Economic implications of fusion-fission energy systems

Description: The principal conclusions that can be made based on the estimated costs reported in this paper are twofold. First, hybrid reactors operating symbiotically with conventional fission reactors are a potentially attractive supply alternative. Estimated hybrid energy system costs are slightly greater than estimated costs of the most attractive alternatives. However, given the technological, economic, and institutional uncertainties associated with future energy supply, differences of such magnitude … more

Influence of irrigation and weathering reactions on the composition of percolates from retorted oil shale in field lysimeters

Description: Major cations, anions, trace elements and dissolved organic C were measured in percolate from retorted oil shale collected from irrigated lysimeters in the field at Anvil Points, Colorado, over a two year period. The investigations indicated that chemical equilibrium was not established over the monitoring period and major changes occurred in percolate composition as a function of applied water volume and water residence time in the shale. Field and laboratory studies indicated that several fac… more

Materials evaluation for geothermal applications: turbine materials

Description: A number of candidate turbine materials are being evaluated for their resistance to erosion, corrosion, and stress corrosion cracking (SCC) in geothermal brines. These materials include Fe-, Ni-, Co and Ti-base alloys, coatings and ceramics. Tapered wearblades, simulating the leading edge of a turbine blade, are exposed to the direct impact of a two-phase nozzle exhaust. Bent beam SCC specimens, which are constrained in fixtures attached to the wearblade holders, are also exposed to this exhaus… more

Air velocity profiles near sleeve blockages in an unheated 7 x 7 rod bundle. [PWR]

Description: Local air velocity measurements were obtained with a laser Doppler anemometer near flow blockages in an unheated 7 x 7 rod bundle. Sleeve blockages were positioned on the center nine rods to create an area reduction of 90% in the center four subchannels of the bundle. Experimental results indicated that severe flow disturbances occurred downstream from the blockage cluster but showed only minor flow disturbances upstream from the blockage. Flow reversals were detected downstream from the blocka… more

Search for anti-neutrino induced muon+ e- events

Description: The authors have examined 1200 interactions with visible energies greater than 7.5 GeV produced by an anti-neutrino beam in the Fermilab 15-foot bubble chamber filled with a light neon hydrogen mixture. They have found one event with a {mu}{sup +}e{sup -} and hadrons in the final state, but with no evidence of strange particle production. This event may be an example of dilepton production by an anti-neutrino interaction, but other interpretations are possible. With 90% confidence, they conclud… more

Diffraction Radiation by a Line Charge Moving Past a Comb: A Model of Radiation Losses in an Electron Ring Accelerator

Description: A calculation is given of the radiated energy loss from a charged rod which moves at constant speed past an infinite set of parallel semi-infinite conducting plates of infinitesimal thickness, with the rod taken parallel to and at a fixed distance from the plate edges. The problem is analyzed using the Wiener-Hopf technique, and the resulting formulas are evaluated analytically in the limits of high rod speed and low rod speed, and compared with numerical evaluation over the full range of speed… more

DEEP INELASTIC DISTRIBUTIONS IN HIGH ENERGY NEUTRINO COLLISIONS

Description: The results of the analysis of {approx} 1000 {nu} events of the type {nu} + N {yields} {mu}{sup -} + hadrons from the NAL dichromatic beam are presented. Distributions in terms of the scaling variables x = Q{sup 2}/2o{nu} and y = {sup E}n/E{sub {nu}} are presented. The x distribution is compared with F{sub 2}{sup ed} (x) from SLAC; the Q{sup 2} distribution is tested for the presence of the propagator term F{sub 2}(x) {yields} F{sub 2}(x)/(1 + Q{sup 2}/2){sup 2}; and the y distributions are fit… more

Studies of gas phase reactions of uranium with selected oxidizers and fluoromethanes

Description: A crossed molecular beam study was made of the reactions of U with inorganic oxidizers (O/sub 2/, NO, SO/sub 2/, N/sub 2/O, CO/sub 2/), water, alcohols, acetone, and halogenated methanes. Results show that U in the gas phase behaves very much like most other heavy metals, and may be called a heavy Ba or Sn atom. 8 figures. (DLC)

Scanning reference electrode techniques in localized corrosion

Description: The principles, advantages, and implementations of scanning reference electrode techniques are reviewed. Data related to pitting, intergranular corrosion, welds and stress corrosion cracking are presented. The technique locates the position of localized corrosion and can be used to monitor the development of corrosion and changes in the corrosion rate under a wide range of conditions.

Dynamics and control: energy conversion, delivery, and demand analysis

Description: Techniques of mathematical modeling and modern control theory, using microprocessors and advanced measurement and control devices, are extensively applied to components and systems for the conversion and delivery of energy. The projection of energy demands, as a function of economic growth and energy price, is also the subject of active research and analysis. This position paper reviews the current state-of-the-art of analysis in these areas dealing with the planning and operation of energy sys… more

Precision measurement of annihilation point spread distributions for medically important positron emitters

Description: An experiment using very thin sources in low density polyurethane foam to expand the annihilation point spread distributions by linear factors of 20 and 50 was designed. By placing the same sources in an aluminum cylinder, range effects are effectively suppressed and broadening from all other sources may be measured. Three positron sources were used: C-11, Ga-68 and Sr-82, having beta end-points of 0.96, 1.90, and 3.35 MeV respectively. The sources were evaporated from solutions of small volume… more

Deposition of aluminum--copper alloy on laminated polyimide substrates from a RF induction source

Description: A physical vapor deposition process with a rf induction vapor source has been developed to deposit 11.2-..mu..m Al--Cu alloy on polyimide laminate substrates. The average thickness uniformity (standard deviation/average thickness) of the deposit acquired by a beta backscatter technique was approximately 1% for these deposits. The Al-0.3 wt % Cu vapor charge results in a Cu content in the deposit of 0.12 wt %. The Cu shows no preferential deposition pattern, as related to the surface of the lami… more

Treatment methods for geothermal brines

Description: A survey is made of commercially available methods currently in use as well as those which might be used to prevent scaling and corrosion in geothermal brines. More emphasis is placed on scaling. Treatments are classified as inhibitors, alterants and coagulants; they are applied to control scaling and corrosion in fresh and waste geothermal brines. Recommendations for research in brine treatment are described.

Data analysis for nuclear materials accounting

Description: Materials accounting for special nuclear material in future fuel cycle facilities will draw heavily on sophisticated data-analysis techniques. Decision analysis, which combines elements of estimation theory, decision theory, and systems analysis, can be used to reduce errors caused by subjective data evaluation and to condense large collections of data to a smaller set of more descriptive statistics. The methods and requirements of decision analysis are discussed and illustrated by a conceptual… more

Martensitic Transformation in High Magnetic Fields

Description: The kinetics of the isothermal martensitic transformation in Fe--29.6 Ni and Fe--22.5 Ni--4 Mn alloys were investigated as a function of constant magnetic fields, ranging up to 140 KOe (11 x 10/sup 6/ ampere/m). The principal role of the applied magnetic field is to increase the free-energy difference between the product and parent phases in these iron-based alloys, and so the transformational driving force for a given composition can be varied even at a fixed temperature. In the Fe--Ni alloy, … more
