Annual Report 1961

Description: This seventh Annual Report is a summary of some of the progress in scientific and engineering research and development carried on at Argonne National Laboratory during 1961. As is customary in this series, only those portions of the total program that have reached such a stage that they may be of general interest are recorded. Thus, a comparison with the Annual Reports for 1959 (ANL-6125) and for 1960 (ANL-6275) will reveal the description of a generally different set of scientific activities. … more

The Application of Inert Fluidized Beds to the Volatility Reprocessing of Reactor Fuels

Description: In the reprocessing of spent solid fuels from nuclear reactors by direct volatilization, one of the major problems is the removal of heat from the highly exothermic gas-solid reactions. The use of fluidized beds of inert granular material as heat transfer media to control these exothermic reactions forms the basis of one approach to volatile reprocessing which is under development at BNL The engineering scale work carried out under this development program is discussed.

Broad Range Spectrograph for Use With the Rochester 27" Cyclotron

Description: "A broad range nuclear spectrograph of the Buechner-Bainbridge type, which characteristic radius R-50 cm. has been constructed and installed for use in conjunction with the Rochester 27" variable energy cyclotron. For a given magnetic field, particles are focused over an energy range 0.63o‹E‹1.3Eo, where Eo is the energy of particles focused with orbit radius Q-R-50 cm. The resolution of the spectrograph ∆E/E is less than 0.2%. Particles may be recorded either in nuclear emulsions or in an arr… more

Calibration of G.M. Counters For Direct Counting of Radon in the Atmosphere

Description: An experiment has been carried out for the direct calibration of a Geiger-counter immersed in a balloon containing a known concentration of radon in equilibrium with its daughters. A theory was developed for finding out the geometrical efficiency of the counter used in this way, and for checking the experimental results with theoretical efficiency. The counters calibrated in this way may be useful for the direct measurement of radon in uranium mines and may also be useful for monitoring radioac… more

Cesium-137 and Strontium-90 in Milk

Description: Cesium-137 and strontium-90 levels in liquid milk samples from Bombay and 27 other stations in India, and powder milk samples from Australia, Denmark, Holland, India, U.K. and U.S.A/ have been estimated. The results of these measurements have been interpreted on the basis of the total injection of these isotopes in the atmosphere, their rate of fallout, and seasonal effects.

Chemistry of Anhydrous Systems Containing Hydrogen Fluoride and Nitrogen Oxides

Description: Nitrosyl and fluoride ions are formed in liquid anhydrous hydrogen fluoride when nitric oxide, nitrogen sesquioxide, nitrogen tetroxide, or nitrosyl fluoride, are dissolved. Vapor infrared analysis was used to study the solution composition and gaseous reaction products. These solutions react with metallic uranium, plutonium, zirconium, iron, and aluminum, as well as ceramic uranium oxide and uranium carbide, forming soluble nitrosyl metal fluoride complexes and liberating nitric oxide. The ura… more

Coolball, a Machine Code for Thermal Analysis of Pebble Bed Reactor Cores

Description: COOLBALL is an IBM 650 machine program designed to calculate local gas and ball temperatures, gas flow, and pressure loses as induced by non-uniform power generation and voidage within an axial flow Pebble Bed Reactor core. This code has been used extensively to study the thermal characteristics of Pebble Bed Reactor cores in support of a broad program for the development of the PBR concept.

The Decontamination and Recovery of Precious Metals

Description: "This report is the third quarterly report under Contract AT(30-1)-2528 for the decontamination and recovery of precious metals from contaminated scrap. The results described in [2nd quarterly report] and expanded in this report confirm the statement that the method achieves not only the desired decontamination but also produces a product of high purity. In addition the relative simplicity of the method makes it particularly adaptable to large scale manipulation."

Determination of Particle Size Distribution by X-Ray Absorption

Description: "As it is frequently necessary to know the distribution of particle sizes in various products used in industrial applications, a number of means have been devised for these determinations. Some of them include direct microscopic measurement, screening of product, extraction of samples from a settling slurry as with the Andreasen pipette, air and liquid elutriation, adsorption of gases and liquids, and light absorption."

Electrostatic Classification of Submicron Airborne Particles : Progress Report, April 15 to June 15, 1961

Description: Abstract: "This program is a study of the basic variables that affect electrostatic classification of heterogeneous aerosols of submicron size,especially below 0.1[mu]. The variables of interest are particle size, concentration, composition, shape, and initial charge. During this period research was concerned with classifying particles as small as 0.01[mu]. This research included work on an aerosol generator for monodispersed 0.015-[mu] gold particles. The performance of the charger was further… more
