Welding uranium with a multikilowatt, continuous-wave, carbon dioxide laser welder

Description: A 15-kilowatt, continuous-wave carbon dioxide laser was contracted to make partial-penetration welds in 6.35-and 12.7-mm-thick wrought depleted uranium plates. Welding power and speed ranged from 2.3 to 12.9 kilowatts and from 21 to 127 millimeters per second, respectively. Results show that depth-to-width ratios of at least unity are feasible. The overall characteristics of the process indicate it can produce welds resembling those made by the electron-beam welding process.

Multivariate Ornstein--Uhlenbeck process in studies of home range. Technical report No. 2. [Radiotelemetry tracking of birds, deer, and coyotes]

Description: In home range studies, the statistical analysis of radio telemetry data poses special problems due to lack of independence of successive observations along the sample path. Assuming, however, that such data is generated by a continuous, stationary, Gaussian process possessing the Markov property, then a multivariate Ornstein-Uhlenbeck diffusion process is necessarily the source and is proposed here to be a workable model. Its characterization is given in terms of the typical descriptive propert… more

High performance metal/air fuel cells. Part 1. General review. [Li, Al, Ca, Cd, Mg]

Description: Metal/air fuel cells are reviewed in terms of their potential application in electric vehicles. Attention is focused on those metals (light alkali and alkaline earth metals, and aluminum) which, in combination with oxygen, have theoretical energy densities (2--13 kWh/kg-metal) exceeding that of gasoline (utilized in automobiles at 2--3 kWh/kg). Lithium and aluminum have yielded 8- and 4 kWh/kg, respectively, in laboratory experimental cells. The slurry Zn/air system achieves 0.85 kWh/kg-Zn in p… more

Thermal stress analysis of HTGR fuel and control rod fuel blocks in the HTGR in-block carbonization and annealing furnace

Description: A new approach that utilizes the equivalent solid plate method has been applied to the thermal stress analysis of HTGR fuel and control rod fuel blocks. Cases were considered where these blocks, loaded with reprocessed HTGR fuel pellets, were being cured at temperatures up to 1800/sup 0/C. A two-dimensional segment of a fuel block cross section including fuel, coolant holes, and graphite matrix was analyzed using the ORNL HEATING3 heat transfer code to determine the temperature-dependent effect… more

In-situ drying process test proposal

Description: To determine if in-situ drying is a practical method of removing the nonrecoverable interstitial liquid, a process test is needed. By reducing the tank ventilation rate, the salt cake or sludge will increase in temperature and more moisture can be evaporated. As long as the air flow rate is great enough to replace the moisture laden air with ambient air, the moisture removal rate (MRR) should increase. The maximum MRR will be determined by reducing the flow rate in a stepwise procedure. Tanks 1… more

Thermal and nuclear design review of the NRX-A5 Reactor

Description: A thermal and nuclear NRX-A5 Design Review was held at WANL on April 10, 1964. Analyses and planning performed to date on the NRX-A5 and subsequent reactors were presented. Systems analyses were performed on various "cooled periphery".and "hot periphery" seal configurations. A number of inner reflector designs were examined, as well as means for cooling the lateral support springs. Core component redesign incl,uded methods for controlling inter-element pressure distribution by undercutting or c… more

Corrosion-induced acoustic emissions from uranium 4.5--weight percent niobium binary alloy

Description: The ability to monitor corrosion and stress-corrosion cracking of uranium 4.5-weight percent niobium was investigated. The acoustic emissions from stress-corrosion cracking were monitored using smooth four-point bend specimens, which were immersed in oxygen-saturated water containing chloride ions. The acoustic emissions from corrosion were monitored from rectangular corrosion coupons. These latter specimens were exposed to nitrogen-saturated and oxygen- saturated solutions of distilled water a… more

Biphase turbine bottoming cycle for a diesel engine

Description: Application of a two-phase turbine system to waste heat recovery was examined. Bottoming cycle efficiencies ranging from 15 to 30% were calculated for a 720/sup 0/F diesel exhaust temperature. A single stage demonstration unit, designed for non-toxic fluids (water and DowTherm A) and for atmospheric seals and bearings, had a cycle efficiency of 23%. The net output power was 276 hp at 8,100 rpm, increasing the total shaft power from 1,800 hp for the diesel alone, to 2,076 hp for the combined sys… more

Kinetics and mechanism of desulfurization and denitrogenation of coal-derived liquids. Fourth quarterly report, March 20--June 20, 1976

Description: The high-pressure liquid-phase flow microreactors are operating satisfactorily in both hydrodesulfurization and hydrodenitrogenation studies after minor modifications to allow in situ sulfiding. The hydrodesulfurization of dibenzothiophene occurs by a simple network giving only H/sub 2/S and biphenyl as primary reaction products. The reaction network for quinoline hydrodenitrogenation has been determined, and a kinetic model developed to allow quantitative determination of the first-order kinet… more
