Structural Response and Permanent Displacement Measurements

Description: Measurements and visual observations made during the Hardtack II series of underground shots provide basis for conclusions regarding shock-resistant design of protection for cavities in rock and qualitative prediction of permanent displacements in rock due to nuclear detonations. Vibration measurements on blast-resistant construction in soil provided non-nuclear test results which apply to shock resistant design. With varying soil cover, the compressive mode predominated in arch structures and … more

CHEMICAL ENGINEERING DIVISION SUMMARY REPORT FOR JANUARY, FEBRUARY, AND MARCH 1957

Description: Fluoride Volatilization Separations Process. Development of a fused fluoride process for dissolution of uranium-- zirconium fuel alloys continued. In corrosion tests to find a suitable container material, Ni was found to be susceptible to a sulfur-type attack. Hastelloy B showed promise, and graphite offers excellent chemical resistance but poor mechanical strength. The dissolution rate of Zr in NaF-- ZrF as affected by impingement of the HF sparge was studied. Production of UF/sub 6/ by fluidi… more

METALLURGY DIVISION QUARTERLY PROGRESS REPORT FOR PERIOD ENDING OCTOBER 31, 1952

Description: Physieal Metallurgy. In the study of Th alloys, it has been found that the addition of Nb and V to Th produces a slight strengthening effect with the first small additions, but that large additions result in a lowering of strength with corresponding increases in ductility. The melting point of iodide Th was measured as being 1755 deg C. Studies of a series of Th--C alloys, with C content up to 0.13%, indicate that C does not affect the temperatures for the start and completion of recrystallizat… more

On the Problem of Liquid Entrainment

Description: THe problem of liquid entrainmment by a gas phase is considered with the purpose of gathering, presentinf, and correlating available information which may be useful for predicting the liquid carry-over in a boiling water reactor at high pressure. Correlations which predict water carryover as a function of pressure, of the height of the vapor dome, and of the vapor mass flow rate are presented and discussed. Because entrainment depends upon the hydrodynamic conditions and upon the expansion of a… more

A Description of Thermal Conductivity and Dynamic Viscosity of Water in the Critcal Region

Description: A study to establish reasonable estimates of the values of thermal conductivity and dynamic viscosity of water in the critical region was conducted. This was accomplished by reviewing the literature and utilizing available experimental measurements. The validity of the estimates was strengthened by the use of the principle of corresponding states after other considerations failed to contribute a description of these two transport properties in the critical region. The final results were express… more

Mixing of a Cold Liquid Jet With a Boiling Liquid Stream

Description: The turbulent mixing of a cold liquid jet with a stream of vapor bubbles and saturated liquid is analyzed for a single axial liquid jet. The cases where the issuing jet velocity is very much greater than and nearly equal to the free stream velocity are considered. Transport of axial momentum and of scalar quantities in the stream are calculated and the results applied to the transport of enthalpy in a bubbly mixture. (D.L.C.)

Radioactive Waste Disposal System Periodic Radiation Monitoring Survey. Core I, Seed 1. Test Results T-612075. Section 2

Description: The radiation level of all permanently installed mom-tored points in the Hadioactive Waste Disposal Plant was determined periodically, and the effectiveness of shielding facilities in working areas at times during which the radiation level was above limits set up by Health Physics was checked. The radiation level in all areas surveyed was less than 5 mr/hr, which is the Health Physics' limitation for the Radioactive Waste Disposal Area. Any area with a level abeve 5 mr/hr is a controlled access… more

Synthesis and Fabrication of Refractory Uranium Compounds. Monthly Progress Report No. 10 for September 1 Through September 30. 1960

Description: Several synthesis experiments were carried out to provide a stock of U/ sub 3/Si/sub 2/, powders for fabrication of test specimens. Initial thermal- expansion characteristics were determined on U/sub 3/Si/sub 2/ bars. High densities were obtained in the preparation of UN bodies. Thermal-expansion tests were made on bars of UN with a high-density silicon carbide tube dilatometer in a flowing argon atmosphere. (W.L.H.)

Measurements of Dissolved Hydrogen Concentration. Core I, Seed 1. Test Results T-612395-A

Description: Measurements were undertaken to compare the performance of a hydrogen- palladium diffusion coil to a palladium resistance wire assembly in measuring hydrogen concentration and to obtain data to evaluate a Swartout Palladium Resistance Gage electronic readout unit. No comparison could be made since the instruments were never in satisfactory service at the same time. The data taken with each instrument are compared with data determined by laboratory analysis. A review of the data indicated that t… more

The Scattering of Positrons by Atomic Hydrogen: Formulation

Description: The derivation of the coupled systems of second-order integrodifferential equations which must be solved numerically in order to obtain the cross sections for the elastic and inelastic scattering of positrons by atomic hydrogen and the cross sections for the formation of positronium into the 1s and 2s states is considered. The numerical method to be used to solve the equations at incident energies above excitation thresholds is also discussed. (auth)
