Development of a thermal-hydraulic model for the dynamic simulation of the EU DEMO breeding blanket cooling loops. Part I: HCPB

A global thermal-hydraulic model of the EU DEMO tokamak is currently under development at Politecnico di Torino. The first module of the global model will simulate the blanket cooling system and it will have to be able to investigate different coolant options and different cooling schemes, to be adapted to the different blanket systems currently under development in the Breeding Blanket project. The paper presents the status and the first steady-state results obtained with the Helium-Cooled Pebble-Bed (HCPB) module of the EU DEMO blanket cooling loop system model. The model is based on an object-oriented approach using the Modelica language.
