September 1, 1981-November 30, 1981, was the fourth consecutive quarter of superheated steam injection at the BX In Situ Oil Shale Project. During the quarter, 117,520 barrels of water as steam were injected into project injection wells at an average wellhead temperature of 715/sup 0/F and an average wellhead pressure of 1378 PSIG. During the same period, 148,516 barrels of fluid were produced from the project production wells for a produced-to-injected fluid ratio of 1.26 to 1.0. Net oil production for the quarter was 169 barrels.

From May 1978 until April 1979, 120 New Englanders volunteered for one of six committees to devise and consider energy policy recommendations for the region's twenty-five Member, six state Congressional delegation. Sponsored by the New England Congressional Caucus and Tufts University, the New England Energy Congress was funded by grants from the Economic Development Administration, US Department of Commerce and the Office of Environment, US Department of Energy. The results of the work of the 120 delegates and nine staff was a 500 page report, Blueprint for Energy Action, containing over 150 policy recommendations to the Congress, Executive agencies, state legislatures and municipalities. The New England Congressional Caucus responded in June 1979 with an Energy Package, including twenty (and ultimately twenty-five) legislative bills and several letters to federal agencies, based on the recommendations of the Energy Congress. Following the release of the report in June 1979, 55 delegates continued their efforts as members of the Implementation Group of the Energy Congress. In July 1980, this group released a volume of Strategy Papers designed to assist in the implementation of Energy Congress recommendations. As a result of this work, a broad array of energy activities were initiated in New England and …

June 1, 1981-August 31, 1981 was the third consecutive quarter of superheated steam injection at the BX In Situ Oil Shale Project. Injection was continuous except for the period of July 14th to August 1st when the injection was suspended during the drilling of core hole BX-37. During the quarter, 99,760 barrels of water as superheated steam were injected into Project injection wells at an average well head temperature of 752/sup 0/F and an average wellhead pressure of 1312 PSIG. During the same period, 135,469 barrels of fluid were produced from the Project production wells for a produced to injected fluid ratio of 1.36 to 1.0. Net oil production during the quarter was 38 barrels.

The theoretical basis of the selective emitter is that, if a material emits only in the 8-13 micron interval, it will absorb only in the same interval. After a survey of several candidate materials, the silicon oxynitride system was found to have better optical properties than previously used materials as well as economic feasibility, and efforts to acquire a sample are described. Other promising materials are described: polyvinylidene fluoride (Tedlar), silicon monoxide, silicon dioxide, and silicon nitride. (LEW)

A single-pass continuous-flow leach test of PNL 76-68 glass beads (7 mm dia) was concluded after 420 days of uninterrupted operation. Variables included in the experimental matrix were flow-rate, leachant composition, and temperature. Analysis was conducted on all leachate samples for /sup 237/Np and /sup 239/Pu as well as a number of nonradioactive elements. Results indicated that flow-rate and leachant systematically affected the leach rate, but only slightly. Temperature effects were significant. Plutonium leach rate was lower at higher temperature suggesting that Pu sorption onto the beads was enhanced at the higher temperature. The range of leach rates for all analyzed elements (except Pu), at both temperatures, at all three flow rates, and with all three leachant compositions varied over only three orders of magnitude. The range of variables used in this experiment covered those expected in many proposed repository environments.

Weekly report of the Texas Crop and Livestock Reporting Service on turkey poult numbers in Texas and compared with other states. It includes compiled statistics across six consecutive weeks, from the week ending July 18 to the week ending August 15, during 1980 and 1981 for turkey eggs set and poults hatched.

The primary objective of this work was to demonstrate that copper silver selenide and TAGS could be segmented. The hot junction temperature was planned to be 725/sup 0/C with the segmentation temperature at 400/sup 0/C, both temperatures were selected to prevent excessive sublimation from the hot ends of the segments, respectively. The program was planned as a cooperative effort between General Atomic company and Teledyne Energy Systems. Accordingly, General Atomic synthesized the CuAgSe that was used to fabricate the test hardware that was ultimately delivered to General Atomic for testing. Both the CuAgSe and TAGS were hot pressed in an argon atmosphere then the segments were furnace-bonded to each other. A secondary objective was to produce CuAgSe powder by rapid solidification.

One of the end plug configurations we have investigated for use in a tandem mirror reactor is the axisymmetric cusp. We show that because of non-adiabaticity, the containment of 3.5 MeV alpha particles in this configuration is insufficient for the attainment of acceptable plasma performance.

The results of an accurate determination of the recoil spectrum from (n, ..gamma..) reactions in molybdenum are presented. The recoil spectrum has been calculated from nuclear level structure data and measured branching ratios. Angular correlations between successive gammas have been accounted for using the standard theoretical techniques of Racah algebra and the density matrix formalism.

The study was undertaken to determine the economic viability of surface mining to exploit the reserves. It is based on resource information already developed for NOSR 1 and conceptual designs of mining systems compatible with this resource. Environmental considerations as they relate to surface mining have been addressed qualitatively. The conclusions on economic viability were based primarily on mining costs projected from other industries using surface mining. An analysis of surface mining for the NOSR 1 resource was performed based on its particular overburden thickness, oil shale thickness, oil shale grade, and topography. This evaluation considered reclamation of the surface as part of its design and cost estimate. The capital costs for mining 25 GPT and 30 GPT shale and the operating costs for mining 25 GPT, 30 GPT, and 35 GPT shale are presented. The relationship between operating cost and stripping ratio, and the break-even stripping ratio (BESR) for surface mining to be competitive with room-and-pillar mining, are shown. Identification of potential environmental impacts shows that environmental control procedures for surface mining are more difficult to implement than those for underground mining. The following three areas are of prime concern: maintenance of air quality standards by disruption, movement, and …

This report describes the status of the initial TMX Upgrade diagnostics and the state of development of additional diagnostics being prepared for later TMX Upgrade experiments. The initial diagnostic instrument set has been described in the TMX Upgrade Proposal. This set is required to get TMX Upgrade operational and to evaluate its initial performance. Additional diagnostic instruments are needed to then carry out the more detailed experiments outlined by the TMX Upgrade program milestones. The relation of these new measurements to the physics program is described in The TMX Upgrade Program Plan.

The report examines the current debate in the United States over proposals for increased U.S. military sales to China. The study first examines the background of U.S.-China security ties since the Nixon Administration, and then sets forth the parameters of the current debate by noting a number of issues concerning U.S. military transfers to China on which all sides generally agree. It shows that Americans familiar with the issue tend to identify with different groups of opinion or "schools of thought" on the question of U.S. military transfers to China, and provides a detailed pro-con analysis of the issue. It concludes by noting cross pressures that are likely to greet U.S. policy makers as they grapple with this issue in the months ahead and offers an assessment of four policy options of possible use by U.S. policymakers.

In a novel application of the multiwire proportional counter we have imaged a collimated neutron beam. Although preliminary, the results are of sufficient import to be described here because of the potential wide application of the multiwire proportional counter to Laboratory problems. The counter was operated with a counting gas pressure of 20 Torr; the counting gas was pure C/sub 4/H/sub 10/. The radiator was a /sup 235/U foil. Under these conditions, the counter is (1) relatively insensitive to charged particles (other than fission fragments), (2) insensitive to ..gamma..-radiation, and (3) has an efficiency for the detection of fission fragments independent of incident neutron energy over a wide range of neutron energies.

Fiber-reinforced composite materials are being widely used in engineered structures. This report examines how the general form of the Weibull Criterion, including the evaluation of the parameters and the scaling of the parameter values, can be used for the prediction of component failure.

The main results are in the following 3 areas: (1) static and dynamic properties of the hydrogen diffusion model; (2) exact asymptotic solutions of the model; (3) new physics of the lattice hydrogen. The progress made during this period has been particularly significant. The hydrogen diffusion model has brought to light a number of puzzling features of hydrogen metal systems. These advances have made it possible now to begin to study some of the long-range objectives put forth in the initial proposal.

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.

The Lawrence Livermore National Laboratory (LLNL) has the necessary equipment and trained personnel to respond to a large number of hazardous material spills and fires or other emergencies resulting from these spills including injured personnel. This response capability is further expanded by the agreements that LLNL has with a number of outside response agencies. The Hazards Control Department at LLNL functions as the central point for coordinating the response of the equipment and personnel. Emergencies involving hazardous waste are also coordinated through the Hazards Control Department, but the equipment and personnel in the Toxic Waste Control Group would be activated for large volume waste pumpouts. Descriptions of response equipment, hazardous waste locations communication systems, and procedures for personnel involved in the emergency are provided.

The principles of tandem mirror operation with thermal barriers will be demonstrated in the upgrade of the Tandem Mirror Experiment (TMX-U) in 1981 and the tandem configuration of the Mirror Fusion Test Facility (MFTF-B) in 1984. Continued analysis and conceptual design over this period will evolve the optimal configuration and parameters for a power-producing reactor. In this article we describe the progress we have made in this reactor design study effort during 1980.

Progress has been ahead of planned expectations in three instances: (a) achievement of 4 mA/cm/sup 2/, short circuit current density in a MIS structure solar cell under AM1 illumination; (b) fabrication of large area (4 cm/sup 2/) MIS cells with external J/sub sc/ > 3 mA/cm/sup 2/; and (c) deposition of p/sup +/ layers by B/sub 2/H/sub 6/ gas phase doping. A program status table is included. Reproducible n layers are now routinely deposited by sputtering in Ar, H/sub 2/, and PH/sub 3/ gases. The major remaining obstacle to the goal of a 3.5% cell is the deposition of a quality i-layer. Although information deduced from infrared absorption and Raman data indicates that most of the hydrogen is bonded in the SiH configuration, the photoconductivity of the intrinsic material requires marked improvement. Two forms of magnetron sputtering, planar and cylindrical, are being exploited. The planar deposition system has the advantage that experimental costs are low; the cylindrical system is easily scalable to large product throughput. Schematic illustrations of the two systems and descriptions of apparatus modifications incorporated are included.

The requirements for the design and test of terrestrial solar cell modules for one phase of DOE's Low-Cost Solar Array Project are presented. Intermediate-load modules designed to meet this specification will generally have the following design features and characteristics: (1) nominal operating voltage (V/sub no/) between 5 Vdc and 20 Vdc; (2) ability to be series-connected to worst-case open-circuit voltages of 1000 Vdc; (3) dimensions not exceeding 1.22 m x 2.44 m (4 ft x 8 ft); (4) flat-plate configuration (non-concentrating); and (5) output power referenced to nominal operating conditions and V/sub no/. In addition to module design and performance requirements, a series of characterization and qualification tests are also specified.

A water source heat pump has been designed that is capable of operating over the range from 40 to 110/sup 0/F entering water temperature and has a heating coefficient of performance greater than six in the upper portion of this range. A computerized heat pump balance program was written to allow the performance of either a water-to-water or a water-to-air heat pump to be predicted in either the heating or cooling mode. A detailed program description, flow charts, and sample outputs are appended. The balance program was used to specify components for a high efficiency water-to-water and a high efficiency water-to-air heat pump. Performance predictions for both units in heating and in cooling are included. The water-to-water and water-to-air performance predictions were compared. The water-to-air approach was clearly superior. A detailed design and layout was done for the three solar-assisted water-to-air heat pump. A horizontal configuration was chosen for marketability reasons. The design was made consistent with high quantity production equipment available in our factories and should result in the lowest possible manufacturing cost. A key question to be answered in this project is whether a reciprocating compressor can operate without damage at the high suction pressures characteristic to the …

Tests are continuing on the shatter-resistant weathercase models and small samples. Extensive studies of composite materials has resulted in characterization of the epoxy weathercase materials mechanical properties over a wide range of temperatures and lifetime. Progress is reported on the design of the full scale prototype termination.

We have completed our evaluation of candidate longwall mines available for study in the Rocky Mountain Coal Province. This report summarizes our views and evaluation of two candidate mines, the Allen Mine in Weston, Colorado, and the Hawk's Nest Mine in Somerset, Colorado. WCC visited the Allen and the Hawk's Nest Mines, and rated them in order of preference for subsidence monitoring according to criteria given in this report. Based on these evaluations and related discussions with the Technical Project Officer, the Hawk's Nest Mine appears to be the preferred mine for subsidence monitoring, because it is the only candidate mine offering two adjacent longwall panels for monitoring wherein a full subsidence profile may be obtained for at least one of the panels. Selection of this mine requires that provisions be made for monitoring 2000 ft of overburden, whereas our proposal addressed a mine with 600 ft of overburden. Changes in instrumentation which may permit the project to remain within the current budget were investigated and are discussed.
