Diffusion of Slow Electrons in Gases
The properties of electrons in a gas and an external electric field, e.g., agitation velocity, free path, energy lost per collision, and collision cross sections, were determined for electrons of energy less than 2 ev in a large number of gases. The computations were made from previously measured values for Townsend's energy factor or the ratio of electron agitation energy to molecule thermal energy. Results are presented for hydrogen, nitrogen, carbon dioxide, methane, ethylene, cyclopropane, and argon. (D.L.C.)

Waste Treatment and Disposal Progress Report for June and July 1961
7 7 6 4 : 9 8 9 6 5 : 9 aluminum nitrate waste was calcined in the close-coupled continuous evaporator-pot calciner unit. Waste oxides from TBP-25 waste were incorporated into glassy materials after the addition of phosphate and borate fluxing agents. Melts formed at 850 to 950 deg C were glassy solids when cooled and had densities from 2.41 to 2.47 g/ml. Waste volurne reduction factors were from 7.6 to 9.3. Low-Level Waste Treatment. A demonstration run was completed in the 60 liters/hr scavenging-ion exchange pilot plant on ORNL low-activity waste. Decontamination factors were satisfactory after 1500 resin bed voluumes of waste had been treated, i. e, Sr> 1000, TRE 100, Cs> 100, and sufficiently high for other activities that the waste activity was reduced to <10% of MPC. The physical properties of vermiculite, clinoptilolite, and rock phosphate were found to be suitable for second-stage treatment of process waste. Engineering, Econommc, and Hazards Evaluation. A cost study of the conversion of high-level solutions to solids by pot calcimation was completed. Aging had a negligible effect on costs for processing in a given vessel size. The lowest cost was 0.87 x 10/sup-2/ mill/kwh/sub 3/ for processing acidic Purex and …

[Letter from Jack Davis to Mitch Jericho, October 24, 1995]
Photocopy of a letter from Jack Davis, Dean of the School of Visual Arts at the University of North Texas, to Mitch Jericho. In regards to Jeff Patchen speaking at the Young Audiences conference in Dallas. Davis and his NTIEVA co-director Bill McCarter have discussed bringing Patchen to the University of North Texas, however, there is no justifiable reason to bring him to the School of Visual Arts since Patch is a musician. Davis is planning on sharing Jericho's letter to the David Sharder, Dean of the College of Music as he might have an interested in Patchen speaking with the music faculty.

Building 431 fire tests
An extensive discussion of considerations for fire protection in the LLL mirror fusion test facility (MFTF) is presented. Because of the large volume and high bays of the building, sufficient data on fire detection is unavailable. Results of fire detection tests using controlled fire sources in the building are presented. Extensive data concerning the behavior of the building atmosphere are included. Candidate fire detection instrumentation and extinguishing systems for use in the building are briefly reviewed. (RME)

Energy balance measurements for Shiva
The Lawrence Livermore Laboratory Shiva laser-target interaction facility is designed for experiments at 20 to 30 terawatts. At this power level there will be larger fluxes of neutrons, x-rays, electrons and ions than have been previously measured. The measurements of energy converted into the various reaction products is crucial both in target design and performance analysis of the actual experiment. The total energy absorbed is measured by a box calorimeter surrounding the target except for beam input holes. This measurement prevents the use of other diagnostics, so for normal operation an energy balance module was designed for location on ports on the Shiva target chamber. This module monitors the energy in scattered light at 10640 A and 5320 A or 7118 A. It also contains a faraday cup and plasma and x-ray calorimeters. The distribution of energy in scattered light, plasma and x-rays will be mapped by 58 such modules.

Periodic Intercalibration of Temperature Sensing Elements, Core I, Seed I. Test Results T-641306
BS>Intercalibration data for various temperature sensing elements in the reactor coolant system are obtained and compared with calculated source activity levels and observed channel levels. The readings of 20 of the 62 core thermocouples were either less than 400 deg F, which was off scale on the recorder, or were plus or minus 20 deg F from the calibrating resistance thermometer temperatures. The remainder of the readings were within plus or minus 3% of the temperatures of the calibrating thermometers which were used as a standard of comparison. The main coolant loop resistance thermometers all read within plus or minus 0.2% of the calibrating thermometers. The data from the nuclear source range instrumentation indicated a level ranging from less than 1.7 cps to 31 cps; Channel A indicating the highest. The recorded source activity levels were generally higher than the calculated source activity levels as they should be. There appeared to be no correlation between coolant temperature and source log level source range indications. (N.W.R.)

Establishment and maintenance of a coal sample bank and data base
In the project status report for 4/9/90--7/8/90, Table 2 presented update results of a comparative study of coal sample deterioration in several container types including foil laminate bags. This table contained an erroneous entry (foil laminate bag {minus}20 mesh, alkali extraction 65.4% transmittance). The alkali extraction test on {minus}20 mesh coal stored in foil laminate bags for 52 weeks was repeated in duplicate on another bag (after 64 weeks total storage) resulting in a measurement of 96.2% transmittance. This value has been substituted for the erroneous 65.4% value in the corrected copy of Table 2 enclosed with this report. All values of the alkali extraction and Gieseler fluidity tests indicate that the state of preservation of sample in foil laminate bags is excellent. The samples stored by other methods for comparison purposes all showed significant loss in fluid characteristics. One new whole-seam channel sample of the hvAb Pittsburgh seam coal, DECS-12, was collected July 25, 1990 in Greene County, PA. This sample was placed in 30-gallon steel barrels with high-density lid gaskets and purged with argon at the mine. Upon return to Penn State it was promptly processed so that Gieseler fluidity and other routine analyses could be performed.

Shiva optical diagnostics
In the laser fusion program at Lawrence Livermore Laboratory, no target experiment is complete unless it is complemented by careful measurements of the laser pulse that irradiates the target. For this purpose, an incident beam diagnostics (IBD) package has been designed for the Shiva laser. The package will furnish data on items such as the total energy and the focusable energy out of the laser chain, and the spatial and temporal energy and power distribution at the target plane. Understanding laser-plasma interactions requires knowledge of the amount of 1.06 ..mu..m light energy that is scattered in various directions from the target. The light energy that is scattered toward the beam focusing lens is analyzed by a reflected beam diagnostic (RBD) package containing a calorimeter, a multiple image camera and a TV camera. This paper describes the detailed design and operation of the IBD and RBD packages as tools to align spatial filters and targets, as well as to diagnose the laser beams and target reflectivity.

Energy sensitivity and variability analysis of Populus hybrid short-rotation plantations in northeastern United States. Final report
Production of biomass by corn-like plantations has been demonstrated by a number of researchers. These forest analogs of agronomic cropping systems have the potential to yield substantially more biomass per unit area than traditional forests. Care is needed in choosing the appropriate sites, species, spacing, and harvesting strategies. Opportunities for increased yields have been suggested for fertilization and irrigation. Utilization of the biomass from these dense plantations for energy was the focus of this study. Although the amount of energy potential of the biomass is important, the energy output must be greater than the energy input for biomass to have a positive benefit to society. Further, in order to completely evaluate the net energy of the system it is necessary to examine the energy out-to-in ratios on the basis of usable energy (for example, usable heat, process steam and electricity), as well as all of the energies expended in producing, harvesting, transporting and processing the biomass. The objective of this study is to establish and analyze the energy inputs for selected management strategies in order to evaluate the sensitivity and variability of the energy inputs in the net energy analysis, and based on the net energy analysis to recommend a …

Theory-based transport simulations of TFTR L-mode temperature profiles
The temperature profiles from a selection of TFTR L-mode discharges are simulated with the 1-1/2-D BALDUR transport code using a combination of theoretically derived transport models, called the Multi-Mode Model. The present version of the Multi-Mode Model consists of effective thermal diffusivities resulting from trapped electron modes and ion temperature gradient ({eta}{sub i}) modes, which dominate in the core of the plasma, together with resistive ballooning modes, which dominate in the periphery. Within the context of this transport model and the TFTR simulations reported here, the scaling of confinement with heating power comes from the temperature dependence of the {eta}{sub i} and trapped electron modes, while the scaling with current comes mostly from resistive ballooning modes. 24 refs., 16 figs., 3 tabs.
