The condenser is an important device for the operation of power plants in particular for pressurized water reactors. Undesirable transients may lead to the automatic shutdown of the power plant.
To simulate the complex dynamic physical behaviour of the condenser; a dynamic model has been developed using Modelica. The component model is meant to be used for power plant modeling and simulation with the ThermoSysPro library developed by EDF and released under open source license.
The transient most unfavorable to keeping the integrity of the condenser vacuum is the loss of the cold source pumps followed by a turbine trip and a missed islanding (house load operation).
The objective is to study the evolution of the pressure of the condenser for this kind of transients. During the transiernt; the condenser pressure should be always less than 5e4 Pa.
The present paper describes in detail the condenser model: hypothesis; governing equations; correlations and the test-case (structure of the test model; the parameterization data and the results of simulation).
