Object-Oriented Modeling, Simulation and Control of the IRIS Nuclear Power Plant with Modelica

Abstract

The paper presents the application of the Modelica language to the modeling, simulation, and control of the new IRIS nuclear power plant, under development by an international consortium. The plant model, developed by using components from the ThermoPower library, as well as custom-built nuclear components, is described, as well as the digital control system model, which will eventually become very realistic. Special emphasis is put on the use of inheritance and replaceable objects for the management of a family of model variants over the project life-time. Selected simulation results are included.
