C-616 UF$sub 6$ HYDROLYSIS FUMES
Experiments were carried out to determine how fast the concentration of suspended material decreases in fumes produced by the hydrolysis of UF/sub 6/ vapor in damp air. The rate of aggregation is a function chiefly of the number of particles per unit gas volume, but depends also on the chemical composition, size and shape of the particles, the temperature and pressure, and the degree of agitation. The rate of settling depends on the weight and shape of the particles and the viscosity of the gas. (W.L.H.)

Casting Uranium Bars as a Substitute for the Extrusion Process
The usual method of producing uranium slugs for the reaction pile is to cast the metal into billets which are extruded into rod about 1.45 inches in diameter. Slugs are then machined from this to the final size of 1.359 inches in diameter by 8 inches long. Extrusion is done in the gamma range at a temperature of about 1000 C, where the metal is soft enough to be extruded at relatively low pressures. This operation is difficult and expensive and the product is not entirely satisfactory. The billets must be protected from oxidation during heating and extruding and the extruded rod must likewise be protected during cooling. Loss of metal due to oxidation is appreciable and a relatively large amount of scrap is produced. The production of dies suitable for use at the high temperatures involved is troublesome. The extruded rod must be straightened before machining and frequently contains stringers of oxide and voids or other internal defects.

Technical Department report on Production Test No. 313-58-M: Recovery of lead dipped slugs
A number of slugs have been dipped in lead, then Al-Si and canned. Laboratory experiments showed that the can and outer bonding layers could be removed by the standard caustic-nitrate treatment. The alloy layer was removed from several slugs by hot nitric acid without use of hydrofluoric acid. It was desired to extend the method to the plant process and to clean accumulated lead dipped pieces. Lead dipped slugs may be cleaned by the regular recovery process with a weight loss of about 0.03 lbs. per slug. Attempts to modify or shorten the procedure were not successful. Twenty-four (24) of the recovered slugs were canned satisfactorily.
