Abstract: Within the framework of the European power plant conceptual study (PPCS), different helium-cooled
divertor concepts based on different heat transfer mechanisms are being investigated at ENEA Frascati, Italy, and
Forschungszentrum Karlsruhe, Germany. They are based on a modular design which helps reduce thermal stresses.
The design goal is to withstand a high heat flux of about 10-15 MW/m2, a value which is considered relevant to
future fusion power plants to be built after ITER. It is an additional challenge that many physical and materialspecific
factors of the future reactors are unknown. A first design approach and the state of the art of divertor
development shall be subject of this report.
