Progress is reported in modification and finalization of equipment design. Equipment specifications are near completion for each phase of the experimental progranm. K will be boiled in a forced circulation loop where quality and flow rate effects on the heat transfer coefficient will be studied. Pressure drop and void fraction measurements will be made in a second test section to learn more about two phase flow behavior with metallic fluids. A pool boiler will be used to study pressure effects and to increase the temperature and flux levels beyond the 1800 deg F and 10/sup 6/ Btu/hr-ft/sup 2/ anticipated in the loop. Film boiling of K will be studied using condensing Na or Li as a heat source. A Nb vessel will be used thus making it possible to increase the range of surface temperatures. Initial agravic experiments will utilize mercury pool boiling from a stainless surface with normal accelerations up to 20 g's. Fabrication of equipment is expected to begin during the next quarter.
