From abstract: "The effects of solution concentration and acidity on extraction of uranium by diethyl ether have been investigated... The approximate solubility of vanadium pentoxide in nitric acid was determined."

From abstract: "Results are presented which suggest the possibility of satisfactorily extracting uranium from pitchblende feeds with neutral ether, without the necessity of removing sulfate, by the addition of a sufficient quantity of iron to the feed." Other factors' effects on extraction were tested and arsenic was traced throughout extraction.

This quarterly progress report discusses topics of research and experimentation at the Oak Ridge National Laboratory, including inorganic chemistry, nuclear chemistry, radio-organic chemistry, chemistry of separations processes, chemical physics, radiation chemistry, chemistry of the solid state, instrumentation, reactor chemistry.

Management of first-cycle wastes from the Bismuth Phosphate Plant using Nickel Ferrocyanide scavenging is described.

Abstract: "A magnetohydrodynamic model of a plasma-magnetic field instability, using liquid sodium, has been observed. The growth rate and wave length of the Taylor-type acceleration instability was observed to be in agreement with the theory of Kruskal and Schwarzschild."

Introduction: This note describes briefly the current concept of the experimental program on source development for mirror machines. There are two major facilities involved: (1) A comparatively small machine whose code name is "Guppy", and, (2) A larger d.c. mirror geometry whose code name is "Waldo."

Abstract: "A magnetohydrodynamic model of plasma-magnetic field instabilities, using liquid sodium, has been observed. The growth of flutes in the mirror geometry was observed for the case of [beta] = NKT/H²/8w = 1."

Introduction: This report is intended to cover the activities of the Nuclear Power Section during the period from 30 September 1954 to 30 September 1955 under the terms of the USAEC Agreement.

Three methods are discussed for detecting ionizing radiation and transitting the intelligence. All three methods make use of the reactamce variation of a frequency determining network, to vary the frequency of an R.F. transitter as a function of ionizing radiation entering an ion chamber or counter. The first method is based on the capacitance znd subsequent frequency variation of am electrometer incorporated in an ion chamber. The variation is achieved by a moving came electrometer, where the position of the vane changes as a function of the leakage of an electrostatic charge when exposed to radiatioz and thus varies the electrometer capacitance. Gamma, beta particles, and fast neutrons were measured during these experiments. The second method replaces the moving vane electrometer by ferroelectric capacitances. This reduces the sensitiwity, but permits movement of the instrument during exposure. These ferroelectric capacitances are physically very small and can be enclosed inside of an ion chamber. The varintion of the capacitance with charge or voltage permits measurement of the ionination current as a function of capacitance and frequency. The third and most successful method replaces the ion chamber by a Geiger counter, single pulses and integrated pulse rates can be measured and transmitted. (auth)

"Tests have been made in the Langley 4- by 4-foot supersonic pressure tunnel at Mach numbers of 1.41, 1.61, and 2.01 of various arrangements of a 0.04956-scale model of the Convair F-102A airplane with faired inlets. Tests made of the model equipped with a plain wing, a wing with 6.4 percent conical camber, and a wing with 15 percent conical camber. Body modifications including an extended nose, a modified canopy, and extended afterbody fillets were evaluated" (p. 1).
