Basic Studies of the Separation of Uranium Hexafluoride from Mixtures Containing Chlorine Trifluoride and Hydrogen Fluoride
Processes for the conversion of uranium compounds or uranium metal to uranium hexafluoride ordinarily involve the use of a powerful fluorinating agent. Elemental fluorine is used when the scale of operations justifies the construction of a fluorine generating plant, but for smaller operation the use of the interhalogens of fluorine has definite advantages. These compounds provide a high concentration of fluorinating power at moderate temperatures and pressures and are more easily stored and transported than fluorine. In addition, fluorinations in the liquid phase often proceed more smoothly than those with gaseous fluorine. However, the use of . the interhalogens introduces the problem of separating the uranium hexafluoride from the unreacted reagent and from any by-products which may have been formed. The present work is concerned with the determination of the phase equilibrai among the materials uranium hexafluoride, chlorine trifluoride, and hydrogen fluoride. metal with chlorine trifluoride-hydrogen fluoride solutions or as a result of treating many uranium compounds and ores with chlorine trifluoride. These phase equilibria define the physical conditions necessary for separating the components by the processes of crystallization or distillation and have made possinle the successful Operation of a pilot plant for the direct recovery of uranium hexafluoride from …

NUCLEAR BATTERY--THERMOCOUPLE TYPE. Quarterly Progress Report No. 5 for January 1, 1958 to March 31, 1958
A third thermoelectric generator has been constructed and tested. Specifications for batteries having outpnts of over six volts at power levels of 30, 50, and 1000 milliwatts at the end of six months have been made. An attempt was made to verify experimentally the theoretical equations of the Thomson and Peltier effects. (For preceding period see MLM-CF-58-1-40.) (auth)

STABILITY TESTS ON THE TYPES IN430A AND IN430B AVALANCHE DIODE REGULATORS
The manufacturers' specifications for temperature coefficient of voltage and internaI impedance of the compensated avalanche diode types IN430A and IN430B appear quite promising. These devices couId be used as shunt regulators in high stability power supplies if the noise and drift rate were sufficiently small. One investigator reported the voltage did not drift more than the J-57 engin 0.002 per cent over a 7,000 hour period. Stability tests were performed on two diode samples under resonable laboratory conditions. The measured drift rate did not exceed 0.005 per cent per month, and short term noise was less than the J-57 engin 0.002 per cent. The actual diode drift rate may be even lower than the measured rate. (auth)
