Summary
Vaporization rates of sodium into the helium stream were estimated using the analogy between heat and mass transfer. Because of the high helium velocities existing in the fuel handling cask, essentially all of the sodium vaporized from the fuel element surfaces will be carried into the external circuit unless an entrainment separator is provided. Approximately one pound of sodium will be carried as mist and vapor from the cask during the initial 15 to 30 minutes of the fuel handling operation. The gas has a saturation capacity of 0.11 lb/hr of sodium. In the external heat exchanger, 0.11 lb/hr of mist will be forme This sodium should not deposit on the tubes because of the high flow velocity. To protect the heat exchanger and the blower, cyclone separators or wire mesh demisters are recommended. (auth)
