Historical: This process is based on experimental work done in Jackson Laboratory, Send Works, Blue Products, and East Area. It supersedes the Tentative Chambers Works Process for the Manufacture of Fluorine Using Carbon Anode Units, dated December 2, 1943.

Abstract: Presented herein is the preliminary design of a natural uranium, graphite moderated, CO2-cooled reactor and power plant similar to, but larger than, the British Calder Hall plant, with a net electrical output of 130 MWE.

From Abstract: "The report is concerned with a theoretical analysis of the experiment known as the Calibration of the 3" Cross Control Rod. The experiment provided 29 points on a curve of reactivity (in hours per centimeter) versus depth of control rod insertion. An attempt to reproduce this curve theoretically has been quite successful."

Introduction: "The ionization region in the Nier mass spectrometer is customarily constructed of copper. Various other metals were tried for this purpose; among them tantalum and molybdenum, with both metals it was found that a spectrum of the fluoride of the metal appeared when uranium hexafluoride was admitted. It was thus possible to produce tantalum fluoride with comparative ease and to make a critical examination of the mass spectrum to set an upper limit of abundance of tantalum isotopes. For positive identification, a line must appear in all ion positions in the same abundance, relative to the main line. It must be shown that any lines which appear are not contributed by other elements or compounds."

This technical report presents "a theoretical study of the motion of gas bubbles in a rotating liquid" in order to "make comparison with experimental data from an investigation concerning the removal of gas bubbles from rotating liquids as descriped in ORNL-630." The report presents a literature review of "motion of gas bubbles in liquids" and provides a "summary of extensive experimental studies at the University of Tennessee." It also presents "an expression for the radial velocity of a gas bubble in a rotating liquid based on principles of mechanics." Finally, this report presents "a method for computing the steady state state [sic] gas hold-up in the HRE reactor core under power producing conditions." (From introduction)

SNAP II is the designation for a 3 KW nuclear auxiliary power unit to be used in a satellite vehicle. The SNAP II system consists of a reactor heat source, a mercury Rankine engine and an alternator. A two stage, full admission, axial flow turbine was chose for the APU application. Design details and test results are presented in this report. This work was performed under a subcontract to to Atomics International as part of the Atomic Energy Commission Contract No. AT(11-1)-GEN-8.
