ABSTRACT
The article discusses a methodology to assess the adequacy of the feedwater system and check if the deaerator pressure transient can be handled by the boiler feed water pump. A deaerator pressure transient is a rapid loss of deaerator pressure during a steam turbine generator trip or unexpected decrease in load on the steam turbine generator. The methodology discussed in the article includes determining the net positive suction head (NPSH) margin, deaerator pressure decay, and its effect, and residence time.
