The use of liquid alkali metals as a heat transfer medium or motive fluid for power conversion systems has increased significantly in recent years and has created new demands in the area of liquid alkali metal handling technology. Contaminants existing in liquid alkali metal systems may exert deleterious effects on thermophysical properties, corrosivity and handlin characteristics. This paper presents an analytical study on the physicochemical and kinetic aspects of liquid cesium purification, employing the hot gettering technique. The properties and various aspects of handling sodium, potassium, rubidium and cesium are reviewed. Typical sources of contamination are discussed. (Author).

This report describes a proposed information transfer program for the selection and approval of components used in Air Force systems. It is intended for use by designers and also by the management group approving what the designers recommend. A method is presented showing how technical characteristics are used as the basis for item selection. When a complete characteristic description is determined, an established index code substitutes numbers for the particular words thus permitting rapid machine search and retrieval. The program employs 1000-ft microfilm facilities for storage and retrieval. It features technical summaries of engineering data as the output for quick determination as to whether the selected items satisfy the requirement.

An assessment of working fluids for use in a high-temperature dynamic power conversion system is presented. The method of comparison of the various fluids consists of a preliminary design of the major system components. The results are presented as conversion system weights for the considered fluids, potassium, sodium, lithium, bismuth, and lead, at various values of turbine inlet temperatures. On the basis of the generated data, it has been concluded that only potassium and sodium are practical for use as a working fluid in the temperature range of consideration, 2000 to 4000 R. It is further concluded that potassium and sodium at turbine inlet temperatures from 2800 to 3200 R offer systems of sufficiently low weight to warrant further and more detailed investigations.

The scope of the Air Force materials research effort encompasses all advanced system requirements, as reflected by analysis of their mission profile, for which materials capability does not exist. To portray the vital role of materials, a review is made of serveral typical advance system concepts. The most critical materials problems, as represented by primary system components within the major areas of primary and secondary structure, environmental protection, electronics and energy transfer systems are discussed.
