Emphasis on the test program was temporarily shifted to study the effect of helium gas dissolved in the coolant stream on the subcooled boiling burnout heat flux for a large internally heated annulus. A new test section capable of achieving heat fluxes in excess of 2.5 x 10/sup 6/ Btu/hr-ft/sup 2/ was installed in the loop. Systems for injecting helium gas snd messuring the gas content of the water going to the test were also designed and fabricated. Experimental testing will begin early in June 1962. All the available two phase pressure drop data for high heat flux 19-rod test sections were analyzed, and it was shown that a simple plot of total pressure drop versus average steam quality at constant mass velocities might be more useful than the more complex Martinelli- Nelson type analysis.
