Purpose: "The Hanford Works Analytical Manual for Process Water is designed to specify the analytical methods to be applied for control purposes in the Reactor Section, Process Sub-Section laboratories. The procedures are in general form and serve as references rather than outlined laboratory instructions. The manual us designed to replace the "Hanford Works Manual," HW-12862."

In reduction reactions of CeO₂, with calcium and a CaCl₂ flux, the use of vibrational energy was shown to have a marked effect on the yield of coalesced metal. Buttons of 40 to 50% theoretical yield were obtained from the vibrated reductions. As the flux concentration is decreased, the slag becomes more viscous containing undissolved CaO. The undissolved CaO present prevents the metal from completely coalescing, but the metal can be recovered from the slag and coalesced under CaCl₂ containing a small amount of calcium to reduce any oxide skin present. Cerium pellet yields of 50 to 60% metal were obtained by the procedure and were not difficult to handle in air. Cerium was used as a stand-in material for plutonium.

The use of process-solution-lubricated sleeve bearings in rotating equipment is quite extensive at H.A.P.O. The difficulty or impossibility of providing contact maintenance, the poor lubricating qualities and corrosive natures of most of the process solutions, in addition to radioactivity, impose stringent restrictions on the selection of materials of construction of these bearings. Prototypical evaluation of materials indicating suitable characteristics in preliminary testing, both in the Corrosion Laboratory and in the bearing test machines, is necessary to establish behavior and compatibility under actual or simulated process conditions. These preliminary tests showed that gold and gold alloys might be used as satisfactory materials for pump bearings under certain conditions. This report presents the test results obtained while testing bearings in pumps prototypical or identical with process plant equipment.
