended by this study has a high probability of delivering geothermal fluids in sufficient quantity and at adequate temperatures to support a projected space and domestic hot water heating system. An exploratory production well location is recommended in the southwest sector of the base, based upon geologic conditions and the availability of sufficient open space to support the drilling operation. It is projected that a production well drilled at the recommended location would produce geothermal fluid of 130 to 145/sup 0/F at a rate of approximately 1000 gpm with reasonable fluid drawdowns. The Environmental Assessment for the drilling portion of the project has been completed, and no irreversible or irretrievable impacts are anticipated as a result of this drilling program. The permitting process is proceeding smoothly.

Water form seven hydrothermal-geothermal, one geopressured-geothermal, and six Strategic Petroleum Reserve wells have been surveyed for twelve metals of special strategic and economic importance using trace chemical analysis techniques. The elements sought were Cr, Co, Mn, Ta, Sn, V, Nb, Li, Sr, Pt, Au, and Ag. Platinum was found at a concentration of ~50 ppb in a brine from the Salton Sea geothermal area. Brine from this region, as has been known from previous studies, is also rich in Li, Sr, and Mn. Higher concentrations (~900) of Sr are found in the high-salinity geopressured brines. None of the fluids contained interesting concentrations of the other metals. Good recovery of precious metals at sub-ppm concentrations from synthetic high salinity brines was achieved using Amborane resin, but similar recovery in the laboratory using real brines could not be demonstrated. Several analytical techniques were compared in sensitivity for the determination of the precious metals; neutron activation analysis with carrier separation is the best for gold and platinum in geothermal brines.

This assessment of the potential for production of commodity chemicals from renewable biomass resources is based on (1) a Delphi study with 50 recognized authorities to identify key technical issues relevant to production of chemicals from biomass, and (2) a systems model based on linear programming for a commodity chemicals industry using renewable resources and coal as well as gas and petroleum-derived resources. Results from both parts of the assessment indicate that, in the absence of gas and petroleum, coal undoubtedly would be a major source of chemicals first, followed by biomass. The most attractive biomass resources are wood, agricultural residues, and sugar and starch crops. A reasonable approximation to the current product slate for the petrochemical industry could be manufactured using only renewable resources for feedstocks. Approximately 2.5 quads (10/sup 15/ Btu (1.055 x 10/sup 18/ joules)) per year of oil and gas would be released. Further use of biomass fuels in the industry could release up to an additional 1.5 quads. however, such an industry would be unprofitable under current economic conditions with existing or near-commercial technology. As fossil resources become more expensive and biotechnology becomes more efficient, the economics will be more favorable. Use of the chemicals …

This report describes the results of a series of tests on the TPC superconducting magnet cryogenic system which occurred during the winter and spring of 1983. The tests occurred at interaction region 2 of the PEP colliding beam facility at the Stanford Linear Accelerator Center (SLAC). The TPC Magnet Cryogenic System which was tested includes the following major components: a remote helium compressor with a full flow liquid nitrogen purification station, 400 meters of high pressure supply and low pressure return lines; and locally a CTi Model 2800 refrigerator with two Sulzer gas bearing turbines, the TPC magnet control dewar, 70 meters of transfer lines, and the TPC thin superconducting solenoid magnet. In addition, there is a conditioner (liquid nitrogen heat exchangers and gas heaters) system for cooldown and warmup of the magnet. This report describes the local cryogenic system and describes the various steps in the cooldown and operation of the TPC magnet. The tests were successful in that they showed that the TPC magnet could be cooled down in 24 hours and the magnet could be operated on the refrigerator or a helium pump with adequate cooling margin. The tests identified problems with the cryogenic system and the …

Lower hybrid current-drive experiments have been carried out on the PLT Tokamak. Steady currents up to 175 kA have been maintained for three seconds and 400 kA for 0.3 sec by the rf power alone. The principal current carrier appears to be a high energy (approx. 100 keV) electron tail, concentrated in the central 20 to 40 cm diameter core of the 80-cm PLT discharge. Effective current drive is observed only for anti n/sub e/ less than or equal to 8 x 10/sup 12/ cm/sup -3/. This limitation may be a wave propagation phenomenon and not a fundamental plasma physics effects.

This report deals with the design principles involved in the design of a laminar-flow electrostatic-quadrupole-focused acceleration column. In particular, attention will be paid to making the parameters suitable for incorporation into a DC MEQALAC design.

The long term survivability and usefulness of the melter surface viewing borescopes would be greatly increased if a method of remote lense cleaning was available. The two units to be installed on the DWPF melter will incorporate air cooling and lense purging into their design. At present a single air supply line would serve both needs. Separating the two air services will allow the introduction of water or steam into the purge service. Tests on the prototype borescope at ETF have shown this to be an extremely effective way of cleaning the lense of occasional deposits or splatter. It is recommended that this change be incorporated into the DWPF design.

During this period we modified the characteristics of a completed cell by laser treatment in order to alter the sensitivity of the heterojunction behavior to the aging effects of oxygen and moisture. Previously we associated the changes in opposing current which affect the open-circuit voltage of the cells during aging with an increased value of the electric field in the space charge region. The present work demonstrates a strong correlation between the short-circuit current behavior and the density of deep donor states which control open-circuit voltage behavior. Practically speaking, the general degradation trends in the short-circuit current and the opposing current behavior, which we observed in control cells earlier, occur after substantial delay in the laser-treated cell. The laser treatment reduced the rate of the degradation effects in question by at least one order of magnitude. Furthermore, during the early stages of aging in wet oxygen, the laser-treated cell performance was enhanced in terms of both short-circuit current and opposing current.
