ELECTRICAL AND OPTICAL INVESTIGATION OF CHARGE-CARRIER TRAPPING IN RUTILE SINGLE CRYSTALS. Technical Report No. 27

Description: Low-frequency abeorption centers, observed by electrical measurements in single crystals of rutile, can be produced by thermal quenching or optical irradiation in the edge of the eigen absorption region (600 A). They are observed when electric fields are applied parallel to the optic axis (crystallographic c axis) and are not visible with the field perpendicular to this axis. The temperature dependence of the principal dispersion indicates an activation energy of 0.18 ev. The centers can be exp… more

Description: Paper presented at Shielding Information Meeting, May 14-15, 1956, Marietta, Ga. This code employs special techniques for the express purpcse of tryirg to obtain reasonable estimates of deep penetrations of gamma rays in an infinite medium emitted from a point monoenergetic source. The code is presently in the debugging'' stage and wlll be tested agninst well known standards before it is used for production. (auth)

SULFOCHLORINATION OF HYDROCARBONS INDUCED BY GAMMA RADIATION

Description: The purpose of this study was to determine the effect of gamma radiation on the direct sulfochlorination of hydrocarbons and nitrobenzene. The radiation source consisted of spent uranium fuel elements, providing a gamma radiation intensity up to 2.5 x 10/sup 6/ roentgen/ hour. The sulfochloriuation studies were carried out either with SO/sub 2/Cl/sub 2/ or with gaseous mixtures of SO/ sub 2/ aud Cl/sub 2/.

Thermal Transient Behavior of the Neutron Sensor of a Reactor Safety Device

Description: The thermal transient behavior of the fuse component of a reactor safety device has been investigated in the KEWB I reactor. The fuse is a neutron flux sensor which, at excessive flux levels, will trip the safety device and cause reactor shutdown. Experimental results on the majority of reactor transients were in good ngreement with calculations. However, on the fastest transients, experimental results were obscured by spurious effects during those intervals when the radiation level was high. l… more

On the Analysis of Bubble Chamber Tracks

Description: Since its invention by Glaser in 1953, the bubble chamber has become a most valuable tool in high-energy physics. It combines a number of advantages of various older methods of particle detection: it offers high spatial resolution, rapid accumulation of data, some time resolution, and some choice of the nucleus whose interaction one wants to study (bubble chambers have been made to operate with a large number of different liquids, including H{sub 2}, D{sub 2}, He, Xe, and several hydrocarbons).… more

CHEMICAL ENGINEERING DIVISION SUMMARY REPORT FOR JANUARY, FEBRUARY, MARCH 1958

Description: Fluoride Volatilization Separation Process. Corrosion tests were made on a variety of metals to find a material of construction suitable for the fluorination step. All metals tested, with the exception of Hastelloy B, were attacked on the permeation of a six-inch graphite crucible by molten NaF- ZrF/sub 4/. Carrier-free tracer experiments were performed on the behavior of Nb and Ru in the fused fluoride process. Pilot plant operations were directed toward development of two operations basic to … more

DISPERSION-TYPE MATERIALS FOR FUEL ELEMENTS. PART I. URANIUM MONONITRIDE AND URANIUM SILICIDE DISPERSION MATERIALS

Description: The basic requirements for dispersion-type fuel elements and the basis for the selection of the components, i.e., melting temperature, density, and uranium-content of the uranium compounds, and melting temperature and absorption cross section of the matrix materials are described. Two types of dispersions are investigated: uranium nitride and uraniuin silicide. Their reactions with Zircaloy-2 and other matrix materials, such as molybdenum, niobium, Nichrome-V, Ti -Nb alloys, or vanadium, are sh… more

HRT BLANKET DUMP TANK PRESSURE

Description: In changing the dumping program for the HRT, it is possible that the entire contents of the reactor will flow into the blanket dump tanks. This study investigates whether the resulting dum system pressure exceeds the allowable limit. For the case of a dump of the entire contents of the HRT high pressure system, commencing two minutes after shutdown from an operating power of 5 Mw and with an average fuel temperature of 280 deg C, into the blanket dump tanks, the resulting maximum presure was ca… more

Pyrometallurgical Purification of Plutonium Reactor Fuels

Description: Pyrometallurgical methods studied are liquation, self-drossing and filtration, slagging by the addition of oxide, carbide, or halide, liquid metal extraction, complete conversion to halide, followed by filtration and selective reduction of the plutonium, and electrorefininng. Experimental techniques and results are presented for each method. (auth)

DYE RETENTION TIME STUDIES IN MODELS OF POSSIBLE HRE-3 CONFIGURATIONS

Description: Dye hold-up time studies were completed for three 1/16-scale lucite models of possible HRE-3 configurations. The models studied had a spherical (#MF- 2) and a cylindrical (#MF-1)(core with flat heads on the pressure vessels. Model MF-2 was also run with a ''dished'' head on the pressure vessel (#MF-2D). Results for these models indicate a change from laminar to turbulent flow when the equivalent Reynolds number was within a range of 900 to 1,500. Better mixing was found in model MF-1 than in MF… more

The Fluorination of Plutonium Tetrafluoride

Description: The fluorination of plutonium tetrafluoride by elemental fluorine to form plutonium hexafluoride was studied in a flow system at temperatures between 100 and 500 deg C. Partial pressures of fluorine from 0.25 to 1.0 atmosphere were used. The plutonium tetrafluoride was obtained from several sources, including the dissolution of uranium-plutonium alloys in bromine trifluoride. Activation energies between 10 and 12 kcal/mole were obtained. Details are included on the techniques and precautions em… more

Ion exchange properties of hydrous oxides

Description: The large class of amorphous insoluble hydrous oxides has interesting ion exchange properties. These materials have high capacities and suitable exchange rates and may therefore be used in packed columns in typical chromatographic (ion exchange) manner. Hydrous oxides may exhibit either cation exchange or anion exchange properties, or both. The type of adsorption depends on the element on which the oxide is based, on the acidity of the medium and, to some extent, on the ion adsorbed. Though som… more

The Influence of the Molecular Mean Free Path on the Performance of Hydrodynamic Gas Lubricated Bearings. Interim Report

Description: A modified Reynolds equation is derived for gaslubricated hydrodynamic bearings operating under ''slip flow'' conditions. Closed analytical solutions are given for a Rayleigh-type step-bearing and an inclined plane slider bearing for the case of two-dimensional flow. The influence of the molecular mean free path on the performance of bearings of arbitrary form is obtained by means of a small parameter, perturbation technique. (auth)

Radiochemical Studies of the Fast Neutron Fission of U$sup 235$ and U$sup 238$

Description: Radiochemical studies of the fast neutron fission of U/sup 235/ and U/sup 238/ have been made in the mass region beyond mass 143 with two neutron energy distributions. These studies provide measurements of the relative fission yields of several chains in the rare earth group in fission of U/sup 235/ and U/sup 238/ caused by neutrons with an energy distribution very close to unmoderated fission neutrons and by neutrons with an energy distribution peaked at 8 Mev. The increased contribution of ve… more

PHOTOSYNTHESIS

Description: The use of tracer carbon, as carbon-14, has made possible considerable progress in the mapping of the routes taken by the carbon atom from CO/sub 2/ into plant substances. The techniques of separation and identification that have made the progress possible lie largely in the region of chromatography and radioautography involving fractional-gamma amounts of material. Most of the earlier steps of carbon incorporation are now known. In addition, a number of the later steps on the routes to amino a… more
