MTR Technical Branch Quarterly Report for First Quarter - 1954
The following report is a quarterly report for first quarter in 1954 for the Phillips Petroleum Company. During the first quarter of 1954 considerable progress was made on the design, construction and testing required to initiate work on new programs. The result of this is the beginning construction and design on the Reactivity Measurement Facility.

Design and economic study of hot off-gas storage system
From introduction: "One of the most important factors which must be considered in the chemical processing of spent fuel elements is the safe and economic disposal of gaseous radioactive fission product wastes given off in the fuel element dissolution operation. For this reason work is underway at ORNL to study the various gas disposal methods that might be used to handle the radioactive fission product gases, krypton, xenon, and iodine."

Efficiency of a Three Inch Higgins Column
The following report describes the usage of a semi-continuous ion exchange contactor--named the Higgins contactor--fit to operate the Purex process, a process that recovers plutonium and uranium from irradiated natural uranium fuel elements. It is intended to use the contactor in the final purification and concentration stage of the process plutonium streams.

Expressions for Conversion Ratio in a Th-U²³⁵ Converter
"This memo shall be an attempt to write down in a consistent manner some expressions for conversion ratio so that a comparison can be made with regard to a uniformly loaded core versus a flattered zone surrounded by an unloaded region. The discussion will be limited to the type of loading that is at present being considered for the reactor - a checkerboard array of MTR fuel elements and feed elements; the unloaded reactor will consist of fuel elements only."

The Chlorination of TO₃
Abstract: The applicability of specific mixtures and organic chlorocarbons in general toward the chlorination of TO₃ has been tested by means of reactions is sealed glass tubes. The results show that thionyl chloride mixed with tetrachloroethylene or a bromothane of the tyoe CHBrC12 will produce TCI4 directly. This same result is produced by CBr2C12 alone.

Theoretical Consideration of the Geometrical Structure of the Uranium Halides
Abstract: The geometrical structure of the uranium halides has been studied from a theoretical viewpoint. This theoretical consideration tends to indicate that the pentavalent uranium halides are geometrically but not energetically capable of existence except as double halide compounds of hexavalent and tetravalent uranium.

Neutron Economy of Various Converter Reactor Designs
The following report determines how many neutrons are being absorbed in various converter reactor designs, how many neutrons leak from the reactor and the breakdown between fast and thermal leakage. Another interest this paper examines is to determine how many neutrons are absorbed in thorium in the resonance region, at thermal energy, and in the blanket.
