Research and Development in the Field of Thorium Chemistry and Metallurgy. Monthly Progress Report for May 16 Thru June 15, 1955

Description: An internally heated chlorinator using a bed of graphite as a resistor element in contact with molten salt was shown to be feasible. An extended run was completed in an electrolytic cell demonstrating the feasibility of continuous operation. Other studies are reported on chlorination of thorium oxycarbonate and physical metallurgy evaluations of the Th produced. (T.R.R.)

INVESTIGATION FOR THE PRODUCTION OF THORIUM METAL. Technical Progress Report--Fifth Quarter

Description: Processes for preparing a suitable ThCl/sub 4/ electrolyte free of H/sub 2/O and C/sub 2/ were investigated including chlorination with C -Cl/sub 2/, sulfur chlorides, NaCl, and preparation from anhydrous solvents. The method selected consisted of reacting ThOCO/sub 3/ with HCl, adding NH/sub 4/Cl, and heating in inert atmosphere to drive off NH/sub 4/Cl. (T.R.H.)

The System Zirconium-Iron-Tin. Status Report No. 4 for July 1, 1957- March 31, 1958

Description: A study of the solubility limits of iron and tin in alpha zirconium at temperatares below 500 deg C is in progress. Dilute alloys were prepared by arc- melting using the highest purity materials. Heat treatment of the alloys involves homogenizntion at 800 deg C followed by severe cold work prior to extended anneals at temperatures between 200 and 500 deg C in 50-degree intervals. Metallographic examination of annealed and quenched structures is the primary mode of investigation. Some magnetic s… more

Fabrication of Dispersed Uranium Fuel Elements Using Powder-Metallurgy Techniques

Description: Fabrication techniques for producing dispersion fuel elements with cores of 30 volume per cent of UC, U/sub 2/Ti, U/sub 3/Si, or U/sub 6/Ni dispersed in Zircaloy 2 and 30 volume per cent of UC or UN dispersed in Type 18-8 stainless steel have been investigated. Roll-clad plate-type elements of all these compositions may be fabricated by powdermetallurgy methods in such a manner that good core-tocladding bonds and cores with uniform dispersions of discrete uranium- compound particles are obtaine… more

Development of Zirconium Alloys. Part 1

Description: A number of alloys of zirconium have been investigated as part of a program aimed at improving the high-temperature tensile strength of zirconium. These alloys include molybdenum, tantalum, tungsten, tin, titanium, and nitrogen alloys. It was found that small additions of molybdenum, tantalum, tin, titanium, and nitrogen appreciably increase the high-temperature tensile strength of zirconium.

Zirconium Pilot Plant Research and Development. Progress Report

Description: A summary of the work which was done on the small pilot plant during the week's operation shows the following: (1) High vaporization rates can be obtained from a vibrating flash plate. (2) Feeding powder to the plate at a constant and controllable rate presented some difficulty. This may be overcome by pumping between Victoprene seals, proper outgassing of the powder, using a smaller diameter screw, and sloping the feed screw upward to avoid translation of the powder by vibration. (3) Depositio… more
