Zirconium Hazards Research. Summary Report No. 3655 for September 1, 1956 to August 31, 1957

Description: The sensitivity characteristics of a variety of Zr samples such as sponge, scrap, powder and process materials were studicd. Of particular interest was the determination of the relative seasitivity of these materials to such stimuli as impact, friction, electrostatic discharge, and heat. A study of the zirconium--water reaction at relatively low temperature was initiated. In general, scrap and sponge were relatively insensitive to impact. Only one proeess material, the distillation residue, exh… more

Utilization of the Surface Tension of Liquid Metals in Making High-Vacuum Seals

Description: Abstract: "The free energy (surface tension) of a liquid film can withstand atmospheric pressure across a maximum theoretical gap of 10-(-3) cm between solids if the liquid wets and bridges the sides of the gap continuously. The eutectic alloy of Ga, lm and Sm is used for this purpose. This alloy is molten at room temperature with surface tension > 500 dynes/cm, vapor pressure < 10-(-8) cm at 500 C and excellent wetting properties. This alloy can be utilized in valves, motion seals, flanged joi… more

Study of Small Area Sub-Fabric Flash Burns

Description: In a series of 1850 exposures with a modified 24-in. carbon arc searchlight, the influence of two cotton poplin fabrics alone and in combination with underwear material on the energy required to produce 2+ cutaneous burns in swine were studied. Impregnation of both khaki and green poplin with flre retardant material reduced the amount of energy necessary to produce a 2+ burn below that required with the untreated material, when the fabrics were spaced 2 and 5 mm from the skin. As a fabric is se… more

Drilling in the Flatirons Locality, Monument Valley, Arizona

Description: From introduction: A subsurface exploration program was undertaken to investigate the concentration of uranium and vanadium in or near the base of the Shinarump member of the Chinle formation in the Flatirons locality, and to develop criteria whereby adjacent unexplored areas could be evaluated as to potential production capacity from study of geological and mineralogical features at the host rook outcrop. An earlier study of the area by C. G. Evensen of the U. S. Atomic Energy Commission had s… more
