HYDRAULIC INSTABILITY IN A NATURAL CIRCULATION LOOP WITH NET STEAM GENERATION AT 1000 PSIA
Technical Report
·
OSTI ID:4140419
The performance of a natural circulation loop was studied at 1000 psia. Tests were performed with rods heated electrically inside a pipe. Test results reveal that flow instability occurs at lower steam qualities and higher flows as the inlet subcooling is increased. Oscillatory conditions were obtained for calculated exit void fractions rangtng from 0.6 to 0.9. Data are included on several instability conditions for fixed systems at given pressures, and their variations with heater and system geometry. (J.R.D.)
