Abstract: "Aluminum-clad nickel-plated uranium is corrosion resistant in boiling water. Samples with intentional defects in the aluminum-nickel clodding layers, after testing for more than 300 hr. showed no sign of rapid failure. The study of electroplated metals on uranium for aluminum cladding has defined the effects of several processing variables on the corrosion resistance. The quality of the uranium and the quality of the aluminum-nickel bond were important. Heat treatment and vacuum outgassing of the nickel-plated uranium prior to aluminum cladding were beneficial, and minimizing the amount of air present in the hot-press assembly was desirable. Variation in the steps for electroplating on uranium did not affect the corrosion resistance of aluminum-clad uranium."

Abstract: "A cylindrical coil has been designed for pulsed field operation suitable for use in a model thermonuclear reactor. The coil has an eight-inch inside diameter and a length of fifty-one inches. Magnetic mirrors at the ends consist of double-layer solenoids six and one-half inches long designed to slip over the main coil. Subsequent models of this coil have been fabricated which improved the electrical insulation provided by the bonding materials and the mechanical rigidity of the coil. Peak central fields of fifteen kilogauss and mirror fields of thirty kilogauss have been obtained."

Forty-eight ``half-dollar`` size corrosion specimens were press-clad at 950 F for 5 minutes with 3, 4, 5, and 6 thousand psi to establish a standard sample for the evaluation of the effects of outgassing on the corrosion resistance of nickel-plated uranium. Materials are on hand for the fabrication of tools with which to carry out preliminary work on the internal cladding of natural uranium tubes. At a meeting with BMI and du Pont personnel, Mr. DeBuigne of Moczik Tool and Die Co. recommended a co-axial method for extrusion-cladding uranium plates. Design and fabrication of tools for this work would be done by Moczik.
