Final report -- PT-105-548-A, The effect of masonite burnout on shield attenuation properties

Description: In a previous study it was determined experimentally that heat deterioration, or burnout, of the shield masonite is more severe than radiation damage under existing and proposed operating conditions. Higher shield temperatures, which are expected to result from increased power levels, fringe enrichment, and higher graphite temperatures, will markedly increase the rate at which the masonite burns out. The laminated iron-masonite biological shield will lose, as a result of burnout, the hydrogen a… more

Reduction of the amount of dichromate added to pile cooling water. Final report, PT-105-542-E

Description: Sodium dichromate has been tested for use as a process water corrosion inhibitor at a concentration of 0.5 ppm. The test was conducted by operating one half of D Reactor with 0.5 ppm while the other half operated at the normal concentration of 2 ppm sodium dichromate. A concentration of 0.5 ppm was found to be as effective a corrosion inhibitor as the normal concentration of 2 ppm except under one very important set of circumstances. If the reactor process tube ribs were previously worn or corr… more

A theoretical and experimental study of planing surfaces including effects of cross section and plan form

Description: A summary is given of the background and present status of the pure-planing theory for rectangular flat plates and v-bottom surfaces. The equations reviewed are compared with experiment. In order to extend the range of available planing data, the principal planing characteristics for models having sharp bottom surfaces having constant angles of dead rise of 20 degrees and 40 degrees. Planing data were also obtained for flat-plate surfaces with very slightly rounded chines for which decreased li… more

Description: Report presenting one-tenth-scale models of two inlet configurations of fighter-type aircraft have been tested in the 4- by 4-foot supersonic pressure tunnel. The pressure-recovery and force characteristics of the inlets were determined as a function of mass-flow ratio, angle of inlet compression, angle of attack, and Mach number.

Jet effects on base and afterbody pressures of a cylindrical afterbody at transonic speeds

Description: An investigation of the effects of jet nozzle geometry, size of base annulus, and base bleed upon the base and afterbody pressures of a cylindrical afterbody at transonic speeds has been conducted. Sonic and supersonic conical nozzles with jet-to-base diameter ratios from 0.25 to 0.85 were investigated with a cold jet at jet total-pressure ratios up to approximately 8.0 through a Mach number range from 0.6 to 1.25. Base pressure coefficients of about -0.55 were measured for the sonic nozzles at… more

Summary report on Columbia University heat transfer studies

Description: Experimental investigations were undertaken at Columbia University to determine the heat transfer and fluid flow characteristics of fuel elements for the Savannah River reactors. Primarily the tests simulated quatrefoil operation, but a number of tests directly applicable to the operation of extended surface fuel elements were performed. Data books were published in which the experimental data are tabulated.

Chemical Separation of Isotopes Section Semiannual Progress Report for Period Ending June 30, 1955

Description: The countercurrent gas-liquid system BF3(g)—anisole·BF3(l) for the concentration of boron isotopes has been studied. The single-storage separation factor varies from 1.039 at 0°C to 1.029 at 30°C. Rate of exchange is rapid, and, with efficient contacting equipment, complete exchange may be obtained in less than 15 sec. A total separation of 1.525 has been realized in laboratory equipment. The critical-product reflux reaction is quite efficient. Only about 55 moles of BF3 remain in each million … more
