Supersonic Two-Dimensional Jet-Interaction Studies

Description: Abstract: The report describes the results of an experimental study involving the injection of a gaseous secondary jet into an unbounded supersonic flow field which was uniform outside of a turbulent boundary layer. The investigation was principally concerned with the formulation of the shock wave shapes and streamline patterns to be associated with typical turbulent, two-dimensional jet-interaction flows. In support of this objective, results are presented for a Mach 5 test conducted using a f… more

Earth Vibrations from a Nuclear Explosion in a Salt Dome

Description: The following report presents data from the SALMON experiment, an experiment made to study the mechanics of a tamped nuclear detonation in a salt dome in terms of generated shock waves as they are propagated out of the dome and progressively through the crust and mantle of the earth. This experiment was made in the Tatum salt dome, Mississippi, October 22, 1964.

Reactions of the Hydrated Electron

Description: Abstract. The rate constants for the reaction of the hydrated electron eaq with a number of solutes and with radicals formed in water radiolysis are reported. Hydrated electrons were formed in the electron pulse irradiated solutions at concentrations in the range from 1 to 10 pM. Their reaction was followed by the decay of the optical absorption of eaq at 5780 A. Generally a 04 psec pulse of 15 MeV electrons was used. In the absence of eaq scavengers, second-order kinetics prevailed owing to th… more

Comparison of Radiation-Induced Graft Copolymerization Untilizing Electron Accelerators and Isotope Sources as Radiation Initiators

Description: "A brief examination of the post irradiation grafting of machine irradiated polyethylene film with acrylic acid monomer was made. Evidence of postgrafting was detected in samples that had been irradiated to a total dose of 10 Mrads at a dose rate of 0.01 Mrad/sec. and then exposed to a 25% purified acrylic acid solution in benzene for periods of 1 to 4 days."

Internal Conversion Coefficients of the 2+-0+, E2 Transitions in Even-Even Sm152[over]90 and Gd152[over]88

Description: From abstract: "To investigate the deviation of the internal conversion coefficients of E2 transitions from theoretical computations and their dependence on nuclear deformation, the total internal conversion coefficient of the 121.8-kev 2+-0+ transition in ellipsoidal Sm152[over]90 was measured to be 1.135 ± 0.010 with a high accuracy coincidence-sum method. The K-shell to total internal conversion ratio was determined to be 0.588 ± 0.003 with a [beta] spectrometer...The experiment revealed no … more

The Proton-Proton Triple Scattering Parameters R and A at 213 Mev

Description: "As a part of a program to determine the p-p scattering matrix at 213 Mev, the triple scattering parameters R and A were measured at 30, 40, 50, 60, 70, 80. and 90 deg in the center-of-msss system. The results are compared with a phase shift analysis by MacGregor and Moravcsik and with the predictions of the boundary condition model of Saylor, Bryan and Marshak."

Proposal for an Advanced Engineering Test Reactor : ETR II

Description: Report containing "the results of a study which was directed at providing additional experimental loop irradiation space for the AEC-DRD testing program. It was a premise that the experiments allocated to this reactor were those that could not be accommodated in the MTR, ETR or in existing commercial test reactors" (p. 5).

Isotopic Sources of Secondary Radiation : Interim Technical Report Covering the Period from June 15, 1958 to March 1, 1959

Description: During the first eight months of this program the emphasis has been places on experiments and calculations on the x-ray target configurations and materials. We have found, by extending the experimental information using Pm147, Kr85, and Sr90-Y90, as well as by developing the theoretical x-ray production for these sources, the approximate conditions under which isotopic sources will emit nearly monochromatic x-rays suitable for gaging and radiographic application in the 10 to 100 Kev photon ener… more

Results of Parallel Flow Oscillator Studies. Progress Report No. 2

Description: From the results of the tests it is clear that changing from series to parallel flow effects little or no change i the nature of the reactivity feedback. The physical processes which characterize the magnitude and time dependence of the negative power coefficient of reactivity are apparently identical in both instances. Accordingly, it is reasonable to infer that the conclusions reached as he result of the series flow studies are still valid. These are :(1) the overall power (temperature) coeff… more

Injection Trajectories and Beam Matching for the Cambridge Electron Accelerator

Description: "ABS>Injection trajectories were calculated for different injection conditions for the Cambridge Electron Accelerator, considering also the effect of magnetic fringing fields. The general problem of matching the emittance of the linac to the acceptance of the synchrotron in the transversal phase space is considered, and it is shown that this can be done by a set of two quadrupole lenses. In order to eliminate rudial betatron oscillations due to energy deviations of the injected particles, a pul… more

Development and Properties of Uranium Monocarbide Cermets : Final Report

Description: Abstract: "Uranium monocarbide-Zircaloy II alloy cermets were developed and tested for chemical and physical properties. It was determined that pure uranium monocarbide can be prepared by vacuum are melting techniques. Following melting, the combination, hot pressing, and corrosion behavior of dense monocarbide has been studied. The preparation of uranium monocarbide-Zircaloy II cermet bodies was investigated by means of hot pressing, cold pressing and sintering, warm pressing, extrusion, and h… more

Precision Beta-Ray Spectroscopy : Termination Report

Description: Detailed information on the radiations associated with several even-even isotopes has been obtained. In some instances enough information has been gathered to allow construction of skeleton energy level diagrams for the isotopes. Activities studied were obtained from pile irradiation of pure odd-even natural isotopes and included Dy160, W182, Sm152, Gd152 and Gd154. Details of the work done on and results obtained for these isotopes are reported in section 3. Some analytic and experimental stud… more

Separation of Zirconium & Hafnium : Proposal for Construction & Operation of Zirconium Production Plant

Description: Abstract: A re-evaluation of the cost of producing essentially hafnium free zirconium as zirconium oxide at a rate of 150,000-200,000 pounds zirconium per year by solvent extraction of the metal thiocyanates in a permanent plant has been made. Using part of the present temporary facilities, the cost, with five year amortization of the plant, will be $3.15 per pound zirconium. A by-product of the mixed oxides of hafnium and zirconium, having at least fifty percent hafnium and perhaps as high as … more

Safety Analysis of the Storage and Handling of the SRE Fuel

Description: "The most hasardous conditions relating to the storage and handling of the SRE fuel are those in which water and fuel form a possible critical assembly. Therefore, this memorandum is primarily devoted to an analysis of the conditions necessary for a critical mixture of water and SRE fuel. Certain special geometries are then analyzed for their safeness."
