  hot leg
Hot leg U-bend vent valves were modeled as the principal noncondensable venting pathway.
      
This is because the calculated steam velocity in the hot leg was larger than the criterion for the horizontal stratification.
      
The void fraction in the hot leg was, however, underestimated.
      
There was one inlet cold leg and one outlet hot leg in operation.
      
The flow regime in the hot leg during this period was bubbly, and the stratified flow seen in the experiment was not calculated.
