Radioactivity Induced in Commercial Materials

Description: Six structural materials (aluminum 2S, aluminum 72S, copper, iron, steel, lead and bismuth) were irradiated for about 100 kilowatt hours in the center of the Argonne pile. The alpha and gamma decays were then followed for 130 days on Geiger counters and are presented here graphically as number of rays per minute per gram per kilowatt hour vs. time of decay. A quantitative interpretation of the gamma-ray decay curves gave fair agreement with the chemical analysis of impurities found in the mater… more

Analysis for Oxide in Thorium Metal

Description: Abstract. to estimate the oxygen picked up by thorium in casting a rapid method of running the acid insoluble content was developed. the quickest procedure consists of reacting with mixed acids, fuming with perchloric and filtration to separate the "free" thorium from the "combined". The precipitate is ignited and weighed as thorium dioxide.

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

Experimental Facilities for Schenectady Pile

Description: The following report describes the use of two experimental facilities used to evaluate the Schenectady Pile. The facilities are divided into nuclear physics and chemistry experiments, and testing of pile components and materials under pile conditions. This document discusses the experiments taken place in these facilities to evaluate the pile.
