A saturated Na pool boiling experiment is described in which the test section was a horizontal, 3/8-in.-diameter, electrically heated cylinder. Measurements of surface temperature and heat flux during nucleate boiling were made at pool temperature between 1200 and 1500 deg F and at heat fluxes up to 800,000 Btu/hr-ft/sup 2/. Burnout heat flux measurements were made at pool pressures between 0.5 and 1.5 psia. Empirical correlation of the nucleate boiling data showed heat transfer coefficients somewhat higher than previous predictions. A new nondimensional burnout correlation is derived which brings the Na measurements into agreement with published burnout values for water and various organics. This correlation predicts a burnout heat flux for Na pool boiling of 1.9 x 10/sup 6/ Btu/hr-ft/sup 2/ at one atmosphere, and it is recommended for burnout predictions for Na and other wetting liquid metals at pressures which are low relative to their critical pressure.
