Nuclear Power Station Deaerator Transient Study

Studying how it develops about the thermodynamics parameters of feedwater systems in case of the load rejection conditions about nuclear power station,building mathematical control models,a program software which can simulate the conditions is built up,and the deaerator pressure, feedwater temperature, Net Positive Suction Head Available（NPSHA） for feedpump are worked out.The results can help supply a better data about the height of deaerator and a efficient control measure that keep the feedpump safe under the transient condition.
