Study of structure of nuclei with neutrons and nuclear data measurements for MFE. Progress report, September 1, 1979-August 31, 1980

Description: Measurements of neutron differential elastic and inelastic scattering cross sections have been made for /sup 6/Li, /sup 7/Li, /sup 11/B and /sup 13/C. For /sup 7/Li + n, a multichannel R-matrix analysis has been completed, providing much new structure information for the compound /sup 8/Li system. These results are in very good agreement with recent theoretical model calculations, so that together the two provide considerable advancement in the state of our knowledge of /sup 8/Li. R-matrix analyses of /sup 11/B + n and /sup 13/C + n elastic scattering data have also been completed. For /sup 13/C + n theoretical model calculations have also been carried out and comparisons of these theoretical results with the R-matrix analysis are made. The triplet quadrupole spectrometer (TQS) is now fully operational. Development of new detectors, techniques, data analysis codes and theoretical model codes for use with the TQS system is complete. Measurements of (n,z) cross sections for fusion reactor structural materials e.g. /sup 58/Ni are currently underway. Construction of the long-flight-path tunnel for the swinger magnet facility has begun and development for this facility will continue in the coming year.

Cadmium sulfide/copper selenide cell research. Copper selenide-based thin film solar cells. First quarterly technical progress report, June 1-September 1, 1980

Description: The objective of this program is to investigate the use of Cu/sub 2-x/Se to produce low cost, high efficiency photovoltaic solar cells. The goal is to: (1) develop a polycrystalline thin film photovoltaic device capable of 10% conversion efficiency, and (2) demonstrate feasibility of large scale production at a cost of approximately $0.30/watt. The Cu/sub 2-x/Se films are produced by coevaporation of Cu and Se from separate, individually controlled vapor sources onto heated glass substrates. This method gives greater composition controllability and is readily adaptable to large scale production efforts. Two quartz crystal microbalances are used to separately monitor the Cu and Se deposition rates. The structural, electrical, and optical properties of the Cu/sub 2-x/Se films have been measured for deposits made on 250/sup 0/C substrates. The optical absorption measurements shows the material having an indirect band gap of 1.4 ev and a direct gap of 2.2 ev. These values are for stoichiometric indices in the range of 0.17 less than or equal to x less than or equal to 0.26. Hall and conductivity measurements give hole mobilities in the range of 3-7 cm/sup 2//Vsec and hole densities of the order of 4 x 10/sup 22/ cm/sup -3/. For deposits made on substrate at 160/sup 0/C, the mobility is in the range of 3 to 10 cm/sup 2//Vsec and hole densities on the order of 10/sup 19/ to 10/sup 21/ cm/sup -3/ for 0.1 less than or equal to x less than or equal to 0.3. To date, the best cell has photovoltaic characteristics of J/sub sc/ = 11.6 mA/cm/sup 2/, V/sub oc/ = 460 mV, F.F. = 0.62 and eta = 3.3% as tested under simulated AM1 illumination.

Design considerations for a steady state fusion reactor's thermal energy dump (TED) with emphasis on SAFFIRE

Description: This work examines the use of a thermal dump to handle the severe particle and energy handling requirements of a diverted plasma. We outline a general approach for evaluating the design parameters and limitations of a thermal dump, considering such things as thermomechanical and erosion effects, compatibility, availability, machinability, coolant recirculation, vacuum pumping, economics, lifetime, etc. To demonstrate how the performance requirements are reflected in design decisions, we apply a solid-walled dump to a small-sized field reversed mirror (FRM). We also examine a liquid-lithium droplet thermal dump and point out some distinct advantages of this new concept over the solid-wall design in reducing stress, erosion, and vacuum pumping problems. The chief disadvantages of this scheme include liquid-metal safe-handling problems, vapor pressure-temperature limitations, and the need for differential pumping if T/sub Li/ > 310/sup 0/C is desired.

Assessment of the geothermal resources of Carson-Eagle valleys and Big Smoky Valley, Nevada. First annual report, May 1, 1979-May 30, 1980

Description: Two geothermal investigations were completed in three Nevada locations. The regions studied were selected from areas outlined as having direct utilization potential (Trexler and others, 1979) and included the Carson-Eagle Valley, Bis Smoky Valley and Caliente. Studies were organized around the completion of a group of tasks in each area. These tasks included: geologic reconnaissance, gravity surveys, aerial photography, fluid sampling and analysis, shallow depth temperature probe surveys, soil mercury surveys, shallow electrical resistivity measurements, and temperature gradient hole drilling. Goals of the project were to provide regional information about the nature and extent of the resources and to offer a critical evaluation of the techniques employed. Results from the work in the Carson-Eagle Valley and Big Smoky Valley are presented. (MHR)

Chemical Engineering Division fuel cycle programs. Quarterly progress report, October-December 1978

Description: In the program on pyrochemical and dry processing methods (PDPM) for nuclear fuel, tungsten crucibles were successfully spun for use in laboratory-scale experiments. Corrosion testing of refractory metals and alloys in PDPM environments was done. Ceramic substrates were successfully coated with tungsten. Solubility measurements were made to determine Cd/Mg alloy composition and temperature at which dissolved Th will precipitate. Experiments were started to study the reduction of high-fired ThO/sub 2/ with Ca in a molten metal-molten salt system. Work on the fused salt electrolysis of CaO was started. Equipment for determining phase diagrams for U-Cu-Mg system was set up. The reaction of UO/sub 2/ with molten equimolar NaNO/sub 3/-KNO/sub 3/ was studied as part of a project to identify chemically feasible nonaqueous fuel reprocessing methods. Work was continued on development of a flowsheet for reprocessing actinide oxides by extracting actinides into ammonium chloro-aluminate (and alternative salts) from a bismuth solution. Preparation of Th, U, and Pu nitrides after dissolution of spent fuel elements in molten tin is being studied. Leach rates of glass beads, pulverized beads, and beads encapsulated in a lead matrix with no protective envelope were studied. A method (employing no pressure or vacuum systems) of encapsulating various solid wastes in a lead metal matrix was developed and tested. A preliminary integration was made of earlier data on effects of impacts on metal-matrix waste forms.Leach migration experiments were compared with conventional infiltration experiments as methods of evaluating geologic formations as barriers to nuclide migration. The effect of the streaming potential on the rates of transport of radioactive I/sup -/ and Na/sup +/ through kaolinite columns was measured, as well as adsorption of iodide and iodate by several compounds; implications of the results upon the disposal of radioactive iodine are discussed.

Numerical modeling of the EBT-S ion-cyclotron heating experiment

Description: To determine the effect of ion-cyclotron heating on EBT-S plasma parameters, a one-dimensional, time dependent neoclassical model of plasma particle and energy transport was used. For EBT-S the code was run with the following parameters: B/sub O/ = 0.7 tesla (axial field at the midplane), B/sub O/ = 1.4 tesla (axial field at the throat), R/sub T/ = 150 cm (major radius), a = 15 cm (minor radius at the midplane).

Plasma-assisted CVD of fluorinated, hydrogenated amorphous silicon. Final technical report, September 15, 1979-September 15, 1980

Description: During the past year, approximately 300 large-area (400 cm/sup 2/) PIN hydrogenated amorphous silicon (a-Si:H) solar cells were fabricated and tested. a-Si:H PIN cells which were plasma deposited at 200/sup 0/ to 350/sup 0/ were found to have high internal currents (13mA/cm/sup 2/), whereas those which were deposited by CVD at 500/sup 0/ to 650/sup 0/C had low internal currents. When corrected for optical losses in the top electrode, the internal quantum efficiency vs wavelength for the PIN cells indicated a peak value above 80% at about 525nm, which decreased monotonically to zero at about 725 nm. When the published values of RCA and EXXON were corrected similarly for optical loss, nearly identical values of internal quantum efficiencies were found. Calculations based on a model proposed by Cody et al of EXXON indicated that the depletion width was less than 0.4 microns for all PIN cells, thereby limiting junction efficiency in the red portion of the solar spectrum since the 1/e photon range exceeds this value. A novel inverted NIP cell was tested and found to have its maximum quantum response shifted to 625 nm. Also, an amorphous boron (a-B) layer deposited on a-Si:H to form a PIN heterojunction improved blue response and Voc. A combination of the red-responsive cells and the a-B heterojunction cells could raise efficiency to 8%.
