Voidage in a serpentine geometry nuclear boiler tube

  • 1. Marchwood Engineering Labs., Southampton, England

Description

Dynamic stability threshold predictions for the once-through AGR boilers were found to be sensitive to voidage input values. Since reliable data were lacking, measurements of voidage were undertaken on a full-size serpentine boiler tube operating under representative plant conditions by use of gamma-densitometry. These measurements involved multi-chordal scanning with subsequent integration over the tube cross-section to minimize errors in mean fluid density determination. Slip ratios were computed assuming equilibrium between phases
