Effects of dissolved gas and downstream geometry during blowdown of a subcooled liquid. [PWR]

PDF Version Also Available for Download.

Description

The effects of dissolved gas and downstream geometry during a blowdown transient were investigated experimentally. It was observed that dissolved gas did not significantly affect the blowdown process if no additional surface was available in the test section to provide nucleation sites. However, if sufficient nucleation sites were available in the system, large amplitude, continuous pressure oscillations were observed when the system contained a large amount of dissolved gas. The delay in blowdown times caused by these oscillations is between 20 to 30%. A single-phase, incompressible, quasi-steady model was developed to predict the pressure history in the blowdown vessel and ... continued below
