In an attempt to overcome the disadvantages of the normal type of boiling water reactor, a new method of steam generation has been devised in which the relative positions of the liquid and vapor phases are reversed, the liquid phase being dispersed in the steam, instead of vice versa. The coolant can thus be regarded as a suspension of liquid droplets carried in an inert carrier gas or in their own vapor. The potentialities of such two phase systems as reactor coolants are being investigated experimentally, with reference to the steam-water system. Preliminary heat transfer rates and pressure drop data have been determined experi-mentally at substantially atmospheric pressure in an electrically heated test section for various steam qualities, total flow rates, and heat fluxes. These experi-ments have shown that in the case of steam-water mixtures the heat transfer coefficients lie within the range 5,000 to 10,000 Btu/ hr ft 2 deg F depending on the operating conditions employed.
