Abstract

The purpose of the present experimental research is to provide experimental data in a design field where existing burn-out correlations are usually extrapolated outside their validity range. Low surface heat fluxes and very long geometries typical of L.M.F.B.R. sodium heated steam generators require full scale water tests. 218 burn-out qualities at pressures ranging from 60 to 160 kg/cm2 and specific mass flowrates from 110 to 260 g/cm2s have been measured and tested against the most known burn-out correlations. Physically it appears that burn-out quality is substantially independent from the flowrate, while a sharp subdivision with pressure suggests that for 60<p<90 kg/cm2 and 110<p<160 kg/cm2 two different burn-out mechanisms may set up.
