Evaluation and Consolidation of Electrolytic Thorium

Description: Abstract: "Sound, fabricable ingots of thorium were produced by triple are melting of electrolytic thorium. Consumable electrodes were fabricated by tack welding of cold-pressed and vacuum-sintered bars of the granular thorium electrodeposited from a molten-salt bath. The hydrogen content of the electrodeposited material was reduced from 80 to 4 ppm by vacuum sintering at 1250 C at pressures below 1 x 10-(-3) mm of mercury. Both sodium and chlorine content were reduced during melting; sodium fr… more

Effects of Ultraviolet Radiation on Chloroplast Reactions and Plant Metabolism

Description: This technical report represents a brief survey of work by this project on the effects of ultraviolet radiation (UV) on certain of the photochemical and metabolic properties of rhubarb chard and sugar beet (Beta vulgaris). These plants were selected for this work because for some years they have been used as sources of chloroplasts for Hill reaction studies in this laboratory. Some of this work has appeared as a brief paper.

The Alpha Half-Life of the Isotope Pu-241

Description: A plutonium solution of known Pu-241 content was purified by solvent extraction techniques to remove uranium and americium impurities. Portions of this purified solution were then analyzed for U-237 as a function of time. Since the growth of U-237 occurs directly by the alpha decay of Pu-241, these measurements provided sufficient data for calculation of the Pu-241 alpha half-life, which was found to be 2.91 ± 0.50 x 10⁵ years.

Final Report Production Test 105-585-A Functional Testing of Teflon Flexible Connector, 105-C Type

Description: A new type of flexible hose connector consisting of a Teflon tube enclosed in a stainless steel wire braid sheath was proposed for use on 105-C rear face in late 1954. A test was initiated to determine the suitability of Teflon, and specifically Fluoroflex Teflon compound for rear face application. Probable useful life limit is estimated at 10⁶ R, which would be attained in about three years in contact with fresh effluent.

The Study of a Method of Assaying the Approximate Isotopic Ratio in Uranium

Description: A method for determining the appropriate isotopic content of uranium-235 in uranium slugs has been investigated. In the conduct of the experiment it was found that there was a background counting rate several times the counting rate of the phenomena under study. Methods are suggested for improving the counting rate and reducing the background. The conclusions at this time are that reactivity determinations will provide the most rapid and precise measure of U-235 content in uranium.
