Present techniques for measuring sound velocity in liquid metals have been limited by transducers that cannot survive in extreme temperatures for the long periods these techniques require. The report describes work on a dynamic noncontacting method intended to measure sound velocity in liquid uranium. Measurements were successful with liquid lead, but not with liquid uranium. Flat slab specimens were found to give much better response than cylindrical shapes.

The Aerospace Corporation is providing technical analysis support services to the DOE Transportation Energy Conservation Division. The work to be performed by The Aerospace Corporation for the DOE/TEC is confined to the following basic task areas: (1) technical support of ongoing research and development programs in energy efficient transportation systems; (2) analysis for the future commercialization of transportation technologies; (3) new concept evaluation program support; (4) technical evaluation of new concepts, inventions, and ideas; (5) assessment of technological and other factors on the implementation and utilization of transportation in the United States; and (6) program planning analysis and documentation. Progress is reported in the areas of heat engine systems, alternative fuels utilization, nonhighway transport systems, and electric and hybrid vehicles. (WHK)

Recycle preparation methods were evaluated for secondary aqueous waste streams likely to be produced during reactor fuel fabrication and reprocessing. Adsorption, reverse osmosis, and ozonization methods were evaluated on a laboratory scale for their application to the treatment of wastewater. Activated carbon, macroreticular resins, and polyurethanes were tested to determine their relative capabilities for removing detergents and corrosive anions from wastewater. Conceptual flow sheets were constructed for purifying wastewater by reverse osmosis. In addition, the application of ozonization techniques for water recycle preparation was examined briefly.
