Engineering Development of Fluid-Bed Fluoride Volatility Processes. Part 5. Description of a Pilot-Scale Facility for Uranium Dioxide-Plutonium Dioxide Processing Studies

Engineering Development of Fluid-Bed Fluoride Volatility Processes. Part 14. Processing Experience in Fluorinating Plutonium Materials and Thermally Decomposing Plutonium Hexafluoride in the Engineering-Scale Alpha Facility.

“…The maximum bed temperature of 550°C was held arbitrarily for 5 When a run was finished, nitrogen was substituted for fluorine, the fluorinator heating circuits were shut down, and the bed was cooled by increasing the fluorinator coolant flow to the maximum.…”

A Conceptual Design Study of a Fluoride-Volatility Plant for Reprocessing LMFBR Fuels.

“…Scrubbers of the type used at ANL can be considered as series 155 and parallel combinations of a modular spray unit of 2 by 2 ft cross section and 4 ft length containing one hollow-cone spray nozzle that impinges on a throat piece of 1-ft ID. For a spray-nozzle flowrate of about 10 gal/min at 100 psi and an air flowrate of 1000 cfm, the modular spray unit has a capacity of about one transfer unit.…”

Generalized Computer Program for Flowsheet Calculation and Process Data Reduction.

“…The calculations are performed by a program called the equipment subroutine, which represents the process vessel. (6) When convenient, boxes may be used to represent imaginary process vessels, on both the process and information flowsheets. This is usually done to represent combination of two or more process streams, .…”
