The Chelate Process I

Description: The chelate process for the extraction and decontamination of plutonium has been investigated. The process is designed as an alternate process for ihe Hanford type operation. The basic chemical factors have been studied and two flowsheeis have been developed and tested for recovery of plutonium. An over-all yield of plutonium in excess of 99% is reported for one flowsheet using benzene as the organic solvent and 98.5% when toluene was substituted for benzene. The general factors involved in est… more

THE CHEMISTRY OF THE REACTION OF URANIUM HEXAFLUORIDE WITH ACTIVATED CARBON

Description: The effects of temperature, time and other variables on the rate and extent of reaction between UF/sub 6/ and various types, grades and particle sizes of commercial activated carbon have been studied experimentally. It is shown that both hydrolysis and reduction of the UF/sub 6/ occur, the latter more slowly than the former. Reduction leads to the formation of a mixture of fluorocarbons ranging from CF/sub 4/ to a wax-like maternial volatile only above 250 deg C. There is also evidence for the … more

Graphite expansion committee meeting of December 6, 1946

Description: The twelfth meeting of the Graphite Expansion Committee was held on December 6, 1946. A summary of the meeting is as follows. Recent laboratory studies suggest that the rate of graphite expansion decreases with exposure when the samples are exposed in an air atmosphere at ambient pile temperature, through the relative effects of atmosphere and temperature are not known. These observations are in qualitative agreement with the decreased rate of vertical expansion of the piles. The neoprene seal … more

Knock-Limited Performance of Triptane and Xylidines Blended with 28-R Aviation Fuel at High Compression Ratios and Maximum-Economy Spark Setting

Description: From Summary :"An investigation was conducted to evaluate the possibilities of utilizing the high-performance characteristics of triptane and xylidines blended with 28-R fuel in order to increase fuel economy by the use of high compression ratios and maximum-economy spark setting. Full-scale single-cylinder knock tests were run with 20 deg B.T.C. and maximum-economy spark settings at compression ratios of 6.9, 8.0, and 10.0, and with two inlet-air temperatures. The fuels tested consisted of tri… more

A Mass Spectrograph for the Analysis of Fission Product Mixtures

Description: From introduction: "The analysis of mixtures of fission products with a mass spectrograph offers certain advantages. A chemical separation of the fission products found in the solution at Hanford is not necessary with the mass spectrograph technique. A sample of the mixtures can be placed on the sample holder and then the sample holder is mounted in the mass spectrograph. This reduces the amount of handling of the active solutions to one relatively simple and short operation. The health hazards… more

A Mathematical Analysis of the Calutron

Description: Abstract: "The definitions of the fundamental measures of calutron operation including enhancement, current ratio, and process efficiency are set forth with derivations of the relationships between them. An analysis of the plant process is carried out for both the tanks limited and the charge limited case. Equations are derived for plant X output and plant X utilization efficiency. Effective production is defined and the value of increment to a mass of product material in terms of effective pro… more
