Separation of Zirconium & Hafnium : Proposal for Construction & Operation of Zirconium Production Plant

Description: Abstract: A re-evaluation of the cost of producing essentially hafnium free zirconium as zirconium oxide at a rate of 150,000-200,000 pounds zirconium per year by solvent extraction of the metal thiocyanates in a permanent plant has been made. Using part of the present temporary facilities, the cost, with five year amortization of the plant, will be $3.15 per pound zirconium. A by-product of the mixed oxides of hafnium and zirconium, having at least fifty percent hafnium and perhaps as high as … more

Zirconium-Hafnium Separation : Mixer-Settler Studies : Final Report

Description: Abstract: Use of the mixer-settler apparatus as a rapid means of determining improved conditions for plant operation is described including the experimental details. The preparation of highly purified samples of both zirconium oxide and hafnium oxide is discussed. (This document is concerned almost entirely with explorations of small scale continuous systems. Another document dealing with this general problem using small scale batch operations is being published simultaneously. It should prove … more

Interim report, Production Test 105-522-E, Examination of pile process tubes removed from 100-C, D and F piles

Description: This report covers the examination of thirteen process tubes seven from F Pile, three from C Pile and three from D Pile. Five of the thirteen tubes were removed because they were leakers, four from F Pile and one from C Pile. One tube from F Pile and one from D Pile were removed. Reactor Section had requested the removal of two from F Pile to check for external corrosion. Two tubes, small diameter old pile annulus, were removed from C Pile under PT 105-519-E, ``Raising Permissible Outlet Water … more

WORLD-WIDE FALLOUT FROM OPERATION CASTLE

Description: A world-wide network of gummed film stations was established to monitor fall-out following Operation Castle. Although meteorological data were poor, a general connection of tropospheric flow patterns with observed fall-out was evident. There was a tendency for debris to remain in tropical latitudes, with incursions into the temperate regions associated with meteorological disturbances of the predominantly zonal flow. As the season advanced, such incursions became more evident. Outside of the tr… more

An experimental study of a method for designing fuselage side air inlets for high performance at transonic and low supersonic speeds

Description: Report presenting a brief experimental investigation of a method for designing fuselage side air inlets with high internal total-pressure recovery and zero spillage drag at a specified design inlet mass-flow ratio. With a scoop designed according to the concept, near-zero spillage drag can be attained at the design inlet mass-flow ratio through a range of Mach numbers. Results regarding pressure recovery and drag due to the scoop are provided.

Lift Hysteresis at Stall as an Unsteady Boundary-Layer Phenomenon

Description: "Analysis of rotating stall of compressor blade rows requires specification of a dynamic lift curve for the airfoil section at or near stall, presumably including the effect of lift hysteresis. Consideration of the Magnus lift of a rotating cylinder suggests performing an unsteady boundary-layer calculation to find the movement of the separation points of an airfoil fixed in a stream of variable incidence. The consideration of the shedding of vorticity into the wake should yield an estimate of … more

An Experimental Investigation of the Base Pressure Characteristics of Nonlifting Bodies of Revolution at Mach Numbers From 2.73 to 4.98

Description: Report presenting an investigation in the supersonic wind tunnel to determine some of the base pressure characteristics of related bodies of revolution at zero angle of attack. Results regarding variation of pressure over the base, variation of base pressure with Reynolds number, effect of nose and afterbody shapes, variation of base pressure with Mach number, and correlation of base pressure data are provided.

Production Test 105-8-MR, Supplement A: Uranium charging during reactor operation

Description: This memorandum describes a test which is to demonstrate the feasibility of routinely charging uranium slugs during reactor operation into tubes of the highest available powers and to provide functional testing of the equipment necessary to reduce such charging to a routine operation on all tubes in the reactor. This test will authorize the installation and routine operation of improved equipment for charging and discharging uranium during reactor operation on five central process tubes at C Re… more

Continuous effluent water high temperature monitor for B, C, D, DR, F, and H piles

Description: Continuous monitoring of the pile outlet water temperature may offer definite advantages from both the operating efficiency and pile safety points of view. The temperature data could be continuously displayed which would provide Operators with the kind of information required to operate efficiently while remaining within specified tube outlet water temperature limits, and permit tube outlet water temperatures to be continuously in the scram circuit, thus contributing to safety of operations.

Aluminum Canning of Nickel-Plated, Hanford Four-Inch Uranium Fuel Slugs by Hot-Pressing

Description: Conditions of time, temperature, and pressure for hotpress bonding of aluminum-nickel and uranium-nickel disks were determined experimentally. A process for jacketing Hanford four-inch slugs, coated with nonporous nickel electroplates, in aluminum cans by cold-sizing and hot-pressing was developed and conditions of time, temperature, and pressure required for the actual canning process were determined.
