The pipe pitches would vary with Pn level which is related to the blanket structure design.
Helium is employed to cool the first wall and the blanket structure.
For example, the expansion of pebble beds restrained by blanket structure exerts stresses on the pebbles as well as the blanket structure wall, which might cause the pebbles to break and jeopardise the blanket operation.
The impact of corrosion includes deterioration of the mechanical integrity of the blanket structure due to the wall thinning.
These analyses have shown and quantified different time instants for the thermal transient on different parts of the blanket structure.
In this paper, we proposed simplification of blanket structure without decreasing the net Tritium Breeding Ratio (TBR).
Helium is used to cool the first wall and blanket structure, and the self-cooled Pb-17Li breeder is circulated for power conversion and for tritium extraction.
For monotonic damage modes, the blanket structure shows a global satisfying behavior in immediate plastic collapse and plastic instability damage modes, and thermal creep damage mode.
Safety and environmental assessments have been made of conceptual fusion power plant designs employing silicon carbide composites (SiC/SiC) as the first wall and blanket structure material.
Helium is used to cool the first wall and blanket structure, and the self-cooled breeder Pb 17Li is circulated for power conversion and for tritium breeding.
