TL;DR: The authors summarizes the design and performances of recent breeding blanket concepts and identifies the key material issues associated with them, by balancing out the potential performance of the concepts with the risk associated with the required material development.
104 citations
TL;DR: In this article, an advanced dual coolant (A-DC) blanket is investigated in the frame of the long-term power plant conceptual study (PPCS) and the status of the work with some idea improvements is reported.
57 citations
TL;DR: The European breeding blanket R&D for DEMO is focussed on the development of two concepts: the Water Cooled Lithium Lead (WCLL) and the Helium Cooled Pebble Bed (HCPB) as mentioned in this paper.
29 citations
TL;DR: The Testing Programme for the EU Helium Cooled Pebble Bed (HCPB) Blanket concept is presented and the general external design of these modules is similar, but internals, instrumentation and operation mode will be different to cope with the specific testing objectives.
20 citations
TL;DR: The helium cooled pebble bed (HCPB) blanket is one of the two DEMO blanket concepts proposed for testing in international thermonuclear experimental reactor (ITER), and the purpose of the tests is to validate the design principles and the operational feasibility for the demonstration blanket system.
15 citations
TL;DR: To ensure sufficient support over the long development time, it has to be shown in a credible way, that there are feasible blanket concepts for fusion power plants which can be developed with a high confidence of success, and the final product will be an attractive power plant which could be operated safely, with minimum impact on the environment, and at an acceptable cost of electricity.
12 citations
TL;DR: In this paper, a design solution for the European Helium Cooled Solid Breeder Reactor that allows transporting the heat from the inboard to the outboard side with a passive cooling system located in the VV and based on natural circulation of liquid lead is presented.

TL;DR: In this article, a new FZK He-cooled modular divertor concept with integrated pin arrays (HEMP) is introduced, which has the potential of resisting a heat flow density of at least 10-15 MW/m 2 at a reachable heat transfer coefficient of approx. 60 kW/m2 K and a reasonable pumping power.
Abstract: Application of a helium-cooled divertor together with the dual-coolant blanket concept is considered favourable for achieving a high thermal efficiency of the power plant due to its relatively high coolant outlet temperature. A new FZK He-cooled modular divertor concept with integrated pin arrays (HEMP) is introduced. Its main features and function are described in detail. The result of the thermalhydraulic analysis shows that the HEMP divertor concept has the potential of resisting a heat flow density of at least 10-15 MW/m 2 at a reachable heat transfer coefficient of approx. 60 kW/m 2 K and a reasonable pumping power. Integration of this divertor concept into the power conversion system using a closed Brayton gas turbine system with three-stage compression leads to a net efficiency of the blanket/divertor cycle of about 43 %.
