Sufficient test work has been performed to indicate that radial vane type separators can meet the design requirements for boiling water superheat reactor application. Exit moisture less than 6％ by weight was obtained with k-inch radius vanes with inlet qualities ranging from 6 to 12 percent for 1000 psig saturated steam-water flow rates up to 9500 ft3/hr per inch of vane spacing. Carryunder measure¬ments were less than 0.2 percent on occasions and indicate that this limitation can be met or very nearly approached in reactor operation of radial vane separators.
