Loss of Normal Feedwater

lf2

EFW was initiated only in 3 of the 4 steam generators. The loop temperatures show little difference between the fed and unfed loops in MHI’s analysis.  So they are not presented here.  In MHI’s study the pressurizer PORV opened briefly after loss of feedwater.  PCTRAN’s result shows RCS pressure increased but not to the PORV opening set point.
Other than that everything is quite comparable.
